INTRODUCTION
There is ample evidence that marine resources of the Northwest Straits are in serious decline. Bottom fish, forage fish, salmon, sea birds, invertebrates, and some populations of marine mammals have declined precipitously since 1980. The Jefferson County Marine Resources committee is a citizen-based effort to identify regional marine issues, foster community understanding and involvement, recommend positive action, and develop support for various protection and restoration measures.
This annotated bibliography is a product of the Jefferson County Marine Resources 2000 literature review and data search on the status of marine resources in Jefferson County. Information was collected from an extensive review of existing literature. This included existing literature reviews, peer reviewed literature, agency reports, and a search of electronic databases for all documents pertaining to marine resources in Jefferson County with a particular focus on that region of Jefferson County that falls within the boundaries of the Northwest Straits Commission. Those marine waters bounded by the Hood Canal Bridge, San Juan County, Island County, and Clallam County is the primary area of focus.
This search included interviews with leading experts
and resource managers on specific species and ecosystem components and
included, but was not limited to, a search of the following electronic
databases: Aquatic Sciences and Fisheries Abstracts (ASFA), UW Fisheries
Research Institute Reports, the National Technical Information Service
(NTIS), and the University of Washington library database. The University
of Washington Library, UW Fisheries Research Institute Reports, and NTIS
electronic databases have unlimited internet access. The ASFA database
has limited on-line membership access but is available on compact disk
in the University of Washington, Fisheries and Oceanography library. The
ASFA database includes literature dating back to 1982 covering science,
technology, and management of marine and freshwater environments. It includes
5,000 international sources in the form of primary journals, source documents,
books, monographic series, conference proceedings and technical research
reports. The University of Washington library catalog has unlimited internet
access at http://catalog.lib.washington.edu/search~/. Numerous agency reports
and the UW School of Fisheries, Fisheries Research Institute Reports (UW-FRI)
database which includes over 500 reports pertaining to research conducted
by the Fisheries Research Institute (FRI) personnel from 1973 to the present
are also available on the internet. In addition to the above literature
and data search, information has been collected through interviews with
leading experts and resource managers. Through this process, we have assembled
a comprehensive collection of literature and information regarding the
status of marine resources in Jefferson County. In addition to this annotated
bibliography, the products of this data search process include: a Jefferson
County MRC on-line bibliography available on the MRC web site at http://mrc.co.jefferson.wa.us,
a summary report, and an enhanced literature collection for the Jefferson
County MRC physical library that is available to MRC members and interested
members of the general public.

Abstract: Although research has been conducted on the effects of oil on the giant kelp Macrocystis pyrifera, no similar studies have been completed on bull kelp, Nereocystis leutkeana, the dominant kelp in Washington State, British Columbia, and Alaska. The effects of three petroleum products [diesel fuel, intermediate fuel oil (IFO) and crude oil] were tested before and after weathering on N. leutkeana. Whole plants were exposed to petroleum product for 4 or 24 h and then transferred to the field. Observations on the condition of the plants were made daily for 7 d. In addition, controlled bioassays were performed to measure the effects of petroleum exposure on net photosynthetic rate (NP) and respiration rate, using light and dark-bottle techniques. These experiments verified the susceptibility of N. leutkeana tissue to the damaging effects of direct exposure to several oil types. The 4 h exposures to weathered diesel and unweathered IFO, and 24 h exposures to unweathered and weathered diesel and IFO resulted in moderate to severe damage to kelp tissue (i.e. resulted in moderate to severe damage to kelp tissue (i.e. clearly delineated bleached line accompanied by tissue necrosis). Weathered diesel was more toxic than unweathered diesel. The most severe damage to bull kelp was concentrated at the meristematic zone (junction of stipe and bulb) where new tissue growth occurs. Petroleum type significantly affected stipe and blade NP, R and NP:R ratios. Diesel treatments had a greater negative effect on NP than did the IFO treatments. Based on these experiments, the relative ranking of the damaging effects of petroleum treatment on bull kelp ware weathered diesel>unweathered IFO>unweathered diesel>weathered IFO>unweathered crude>weathered crude.

Keywords: fish//bottomfish//groundfish//cod//rockfish//lingcod//pollock//halibut
Abstract: WDFW is developing bottomfish management
plans that incorporate angler and diver preferences with the goal to conserve
fish resources. This report presents three general approaches for managing
recreational fisheries for bottomfish in Puget Sound. These approaches
represent various trade-offs between management simplicity and attainable
harvest. Information about existing recreational fisheries for bottomfish,
fish biology, and angler preferences, as well as expectations of increased
fishing effort, are reviewed and analyzed in the development of a recommended
management approach.

WDF investigated the sport fishery for Pacific cod (Gadus macrocephalus) in Agate Pass, WA. Between December 20, 1976 and April 10, 1977. It is estimated that 3,840 angler trips harvests 12,200 fish, calculated at 39,200 pounds total weight. The mean length was 50.3 cm females significantly the larger fish, and males outnumbering females in the catch. During the study, fish were tagged and recoveries indicated that the Pacific tomcod were moving rapidly through the pass in a generally southerly direction, diminishing the effect of the fisheries on a particular group of stock. Tag returns during the following year (1979) indicated a dispersion of the cod throughout Puget Sound and included one tag returned form coastal waters. The Pacific cod fishery is more widespread than when last studied, with sport efforts considerably enlarged.

Keywords: Northwest Straits//straits//nearshore//fish//northwest
Abstract: This report presents the set of action plans the Puget Sound/Georgia Basin International Task Force finalized in response to the 1994 Marine Science Panel recommendations. The Task Force divided into Work Groups. This is the report form the Protection of Marine Plants and Animals Work Group. In response to Immediate Policy Concerns, the Work Group proposed the following actions: integrate and coordinate governing bodies and agencies responsible for the health of the Strait of Georgia ecosystem; create MPAs; prevent loss of nearshore and estuarine habitat; preserve biodiversity; develop new management methods; involve the public; establish a code of conduct on the environment; control pollution and toxic discharges into the Strait of Georgia; assess current policies and management activities in the Strait of Georgia, and take global warming seriously. In response to the loss of foreshore and estuarine areas, they identified the need to take action to: not divide management at the tideline; reduce urban and industrial pollution; prevent introduction of exotic species; exchange information; improve assessment of marine mammal abundance; preserve juvenile salmon rearing capacity; establish an ongoing program to assess the health of all species in the Strait of Georgia, and communicate scientific and government information to the public.
A state of the strait is presented along with a series of papers on creating a sustainable future, share marine waters, fisheries sustainability, and contaminants in the Strait of Georgia and elsewhere. A series of papers and studies are summarized in this report.

Keywords: nearshore//vegetation//Puget Sound//straits
Abstract: Nearshore habitat degradation and loss are recognized to be major threats to the health of Puget Sound (British Columbia/Washington Marine Science Panel, 1994). Inventory data is needed to characterize the quantity, location, and quality of habitats, and to guide land use planning. Information on trends in habitat health is needed to identify the habitat features and functions that are most at risk, and to relate these changes to the state of the Puget Sound ecosystem. The Nearshore Habitat component of the Puget Sound Ambient Monitoring Program (PSAMP) has the dual goals of inventorying nearshore habitat and monitoring trends in health. For the purpose of the monitoring program, nearshore habitat includes the physical and biotic components of intertidal and shallow subtidal areas. Monitoring habitat is a challenge due to the size and complexity of the study area, which includes approximately 2,400 miles of shoreline east of Cape Flattery, and encompasses a wide range of habitats, from vertical rocky shores to wide, protected mudflats. Human activities range from intensive, in the highly industrial urban embayments, to relatively minor in the least developed areas.

Keywords: marine protected areas//MPA
Abstract: Designation of marine protected areas (MPAs) is increasing as humans seek to combat over-exploitation of marine resources and preserve the integrity of the ocean's unique biodiversity. At present, there are over 1300 MPAs. The primary legal responsibility for the designation of MPAs falls to individual countries, but protection of the marine environment at large scales is also critical because ocean circulation does not honor legal boundaries and often exceeds the influence of any one nation or group of nations. There are many reasons for establishing MPAs. The papers surveyed principally referred to scientific, economic, cultural, and ethical factors. Two approaches predominated: fisheries management and habitat protection. Although the major threat to terrestrial systems is habitat loss, the major threats to the world's oceans are fisheries overexploitation, coastal development, and chemical and biological pollution. MPAs may provide conservation of formerly exploited species as well as benefits to the fishery through leakage of 'surplus' adults (spillover) and larvae (larval replenishment) across reserve boundaries. Higher order effects, such as changes in species richness or changes in community structure and function, have only been superficially explored. Because many MPAs are along coastlines, within shipping lanes, and near human centers of activity, the chance of chemical and biological pollution is high. Use of MPAs to combat development and pollution is not appropriate, because MPAs do not have functional boundaries. The ocean is a living matrix carrying organisms as well as particles and therefore even relatively environmentally sensitive uses of coastal ecosystems can degrade ecosystem structure and function via increasing service demands (e.g. nutrient and toxics transformation) and visitation. Whether an MPA is effective is a function of the initial objectives.

Abstract: This report presents commercial tract densities and average weights. Biomass estimate calculations are presented and a model for an age-based equilibrium yield to predict long-term consequences of various harvest rates, using estimated geoduck life history parameters. The model predicts yield and spawning biomass per recruit over a range of fishing mortality rates. A strategy is recommended as a risk-averse policy for geoducks.

Abstract: Nearshore habitat degradation and loss are recognized to be major threats to the health of Puget Sound (British Columbia/Washington Marine Science Panel, 1994). Inventory data is needed to characterize the quantity, location, and quality of habitats, and to guide land use planning. Information on trends in habitat health are needed to identify the habitat features and functions that are most at risk, and to relate these changes to the state of the Puget Sound ecosystem.
The Nearshore Habitat component of the Puget Sound Ambient Monitoring Program (PSAMP) is responsible for inventorying nearshore habitat and monitoring trends in health. For the purpose of the monitoring program, nearshore habitat includes the physical and biotic components of intertidal and shallow subtidal areas. Monitoring habitat is a challenge due to the size and complexity of the study area, which includes approximately 2,400 miles of shoreline east of Cape Flattery, and encompasses a wide range of habitats, from vertical rocky shores to wide, protected mudflats. Human activities range from intensive in the highly industrial urban embayments to relatively minor in the least developed areas.
The Nearshore Habitat Program inventories nearshore vegetation through the collection and classification of multispectral sensor collected shoreline data field surveys in conjunction with photo interpretation. At current funding levels, sound-wide mapping will be completed within 15-20 years. A PSAMP review in 1995 recommended examining alternative methods to map resources soundwide in less than five years (Shen, 1995). Additionally, it recommended initiating a program to monitor trends in nearshore habitat health. This paper responds to the recommendations. It reviews user needs, how current systems fulfill user needs, and how inventory methods are being changed in response. It then reviews results of research which testing the feasibility of using a linked geophysical mapping and biologic sampling model for inventory and monitoring known as SCALE (Shoreline Classification and Landscape Extrapolation).

Abstract: Research on eleven artificial reefs in Puget Sound, Washington examined the relative importance of reef-produced prey items to recreationally important reef fish species assemblages. The colonization of potential prey items, and fish species assemblages to ten artificial reefs were examined for the reefs first two to five years, and observations were conducted on an eleventh reef during its forty-ninth productive year.

Keywords: rockfish//juvenile rockfish//rockfish recruitment//Puget Sound//San Juan Islands
Abstract: Habitat pathways and temporal and spatial parameters of substrate- associated recruitment have never been reported for juvenile quillback rockfish (S.maliger) in any ecosystem, and have never been described for juvenile copper (S. caurinus) and splitnose (S. diploproa) rockfish in Washington waters. In 1991-1994, juvenile quillback rockfish recruited only during July-August each cohort-year, correcting biannual recruitment errors in the literature for Puget Sound; first recruitment was apparently to offshore benthic habitats, with subsequent migrations to nearshore benthic macrophytes. Copper rockfish recruited during July-September each cohort-year; first recruitment was to surface and shallow water macrophytes attached to benthic substrates, with subsequent migrations to benthic macrophytes. During November-January, juvenile quillback and copper rockfish in natural macrophyte habitats migrated offshore associated with benthic drift macrophytes; juveniles in artificial and natural reef habitats migrated to deeper water associated with crevices in the substrates. Juvenile splitnose rockfish recruited during June-August each cohort-year; first recruitment was to surface drift macrophyte and seagrass habitats, which were vacated by December. Apparently co-occurring pelagic juvenile copper and splitnose rockfish selectively recruited to attached and detached vegetation habitats respectively.
Development of internal micro-tagging procedures for juvenile Sebastes enabled the first estimation of instantaneous natural loss rate (mortality and emigration) for this genus, without non-immigration assumptions. The estimate of Z258d=0. .0106 for quillback rockfish on an artificial reef recruitment habitat was lower than for a coastal pelagic species, the only other estimate for juveniles Sebastes. Nearshore artificial reef substrate manipulations functioned as juvenile rockfish recruitment habitats, providing preferred nursery and refuge habitats and enhancing local recruitment. Efficacies of artificial reef recruitment habitats located adjacent to, and isolated from, established reefs, were affected by variability in levels of juvenile rockfish recruitment, biogenic habitat parameters, and ecological maturity of the substrates. Micro-tagged juvenile rockfishes remained on artificial reef recruitment habitats during the cohort-year contrasting emigrations form natural macrophyte habitats during the cohort-year contrasting emigrations from natural macrophyte habitats. Increased densities of juvenile rockfish on artificial reef recruitment habitats late in the cohort-year indicated emigrations form natural habitats. Juvenile rockfish had average daily growth rates of 0.11-0.13 mm total length in both natural and artificial reef recruitment habitats.

Keywords: marine mammals//contaminants//water quality//human impacts
Abstract: This paper reviews principal studies conducted on contaminants in Puget Sound marine mammals and examines the patterns in concentrations of chlorinated hydrocarbons among species, across locations, and over time. Harbor Seals: PCB concentrations in blubber were found to be 50 to 100 times higher than the concentration in their prey reflecting the high proportion of contaminants they were absorbing from their prey and their limited ability to excrete or metabolize such compounds. Concentrations of PCBs and DDT were significantly higher in pups collected in southern Puget Sound than those from the Strait of Juan de Fuca. However concentrations of metals and trace elements showed no significant difference by site. Lead and silver were significantly higher in seals from the Strait of Juan de Fuca than from southern Puget Sound. Killer Whales: Concentrations of PCBs in blubber ranged form 0.9 to 250 ppm and total DDTs from 1.7 to 250 ppm and total DDTs from 1.7 to 640ppm. Spatial and temporal trends were not apparent. Unlike harbor seals, levels of DDT in killer whales were higher than PCBs. This was interpreted as indicating these animals were found to either primarily feeding outside of the greater Puget Sound region, a region predominating in PCBs, or their prey came from outside this region. For the Harbor porpoise, distinct differences in concentrations of contaminants were found among regions with a consistent increase in DDT concentrations along the coast of the Southern California Bight. PCBs in blubber ranged from under 1 ppm in an animal recovered on the Washington coast to 55 ppm in an animal from southern Puget Sound.Gray Whales: Concentrations of chlorinated hydrocarbons were low, PCBs in blubber ranged from 0.01 to 3 ppm. No significant differences were found by region. Concentrations of PCB's and DDT were lowest in minke whales and pygmy sperm whales. Much higher concentrations of PCBs and DDT were found in Dall's porpoise and river otters.
These studies reveal important patterns. The impacts of contaminants to harbor seals and killer whales demonstrate these two species to have the highest exposure to contaminants. Monitoring of contaminant trends and patterns in harbor seals are recommended due to existing data demonstrating clear regional and temporal patterns in contamination.
Calambokidis, J. and J. Quan. Gray whales in Washington State: Report on research in 1996. Final report to National Marine Mammal Laboratory, Seattle, WA. 1997.
Keywords: mammals//marine mammals//whales//gray whales
Abstract: This report summarizes research conducted by Cascadia Research in collaboration with the National Marine Mammal Laboratory during the 1996 field season. Cascadia Research has been conducting research on gray whales in Washington waters using photographic identification of individual animals since the mid-1980s (Calambokidis et al. 1994) with the goals of determining the number of whales using Washington waters, preferred areas for feeding, seasonality of use, and degree to which animals return year to year. Fifty boat surveys were conducted by biologists with Cascadia to observe gray whales between 15 March and 6 October 1996 totaling 243 hours of observation and 1,486 nmi of coverage. These included dedicated boats surveys conducted using a rigid-hulled inflatable and effort aboard whalewatch trips. The heaviest effort was in Grays Harbor, the western the Strait of Juan de Fuca, the northernWashington outer coast, and in the northern Puget Sound area. Data were also contributed by biologists at the National Marine Mammal Laboratory who provided identification photographs of gray whales made on an additional 13 days (between 13 June and 26 September) from surveys on the northern outer coast and the western Strait of Juan de Fuca. Gray whales were individually identified using photographs of the natural markings on the right and left sides. Comparisons of identified individuals were made to Cascadia’s catalog of over 100 gray whales seen in previous years off Washington as well as catalogs of identification photographs taken by collaborating researchers in British Columbia. In 1996, Cascadia Research and the Whale Museum received a total 112 gray whale sighting reports. were received by Cascadia Research and the Whale Museum in 1996. A total of 47 different gray whales were identified. A high proportion of the whales identified in three regions (northern Washington coast, Strait of Juan de Fuca, and southern Vancouver Island) were seen multiple times (73-79% by region) and had been identified in a previous year (64-82%). Gray whales identified near Grays Harbor early in the season were less likely to have been seen multiple times (52%) or a previous year (26%). Because most of these whales were identified in the migratory corridor during the migration (26-52%) when we would expect to be seeing migratory whales, this lower proportion of ‘resident’ whales was surprisingly high. Gray whales were frequently identified in multiple regions indicating movement patterns. Comparison of photographic catalogs with researchers working in British Columbia revealed that many of the whales that feed along the Washington coast through the summer range along the British Columbia coast to areas north of Vancouver Island. Conclusions of the research conducted through 1996 include: Gray whale use of southern and central Puget Sound is highly variable; few animals came into these waters in 1996. Previous research has shown whales that have been identified in these waters have never been resighted across years and have not been seen in other regions. A consistent group of individual gray whales had returned annually to the waters around Whidbey Island but the duration of their stay has become shorter. In 1996 we were not successful in finding these animals in this or any other region. A consistent group of individual whales feed each summer along the Washington outer coast and Strait of Juan de Fuca and range north past Vancouver Island. Some of these animals have returned over a 20-year period.

Keywords: marine mammals//Puget Sound
Abstract: Nine species of marine mammals commonly occupy the trans-boundary waters of British Columbia and Washington (BC/WA). Animals of all species move across this international border. Of the four pinniped species common to these waters, harbour seals are the most numerous and the only one that breeds in these waters. Approximately 30,000 harbour seals occur in the trans-boundary area. Harbour seal populations have increased at 10-15% per year. The numbers of California sea lions and elephant seals have also been increasing steadily although neither breeds in BC/WA waters. Steller sea lions, a species that is declining through most of its range, also occur in this region. Of the five cetacean species common to the waters, harbour and Dall's porpoise are the most abundant and number in the several thousands. Harbour porpoise numbers in some areas have declined since the 1940s, though little data are available to assess current trends in populations of these two species. Killer whales are the best studied marine mammal species in the area, with most of the individuals in the populations that use these waters identified photographically. Over 20,000 gray whales migrate past the entrance to the Strait of Juan de Fuca and some individuals spend prolonged periods feeding in the spring and summer in BC/WA waters. A small number of minke whales also return annually to these waters to feed during the spring, summer, and fall. Marine mammals are vulnerable to human activities in the BC/WA trans-boundary waters. High concentrations of contaminants, especially chlorinated hydrocarbons and some metals, have been identified in these animals. Highest concentrations of contaminants have been found in harbour seals (from southern Puget Sound) and killer whales. Determination of the impacts of these contaminants on marine mammals in these waters has been inconclusive, though in other areas contaminant exposure has caused reproductive failure and immunosuppression. Marine mammals are killed incidental to commercial fishing operations, particularly harbour porpoise, Dall's porpoise, and harbour seals. Information to assess human impacts on most marine mammals and to adequately evaluate their current status is extremely limited.
Calambokidis, J., G. H. Steiger, B. D. McLaughlin, and J. R. Evenson. Harbor seal haul-out habitat and the feasibility of shifting haul-out locations at Dosewallips State Park, Washington. Report to the Washington State Parks and Recreation Commission. Olympia, Washington. 1990.
Keywords: seals//marine mammals//Washington//Jefferson County
Abstract: High fecal coliform concentrations found at the Dosewallips River delta on the Hood Canal appear to originate from harbor seals that use the sloughs and marsh on the southern portion of the delta to haul out (Calambokidis et al. 1989, Calambokidis and McLaughlin 1988, DSHS 1988). In other areas in Puget Sound, harbor seals regularly haul out on human-made platforms, such as recreational floats and log booms (Calambokidis et al. 1978, 1985, Johnson and Jeffries 1977). Harbor seals used to haul-out on a log boom that existed at the north end of the Dosewallips River Delta through the mid 1970s. Because seal-related contamination is closely associated with haul-out locations, it may be possible to alter the affected areas by shifting the areas used by seals to haul out. This study examines the feasibility of shifting the seal haul-out habitat at Dosewallips delta from the salt marsh areas used currently to human-made structures that would be located just off the delta. We summarize relevant findings about the biology of harbor seals at this location, harbor seal haul-out requirements, what steps would need to be taken to shift the location of haul-out, and limitations of trying to conduct such a project. Counts made on 49 days from December 1989 to August 1990 at Dosewallips Delta ranged from 11 to 390 harbor seals and averaged 140 (n=49, s.d.=85). A number of factors were identified that were statistically associated with the variations in the number of seals counted at the Dosewallips Delta. These included time of day, temperature, and tide height and time to high tide. A major surprise from the results of this study was the significant decline in seal numbers at the Dosewallips River Delta in recent years. This trend data should be viewed with caution, especially because it does not cover some critical seasons. There were not significant increases or decreases in seal numbers observed at Duckabush River Delta or Quilcene Bay. At the Dosewallips River delta, harbor seals haul out along the three main southern sloughs and along or on logs along the river. We found significant seasonal and annual changes in the use of different portions of the Dosewallips River Delta. A trial float placed at Dosewallips River delta in May 1990 was showed no seal use until June 1990 and no regular use until late July. Females with pups were shown to occasionally haul-out on the float in late August towards the end of the pupping season. Exploratory behavior by seals in the water of the trial float was seen frequently. The amount of haul-out space required per seal was similar among locations and habitats and averaged about 2 m2/seal. The area used by seals at human-made habitats tended to be slightly larger than natural habitats, though this difference was small. The mean shoreline distance per seal (the distance of shoreline or water access for a group of seals) was generally under 1 m/seal at natural habitats and greater than
1 m/seal at human-made habitat. Human-made haul-out areas appear to provide some advantages over natural habitats, especially in their accessibility at all tides and their rapid access to deep water. The height above water for human-made structures used by seals, including log booms, floats, and a fish net pen, ranged from 12 to 54 cm with log booms lowest in the water. Float height above the water appeared to prevent newborn seal pups from getting out on the float for the first 1-2 weeks. It was calculated that a haul-out structure to accommodate the maximum number of seals observed to use the current haul-out area (470) would need to be 1,175 m2 using 2.5 m2 per seal. Shoreline space would need to be at least 1 m per seal or about 500 m total. This is less of a limiting factor since the haul-out area designs discussed below and human-made haul-out areas in general, easily meet this requirement. Human-made structures, log booms and floats, represent the best choices for alternate habitat at Dosewallips and a combination of both structures would provide the best alternative habitat for harbor seals. To allow segregation between groups we recommend use of multiple small structures as opposed to one or two large structures. The ideal log-boom structure consists of three logs secured together by crosspieces with total width of 1.5 m. For the float design, the most suitable and compact structure would be a series of open-celled concrete floats. A fairly compact 12 x 17m structure would be suitable for up to 60 harbor seals. A marked barrier around the structures would be necessary to keep boaters away from hauled seals and restrict them from using the structures for recreational purposes. The best location for an alternate haul-out site is along the steep slope marking the edge of the delta just north of the main river channel. Seals may not readily adapt to new structures.

Abstract: Aerial line-transect surveys were conducted during August 1996 primarily to estimate harbor and Dall’s porpoise abundance in five regions, encompassing US and Canadian waters of the Strait of Juan de Fuca, San Juan/Gulf Islands, and Strait of Georgia. A total of 6,263 km of on-transect effort were completed using a twin-engine high-wing aircraft flying at 90 knots and an altitude of 600 feet. Three observers searched for marine mammals through side bubble windows and a downward viewing port. Out of 1,505 groups sighted (3,340 animals) while on-effort, 1,074 were harbor seals, 311 were harbor porpoise, and 76 were Dall’s porpoise. We estimate abundance of harbor porpoise and Dall’s porpoise using line-transect methods. A re-analysis of aerial surveys conducted in 1991 was also completed to provide a comparable dataset using similar regional boundaries and analysis methods to look at temporal trends.

Keywords: porpoise//marine mammals
Abstract: Harbor porpoise abundance estimates have been made for Washington and Oregon using aerial and vessel surveys (Barlow 1988, Barlow et al. 1988, Calambokidis In Press, Calambokidis et al. 1991, 1992, Green et al. 1992 Turnock et al. In press). A major limitation of these estimates, however, has been that the fraction of animals missed on the survey line was not known. The primary objective of this study was to experimentally determine a correction factor for harbor porpoise missed during aerial surveys. Two methods were used to evaluate the correction factor for animals missed. The primary method for obtaining a correction factor was to measure the sighting success by aerial observers of specific harbor porpoise groups being tracked from land. Harbor porpoise groups in the study area were tracked from land prior to the aircraft passes. Secondarily, we gathered breath rate data on harbor porpoise groups to determine the proportion of time they are at the surface and likely to be seen by aerial observers. This was similar to the method used by Barlow et al. (1988) in devising a correction factor. The calibration experiment was conducted off the northwest side of Orcas Island in the San Juan Islands, Washington. Aerial surveys with a twin-engine aircraft were conducted in conjunction with land observations on 7 days between 3 August and 13 August 1992. A total of 547 transect lines were flown in 33 flight hours completing approximately 26 hours of transect surveys. Two teams, each consisting of 4-6 people made observations of harbor porpoise from land. Each team used an electronic theodolite interfaced with a computer data acquisition system. Radio contact between one of the aircraft personnel and the land teams was used to select aircraft transects that would include passing over a harbor porpoise group being tracked from land. To determine the proportion of harbor porpoise groups seen from the aircraft, several criteria were used to select the harbor porpoise groups that would be used for the calibration and to determine whether a group tracked from land was seen by the aerial observers. Harbor porpoise groups were included as a sample in the calibration only if: 1) they were seen from land within 4 minutes of the passage of the aircraft, and 2) were within 100m of the aircraft transect line. A harbor porpoise group being tracked from land was considered seen by the aerial observers if the position of the porpoise determined from land and air was less than 300m and if the number of porpoises in the group determined from the air was not more than twice or less than half the size determined from land. Using the parameters described above, 28 of 92 (30.4%) harbor porpoise groups within 100m of the transect line were seen by the aerial observers and 69.6% were missed. The point estimate for g(0) (the probability of sighting a group that was on the transect line) was 0.324 (SE=0.056). The sample size for this estimate was better than expected and provides a low enough variance that it will be able to be applied without greatly increasing the overall variance of abundance estimates. The correction factor for animals missed on the transect line was almost identical to that determined previously by Barlow et al. (1988) based on breath rate data of harbor porpoise. Seven different harbor porpoise groups whose surfacing were monitored spent an average of 36 sec (sd= 13.1) at or near the surface and 120 sec (sd=31.0) on longer dives of 30 sec or more. These values likely underestimate the time groups spend at the surface because some surfacings may have been missed. The proportion of harbor porpoise at the surface (potentially visible from the air) based on breath rates was slightly lower than the proportion seen in the calibration experiment. This may have been a result of our underestimating the time porpoise are at the surface (due to missing some surfacings). This also suggests that relatively few harbor porpoise on the transect line that were at the surface when the aircraft flew over were missed during the calibration experiment. The proportion of time we calculated harbor porpoise were at the surface from the breath rate data was similar to that reported by Barlow et al. (1988).

Keywords: marine mammals//Puget Sound//contaminants//seals
Abstract: Harbor seals (Phoca vitulina) are the most abundant marine mammal species in Washington State and occur throughout the marine waters including Puget Sound. Extremely high concentrations of some chlorinated hydrocarbon contaminants, especially PCBs, were found in Puget Sound harbor seals in the 1970s and 1980s. One of the longest-term datasets on trends in contaminants in the Puget Sound region comes from harbor seal studies. Harbor seal pups from Puget Sound have been collected or biopsied for testing concentrations of PCBs and DDT compounds at 4-5 year intervals from 1972 to 1997 at several Puget Sound sites including Gertrude Island in southern Gertrude Island in southern Puget Sound and Smith Island in the Strait of Juan de Fuca. Samples from harbor seals are ideally suited for trend analyses because they are highly contaminated, represent an integration of concentrations in a broad selection of prey in a region, and, with the utilization of non-emaciated pups, provide limited inter-sample variability allowing sensitive detection of changes over time. The most recent analyses were of both dead harbor seal neonates collected in 1996 and 1997 and biopsy samples of blubber from weaned harbor seal pups collected in 1993 and 1996 at Gertrude Island. We determined current levels of a broad range of chlorinated hydrocarbon contaminants in Puget Sound harbor seals including congener-specific concentrations of PCBs, DDTs and other pesticides, and the first analyses of polychlorinated dibenzo dioxins and furans (PCDDs and PCDFs). We tested both the most recent samples and re-tested some of the historical samples from 1984 and 1990 to provide more detailed data on historical contaminants. Harbor seals have proven to be an excellent indicator of environmental contamination at the upper level of the food chain with clear spatial and temporal differences detected. While concentrations of PCBs and DDT have declined dramatically since the 1970s, concentrations have stabilized since the mid-1980s with only slight declines since then. Even though concentrations have declined, harbor seals are clearly still at risk, with the current concentrations of PCBs and the TEQ in pups within the range identified as causing immunotoxicity in seals. Most of the TEQ came from PCBs rather than PCDDs or PCDFs. The plan is to continue monitoring trends in harbor seal contamination in Puget Sound at regular intervals and update trend data from other sites in Washington State.

Keywords: contamination//Puget Sound//birds//marine mammals
Abstract: The objective of this research was to determine whether detrimental effects possibly caused by toxic chemicals could be observed in Puget Sound marine mammals and marine birds. The study design was based on examination of a wide variety of indices of population and individual health and comparison of these indices from areas of suspected high contaminant levels (target areas) to those from areas of suspected low contaminant levels (reference areas) and to those reported by other researchers. Recent research conducted in Puget Sound has revealed high levels of contaminants in fish, marine mammals, and marine birds. High contaminant levels in Puget Sound have been correlated to abnormalities and disorders in fish. Researchers have also reported possible linkages between contaminants and disorders in marine mammals and marine birds in other parts of the world. Primary species considered here are harbor seal, Glaucous-winged Gull, Great Blue Heron, and Pigeon Guillemot; these species were chosen because they reside, feed, and breed in some of the most contaminated portions of Puget Sound. Three other mammal species (killer whale, harbor porpoise, and river otter) were chosen as secondary study species either because they seasonally occur in contaminated areas of Puget Sound or they were found through previous research to be experiencing problems that might be pollutant-related. Target areas were chosen that were as close as possible to the heavily contaminated Elliott and Commencement Bays. Reference areas used for different species included sites north of Puget Sound, in the Hood Canal, and in Grays Harbor and Willapa Bay on the Washington outer coast. Several biological parameters were examined to evaluate the evidence for pollutant-related problems. These parameters included population distribution, population trends, measures of reproductive success, mortality, causes of death, incidence of gross and histological pathology, and incidence of physical deformities or disorders seen in the population. To detect a broad range of possible effects, both general population health as well as incidence of individual disorders previously linked to contaminants were examined and measured. Study methods varied by species. Censuses were made from the ground, boats, and from small aircraft and provided population figures for several species. Reproductive rates were determined from censuses and for birds, by observing marked nests. Mortality and the incidence of reproductive disorders were determined from breeding area searches and censuses made during the breeding season. Gross pathology was determined from necropsies of animals found dead and for some species from collected individuals. Samples for histopathology, microbiology, blood parameters, and eggshell thickness were collected from appropriate species and examined by specialists for comparison between locations. Tissues for contaminant analysis were collected and archived, but not analyzed. We found a wide variety of disorders in some marine mammal and marine bird species. Some of these disorders followed patterns consistent with known patterns of contaminant concentrations in Puget Sound. Evidence for possible pollutant-related disorders is summarized. Overall, populations of the study species are doing very well, with the exception of the harbor porpoise and the killer whale; these two populations have declined in the Puget Sound area. For harbor porpoise the decline occurred prior to the 1970s and for killer whales the evidence of a decline is recent. Harbor seal numbers are generally increasing in all our study areas, however, an unusually high incidence of premature births and neonatal mortality was found at some sites. These disorders are similar to those that have been linked to effects of contaminants in pinnipeds from other parts of the world. The high incidence of these disorders seen in Puget Sound seals, however, was found not at sites with suspected high contaminant levels but, rather unexpectedly, at study sites with suspected low contaminant levels. The most likely explanation for these problems is disease agents in these populations compounded by the possibility that these areas are nearing carrying capacity for seal numbers. A significantly higher incidence of disorders and umbilical lesions found in contaminated areas reflects a pattern of impacts associated with contaminant presence. Puget Sound marine bird populations do not appear to be declining or experiencing major reproductive problems. Two of three primary study species (Glaucous-winged Gull and Great Blue Heron), however, did show significant eggshell thinning compared to pre-1947 measurements. In addition, Pigeon Guillemots had lower overall eggshell thickness than those reported for pre-1947, but the difference was not statistically significant. These findings suggest a possible persistent detrimental effect of the pesticide DDT (and its primary metabolite, DDE) as has been reported for a wide variety of bird species in other areas. We also found evidence of highly variable liver weights in gulls that may have been associated with contaminants. No conclusive statements regarding the association between contaminants and eggshell thinning or liver weights can be made until chemical analyses of archived tissues are conducted. Contaminant analysis of archived samples would greatly augment this study in several ways. This analysis is important in order to: verify assumptions about contaminant exposure of different populations; provide a better comparison with findings in other areas; allow correlation tests between disorders found in specific animals and their contaminant burdens, and describe trends in recent contaminant exposure of marine mammals and marine birds.

Abstract: Dead newborn harbor seals (Phoca vitulina) were collected from Smith Island in the Strait of Juan de Fuca and from Gertrude Island in southern Puget Sound. A variety of chemical contaminants were measured in different kinds of tissue from seven harbor seal pups from each location. Various tissues were also evaluated microscopically for histopathological abnormalities. Two methods for determining the concentrations of PCBs and DDE in blubber tissues were compared. Concentrations of PCBs, lead and silver were significantly higher in the seals from Gertrude Island than those from Smith Island. However, the concentrations of PCBs in seal pups from both locations have declined significantly since testing began in 1972.

Abstract: Overview of data collected from studies over the period of 1989 to 1993 on the effects of chemical contaminant exposure on juvenile chinook salmon in polluted urban Puget Sound estuaries. The data collected reveals increased exposure of juvenile chinook salmon to toxic chemicals in these estuaries. Juvenile salmon inhabiting contaminated urban estuaries displayed immune system alterations and impaired growth when compared to juveniles from hatcheries or non-urban estuaries. Juveniles from the Duwamish Waterway showed immunosuppression and increased disease susceptibility to Vibrio anguillarum. Studies during this period provide evidence of linkage between juvenile chinook salmon health and elevated contaminant levels in polluted estuaries.

Abstract: This reports on a baseline study to document the distribution, abundance, and biomass of nearshore fishes along the Strait of Juan de Fuca, to determine their food habits, and to identify the macroinvertebrates collected incidentally with the fish. A total of 93 species of fish was collected from 1976 to 1978. Trends in occurrence, abundance, and biomass for individual species were fairly consistent between 1976-77 and 1977-78. The predominant nearshore demersal fish species in beach seine collections were the Pacific staghorn sculpin, Eng. sole, and sand sole. The dominant neritic fish species in townet collections were the Pacific herring and longfin smelt. The predominant intertidal fish species were the northern clingfish, tidepool sculpin, and high cockscomb. Species richness generally increased from west to east in beach seines and townet collections while the opposite trend was observed in tidepool collections. Species richness and density was highest in summer and fall and lowest in winter. 53 of 55 common nearshore resident species preyed upon gammarid amphipods. Gammarids composed more than 50% of the total Index of Relative Important for 31 fish species and than 75% for 9 species. Calanoid copepods were the dominant prey of neritic fishes.

Abstract: The authors review techniques for estimating the abundance of migratory populations and develop a new technique based on catch-age data from geographic regions and their earlier technique, catch-age analysis with auxiliary information. Data requirements are catch-age data over several years, some auxiliary information, and migration rates among regions. The model, containing parameters for year-class abundance, age selectivity, full-recruitment fishing mortality, and catchability, is fitted to data with a nonlinear least squares algorithm. A measurement error model and a process error model are presented and favor the process error model because all model parameters can be jointly estimated. By application to data on Pacific halibut, Hippoglossus stenolepis, the process error model converges readily and produces estimates with no significant bias.

Abstract: Stresses on marine ecosystems due to changing global climate and the encroachment of human development are manifested in the Pacific Northwest by loss of habitat and the reduction or extinction of many important organisms. Studying the ecological functions of marine habitats and measuring the extent and rate of habitat loss is important to determining the health of Puget Sound. To monitor habitat changes in Puget Sound, there is a need to map shoreline types and inventory the marine biota for: 1) measuring change due to natural or human-caused perturbations; 2) mapping areas with key resources or potential for these, and 3) choosing sites for research and for monitoring programs. Our ability to detect changing the biota of the Sound requires that the information we gather about the biota has a sufficiently fine spatial scale of resolution, and that we take steps to minimize the inherent variability that exists in all ecological data sets. One way to do both is to take into account the geophysical features of the shorelines being mapped or studied as such features strongly affect biotic communities.

Keywords: rockfish//Puget Sound
Abstract: Summary of a study identifying nursery habitats for three demersal Puget Sound rockfish species. Recruitment was concentrated along the northwestern shoreline of central Puget Sound. Young-of-the-year (YOY) rockfish were found to use all three kelp, macroalgae, and eelgrass vegetated habitat types with kelp habitat supporting the highest densities. The vegetated habitats appeared to provide refuge for juveniles making the transition from pelagic to benthic habitats. The findings suggest that vegetated habitats may be necessary for replenishing and maintaining adult populations of copper, quillback, and brown rockfish. Recommendations include using vegetated habitats for juvenile rockfish as a habitat management. The study supports the use of vegetated habitats to be considered in habitat management and mitigation. Most recruitment of YOY rockfish in this study occurred in urbanized shorelines where habitat degradation and alteration were common. Such shoreline changes and habitat degradation may effect natural rockfish production. This study data is now incorporated into Washington Administrative Code (WAC).

Abstract: This report was commissioned by the Puget Sound Water Quality Authority through an agreement between the U.S. Environmental Protection Agency (EPA) and the Canadian Department of Fisheries and Oceans (DFO). Its purpose is to assist the Washington and British Columbia Working Groups on Minimizing the Introduction of Exotic Species in developing recommendations to the British Columbia Washington Environmental Cooperation Council. It assesses the status and management of NIS introductions into the shared marine waters of British Columbia and Washington. Pathways of NIS introduction are evaluated, and the management programs in place to reduce risks from these pathways are described. It is intended that from this report and from the work groups that will consider it, recommendations will emerge that address risk and management of NIS introductions, and needs for further information.
Pathways of NIS introduction to the shared marine waters include aquaculture activities; the aquarium trade; public aquaria; releases of NIS by individuals; commercial, military, and recreational marine vessels; research institutions; and seafood commodity distribution. Risk of NIS introduction from aquaculture is well defined, the industry is highly regulated, and active processes are underway for continuous review of aquaculture activities as they involve NIS. Risk of NIS introduction from aquarium activities and release of NIS by individuals is poorly defined, and only limited information is available to define the risks from research, seafood distribution, and marine recreational vessel activities. The relative risk associated with the large inoculation of marine NIS from ballast water discharges is assessed from shipping industry data and relevant scientific literature. Management of NIS in other selected states and countries is briefly reviewed.

Abstract: Bottom trawling is one of the most disruptive and widespread human-induced physical disturbances to seabed communities and has become a global environmental concern. We used a comparative approach to test the hypothesis that persistent otter trawling decreases bottom habitat complexity and biodiversity, increases the abundance of opportunistic species, and benefits prey important in the diet of some commercially valuable fish. We compared two similar and adjacent fishing areas at 180 m off central California in Monterey Bay National Marine Sanctuary: one inside the three-mile coastal zone of restricted fishing with light levels of trawling and one beyond the three-mile limit with high levels of trawling. Differences in fishing effort between the two areas were confirmed and quantified by means of data and tow number statistics from Pacific Fishery Management Council (PFMC) Trawl Logbook records. We used still photography, video footage, bottom grab samples, and experimental trawling to compare the physical and biological parameters of the two areas. The area with high levels of trawling had significantly more trawl tracks, exposed sediment, and shell fragments and significantly fewer rocks and mounds and less flocculent material than the lightly trawled area. Most invertebrate epifauna counted were significantly more abundant in the lightly trawled area. Densities of the polychaetes, Chloeia pinnata, as well as that of oligochaetes, ophiuroids, and nematodes were higher every year in the highly trawled area, and there were significantly fewer polychaete species every year in the highly trawled area. Content analysis of fish guts showed that C. pinnata was a dominant prey item for some of the commercially important flatfishes in both lightly and heavily trawled areas. Our study provides evidence that high levels of trawling can decrease bottom habitat complexity and biodiversity and enhance the abundance of opportunistic species and certain prey important in the diet of some commercially important fishes. This work also illustrates how constraints currently imposed on fisheries research by the near universal absence of true unfished control sites severely limit our ability to determine appropriate levels of harvest pressure for maintaining sustainable fisheries and marine biodiversity. Valid research in these areas will require marine reserves in which fishing effort and methods can be manipulated in collaborative studies involving fishers, researchers, and resource agencies.

Keywords: marine birds//Puget Sound
Abstract: This paper reports on a shorebird counts at 59 sites in the greater Puget Sound area, Hood Canal and the Strait of Juan de Fuca. Kilisut Harbor was the only site in eastern Jefferson County to have over 1,000 shorebirds. The high count at Kilisut was 1646 in 1992-93 counts and 796 in 1993-94. Sites with greater than 1,000 shorebirds are considered important for conservation and monitoring purposes. Sites with less than 5,000 shorebirds were found to support 27% of the winter population in both years of the study. Many disturbance factors threaten shorebirds and their winter environment. Most sites with over 1,000 birds occur in a cluster situated near major shipping channels, oil refineries and industrial centers. This makes such populations highly vulnerable to impacts of environmental pollution and habitat loss.

Abstract: A pilot study assessed the potential effects of pile driving activities on the behavior and distribution of schools of juvenile pink and chum salmon. Sites studied included the Everett Homeport (near the mouth of the Snohomish River), Elliott Bay Marina (Seattle), and the Kingston and Bremerton Ferry Terminals. School size, frequency of occurrence, species distribution, and general fish behaviors were measured at the sites where pile driving and fish presence coincided. Individual fish were sub-sampled for total length, weight, and stomach contents. On sampling days, tidal stage, weather, salinity, and the underwater acoustic environment were also measured.
Pile driving did not occur at the Kingston site, and juvenile Pacific salmon were not present at the Bremerton site when pile driving was in progress. Therefore the data form these sites do not provide direct information on the impacts of pile driving on juvenile salmonids. Very few fish were observed at the Elliott Bay site, with or with out pile driving.
The majority of results regarding the impacts of pile driving on juvenile salmonids ecology are form the Everett Homeport site. The following encapsulates the results: 1) within the range of salmonid hearing, the sound field generated by pile driving activities had a radius of at least 600 m.; 2) pile driving operations apparently affected the distributions and general behavior of fish schools about the site; 3) nearly twice as many fish schools were found on the construction side of the site on non-pile driving days compared to driving days; 4) fish schools were typically in water <1.5 m, within 2m from shore, and they were surface oriented. Fish school distances form shore did not change significantly as a result of pile driving. Average total length of fish did not increase significantly over the study period, suggesting fish were either transient and/or not growing. Stomach content analysis indicated that most fish were feeding, and while salinity and tidal stage probably affected the vertical distribution of fish in the water column, it did not appear to alter fish behavior or distribution about the construction site as measured in this study.

Keywords: Puget Sound/overwater structures/habitat impacts/eelgrass/impact assessment
Abstract: STUDY OBJECTIVES: Impact Assessment. Determine if small single-family residence docks cause a decline in eelgrass densities under and adjacent to piers and assess if the use of gratings mitigate the impacts. METHODS: Empirical: eelgrass density was measured under and adjacent to a selection of seven "single- family" dock sites in Puget Sound from Roche Harbor to South Hood Canal. Baseline measurements and one year of post-project monitoring were also taken for five sites to assess effectiveness of mitigating impacts with grating. OBSERVED DENSITY DECLINES: Six out of the seven sites selected to measure declines without mitigating construction methods demonstrated measurable declines and/or absence of eelgrass growing under the docks. The one site that did not show measurable impact appeared to have a mitigating aspect to its structure as the dock moved up and down and side to side with tidal fluctuations. Four of the five structures evaluated for alternative mitigating construction methods demonstrated eelgrass densities decline when compared to undisturbed reference areas. At the fifth structure site, eelgrass density increased but increased substantially less than it increased in the reference area. COMMENTS: Preliminary results support the hypothesis that shading is the major cause of eelgrass density loss. This is demonstrated by significant reductions in density under docks and diminished reductions under docks with grating used to mitigate shading impacts. Structure length, height over the bottom, design, orientation, and local environmental conditions (i.e. current patterns) may also play a role in the nature and extent of impact.

Keywords: nearshore//fish//Puget Sound//salmonids//salmon//rockfish// cod//lingcod//bottomfish
Abstract: Fishes occurring in the nearshore surface waters of northern Puget Sound, Washington were studied during 1974-1976 using a two-boat surface trawl (townet). Five sites, each representing a different habitat type were sampled in each of three geographic areas. Study objectives were to document the abundance, spatial and temporal distribution of fishes occurring in nearshore surface waters of northern Puget Sound. Nearshore surface waters were utilized as nursery and rearing areas by numerous fish species. While the townet was designed to sample larvae, larval fish were caught abundantly, primarily in spring. Mainly juvenile fish were found throughout the entire year in nearshore habitats. Few large fish were caught, perhaps because of avoidance. Of the 71 fish species captured, the 6 most abundant species comprised 98 percent of the total numerical catch. Twenty species were schooling whereas 51 were demersal; schooling species generally were more frequently occurring and more abundant than non-schooling species. Catches of most species were highly seasonal and indicated a lack of permanent resident species. Young-of-the-year Pacific herring were the dominant fish species occurring in nearshore surface waters. Herring catches were especially large at sites associated with protected eelgrass bays and in areas near known spawning grounds. Maximum catches of herring occurred during the spring and summer whereas minimum catches occurred in the fall and winter. Other abundant species included young-of-the-year Pacific sand lance, juvenile and adult threespine stickleback, larval to adult surf smelt, and larval to adult longfin smelt. While numerically not abundant, juvenile salmonids (mostly chinook salmon) occurred consistently in spring and summer primarily in the Cherry Point and Anacortes areas. The dominant nearshore pelagic species were present throughout the various nearshore habitats of northern Puget Sound with little evidence of distinct assemblages in different habitats. However, even though the dominant species exploit the entire nearshore spectrum of habitats, there were preferred habitats and areas.

Abstract: This synopsis lists the birds reported to prey on marine fishes off the Queen Charlotte Islands, British Columbia, and provides an abbreviated account of the prey with respect to their habitat, abundance, life history, commercial importance, and avian predators. In total, 50 avian predators were reported. All preyed on pelagic fishes; 14 preyed on demersal fishes; and 221 preyed on inshore fishes. Twelve species preyed upon all three groups. Seventy-eight different prey were reported -- 62 identified to species, six to genus, nine to family, and one to order. Pacific herring Clupea pallasi attracted the most avian predators (40 species), particularly during inshore spawning and early life history stages. In many cases, predation on inshore and demersal species was during their early life history stages, either as pelagic larvae or juveniles or as recently settled juveniles in shallow water.

Abstract: A Class II Inspection was documented at the Port Townsend Paper Company pulp and paper mill just south of Port Townsend, Washington between November 15-17 in 1993. Related sediment sampling was conducted December 15. The combined process water and sanitary discharges met all NPDES permit requirements. The sanitary effluent was also well within all permit requirements. All VOA and BNA compounds found were within applicable EPA water quality criteria. No pesticide/PCD compounds were found in the influent or effluent. Five priority pollutant metals were detected in the effluent. Copper was found in an estimated concentration of over four times Ecology water quality criteria. The fathead minnow chronic test and bivalve larvae test demonstrated sensitivity to the pulp mill effluent. No VOA compounds were detected in the sediment samples. All BNA compounds and metals detected were below Ecology Marine Sediment Quality Standards. No toxicity was found in the Microtox test. Amphipod test results found one sample equal to 25 percent toxicity.

Abstract: This report describes the methods we used to collect geoducks, age the shells and estimate growth and recruitment rates. A discussion of the methods is discussed. Most shells used for age and growth determinations were collected from unharvested geoduck beds form 1979-1982. All samples discussed in this report were taken in water depths of between 10 and 20 meters. Many locations throughout Puget Sound were sampled. From 1970 to 1987 samples were taken to estimate recruitment in harvested and unharvested geoduck beds in small plots extensively disturbed by a venturi suction dredge.
Healy, M. C. Juvenile Pacific salmon in estuaries: the life support system. In: Kennedy V.S. (ed.). Estuarine Comparisons. New York. Academic Press. 1982.
Keywords: salmon//Puget Sound//estuaries//fish
Abstract: Three species of Pacific salmon (chum Oncorhynchus keta, chinook Oncorhynchus tshawytscha and coho Oncorhynchus kisutch ), spend significant time rearing in estuaries following their seaward migration. Chum are abundant in estuaries for two months in early spring, coho for two months in late spring, and chinook throughout the spring, summer, and autumn. The specific habitats occupied by each species vary with the size of the fish, the stage of the tide, and the time of year. Tidal creeks through marshes, the junction of major and minor distributaries in the intertidal zone and the delta front are favored habitats. The diet of juvenile salmon in estuaries reflects a mixture of preference and availability, and the availability of food varies significantly between years and between estuaries. Major prey tend to be highly concentrated in the boundary layer at the mudwater interface, and many are detritus feeders, indicating that the food web leading to juvenile salmon is detritus based. The value of an estuary as rearing habitat for juvenile salmon appears to be influenced by delta configuration and by the efficiency with which allochthonous organic carbon is trapped.

Abstract: This paper describes the development of an integrated strategy for the establishment of a comprehensive MPA system along the Pacific Coast of Canada. Parks Canada, BC Parks, the Dept. of Fisheries and Oceans, the BC Land-Use Coordination Office, Environment Canada and BC Ministry of Agriculture, Fisheries and Food have collaboratively developed a draft proposal describing the following: a common vision and definition of MPA's; common goals and objectives for an MPA system; guiding principles for the establishment and management of MPA's; possible management regimes and designations of MPA's, and a proposed process for the identification, evaluation, establishment and management of MPA's. A series of stakeholder forums have been held in three coastal communities to discuss these proposals with a wide variety of stakeholders. Implementation of the strategy will be linked with coastal area management planning.

Keywords: rocky reef//mitigation//habitat//fish
Abstract: An artificial reef was constructed on a featureless sand bottom as mitigation for the man-caused loss of rocky-type subtidal habitat in Elliott Bay, Puget Sound, Washington from a shoreline development (fill) project. Using a list of indicator biota developed for this region, it was predicted the mitigation reef would develop a greater number of economically important fish species and greater diversities of sessile and epibenthic biota assemblages than the development site. The design of a 1:2 ratio of reef material: sand bottom accommodated the trophic level relationships normally occurring for fishes feeding from reef structures and surrounding natural habitats. The mitigation reef met the predicted development during the reef's first 8 months of submergence.

Abstract: During Wateryear 1991 (October 1990 through September 1991), the Washington State Department of Ecology monitored water quality monthly at 28 stations in Puget Sound, four stations in Grays Harbor, and five stations in Willapa Bay. Of the 28 stations in Puget Sound, 23 sites showed dissolved oxygen concentrations below the water quality standards for marine waters one or more times, and 11 exceeded fecal coliform counts of 14 organisms/100 milliliters (mL) one or more times. Nutrient depletion was observed at 20 Puget Sound stations. Of the nine coastal stations, none violated dissolved oxygen standards, and four exceeded fecal coliform counts of 14 organisms/100 mL one or more times. Nutrient depletion was only observed at the Willapa Bay stations. Stations that did not experience nutrient depletion as defined by this report, were well mixed and lacked observable ongoing density stratification. At several Puget Sound stations, chlorophyll a concentrations were inversely proportional to nutrient concentrations, with maximum chlorophyll a concentrations and minimum nutrient concentrations observed simultaneously. Chlorophyll a concentrations were highest during the spring and summer months and lowest during late fall and winter months for Puget Sound stations. The coastal stations exhibited two chlorophyll a peaks, one during mid-summer and again in midfall. To assess the quality of the marine water column data, a detailed quality assurance assessment was conducted on the Wateryear 1991 (WY 1991) results. Ninety-four percent of the nitrite results were below detection limits. Discontinuing dissolved nitrite analysis until lower detection limits can be achieved was recommended. The quality assurance assessment also revealed that the fecal coliform bacteria results did not achieve precision objectives in either the field or laboratory replication. Procedures for future collection and analysis of fecal coliform bacteria should be amended to improve the quality of these data. In general, to improve temporal and spatial coverage for shorter term and episodic water quality events not caught by the monthly sampling component of the program, continued monitoring efforts should include a seasonal monitoring component. Sites showing signs of nutrient depletion and/or conditions that promote biological activity (stratification) should be priority candidates for seasonal monitoring.

Abstract: This report was prepared to support a parallel effort of nearshore habitat mapping and characterization titled Critical Nearshore Habitats, Tala Point to Kala Point, Jefferson County, by Ron Hirschi (1999). Much of the field observations for the two studies were conducted simultaneously by boat or on foot. Similarly, the focus and conclusions of the two studies were reached cooperatively. Therefore, each report should be used in conjunction with the other, as the intent was for each of the two elements to augment each other and provide mapped features representing the conclusions of the multi-disciplinary effort.
Accompanying this report are three original USGS 71/2 minute quadrangles (Port Ludlow, Nordland, Port Townsend, South) that contain mapped critical shoreline areas discussed in the text. Portions of these three maps are reproduced within the report for convenience. Information on geology and coastal processes were compiled from existing published reports and maps as referenced, along with observations made while visiting the entire shore of the study area in the winter of 1998-99 and earlier. The study area for the project ran form Tala Point (east of Port Ludlow Bay) in the south end to Kala Point (in Port Townsend Bay) in the north.

Keywords: cod//Pacific cod//Port Townsend//Puget Sound//bottomfish// groundfish//fish//Jefferson County
Abstract: Pacific cod migrate into the waters of Port Townsend Bay during the winter. An intense commercial set net and trawl fishery is directed at these Pacific Cod spawning aggregations. Life history parameters estimated during this study were consistent with those expected from a fast growing, early-maturing stock close to the southern limit of its range. Growth analysis of length frequency data and tag returns provided length-at-age estimates of 27.0, 43.5, 55.5 and 64.2 cm at ages of 1,2,3, and 4 years. Population estimates indicated that there were about 14,000 fish in the bay when the fishery began. The population increased rapidly and reached a peak of more than 1100,000 fish within 10 days of the start of the fishery. Peak abundances were observed for approx. 1 week and then a gradual decline in the population size was observed. Seven weeks after the fishery began, population size was estimated to be 35,000 fish. Between 15-20 percent of the cod present in the bay on a given day emigrated or were caught during the subsequent 24 hours. Between 359,000 and 510,000 fish migrated into the bay during the season and 24 to 34 percent were harvested. The set net gar was more effective in harvesting larger fish, especially females.

Abstract: Egg, larval, juvenile, and adult stages of the Pacific cod (Gadus macrocephalus) were sampled form the waters of Port Townsend Bay to provide information concerning the life history and fisheries biology of this species. Trawl sampling, carried out in January and February 1977, provided material for the determination of basic statistics, age structure, stomach contents, and fecundity. The trawl-caught fish were found to be fast growing, early maturing, and with short lifespans. Estimated fecundity at length was greater than published values for populations from more northern waters. Preferred food items were shrimp and small fish. Icthyoplankton sampling was carried out on seven occasions from February through June 1977. Gadoid (cod family) larvae were identified form many of the samples but poor documentation of the early life history of Pacific cod precluded positive identification of these gadoid larvae to species. It was suggested that gadoid larvae observed in late April were probably Pacific cod, based on spawning time and published rates of development. Attempts to rear Pacific cod eggs and larvae were not successful but the experiments did confirm reports that the eggs are demersal. Diving operations failed to encounter spawning adults or eggs. Eggs were not detected from a series of bottom grab samples. Juvenile Pacific cod were identified from trynet samples taken in northern Kilisut Harbor and along the northwest shore if Indian Island in mid-June 1977.

Abstract: This report presents the results of an investigation in the occurrence of severe liver disease and 100% mortality observed in Sea Farm Washington's pen-reared Atlantic salmon in Port Townsend Bay in the summers of 1986 and 1987. A long-term bioassay of Atlantic salmon using mill effluence indicated that the pulp mill was not the likely source of the presumed toxicant. The disease has also occurred at several net-pen sites in BC but does not appear to be associated with chemical contamination. It was suggested that the disease could be caused by a natural toxin, possibly an algal toxin, this hypothesis requires further testing. Chemical analysis of affected liver and muscle tissues, sediments, effluents, and the water column in separate but coordinated studies did not identify toxicants of likely significance. Such liver disease in at least three salmonid species at several sites in the Pacific Northwest identify the conditions as a significant limiting factor to successful net-pen culture in particular Pacific Northwest locations. Coho net-pen operations in Port Townsend Bay did not appear to be affected, neither were non-salmonid fishes such as surfperch and English sole. Small chinook were also found to be affected.

Abstract: This report presents an examination of nongame marine invertebrates (NGMI) situation for effective conservation and management. This report overviews NGMI in Washington waters, sources of losses, species status, and conservation guidance. Although the quality of Puget Sound may be improving through agency efforts and a concerned public, individual invertebrate species and communities are disappearing or are threatened over large part so their ranges. Direct sources of loss include: collecting for teaching by schools, collecting for schools by commercial supply companies, collection for research or bioassays by scientists, collecting for public aquarium, harvesting for subsistence by citizens, collecting for bait to catch other species and collecting for souvenirs. Indirect sources of loss include: derelict commercial fishing gear, especially gill and seine nets, sport and commercial harvesting, water and sediment quality pollution, commercial developments with activities such as dredging, pile driving and log rafting, walking and vehicle driving in the intertidal.

Keywords: Marine protected areas
Abstract: Canada does not have a national policy for the management of the coastal environment. Attempts to create and implement a policy have been futile due to the lack of public pressure and political will. Increasing public interest and concern in the marine environment can help motivate the political will. Public requests for increased marine protection has been successful in various states in the US and has become an effective tool in BC. The establishment of Whtyecliff Park in West Vancouver as a No-Take marine protected area was the direct result of a community initiative combined with academic and legal advisers. The establishment of no-take MPA's play a crucial role in developing a coastal management policy. Establishing a network of public initiatives will increase public awareness of the ocean as well as motivate the government to take action towards creating a national Coastal Zone Management Policy.

Data was collected annually at eighty-six stations throughout Puget Sound, Hood Canal, Strait of Georgia, and Strait of Juan de Fuca. Stations included Port Townsend Bay, southwest shore of Indian Island, and Discovery Bay. Target chemicals included antimony, arsenic, cadmuim, lead, selenium, silver, thallium beryllium, chromium, copper, nickel, zinc, mercury, aluminum, barium, calcium, cobalt, iron, magnesium, manganese, potassium, sodium, and vanadium. These include aromatic and chlorinated aromatic compounds, ketons, ethers, esters and carbon disqulfide and semivolatile organics, phenols chlorinated and nitro-substituted phenols, resin acids and low molecular weight polycyclic and chlorinated and aromatic hydrocarbons were amongst the contaminants identified and measured. Port Townsend was listed as one of ten stations having contaminated concentrations above state standards in any one year, which in the case of Port Townsend was 1989 only. Port Townsend also showed the presence of arsenic and nickel. Nickel was present in all years except 1995. Discovery Bay showed arsenic in 1994 only. These are the levels at which adverse biological effects are expected to occur. This was due to a high concentration of the resin bis(2-ethylhexyl)phthalate and dehydroabietic acid.

Abstract: Reports baseline data on contaminated and uncontaminated stations and evaluates condition of benthic macro-invertebrates in relation to toxic chemicals in sediments throughout Puget Sound, Hood Canal, and the Straits of Georgia and Juan de Fuca between 1989-1993. Stations included Port Townsend Bay, southwest shore of Indian Island, and Discovery Bay. Multivariate analysis techniques shoed that infaunal assemblages in Puget sound are primarily related to sediment composition and water depth, and secondarily to geographical location. This study represents the first system-wide effort to characterize benthic assemblages in the Puget Sound region.

Abstract: As a component of a three-year cooperative effort of the Washington State Department of Ecology and the National Oceanic and Atmospheric Administration, sediments from 100 locations in northern Puget Sound were tested to determine their relative quality. The purpose of this survey was to determine the quality of sediments in terms of the severity, spatial patterns, and spatial extent of chemical contamination, toxicity, and alterations to benthic infauna. The survey area encompassed the region from Port Gardner Bay north to the US/Canada border, excluding the San Juan Islands. Surficial sediments were tested and analyzed from each of the 100 locations. Data from the chemical analyses indicated that toxicologically significant contamination was restricted in scope to a relatively small portion of the region. The spatial extent of relatively severe contamination varied considerably among chemicals. However, less than 2% of the area was considered "contaminated" for most substances. Sediments from several sampling locations within Everett Harbor often had the highest chemical concentrations. In addition, samples from some stations in Bellingham Bay and other locations scattered throughout the study area had elevated concentrations of some substances. Data from four kinds of toxicity tests indicated a similar pattern: the degree of toxicity was highest in samples from Everett Harbor followed by those from other locations scattered within the survey region. The spatial extent of significant toxicity ranged from 0% to 5% among the toxicity tests. Wide ranges in several numerical indices of benthic infaunal structure indicated good correspondence with tests of toxicity and the concentrations of numerous chemical substances. That is, there was evidence of altered benthic populations in some areas nearest urban centers. Chemical contamination and toxicity of sediments were less severe in northern Puget Sound than in many other estuarine areas studied in the U.S. by NOAA. Results from similar analyses of samples from the central Puget Sound (sampled in 1998) and southern Puget Sound (sampled in 1999) will be compiled with the data from northern Puget Sound, to provide a broad-scale evaluation and quantification of the spatial scales and patterns in sediment quality throughout the entire region.

Abstract: This is a multidisciplinary working group organized through NCEAS working to make a significant contribution to our current understanding of marine reserves. This group is working towards the development of a theoretical basis for the design and establishment of marine reserves. Although there has been an increase in the number of marine reserves designated to manage marine resources, they do not believe that a concomitant increase in the understanding of marine reserve theory has occurred. As a result, reserve designs have often relied heavily on theory formulated for terrestrial ecosystems or on no theory at all. Recent research on open ecosystems suggests that marine reserves designed using these principles are likely to be ineffective at protecting marine communities over the long term. This fact, along with constantly increasing human pressure on marine ecosystems, indicates that a theory of reserve design specific to marine ecosystems is urgently needed.

Keywords: marine birds//Puget Sound//straits//northwest straits
Abstract: Systematic inventories of bird populations in British Columbia and Washington have emphasized numbers and productivity of breeding colonies and over-wintering populations utilizing various marine habitats. Wintering populations of birds tend to be much larger than the summer breeding populations. Species diversity is also greater during winter due to an influx of waterfowl and marine birds. Birds are at risk in the marine environment due to commercial fisheries, oil and hazardous materials spills, human disturbance, habitat loss, degradation of water quality, and contaminants from point and non-point sources. Indicator species should be selected that are most vulnerable and represent the various niches in the marine ecosystem.

Abstract: Hundreds of toxic chemicals occur in marine environments, and their potential for inducing; biological effects are of scientific interest. Because sediments are sinks for most chemicals, the transfer; of chemicals from sediments to organisms and subsequent transmission through food chains are; especially important. Organic xenobiotics in sediments are readily transferred to marine organisms. Some xenobiotics are metabolically labile, whereas others are essentially resistant to metabolism. The metabolically labile aromatic hydrocarbons, for example are extensively transformed in the livers of fish and the hepatopancreas of crabs. Substantial metabolism in fish markedly reduces the potential for food-chain transfer of aromatic hydrocarbons. However, little is known about the transfer of the metabolites. Metabolically resistant compounds have a high potential for accumulating in marine birds, mammals and humans. The biological transport of sediment-associated metals have not received much attention. Field studies indicate that most metals are not extensively bioconcentrated in marine fish. However, they are bioconcentrated in certain invertebrates such as molluscs.

Abstract: This report presents available information on important habitat associations for ten recreationally-utilized marine fishes in Puget Sound: copper rockfish, quillback rockfish, brown rockfish, Pacific cod, striped and pile surfperches, walleye pollock, lingcod, kelp greenling, and cabezon. Information was gathered on general species information to include reproductive habits, habitat associations, movement patterns, and food habits. Graduate theses, technical reports, baseline surveys and published literature were evaluated with an emphasis on Washington and supplemented by information form Canada, Oregon, Alaska, and California. Important habitat associations for young and spawning fishes were identified as an area needing further work.

Keywords: rockfish//bottomfish//groundfish//fish//Puget Sound
Abstract: Seasonal habitat use of young-of-the-year (YOY), subadult, and adult rockfishes (Sebastes caurinus, S. maliger, and S. auriculatus) were compared for four habitat types: high-relief rocky reefs, low-relief rocky reefs, high-relief artificial reefs, and sand/eelgrass. Diving surveys conducted December 1986 through October 1988 on two representative sites of each habitat type revealed significant seasonal changes in rockfish densities and habitat use. YOY recruitment varied between the two survey years: YOY were observed on all habitat types in the summer and fall of 1987, whereas they were observed at only one site (artificial reef) in a similar time period of 1988. High-relief rocky reefs had the most consistent densities of the three rockfish species with most fish>200mmTL. Adult and YOY copper, quillback, and brown rockfishes were observed on the low-relief rocky reefs primarily in the summer months coincident with summer algal growth; when the kelp died back in the fall, most rockfishes left these reefs. The highest densities of rockfishes, primarily 80-200 mm quillback rockfish (up to 420/90-m3 transect) and large copper rockfish (up to 56.3/transect), were observed on the artificial reefs. Here also, density fluctuations were dramatic; copper rockfish densities peaked in fall and winter and declined (to 0/transect) during the summer, and quillback rockfish densities also seasonally fluctuated. Sand/eelgrass areas were the least-utilized habitat type. Only during July and August were young-of-the-year and low densities of adult copper and brown rockfishes observed on one sand/eelgrass site. Although all four habitats were used, natural reefs may represent source habitats that are used by and maintain rockfishes on less productive sink (artificial reef) habitat. Thus, the recent use of artificial reefs as mitigation for the loss of natural reefs could have negative impacts on rockfish populations.

Abstract: Seasonal habitat use of young-of-the year, subadult, and adult rockfishes were compared for four habitat types: high-relief rocky reefs, low-relief rocky reefs, high-relief artificial reefs, and sand/eelgrass. Diving surveys conducted December 1987 through October 1988 on two representative sites of each habitat type revealed significant seasonal changes in rockfish densities and habitat use. Young of the year (YOY) recruitment varied between the two survey years: YOY were observed on all habitat types in the summer and fall of 1987, whereas they were observed at only one site (artificial reef) in a similar time period of 1988. High-relief rocky reefs had the most consistent densities of the three rockfish species, mostly fish>200 mm total length. Adult and YOY copper, quillback, and brown rockfishes were observed on the low relief rocky reefs primarily in the summer months coincident with summer algal growth; when the kelp died back in the fall, most rockfishes left these reefs. The highest densities of rockfishes, primarily 80-200 mm quillback rockfish (up to 420/90-m3 transect and large copper rockfish (up to 56.3/transect), were observed on the artificial reefs.

Abstract: A study was designed to test whether habitat association affects the movement patterns and habitat preferences of copper, quillback, and brown rockfishes. Resighting of tagged rockfishes (512 tagged rockfishes and 726 resightings) from July 1986 through June 1988 indicated that home ranges, movements form reefs, and tendency to return from experimental displacement (up to 8.0 km) were significantly different on the three habitat types compared. On high relief rocky reefs, rockfishes maintained small home ranges (most within 30m2), however, there were pronounced seasonal habitat references. In the summer, artificial reefs become less suitable; considerable off-reef movement occurred and rockfish did not return form displacements. In contrast, during fall and winter, rockfishes remained on artificial reefs and returned form displacements. On low relief rocky reefs, rockfishes maintained considerably larger home ranges (most within 400m2 and some up to 1500 m2).
Habitat use was affected by season. Rockfishes were only found in low relief reefs in the summer coincident with peak algal cover. Many rockfishes abandoned artificial reefs in the summer to move to low relief reefs and return to artificial reefs in the fall when kelp disappears on low relief reefs. Through habitat assessment, movements in response to habitat quality, and the ability to home, these rockfish maintain a flexible behavior for optimal habitat use.

Abstract: A study was conducted to assess the potential for uptake of toxic chemicals by down-stream migrant salmon in an urban estuary. Juvenile chinook salmon (Oncorhynchus tshawytscha ) were collected from the Duwamish Waterway (located in Seattle, Washington) and from the Nisqually River (a reference site). The mean concentrations of aromatic hydrocarbons and polychlorinated biphenyls (PCBs) in the stomach contents (food organisms) of salmon from the Duwamish Waterway were approximately 650 times and 4 times, respectively, higher than those in salmon from the Nisqually River. Similarly, the mean concentration of bile metabolites of aromatic compounds with fluorescence at benzo(a)pyrene wavelengths was 24 times higher in the urban salmon compared to the reference salmon, whereas the mean concentration of PCBs in liver of urban salmon were 3 times higher than that in reference salmon. The study clearly demonstrated that, during their residency in this urban estuary, juvenile chinook salmon bioaccumulate substantial levels of toxic chemicals.

Abstract: This reports on a study of policy alternatives for coastal erosion management. It provides Washington's Department of Ecology with a menu and critical evaluation of coastal erosions management policy alternatives appropriate to Puget Sound. It addresses existing policy and regulatory framework, current issues in coastal erosion management such as inadequate landowner involvement in evaluations; inefficient and complicated shoreline permit processes; limited use of soft solutions; reliance on hard solutions; frequent use of variances; lack of familiarity with risks, and inadequate environmental designations and a lack of guidance. Policy alternatives and tools are presented and evaluated.

Abstract: Reports on regional approaches that may be used to consider coastal erosion issues in the management of residential development and shoreline modification proposals. Research for this report results from a discussion paper, follow-up interviews and new case study summaries. A workshop was also held with decision makers who review shoreline development modification applications. The discussion paper was used extensively during the workshop for illustration of pros and cons of proposed regional policy approaches. This report describes: 1) command and control approaches to management of shoreline modification, 2) economic incentives and market-based solutions, 3) research monitoring data collection and education and outreach approaches, and 4) a summary of findings on approaches having the most merit in Puget Sound.

Abstract: Density, habitat use, and growth of intertidal 0+ age Dungeness crabs, Cancer magister, were examined at five northern Puget Sound (Washington USA) sites between June 1984 and September 1987. Sampling was conducted biweekly during settlement, from June to September, and approximately monthly or bimonthly thereafter. Northern Puget Sound Dungeness crab populations appear to be largely supported by recruitment form inland parental stocks, but a smaller proportion of recruits originated from coastal or oceanic stocks, as evidenced by earlier settlement and larger size of the first instar. Settlement of Dungeness crabs in inland waters typically peaked in August, and interannual variation in year-class strength at settlement (measured as intertidal density) was low relative to that reported or coastal crab populations. Spatial and interannual differences in settlement densities were mediated by high post-settlement morality, which varied inversely with habitat complexity. Seasonal densities were highest in mixed sand and gravel with an overstory of attached or drift macroalgae, intermediate in eelgrass (Zostera marina), and lowest on open sand. Post-settlement growth rates corresponded to seasonal water temperatures and were greatest for the coastal cohort that settled in May and June. This cohort was larger as first juvenile instars (7.2mm carapace width, CW) and grew rapidly at summer temperatures in excess of 15 degrees C to a size (>30 mm CW) that allowed emigration from intertidal to subtidal areas by September. The late summer cohort settled in August at 5.3 mm CW and soon after was subjected to decreasing autumn water temperatures. These crabs experienced little growth while overwintering in the intertidal, but growth rates increased in March. The crabs emigrated in April and May, approximately 10 mo. after settlement.

Abstract: We compared seabird and marine mammal entanglement rates and fish catch among two gear treatments (modifications) and a control throughout the day-night cycle during the 1995 Puget Sound sockeye and pink salmon fishery in Area 7 (San Juan Islands). The goal of this study was to test methods to eliminate or significantly reduce the incidental capture of seabirds in gillnet salmon fisheries without significantly reducing the fishing efficiency of the nets. The two gear modifications tested incorporate 10-inch mesh opaque netting at two depths in the upper quarter (50 Mesh) or upper eighth (20 Mesh) of a monofilament net and were compared to an unmodified monofilament control. The experimental nets were fished over a 24-hour period in a WDFW Test Fishery to determine if seabird entanglement and sockeye catch rates vary by time of day.

Abstract: We examined several strategies to reduce seabird bycatch, primarily of Common Murres (Uria aalge) and Rhinoceros Auklets (Cerorhinca monocerata), in a coastal salmon drift gillnet fishery in Puget Sound, Washington, U.S.A. Our goal was to significantly reduce seabird bycatch without a concomitant reduction in target catch or an increase in the bycatch of any other species. We compared fish catch and seabird bycatch in nets modified to include visual alerts (highly visible netting in the upper net) or acoustic alerts (pingers) to traditional monofilament nets set throughout the normal fishing hours over a 5-week fishing season. Catch and bycatch varied significantly as a function of gear. Relative to monofilament controls, murres responded to both visual and acoustic alerts. Auklets and sockeye salmon responded to deeper visual alerts only. Seabird abundance varied across multiple temporal scales: interannually, within fishing season, and over the day. At the interannual level, seabird entanglement was linked to regional abundance on the fishing grounds, a pattern that broke down at the local level. Within season, sockeye and murre abundance were negatively correlated, suggesting that if fishery openings were scheduled on peak abundance of the target species, seabird bycatch would be significantly reduced as a function of increased target fishing efficiency. Finally, both sockeye catch and auklet entanglement were found to be highest at dawn, whereas murre entanglement was high at both dawn and dusk. Our results identify three complementary tools to reduce seabird bycatch in the Puget Sound drift gillnet fishery: gear modifications, abundance-based fishery openings, and time-of-day restrictions for a possible reduction in seabird bycatch of up to 70-75% without a significant reduction in target fishing efficiency. Although these tools are based on local conditions and will thus vary among years and locations, all might be exportable to other coastal gillnet fisheries worldwide.

Abstract: Since July 1974, the Fisheries Research Institute's (FRI) Nearshore Fish Survey project has conducted an ecological survey of the nearshore fishes of north Puget Sound. The primary objective of this project was to document the seasonal occurrence, abundance, and distribution of the marine and estuarine fishes frequenting the waters adjacent to the shoreline. The survey was supported by the Washington State Department of Ecology (DOE) under the auspices of its Baseline Study Program, a comprehensive scientific and management research program designed to evaluate the biological and economic risk of oil and other pollution in northern Puget Sound. Emphasis was placed upon biota of the nearshore (less than 20 m depth) environs because pollutant effects, especially those induced during oil spills, have been found to be most pronounced there. Reliable measures of the composition, distribution, and abundance of nearshore fishes permit both (1) evaluations of the economic and ecologic importance of these regions and their associate fish fauna, and (2) assembly of a data base (i.e. "pre-pollution") for future reference against similarly documented samples after a pollution incident.
Fish data were collected monthly in representative intertidal and shallow subtidal habitats using beach seines and SCUBA transect observations. Quarterly trammel net sampling also supplemented the SCUBA observations. In addition, periodic surface tow net sampling was conducted adjacent to the sampling sites about San Juan Island and sites established by Western Washington State University along the eastern margin of the North Sound.
This report discusses the characteristics of the type-habitats sampled, the sampling techniques utilized, and the results of the 1974-195 collections and observations. Discussion of these results will include descriptions of the characteristic fish assemblages found in each of the type-habitats, the variations inherent in the sampling and due to seasonal changes in the assemblages, and a preliminary examination of the trophic relationships between certain important members of these assemblages and the habitats they characterize.

Abstract: The primary objective of this project was to analyze long-term trends in Puget Sound marine fishes based on a synthesis of the available data. A secondary objective was to establish baselines against which future fish monitoring efforts could be compared and evaluated. An additional benefit of the project was the identification of the collection methods used over the years, which can be used to help define standardized methods so that future investigations can be conducted in a compatible fashion.
Results: Peak occurrences of rare species occurred during usually cold (1918-1919, 1971-1975) for warm (1963,1965, 1983-1984) years, except for the peak in 1932-1935, which was a transition period form warm to cold temperatures. We think that routine monitoring of rare and unusual Puget Sound fish species yields important data, which to the best of our knowledge has not been collected since 19176. Although we do not claim that keeping current records of unusual occurrences of rare and exotic fishes is the most important Puget Sound monitoring tool, we think such monitoring can provide an early warning of environmental changes to Puget Sound.
In general, the analysis marine fish trends in Puget Sound based on relative frequency of occurrence data (form of CPUE) indicated that while research data did seem to measure real change in the relative occurrence of marine fishes in Puget Sound, there was no indication of a serious change in the relative occurrence of marine fishes in Puget Sound.. We noted that, by itself, data on commercial species is often not very useful for looking at long-term trends in fishes other than trends in the fishery itself, which may be impossible to separate from trends due to natural environmental changes (e.g. El Nino) and unnatural perturbations to the environment such as habitat destruction and toxic pollutants. We believe that a strong case can be made for monitoring as many non-economically important fishes in Puget sound as possible, ideally, assemblages of fishes occupying the major habitats in Puget sound should be monitored.
Long Term Trends at Specific Sites: Species richness at Golden Gardens beach in Seattle declined significantly from 1950-1972. A suggested reason for this decline was the habitat disturbance and change that occurred with the construction of the Shilshole breakwater in 1957-59. At Port Gardner in Everett, fish community measures (species richness and species diversity) were stable, but the CPUE of three common flatfish showed a decline from 2165-1987. Although we do not have a specific suggestion as to why this decline may have occurred, Port Gardner is well known to be located in an urban environment that has undergone continual alterations induced by humans.
We think these site-specific results further indicate the value of long-term monitoring using both community indices and individual species (both commercial and non-commercial "index" species) abundance measures of marine fishes in Puget Sound.

Abstract: The Marine Sciences Panel (194) recommended creation of marine protected areas as an important tool to reverse the declining population trends for a variety of resources in the Puget Sound-Georgia Basin. An international work group was established with both a British Columbia and a Washington branch. Efforts had been underway in British Columbia to establish marine protected areas and their work provided a valuable example to Washington staff. In January 1998, the Washington work group circulated a draft marine protected area strategy discussion paper. After the close in the comment period, this paper will be revised and submitted to the Puget Sound-Georgia Basin Task Force.
While the draft strategy was available for public comment, a Marine Protected Area Policy was elevated to the Dept. of Fish and Wildlife Commission. The policy calls for use of these areas as one of the working tools of the agency and it defines goals and principles for use regarding Marine Protected Areas. Adoption of this policy will be requested in June 1998. In January 1998, the Fish and Wildlife Commission adopted regulations creating the first "conservation areas' in Washington (Octopus Hole, Orchard Rocks and several beaches). These areas are closed to recreational harvest of all fish and wildlife. Restrictions on commercial harvest are being brought to the Commission for these areas.

Abstract: This report characterizes and discusses the nature of the institutional framework supporting MPA's in Puget Sound and the San Juan Islands. Basically, it 1) reviews MPA basic concepts, including definitions, management models and benefits; 2) classifies and profiles existing MPA's in Puget Sound; 3) identifies and reviews existing institutions and designation mechanisms responsible for the establishment and management of the current system of MPA's, and 4) summarizes and evaluates the overall system of MPA sites and institutional arrangements. In summary, the existing institutional structure is fragmented and complex with many organizations governing and managing resources. The Washington Department of Fish and Wildlife, Washington Department of National Resources, Department of Ecology and Washington Parks and Recreation Commission share responsibility for the management of a variety of types of marine protected areas and associated activities.

Abstract: English sole (Parophrys vetulus
) inhabiting polluted waterways and embayments of Puget Sound, Washington,
USA, are affected with a variety of multiple, co-occurring idiopathic hepatic
lesions, including unique degenerative conditions, putatively preneoplastic
foci of cellular alteration, and neoplasms. Results of a statistical analysis
of the patterns of co-occurrence of these lesions in wild English sole
are consistent with the concept that these lesions represent morphologically
identifiable steps forming a sequence of progression ultimately leading
to the development of hepatic neoplasms. The rationale for the hypothesis
that these lesions in wild English sole can be caused by exposure to certain
hepatoxic and hepatocarcinogenic xenobiotic compounds in the marine environment
is based on the demonstration of significant and consistent statistical
associations between levels of aromatic hydrocarbons in sediment and prevalences
of these idiopathic liver lesions. Idiopathic hepatic lesions have been
detected in white croaker (Genyonemus lineatus ) captured from contaminated
marine sites in the vicinity of Los Angeles, California.

Abstract: The report presents the findings

recovery of salmonid fishery stocks listed as endangered or threatened
species under the Endangered species Act. The working group found that
the presence of Calif. sea lions and Pacific harbor seals in rivers and
estuaries concurrent with migrations of depressed salmonids. The working
group could not determine if either pinniped species is having a significant
negative impact on any wild salmonid population, except winter steelhead
that migrate through the Ballard Locks because of the limitations of the
available data. Although the working group concluded that substantial additional
research is needed to fully address this issue, it found that existing
information on the seriously depressed status of many salmonid stocks is
sufficient to warrant actions to remove pinnipeds in areas of co-occurrence
where pinnipeds prey on depressed salmonid populations. The working group
identified the elements of a research program to assess impacts of pinniped
predation on depressed salmonids, and identified the geographic areas of
greatest concern of impacts on salmonids on each stage. The working group
could not determine ecosystem-level impacts because of the complexity of
ecosystems and the limited knowledge of how they function.

Abstract: The American Fisheries Society herein provides a list of depleted Pacific salmon, steelhead, and sea-run cutthroat stocks from California, Oregon, Idaho, and Washington, to accompany the list of rare inland fishes reported by Williams et al. (1989). The list includes 214 native naturally-spawning stocks: 101 at high risk of extinction, 58 at moderate risk of extinction, 54 of special concern, and one classified as threatened under the Endangered Species Act of 1973, and as endangered by the state of California. The decline in native salmon, steelhead, and sea-run cutthroat populations has resulted from habitat loss and damage, and inadequate passage and flows caused by hydropower, agriculture, logging and other developments; overfishing, primarily of weaker stocks in mixed-stock fisheries, and negative interactions with other fishes, including nonnative hatchery salmon and steelhead. A new paradigm that advances habitat restoration and ecosystem function rather than hatchery production is needed for many of these stocks to survive and prosper into the next century.

Abstract: The Washington State Department of Ecology initiated monitoring of marine waters in 1967 in order to assess water quality in Puget Sound, Grays Harbor, and Willapa Bay. Data are currently collected monthly for this ongoing, long-term monitoring effort by the Marine Waters Monitoring program. Monitoring of various water quality parameters during wateryears (WYs) 1996 and 1997 occurred at 29 and 25 stations, respectively, in Puget Sound each WY (WY 1996 = October 1995 through September 1996). For both Water years, five stations in Grays Harbor and six in Willapa Bay were also monitored. In this report, along with the WY 1996-97 data, five indicators of marine water column environmental condition are discussed.
Climatic conditions of WY 1996-97 were characterized by higher than normal precipitation in both years, particularly during fall and winter. Air temperatures averaged close to normal throughout the two-year period. Annual runoff of Skykomish and Chehalis Rivers were quite high, at approximately 140-150 percent of the median flow, in both years. These weather and flow conditions were evident in the sea-surface temperature and salinity of the monitoring stations. All stations showed predominately fresher sea salinity than the long-term average. Stations near rivers had a more extreme annual sea temperature range than those not near rivers.
The stratification characteristics of stations were classified into four groups: persistent, seasonal, episodic, and weak. The majority of the Puget Sound monitoring stations were either persistently (15 out of 38 stations) or seasonally (11 out of 38 stations) stratified. The degree of stratification has implications for water quality.
Dissolved oxygen (DO) concentrations <3 mg/L were measured at South Hood Canal, Penn Cove, and Discovery Bay; and <5 mg/L were found at 19 additional stations during WYs 1996-97. Observations of low DO primarily occurred in late summer to early fall but in South Hood Canal occurred year-round and reached anoxia at times. Persistent stratification co-occurred with low DO concentrations.
Very high ammonium-N concentrations (>0.14 mg/L) were seen in Budd Inlet and East Sound. High concentrations (>0.07 mg/L) were at 13 predominately South Puget Sound stations. Occurrence of consecutive months with <0.01 mg/L surface dissolved inorganic nitrogen (nitrate+nitrite plus ammonium) in combination with stratification and other indicators was used to indicate stations potentially sensitive to eutrophication. Fecal coliform bacteria counts >14 organisms/100 mL were found at 12 Puget Sound stations and seven coastal estuary stations during WY 1996-97. Of these, contamination in Grays Harbor, Willapa Bay (near the Willapa River), Commencement Bay, and inner Budd Inlet appeared chronically persistent. Other stations (e.g., Elliott Bay and Bellingham Bay) showed wintertime highs in fecal counts.

Keywords: salmon//fish//Puget Sound//contaminants
Abstract: Urban estuaries receive inputs of toxic anthropogenic substances from various sources. These chemicals can accumulate in sediments (Dexter et al. 1985) and thereby be retained in the estuary. The Hylebos Waterway in Commencement Bay, Tacoma is a severely contaminated estuary. During 1989 and 1990, juvenile chinook were sampled and found to be substantially exposed to a variety of contaminants including PAHs and CHs. Juvenile chinook from the Duwamish Waterway also show a variety of biological immunocompetence with increased mortality and reduced growth. A recent laboratory investigation demonstrates immunocompetence of juvenile chinook to be impaired by exposure to CHs and PAHs. This study focuses solely on characterizing possible exposure of juveniles.
Juv. chum from the Hylebos had significantly higher concentrations of HCB, HCBD, PCBs and DDTs, chlordanes, dieldrin, and lindane in live compared to chum from reference estuaries and hatcheries. Concentrations were 20 to 9 times higher for HCBD and HCB and 7 times higher for PCBs. Concentrations DDTs, chlordanes, dieldrin and lindane were twice as high in the livers of Hylebos fish compared to reference fish. Juv. chinook showed concentrations of HCB and HCBD to be 4 times higher, PCBs about 3 times higher and chlordanes twice as high in the liver compared to liver from reference fish.

Abstract: We estimated that during the three-year period 1996 to 1998 about 200 to 300 recreational seaweed harvesters removed 2,000 to 4,000 lb of Alaria from North Beach County Park each year. In 1997 and 1997, the percent cover of Alaria dropped form over 50% to about 15%. Compliance with the 10 lb wet weight per person daily bag limit imrpoved significantly over the three-year study, with near full compliance in 1998. Most harvesters used the recommended harvest method (cutting the leafy portion and leaving the holdfast), and at least half of the harvesters carried visible licenses. About 75% of the harvesters were female. If gender equity is a management objective, seaweed harvesting offers an important recreational opportunity for women. Harvest effort was concentrated around minus-tide series from late March to early July. The most readily accessible Alaria in the higher intertidal region was removed first. Alaria recruitment varied significantly between years, with 1997 having 5 to 6 times as many plants per quadrat as the other 2 yrs. We used a control (unharvested) beach and a treatment (harvested) beach to estimate the population, community, and ecosystem impacts of seaweed harvesting. Our sampling plan used 2-5 times as many quadrats as other Puget Sound studies reported in the literature. In 1996, both beaches showed sharp declines in Alaria percent cover suggesting a dominant natural die-off effect. In 1997, only the harvested beach showed a sharp decline suggesting a dominant harvesting effect and in 1998 neither beach showed much decline. We concluded that the control beach may have been unsuitable, because it was too far (about 4,800 ft) from the treatment beach and had somewhat different physical characteristics (e.g. more gradual slope). Our project demonstrated that there is an ample and capable volunteer workforce in the Port Townsend area to conduct a comprehensive beach monitoring program. We recommend that monitoring recreational seaweed harvest include non-game marine invertebrates (NGMI). Given the labor-intensive data gathering requirements of such a program, we feel that citizen volunteers can significantly expand the capabilities of government agencies and research universities. Our vision is a well-trained statewide labor force available to augment professional data collection activities. We make some specific recommendations that may be incorporated into statewide beach monitoring and sampling protocols.

Keywords: eelgrass//monitoring
Abstract: Although seagrasses have been identified as vital living marine resources, their distribution has not been rigorously quantified at main locations. This fact is often due to the high cost of sampling seagrass habitats, especially those with deep-water plants that cannot be sensed form aerial platforms. We present a cost-effective method of estimating basal area coverage of submersed vegetation that uses differential global positioning system data linked to underwater video images of the bottom. Our sampling design and statistical procedures are identical to estimating proportions using cluster sampling with unequal cluster sizes. This method has several advantages over other techniques: 1) confidence intervals around basal area coverage estimates permit hypothesis testing of changes over time; 2) sampling efficiency is better thansimple random sampling with quadrats; 3) deep-water zones out of the range of aerial platforms can be sampled; 4) video images provide positive identification of plants which is not possible with acoustic techniques; and 5) the techniques provide a permanent archive of visual images that can be analyzed for other bottom attributes, such as other vegetation, macro-invertebrates, and gross sediment types. This method has some limitations: 1) it is not possible to sample extremely shallow or turbid waters and under some physical structures: 2) it is impractical to sample very large regions: 3) errors in differential global positioning system data must be accounted for; and 4) seagrass density must be measured subjectively. We illustrate our sampling methods and data analysis with an example from Puget Sound.

Abstract: We conducted an underwater video and snorkel survey of the subtidal regions in the immediate vicinity of the Union Wharf, Port Townsend Washington. The purpose of the survey was to delineate the edge of eelgrass (Zostera marina) beds adjacent to the dock prior to dock reconstruction. Dense eelgrass beds were observed immediately adjacent to both the north and south sides of the outer portion of the approach ramp to the Union Wharf in depths between -4 and -10 ft. MLLW. Sparse eelgrass was observed off the southwest corner of the main dock in depths between -10 and -14 ft MLLW. Some eelgrass also was observed in the north central region of the destroyed portion of the ramp. No eelgrass was observed near the dock outside the inner harbor line. An oversize map, video of the survey, and floppy disk with integrated data is included with this report.

Abstract: Water quality data collected during the period 1991-1997 by the Port Townsend Marine Science Center citizen-based monitoring program indicate that most of Port Townsend Bay meets Washington State marine water quality standards for temperature and dissolved oxygen. Although temperatures were occasionally above state standards in the southern portion of the Bay and inside Kilisut Harbor, these readings only occurred during the warmest summer months and are most likely a natural occurrence. Occasional low dissolved oxygen readings were observed in the outer portions of the bay near Admiralty Inlet. We believe these low readings were due to significant upwelling and were not caused by human activities. Waters inside the Port of Port Townsend Boat Haven had low dissolved oxygen readings during October and November of 1996. These readings may be caused by human activities and deserve further monitoring. High fecal coliform readings were observed in the Point Hudson Marina immediately following the 1996 Wooden Boat Festival. Semi-annual underwater video eelgrass surveys indicate extensive eelgrass beds along the entire Port Townsend waterfront from the Port of Port Townsend Boat Haven to Point Hudson. Annual demersal fish abundance surveys indicate significantly different species compositions in the northern and southern portions of Port Townsend Bay. Spotted ratfish, Pacific sanddab, Dover sole and rock sole were more abundant in the northern region, while spiney dogfish, flathead sole, English sole, Pacific tomcod, Pacific herring, snake prickleback, and blackbelly eelpout were more abundant in the southern region. Juvenile (young-of-the-year) Pacific tomcod and walleye pollock showed highly variable recruitment between years. Pacific tomcod had significantly higher recruitment in 1991 and 1993, whereas walleye pollock had highest recruitment in 1996 and 1997. Spiney dogfish and spotted ratfish virtually disappeared from the survey catches starting in 1994. Snake prickleback catches during 1996 and 1997 were significantly lower than 1991-1993. Only three juvenile Pacific cod have been observed during the seven years of surveys.

Only a concerted effort and a commitment to long term research will determine the causes of changes in the North Pacific. Solutions are unlikely to come quickly and need a concerted effort.
Nowlis, J. S. and C. M. Roberts. Fisheries benefits and optimal design of marine reserves. Fishery Bulletin. In press.
Abstract: We used fishery population models to assess the potential for marine fishery reserves, areas permanently closed to fishing, to enhance long-term fishery yields. Our models included detailed life history data. They also included the key assumptions that adults did not cross reserve boundaries and that larvae mixed thoroughly across the boundary but were retained sufficiently to produce a stock-recruitment relationship for the management area. We analyzed the results of these models to determine how reserve size, fishing mortality, and life history traits, particularly population growth potential, affected the fisheries benefits from reserves. We predict that reserves will enhance catches from any overfished population that meets our assumptions, particularly heavily overfished populations with low population growth potential. We further predict that reserves can enhance catches when they make up 40% or more of fisheries management areas, significantly higher proportions than are typical of existing reserve systems. Finally, we predict that reserves in systems that meet our assumptions will reduce annual catch variation in surrounding fishing grounds. The fisheries benefits and optimal design of marine reserves in any situation depended on the life history of the species of interest as well as its rate of fishing mortality. However, the generality of our results across a range of species suggest that marine reserves are a viable fisheries management alternative.

The study objectives were to adequately describe the distribution, abundance, seasonal variations and annual variation of the intertidal and shallow subtidal benthos of the area. Representative ranges of habitats were sampled quarterly. Over 1,000 different plant and animal species were collected during the two years. The dominant groups were algae, molluscs, annelids, and crustaceans. In the intertidal, rock habitats were the richest in terms of number of species, density and biomass (and probably productivity), followed by cobble, protected soft sediment, exposed sand, and exposed gravel habitats. Strong intertidal vertical zonation was found at all but the most exposed gravel and sand sites. Subtidal study sites were consistently rich. Summer was most often the peak for species richness, abundance, and biomass and winter most often the low. The rich, complex, productive communities are to be found in rock and protected soft-sediments sites. These communities were the least variable over time and are the most vulnerable to long-term damage form an oil spill.

Keywords: birds//Puget Sound
Abstract: This paper reports on the PSAMP Monitoring Management Committee efforts to monitor the abundance of selected bird species to identify any significant changes or trends that may be related to pollution, habitat loss, or disturbance and monitor reproductive success and contaminant levels in birds. Certain species were selected for emphasis in monitoring using criteria related to usage of or dependence upon marine waters of Puget Sound, to peaks of abundance during survey periods, and to other concerns due to limited numbers or special vulnerability to human-caused mortality. Changes observed included the following: increased bird numbers in summer (63,187-105,094) over winter (131,674-273,712); a larger number of birds using southern Puget Sound during winter than summer; increased waterfowl usage in winter along shorelines, with some estuaries (including Skagit, Padilla Bay) containing large numbers of waterfowl and geese, and winter migration of grebes and loons into the Sound to use protected waters (deeper with relatively low currents) in all of Puget Sound (excluding the Strait of Juan de Fuca and portions of the San Juan Islands).
Conclusions and Concerns: Significant declines are being recorded in portions of the Pacific flyway for at least two commonly found Puget Sound diving ducks -the scoters and scaup. The rate of decline in wintering areas for declining diving ducks in Puget Sound is equal to or greater than that recorded in Alaska breeding grounds. Since 1978, there has been a significant decline in wintering scoters. Bufflehead and goldeneyes have shown a stable or slight increase in winter use of Puget Sound. Scoter decline is similar to herring spawner declines. This would be expected due to their historic reliance on forage fish spawning occurrences. Scoters and scaup were noted to use marine habitats in Puget Sound with different duck species overlapping in usage of nearshore marine habitats and different species varying with prey types, foraging style, and the portion of nearshore habitat used.
Scoters accumulate contaminants during their wintering stay. It is unknown what level of contamination will cause deleterious population effects. Scoters are environmental indicators to evaluate the health of Puget Sound. due to their widespread occurrence and consumption of shellfish and forage fish eggs. Harlequin ducks also rely on forage fish roe. The same food chains that support these migratory bird populations also sustain both anadromous and non-anadromous fish.

Abstract: This overview reports on the Puget Sound Ambient Monitoring Program (PSAMP) monitoring of bird resources in 1988. The PSAMP monitoring committee set out to monitor the abundance of selected bird species for identification of significant changes or trends potentially related to pollution, habitat loss, or disturbance. It also set out to monitor reproductive success and contaminant levels in birds. The marine mammal component was intended to provide consistent Puget Sound marine mammal population estimates and add to the body of knowledge about the effects of contaminants on marine mammals. Surveys include shorebirds, gray whales, marbled murrelets, and harbor seals.

Abstract: This paper reports the preliminary results of aerial survey for marine mammals in the inside waters of Washington and British Columbia. Objectives: estimate abundance of harbor porpoise and Dall's porpoise; examine geographic distribution of above species and harbor seals. Results: three most common species are harbor seals, harbor porpoise, and Dall's porpoise. Killer, gray and minke whales, steller sea lions, Calif. sea lions, and sea otters were also observed. Only harbor seals and harbor porpoises were seen in Strait of Georgia. The lack of marine mammal sightings in the Strait of Georgia was surprising. This is thought to be related to animals leaving or avoiding the region. The lack of Dall's porpoise in Strait of Georgia is historically consistent.

Keywords: fish//rockfish//Puget Sound//lingcod
Abstract: Rockfishes (Sebastes spp.), lingcod (Ophiodon elongatus), and kelp greenling (Hexagrammos decagrammus) are the most popular bottomfish species targeted by recreational anglers in Puget Sound. In nearshore waters, these species typically inhabit rocky and irregular bottoms, including natural reefs, artificial reefs, shipwrecks, jetties and breakwaters. A large proportion of the recreational bottomfish effort in Puget Sound occurs in the nearshore environment. Thus, in order to provide adequate protection and management for the species and their habitats, it is critical that fishery managers know how much rocky-reef habitat exists and to what extent these areas are utilized.
Since 9193, the Washington Department of Fish and Wildlife (WDFW) has used a video-acoustic technique (VAT) to conduct in-situ fish population surveys throughout the inland marine waters of the Washington. The primary objective of the VAT surveys is to provide regional estimates of nearshore rocky-reef fish populations. By using an underwater video camera, it is possible to characterize the habitat observed at each survey station. Thus, a secondary objective of the VAT surveys is to quantify the type and amount of the various habitats encountered. Using geographic information systems (GIS) software, the habitat data collected during these surveys will be used to produce maps of the nearshore rocky-reef habitats within Puget Sound. This habitat data will serve as the basis for future fish population surveys and habitat assessment studies. By identifying the rocky-reef habitats and major concentrations of rocky-reef fishes, smaller scale surveys will be signed to provide more accurate population assessments and produce more detailed maps of individual rocky reefs in Puget Sound.

Keywords: rockfish//rocky reef fish//refugia//Puget Sound//fish//fish distribution//harvest//fish harvest
Abstract: This paper discusses the effects of harvest refugia at several sites in the San Juans and Puget Sound region. It was found that the site protected from harvest for 24 years showed a dramatic difference in its abundance of large copper and quillback rockfish and lingcod compared to harvested areas. At the Edmonds refuge, copper rockfish density was 6 times greater and lingcod density was twice as great as fished sites. This response to refugia is consistent with other findings around the world. Refuge fish and shellfish are often in 2 to 25 times greater abundance than fished sites. Size increases are also commonly found in refugia areas even after only a few years. It was also noted that fishing in areas adjacent to refugia could increase catch rates with Puget Sound anglers benefiting from a system of harvest refugia.

Abstract: In February 1999, NMFS received a petition to consider 17 species of marine fishes in Puget Sound as threatened or endangered under the provisions of the ESA. The species include Pacific cod, walleye pollock, Pacific whiting, Pacific herring, and copper, quillback, and brown rockfishes. Most of these species are targeted in recreational fisheries in Puget Sound, and the petitioner used much of the information developed under previous Sportfish Restoration segments of this project. The WDFW, to the best of its ability, is taking measures to avert the siting of any species and to provide for the conservation of the species in question. The Puget Sound Groundfish Management Plan, developed in part under previous Sportfish Restoration activities, provides the framework to achieve precautionary and effective management. As such, during the present segment activities, a draft Conservation Plan was developed focused on conservative harvest strategies and a system of no-harvest refuges as the means to achieve conservation. In addition, staff developed and recommended a new daily bag limit for rockfish (one fish per day) that will begin to provide stock rebuilding for these sensitive species. Staff also consulted on other sportfish management proposals including an equitable adjustment of the lingcod fishery and removing an aggregate bag limit for bottomfish.
Catch and effort estimates were generated for bottomfish harvested in recreational fisheries in Puget Sound during 1997 and a detailed analysis of recreational bottomfish estimates was undertaken. The analysis revealed that wide disparities in catch and effort estimates occurred among state and federal creel surveys. State estimates were consistently lower than the federal Marine Recreational Fisheries Statistical Survey (MRFSS) and halibut catch estimates were far lower than the MRFSS. At present, the reliability of any survey cannot be substantiated, and the inability of state estimation system to provide an estimation framework during extensive salmon fishery closures leaves bottomfish biologist wanting for reliable recreational estimates for management.

Abstract: Rockfish and lingcod populations are in poor condition in many areas of Puget Sound. A system of no-take refuges is proposed to achieve long-term sustainable populations and fisheries. A preliminary plan suggests goals, objectives, and approaches to implement a refuge system. Project work was completed monitoring refuges in central Puget Sound and in the San Juan Islands. Future monitoring includes surveying a new Conservation Area at a former fished study site.

Keywords: Pacific cod//cod//Puget Sound//straits//biology//stocks//Port Townsend
Abstract: A stock assessment of Pacific cod was undertaken for Puget Sound. The biology of Pacific cod was reviewed to provide insights into stock structure and population dynamics. Tagging data for Puget Sound revealed that three stocks exist: a stock in the Gulf-Bellingham and San Juan Island Regions, a stock in the Strait of Juan de Fuca and Port Townsend Bay, and a stock south of Admiralty Inlet.
Catch data showed periods of high catches alternating with periods of low catches. Six of these cycles were observed since 1942 with a peak catch of 3.5 million pounds in 1980. Catches in recent years have been below the last ten-year average of 2.5 million pounds per year. Catch patterns differed among regions. The Gulf-Bellingham Management Region typically produced over half of the catch of Pacific cod during a year.
Catch rates form trawl and recreational fisheries were used as an index of abundance to assess stock condition. Catch rates in most regions and fisheries were lower in the 1980s than in the 1970s, but catch rates have been stable until 1990 in the Gulf-Bellingham Region. Catch rates for fisheries in the eastern portion of the western stock have declined, especially for the Port Townsend area. Recreational catch rates for the southern stock were higher during some years in the late 1970s and early 1980s than during recent years. The causes of the decreased catch rates are not clear. Lower catch rates corresponded to a change in oceanographic conditions but also follow a period of increased fishing effort and harvest and increased marine mammal abundance.

Abstract: The 1997 recreational catch rates from the Washington Department of Fish and Wildlife (WEFW) creel survey were estimated for rockfish, flatfish, and lingcod. Updated stock assessments reveal depressed rockfish populations in South Sound, depressed lingcod populations in North Sound, below average populations for rockfish in North Sound and above average lingcod populations in South Sound. A more detailed assessment was conducted for rockfish based upon indices of spawning. The declining catch rates combined with decreasing size composition over time resulted in depressed copper and quillback rockfish populations in North and South Sound. Further work is being developed to model lingcod and rockfish populations in Puget Sound. Surveys for Pacific cod revealed continued absence of spawning adults at their spawning grounds in central Puget Sound. However, high abundances of young-of-the-year cod were observed in the San Juan Islands during August 1998.

Keywords: Puget Sound//MPA//marine protected areas//straits//fish
Abstract: This paper reviews potential threats to Puget Sound fish communities that can likely be reduced by MPA's. Habitat alteration, particularly bulkheading and pier construction can dramatically alter habitat and exclude fishes or alter beach characteristics thereby disrupting nearshore habitats and inhabitants. Such activities include scientific or education collection, harvest of non-traditional invertebrates and intertidal fish, targeted fisheries upon intertidal vegetated habitats, shading caused by pier and dock construction, and disruption from vessel prop wash can cause a loss of eelgrass beds and disrupt the nearshore food web. Anchorages, fishing on rocky reefs, divers disturbing reproduction and egg guarding, mobile fishing gear, and dredges can cause significant disruption to food web and reproductive processes. MPA's can reduce human disturbance due to boating and fishing activities that disrupt schooling and feeding. Rocky reef fishes in Puget Sound have responded to no-take refuges with increased density, size and reproduction. Full MPA system design requires monitoring and evaluation to test if system goals and objectives are being achieved. Regional basin fish population surveys, catch and fishery monitoring, marking and tagging experiments, age-structured models, and habitat and ecosystem research are needed to answer questions on the effects and benefits of MPA's. Without testing and evaluation, MPA implementation could pose as great a risk to marine fish as continuing with the status quo. Design and siting may not match resource needs, testing and evaluation will be required to understand the resource response to the MPA and accurately predict resource responses in order to reach MPA objectives.

Abstract: Stock assessments were conducted for thirty-six bottomfish stocks in Puget Sound. Catch, effort, and survey data were assembled for North and South Sound regions for each of 18 species or species complexes. Only 28 stocks had sufficient information to determine stock status and recent trend. The majority of these stocks were in below average, depressed or critical abundance conditions. Thirteen of the 28 stocks were in decline while eight were increasing. North Sound had more stocks at average or above average conditions than South Sound, eight of eleven stocks were at below average or critical conditions. and seven stocks lacked recent information to assess stock status.

Keywords: marine birds//fish
Abstract: Membership in a stable aggregation may afford the individual with a reduction in the probability of being successfully attacked, when compared with isolated individuals. This mitigation of predation accrues passively through the effects of dilution and confusion, and actively through the differential value of spatial position and the evolution of group avoidance maneuvers. The relative safety of a given spatial position can change drastically, depending on attack strategy. Aquatic vertebrate predators (fish, birds, and marine mammals) display a wide variety of strategies when attacking schooling prey, ranging from marginal and invasive to exploitative. Evolution of avoidance maneuvers by the school is dependent on the individual correctly assessing the potential for danger and responding in a timely, coordinated fashion. Whether safety accrues differentially among school members or between school members and isolates, depends upon the size and shape of the school, the individual member's behaviour, the "behaviour" of the group, and, most importantly, the relative frequency and abundance of each predator type.

Keywords: birds//marine birds//murres//straits//Puget Sound
Abstract: On Tatoosh Island, off the Olympic Peninsula in Washington, Common Murres (Uria aalge) nest either in small subcolonies located in crevices in vertical, rocky cliff walls, or in large subcolonies located on the island top, usually at cliff's edge. Nesting murres are subject to predatory pressure form Glaucous-winged Gulls (Larus glaucescens) and Northwestern Crows (Corvus caurinus), which are resident egg predators, as well as from Peregrine Falcons (Falco peregrinus) and Bald Eagles (Haliaeetus leucocephals), which are transient predators on adults. Although subcolony size dilutes the effects of egg predators, the presence of raptors in the system negates this simple effect of dilution. Relative to conspecifics in crevice subcolonies, murres in cliff-top subcolonies are more likely to be attacked by raptors. They temporarily evacuate the subcolony in response to the presence of raptors. During subcolony evacuations, egg predators gain unhindered access to abandoned eggs. As a result, murres nesting in cliff-top subcolonies experience both delays in phenology and lowered reproductive success relative to murres nesting in crevice subcolonies. Despite continued raptor-facilitated egg predation, the majority of the murre population nests in cliff-top subcolonies, which are less than 20 years old and are growing rapidly. This suggests that new colonists are constrained by a lack of accurate information into making incorrect decisions about which subcolonies to join.

Abstract: This paper reviews the estimates of seabird mortalities attributed to the Exxon Valez oil spill. It presents a much smaller number, 30,000, murres killed by the spill rather than 350,000 to 500,000 as claimed in previous statements. It does not support the notion that the spill caused devastation or extinction.

Keywords: fish//MPA//marine protected areas
Abstract: Marine reserves have recently become a politically correct way of viewing the management of marine resources. Much of the reason for this is due to the depressed state of many of the populations that have been the mainstay of both commercial and recreational marine fisheries. The apparent failure of past management has led to a headlong rush for a paradigm shift. Marine reserves that occupy no more than about 5% of the productive habitat can provide sites for research, for monitoring natural variability, and for preserving habitat and diversity for heritage purposes. But the case for large marine reserves for fisheries management purposes has not yet been adequately made. The few available modeling studies suggest that for fisheries management purposes, marine reserves need to be on the order of 50% of the productive habitat. Analyses presented here suggest that, with reserves large, current yields can be obtained only with a considerable increase in total fishing effort and a very large increase in the mortality rates in areas open to fishing. This implies a large increase in the trawling rate, and probably associated ecological damage, in the exploited area. Even if it were desirable to manage an individual species with large marine reserves, the concept breaks down when applied to the West Coast trawl fishery, which is based on many species, each with a different habitat. A marine reserve established for overexploited groundfish provides little real protection for migratory species such as Pacific hake, but may greatly increase the cost of fishing for these species.

Abstract: Since the mid-1970’s there has been a large increase in the number of licenses for the commercial fisheries for groundfish in WA inside waters (those waters east of the Sekiu River). Production by all commercial gears increased as well, and since 1978, it has averaged over 20 million pounds annually. Several key stocks are at or near full exploitation (Pacific whiting, Eng. Sole, starry flounder, lingcod, and rockfishes) and several other stocks cannot support any substantial increase in harvest. The purpose of this report is to provide an activity profile of the commercial groundfish fleet in terms of licenses issued, vessels actively fishing, and the distribution of catch among vessels of each gear type. This information is used in discussions of fleet harvest capacity and related to the potential production from stocks of key species.

Abstract: STUDY OBJECTIVES: Mitigation/Impact Assessment. Determine effects of direct shading on marine vegetation community, in particular beds of eelgrass. METHODS: quadrat, diver eelgrass surveys. Three Puget Sound study sites with littoral zone structures were selected on the basis of the presence of homogenous eelgrass, homogenous bottom topography and bottom topography unaffected by the construction or long-term presence of the structure itself. The sites were surveyed for assessment of plant stature and counts per area during July-September 1989. A qualitatively different fourth site was also sampled at an intertidal eelgrass bed near an "oyster rack" culture structure. FINDINGS: All fixed dock structures reduced eelgrass density to zero even when visual light attenuation did not approach full darkness with little or no evidence of impacts on the stature of the surviving plants. The oyster rack site also significantly reduced eelgrass density from 244.5 plants per m 2 to 10.6 plants per m 2 directly beneath racks. In contrast, the floating dock site with the chained-anchor moorage system that allowed a swing with wind and tidal currents showed no negative impacts on the density of the eelgrass in the structure's vicinity. This may be due to the flexible nature and movement of the dock and the resulting lack of shading cast continuously over any given bottom area. CONCLUSIONS: The authors concluded that construction of partially shading types of structures, floating or on pilings, can be expected to largely eliminate the existing macroflora with little chance for replacement plant growth on new introduced solid structures. Algae species also appear to be impacted by shading structures. Other impacts they would expect over time include: altered sediment distribution and topography along piling lines, tidal drainage streams created by topographic changes, and substrates in the immediate vicinity of piling structures to be enriched with calcareous debris from barnacles and mollusks inhabiting the structures hard surfaces.

Abstract: This study investigates the potential habitat quality element of shade by overhanging trees and other vegetation on upper intertidal surf smelt spawning beaches suggested by previous Puget Sound surf smelt studies describing sun-exposed spawn as "dried to a crisp" in exposed worse case conditions during hot summer months. This report summarizes preliminary data comparing in situ incubating surf smelt mortalities found in coupled pairs of adjacent shaded and sun-exposed spawning sites in northern Puget Sound in the summers of 1990-1998.
The data indicated a very significant difference between the shaded and unshaded mortality data supporting the notion that overhanging shade positively impacts surf smelt survival during summer months in the Puget Sound basin by lowering ambient temperatures on a micro-habitat scale.

Abstract: On 24 March 1989, the oil tanker "Exxon Valdez" spilled 260,000 barrels of crude oil in Prince William Sound, Alaska. Oil eventually drifted over 30,000 km super of coastal and offshore water occupied by approximately one million marine birds. More than 30,000 dead birds of 90 species were retrieved from polluted areas by 1 August 1989. Of those identified, murres (74%), other alcids (7.0%), and sea ducks (5.3%) suffered the highest mortality from oil, and most (88%) birds were killed outside of Prince William Sound. A colony of 129,000 murres at the Barren Island was probably devastated. Another 7,000 birds were retrieved between 1 August and 13 October, but most of those birds appeared to have died from natural causes. This later die-off was composed largely of shearwaters and other procellariids (51%), gulls (22%), and puffins (14%). Based on aerial and ship-based surveys for populations at risk, and extrapolating from the number of dead birds recovered, we estimate that the total kill from oil pollution was from 100,000 to 300,000 birds.

Abstract: We examined experimentally the effects of disturbances caused by pedestrian traffic on the animals and plants living on an intertidal rocky shore in southeastern Australia. Individual footsteps damaged some animals, but the percentage of animals that were crushed were low, Molluscs, except large limpets, were more often dislodged than crushed, and some damage was sustained by barnacles and mussels. The survival of individuals of two gastropod species, Bembicium nanum and Austrocochlea constricta, were not affected by dislodgement, because they quickly righted themselves. The limpet Cellana tramoserica was not damaged by being kicked or stepped on. The dominant plant on these shores, the brown alga Hormosira banksii, was easily damaged, with 20% of the biomass of individual plants being removed by a single footstep. The amount of tissue lost increased with the number of footsteps, with a maximum loss of approximately 75%. We investigated the effects of three levels of sustained trampling (33 d of trampling, spread over 4 mo) on the organisms in three habitats: Hormosira Mats, Coralline Algae Mats, and Bare Rock. The algal mats were most affected by trampling. Hormosira Mats were damaged severely by high- and low-intensity trampling. Upright Coralline algae located in the Coralline Algal Mats were damaged by high-intensity trampling. Numbers of the gastropod Turbo undulatus in both of these habitats were reduced. The Bare Rock habitat was not affected significantly by trampling. Even after > 400 d of recovery, Hormosira cover was only 60%, three quarters of the value of control areas. The indirect effect of increased mollusc abundance was still apparent. Trampling by visitors could result in replacement of the Hormosira mat species assemblage with "bare" rock and grazing molluscs, and trampling should be considered as a disturbance capable of directly and indirectly influencing intertidal populations on rocky shores.

Abstract: Sixth report of the Puget sound Ambient Monitoring Program: Recent findings about the health of Puget Sound indicate that, although some aspects of the Sound's environmental health may be improving, its ecosystem and biological resources continue to suffer damaging effects resulting form the actions and by-products of our society.
Improvements documented over the past several years include steady or increasing populations of some organisms in Puget Sound and decreases in some types of contamination in some areas of Puget Sound. Evidence of continued problems, including the poor or declining condition of a wide variety of marine organisms in Puget Sound, tempers these observations. The continuing problems may be related, at least in part, to changes our society has made to the physical environment and to contamination of the environment by toxic chemicals, fecal bacteria and excess nutrients.
This is the sixth Puget Sound Update, a report for residents of the region about the overall health of Puget Sound. The conclusions in the Update are based mainly on scientific results of the Puget Sound Ambient Monitoring Program (PSAMP). This report looks beyond the PSAMP as well, including monitoring data from other important efforts to evaluate Puget Sound's waters, sediments, nearshore habitats and biological resources. Information generally reflects conditions through 1995, though in some cases only older data were available and in other cases results were able to access data through 1995 and 1997.

Abstract: This update presents the findings of the Puget Sound Ambient Monitoring Program (PSAMP), a longterm effort to investigate environmental trends and improve decision-making and monitoring. It reports well-documented environmental degradation in Puget Sound with degradation signs reflected in a variety of organisms appearing to be in poor condition with declining numbers. Signs of degradation include increased levels of fecal contamination in shellfish growing areas near increasing residential and commercial land development and increased incidence of liver lesions in Eng. sole possibly reflecting increased levels of such contaminants as PAH's from highly developed urban and industrial areas. Many species relying on Puget Sound are in decline, including Pacific herring, rockfish, coho salmon, scoters grebes, great blue herons, and orca whales. Species numbers and diversity have been declining suggesting widespread habitat loss or degradation, harvest pressure impacts to the food web and natural variations in marine productivity. Increased scientific assessment is needed to understand causes and implications of these declines.

Abstract: This paper reports on pinniped deaths over the last 18 years responded to by the Marine Animal Resource Center (MARC). These pinnipeds were: Pacific harbor seal, California sea lion, northern fur seal, northern elephant seal, and steller sea lion. The harbor seal is the most abundant marine mammal in Puget Sound and is therefore the seal to receive the most calls on. The majority of calls concerning harbor seal pups occur between April and October during birthing period. Many Calif. sea lions have died as a result of gunshot wounds. On the Washington coast, a chemical spill caused the death of 40 northern fur seals due to chemical exposure. Northern elephant seals were found during molting. The most significant event for the steller sea lion, which is now on the endangered species list, was the finding of 32 animals along Washington coast found dead form gunshot wounds. Sightings and deaths are increasing. Results of herpes virus, distemper, toxicological problems in gray whales, and a disturbing trend of shootings of harbor seal pups and yearlings was documented.

Abstract: Boat surveys along randomly placed line transects were conducted from June to August 1991 and June to October 1992 to determine distribution and abundance of and habitat use by harbor porpoises (Phocoena phocoena) off the northern San Juan Islands, Washington. There were 301 sightings (average 4.4 sightings/h) of 526 harbor porpoise during 73 random boat surveys, with group sizes of 1 to 8 individuals (mean=1.87, SE=0.06, n=278). An estimated 299 harbor porpoise (1.26 porpoise/km super (2), SE=0.20) were distributed in an aggregated pattern within a 237 km super(2) area (10% of Washington Sound), indicating that a large proportion (30%) of harbor porpoise in Washington Sound occur in the northern San Juan Islands. Harbor porpoises were distributed over a depth range from 20.1 to 235.0 m (mean=141.6 m, SE=2.43, n=275) and were observed more than expected (P<0.05) in depths greater than 125 m and over shallow slopes (<10%) and observed less than expected (P<0.05) in depths less than 75 m. Porpoise occurred at sea surface temperatures of 10.1 degree to 16.3 degree C and were sighted more frequently than expected (P<0.05) in water temperatures of 11 degree to 12 degree C. Boat surveys along fixed location transects indicated distribution was similar between 1991 and 1992. The occurrence of harbor porpoise in deep water, at cooler sea surface temperatures, over shallow sloping seafloor, and in tidally mixed regions (owing to currents and tide rips) within our study area may, collectively, affect prey distribution and associated harbor porpoise distribution.

Abstracts: Densities of copper rockfish (Sebastes caurinus) and quillback rockfish (Sebastes maliger) differ significantly among sites in the northern Strait of Georgia. To determine whether among-site density differences are associated with habitat characteristics of the sites, rockfish densities and habitat characteristics were measured at 12 sites during SCUBA surveys in 1984 and 1985. Quillback rockfish densities were greater in areas of high relief, broken rock, and high percentage cover of flat-bladed kelp, especially on deep transects. Copper rockfish densities were also greater in high relief areas, but effects of other habitat characteristics were not significant. Copper rockfish appeared to be more widely distributed than quillback rockfish over the range of habitats and depths surveyed.

Abstract: Observations on habitat requirements of three juvenile rockfish species were made from a submersible at depths >20m. The author notes that two species (S. maliger and S. ruberrimus) were strongly associated with more complex rock habitats but were segregated by depth while the other (S. elongatus) was more commonly associated with mud/cobble areas. Sizes of the three species increased with depth.

Keywords: nearshore//nearshore habitats
Abstract: The Washington State Department of Natural Resources, in cooperation with other state and federal agencies, has developed a program to remotely sense nearshore vegetation (intertidal and shallow subtidal). The classified nearshore data are integrated into an existing geographic information system for spatial analysis to support aquatic land use planning and management decisions. In 1996, a data set for the greater Bellingham Bay area in Northern Puget Sound was completed. Program methods incorporate advances in remote sensing technologies to overcome the constraints of the target geography, which prevent the use of more traditional inventory methods. The multispectral image data were collected by a Compact Airborne Spectrographic Imager (CASI) sensor, configured to collect 11 bands of data (from the visible to the near infrared range) with square, four meter pixels. Color infrared (CIR) photography was acquired simultaneously from the same aerial platform. Marine scientists collected field data located by a differential Global Positioning System (DGPS) or annotated aerial photographs during the same season as the image data were collected. A hybrid of supervised and unsupervised image classification techniques produced mapping of eight vegetation types. Field data were used to conduct a classification accuracy assessment. As a result of the project, two digital and two hard copy products have been defined.

Abstract: REGION: PNW Species: chum and pink juvenile salmon STUDY OBJECTIVES: Assess the effects of wharf lighting at the U.S. Naval Submarine Base Bangor on outmigrating juvenile salmon in Hood Canal. Chum being the principal salmonid in Hood Canal and pink the second most abundant. METHODS: Net sampling, hydroacoustic monitoring and visual observations in areas adjacent to the wharf. Stomach analysis. RESULTS: Although salmon were observed to congregate below the lights. Increased salmon catch in the nearshore areas at the wharf were most likely caused by the presence of prey. No large-scale aggregation in the wharf area appeared to result from Mode I lighting of 2-13 lux. Mode II and III lights in intensities of 200-400 lux appeared to attract and delay chum for 1-2 days. It was also speculated that they remained in the area due to food availability. It was concluded that too few tests were run under these conditions to be conclusive. Predation on outmigrating salmon in the wharf area was considered insignificant, as <4% of the predators caught contained salmonid remains, and few of the predators were implicated in consumption of salmonids (cutthroat and staghorn sculpin in Hood Canal) were present with a total catch of <10 during February-July 1979 which included 310 purse seine sets, 58 beach sets and 35 townet sets. Catch of coho and cutthroat trout did not increase with lighting.

Abstract: The Olympia oyster (Ostrea lurida) is a native to the state of Washington. Once the basis for a thriving, statewide oyster industry, its numbers were drastically reduced by the mid 1940's. Water quality and overharvesting are thought to be the major factors in its near demise. The Pacific oyster (Croassostrea gigas) has since replaced the Olympia oyster in Washington and world markets. The Washington Dept. of Fish and Wildlife is now developing an Olympia oyster stock rebuilding strategy. The tools of the strategy to restore the Olympia oyster within its historical geographic range are quite simple, but offer many challenges. Key elements of the draft strategy include historical and current distribution, habitat and water quality impacts, interspecies interactions, and Tribal co-management. Partnering with Tribes, local commercial shellfish interests, and the public provide new opportunities for restoring the Olympia oyster. It is a top priority for state management of this species.
Abstract: A medium scale landslide (2153 m3) deposited sediment on to an intertidal beach on the north side of Point Williams, Seattle, Washington on 4 April 1991. Within 23 days of the slide, high tides and rain carried 77% of the sediment to nearshore waters and north through a seasonal kelp bed immediately adjacent to the slide area. Transects were placed in north and unimpacted south kelp beds and monitored seasonally for algal community and densities. Significant differences in north and south kelp bed costaria costata, Laminaria sp. and Nereocystis luetkana densities occurred during spring. No other community or density differences were found. Irradiance values of the two beds differed during winter months but were similar for the rest of the year. Significant differences in spring kelp densities may be attributed to short-term impacts of landslide sediment introduced to the kelp bed during early kelp growth stages. However, the landslide did not appear to effect the kelp community after the observed spring depression. Larger landslides may have more extensive impacts.

Keywords: rockfish//vegetation//straits//nearshore vegetation//nearshore//vegetation//fish
Abstract: The community composition and trophic use of the drift vegetation habitat by pre-settlement juvenile splitnose rockfish was documented in June, August, and October 1992 in the San Juan Archipelago, Washington, USA. Fucus spp., Zostera spp., and Nerocystis leukeana were dominant vegetation for the months sampled. Juvenile S. diploproa collected from the drift vegetation habitat fed mainly on planktonic organisms, including copepods and cladocernas, during June and August. In October, diets shifted to larger epiphytic prey and were dominated by 1 amphipod species. Of 5 major prey taxa, 3 had significanlty different densities in drift vegetation and nearby open water habitats. Prey taxa were not dominant in the drift vegetation habitat in June and August, indicating a high degree of prey selection during these months. In October, dominant prey taxa made up a large proportion of the crustacean community in the drift vegetation habitat and less prey selection occurred. Community indices of the drift vegetation habitat were up to twice as high as those of the adjacent open water habitat for the 3 mo sampled due to vegetation associated crustaceans. Drift vegetation provides nearshore habitat features to pelagic systems. It provides food, refuge, and possibly transport from offshore to nearshore habitats for a number of recreationally and commercially important species.

Abstract: This paper presents the findings of two pilot studies defining basic features of the two dominant understory habitats in Puget Sound and the Strait of Juan de Fuca. These are bull kelp, Nereocystis leutkeana, and giant kelp, Macrocystis integrigolia, which together support wonderfully complex nearshore fish and plant assemblages. The two pilot studies defined the basic features of the understory habitats. A number of striking differences within and between kelp beds in Puget Sound compared to Strait of Juan de Fuca were documented. Variations in understory communities with bed type, location, and season highlights the need to define the specific goals of preservation and restoration activities prior to implementation of management activities such as Marine Area Preserves. Preservation and restoration efforts will be less effective if species targeted for restoration and preservation are not well defined relative to the location and species of habitat under consideration. The variation in this study also highlights the need for detailed long-term studies for successful habitat restoration and preservation.

Abstract: Kelp habitats in Washington state, including the Strait of Juan de Fuca, are classified as a critical habitat for a number of federally listed, proposed listed, and declining stocks, including chinook, coho and chum salmon, quillback, copper and brown rockfish, surf smelt, sand lance and northern abalone. The Strait of Juan de Fuca supports the majority of kelp resources in the state of Washington. Despite this importance, virtually no information exists on kelp habitat community structure for the Strait of Juan de Fuca. This study defined understory composition of dominant kelp habitats of the Strait. The understory composition of two Macrocystis integrifolia and Nereocystis leutkeana beds were sampled seasonally for one year. Variables assessed included macroalgal composition and three commercially and recreationally important species of urchin and one species of abalone. Similarities and differences were found with bed type, season, and geographic location. Similarities included strong seasonal variation in understory cover, and the dominance of the perennial, understory kelp Pterygophora californcia. Both types were also similar in their difference form understory communities described for Puget Sound kelp beds.
Differences between the two kelp bed types included variation in total algal cover. Macrocystis beds showed a seasonal variation in total cover and algal composition and had greater overall percent cover, to which M. integrifolia contributed seasonally. Nereocystis beds showed seasonal changes in percent algal cover. However N. leukeana did not contribute to the understory algal over of these beds. Neocystis beds had higher total number of urchins and abalone than Macrosystis beds.
Recent increases in kelp habitat management activities, combined with differences in kelp community with seabed type and location observed in this study underscore the need for well-defined goals and detailed site studies on successful kelp habitat manangement, including restoration and preservation.

Keywords: salmon//overwater structures//human impacts//hearshore fish
Abstract: This report presents the results of Phase II of a 3-phase research program to determine whether ferry terminals affect migrating juvenile salmon, and if so, how future design of ferry terminals and modifications to both terminals and operations can mitigate those impacts. Phase I resulted in a report synthesizing the technical knowledge regarding the potential effects of shoreline structures on migrating juvenile salmon. This report summarizes our results from Phase II pilot field studies at the Port Townsend ferry terminal in spring 1999 and provides recommendations for proposed on-site tests of the effects of a range of different WSDOT ferry terminals and vessel activity patterns in Phase III (spring- winter 2000). The overall goal of Phase II was to perform pilot field experiments with releases of hatchery chum and chinook fry to test whether the Port Townsend terminal stops or delays the natural migration of juvenile salmon. Monitoring methods included diving surveys, beach seining surveys, single-beam and split-beam hydroacoustics, remote underwater video and in situ light sensors. The surface observations, underwater video, and the single-beam and split-beam hydroacoustics confirmed that the chinook migrated from the release point directly to the shadow line underneath the terminal. The chinook fry stopped at the shadow line and then displayed consistent behavior of swimming from the darkness of the shadow line and remained near the bottom into the light to feed at the surface. As the sun set and the shadow line progressed further under the terminal, the school appeared to follow the shadowline under the terminal. The fundamental question of whether ferry terminals present a barrier to juvenile salmon migration remains unanswered.

Abstract: This project is assessing whether ferry terminals affect juvenile salmon migrating along estuarine and nearshore marine environments and, if so, how design of and modifications to both ferry terminals and operations can mitigate those impacts. This project has three phases. This report summarizes results from Phase I (status of knowledge, initial terminal surveys) and implications for Phase II and III research.
This study addressed three issues about over-water structures impacts on juvenile salmon: 1) alteration in migratory behavior, 2) reduction in prey production and availability, and 3) increased predation. An assessment of over 60 direct sources of information found evidence that juvenile salmon react to shadows and other artifacts in the shoreline environment created by shoreline structures. While changes in light have been shown to affect salmon migration behavior and thus potentially place them at increased mortality risk we found no quantitative information on the significance of these behavioral responses to juvenile salmon survival. Juvenile salmon also encounter limited prey resources under shoreline structures when important habitat, such as eelgrass (Zostera marina), is disturbed. Modifications to light, temperature, salinity, nutrient levels, and wave action beneath an overwater structure influences the rate of photosynthesis, plant distribution, and survival of specific plant species that directly or indirectly support prey resource composition and production. Despite considerable speculation about increased predation around docks, quantitative evidence for significant increases in predation on salmon associated with docks is lacking.
It also conducted short-term underwater diving and video surveys at five ferry terminals (Clinton, Kingston, Port Townsend, Seattle, and Vashon) to gather preliminary information on the relationships among variations in overwater structures, fish distribution and relative abundance, light conditions, biological communities, and potential predators. Juvenile salmon were observed migrating under several structures.
Existing information indicates that the effects of shoreline structures on migrating juvenile salmon may vary, depending on the design and orientation of the shoreline structure, extent of alteration of the underwater light field, and presence of artificial light. However, our understanding of the significance of short-tem delays in the salmons' migration and cumulative or synergistic effects is insufficient to provide the quantitative relationship that would be necessary as the basis for developing, retrofitting, or making design modifications. Field studies are recommended.

Abstract: Developed in response to the need for procedures that quantitatively assess the function of estuarine wetlands and associated nearshore habitats for fish and wildlife. Thus far, a systematic approach for measuring the function of estuarine wetlands and nearshore habitats that considers the factors has not been available. Consequently, restoration and creation of estuarine habitats have proceeded haphazardly. Without such procedures, the scientific knowledge required to link the characteristics of estuarine habitats to their function in support of fish and wildlife will not emerge. The approach of the Protocol, and of the procedures and measurements it recommends, is intended to bridge the gap between estuarine habitat characteristics and the habitat's function to support fish and wildlife.

Abstract: STUDY OBJECTIVES: Describe the functional trophic relationships between juvenile chum and pink salmon and their food resources as interpreted from the results of over three years of studies in hood Canal specifically describing: 1) the temporal and spatial prey composition and consumption by juvenile chum and pink; 2) the temporal and spatial composition of epibenthic and neritic zooplankton communities; 3) evaluate the characteristic selective predation by juvenile chum and pink salmon upon "available" zooplankton; 4) evaluate the trophic importance of representative nearshore habitats; 5) relate the observed outmigration behavior of juvenile chum and pink salmon with their food habits and distribution and composition of prey resources, and 6) evaluate the potential for a limited "carrying capacity".METHODS: Beach seine, townet, stomach content analyses, epibenthic pump sampling, neritic zooplankton net sampling, otolith determinations. RESULTS: Prey: Immediately upon entry into Hood Canal fry (30-40mm) fed predominately on epibenthos, including harpacticoid copepods, gammarid amphipods, pholychaete annelids and crustacea eggs. After reaching 45-55 mm, they fed upon neritic organisms such as euphausiids, calanoid copepods, and hyperiid amphipods. Pink fry prey was dominated by calanoid copepods and copepod larvae. Epibenthic organisms were not prevalent in their diet. For chum, harpacticoid copepods formed the major dietary components. Diel shift in prey composition for chum and pink were found with both chum and pink feeding at a reduced level throughout the day. Densities of total epibenthic organisms were similar across sites. However, densities of harpacticoid copepods tended to be more variable with the highest densities found in eelgrass habitat. A general decline in harpacticoid copepod densities appeared to coincide with the early spring peak densities of juvenile chum in shallow sublittoral habitats. This suggests that epibenthic-feeding chums could be involved in depressing harpacticoid populations during the most intensive outmigration period. Intense size-specific predation depressed the mean size distributions of harpacticoids during the peak salmonid outmigration.
MIGRATION BEHAVIOR AND PREY RESOURCES: Speed of outmigration and length of residence in shallow sublittoral and neritic habitats appeared to be directly related to availability and density of preferred prey organisms. Residence times were shorter due to low prey availability. The chum may vary their migration rate according to the availability of large neritic zooplanktors. Chum 48-53mm migrated at a rate of approximately 8 km/day in April and 5 km/ in June. Schools of juvenile chum appear to disperse at night and move slightly offshore. Until reaching 45-50 mm, they continue to migrate through shallow sublittoral habitats during the day. Findings indicated that Hood Canal chum fry (30-45mm) fed extensively upon small, densely distributed harpacticoid copepods, appearing to select the largest copepods available. Depending upon fish size, residence time may be a function of prey abundance in both epibenthic and neritic zooplankton communities. PREY ABUNDANCE: The highest standing stock estimates of these organisms occurred at an eelgrass covered delta, Devil's Hole Delta. This is consistent with other studies, where the highest densities of harpacticoid copepods occur in thick eelgrass stands of 4-5 times higher in sand habitat without eelgrass. Standing stocks of gammarid amphipods, appear to be higher in more current swept habitats with coarser substrates. Gammarids, a principal prey of (45-60mm) chum. The extensive growths of marine macroalgae, (laminaria, ulva) typify the more current swept, shallow sublittoral habitats that contribute significantly to gammarid standing stocks. Neritic habitat with large zooplankters is the principal foraging habitat of juvenile chum over 50-55m with intense feeding on the diel-migrating calanoid copepods.
Existing data supports the following assumptions: 1) salmon fry are morphologically and bioenergetically constrained in the sizes and species of prey organisms which they can consume and still obtain a daily ration sufficient to maintain growth; 2) the response of the outmigration of fry to inadequate prey composition or density is an increased migration rate which reduces marine survival, and 3) the availability of these "optimal" prey resources is finite and a function of time given the recent history of predation by outmigrating salmon fry and other planktivorous predators. EPIBENTHIC CARRYING CAPACITY: Juvenile chum demonstrate a preferred harpacticoid prey size range. The chum daily ration was estimated to be 25% at 35-40 mm size and 20% at 40-50mm size. Residence in Hood Canal was estimated to be two weeks with fish growing from 30-35mm fish to 50+mm when they can effectively feed upon neritic organisms. CHUM OUTMIGRATION AND CARRYING CAPACITY: Estimates of epibenthic prey abundances suggest the need to adjust total hatchery release timing and densities to the availability of preferred prey. Diverse times and size distributions of released fry could minimize overexploitation of prey taxa. CONCLUSIONS: Otolith markings could document estuarine and nearshore residence. Very limited information on neritic feeding is available. Predator-prey interactions require further study of copepod prey communities. The hypothesis of low survival for juvenile chum with short residence estimates in Hood Canal require further analysis and stock comparisons. The use of light, temperature, nutrients, detritus decomposition, and microbial colonization, chlorophyll a production, which could be directly involved in zooplankton population expansion and timing, could be used as predictors of prey availability.

Keywords: birds//seabirds//murrelet//Puget Sound
Abstract: Marbled Murrelets occur in Puget Sound marine habitats in relatively low numbers. The rates of occurrence of murrelets on censuses within marine habitats are generally low. Further analysis is required to determine if low occurrence rates are a general function of the movement of birds, or their consistent occurrence on particular censuses and not on others. Qualitative data indicate that Marbled Murrelet abundance in Puget Sound is now lower than earlier this century. Such long-term information is unavailable for Marbled Murrelets along the Pacific Ocean coast of Washington. Census data from nearshore water of the Pacific Ocean off Grays Harbor indicate that Marbled Murrelet abundance is reduced there since 1989 and especially in 1993. This pattern is also reflected in several other more oceanic species suggesting basic and widespread changes in marine carrying capacity.

Keywords: seabirds//birds
Abstract: The rates of occurrence of dead birds were determined for beach and water segment censuses in 1978 and 1979 in the inland marine waters of Washington. There were 110 birds of 25 species found dead on beach censuses. The rates of occurrence of dead birds were low in comparison with other studies: beach censuses--0 to 1.47 birds/km; aerial-shoreline censuses--0 to 4.7 birds/10 super(3) km; aerial-open water censuses--0 to 9.0 birds/10 super(3) km; ferry-shoreline censuses--0 to 6.9 birds/10 super(3) km; and ferry-open water censuses--0 to 9.3 birds/10 super(3) km. The rates of occurrence of dead birds on study area beaches were decidedly lower than comparable values from Washington beaches facing the Pacific Ocean.

Sumaila, U. R. Protected marine reserves as fisheries management tools: a bioeconomic analysis. Fisheries Research. 37:287-296.
Keywords: MPA//fish//harvest//fishery//economics
Abstract: This paper develops a dynamic computational bioeconomic model with the objective of assessing protected marine reserves as fisheries management tools. Data on the North East Atlantic cod stock are used to determine the bioeconomically optimal size of a marine reserve for the Barents Sea cod fishery, as a function of the net transfer rate between the protected and unprotected areas of the marine habitat. The single agent model developed, allows for the occurrence of a shock to the system in the form of severe recruitment failure in the non-protected area. Two key results emerge from the study. First, establishment of marine reserves are bioeconomically beneficial when net transfer rates for cod are 'reasonably' high and reserve sites are large: large reserves provide good protection for the stock in the face of the shock, while high transfer rates make the protected fish available for harvesting after the shock has occurred. Further, optimally chosen reserve size when net transfer rates are high, also mitigates against biological losses. Second, when net transfer rates are low, the establishment of marine reserves does not mitigate against losses in the discounted economic rent, while they tend to be efficient in mitigating against biological losses.

Abstract: Movements and haul-out patterns of the harbor seal (Phoca vitulina richardsi) have been studied with a variety of methods, including observations of seals with distinctly marked pelages, colored tags, or radio transmitters attached to rear flippers. We radio-tagged harbor seals to assess diving behavior and haul-out site use off the San Juan Islands, Washington; an inland waterway characterized by numerous islands, a tidal range of 3.6 m, strong currents (maximum 7.7 km/h) and a rocky shoreline. Haul-out sites include reefs and rocky intertidal zones of islands. Our objectives were to: (1) determine duration of dive and time at surface for various aquatic behaviors; (2) compare behaviors and duration of dives in the daytime and at night; (3) locate foraging areas, and (4) determine faithfulness to particular haul-out sites.

Keywords: marine mammals//northwest straits//straits
Abstract: Disturbances to harbor seals, Phoca vitulina richardsi, during 1991 and 1992 pupping seasons were observed at Puffin Island, Clements Reef, and Skipjack Island in Washington State. Harassment (greater than or equal to one seal entering the water) of seals ashore was common (greater than or equal to 71% of survey days) and primarily caused by powerboat operators approaching to observe seals. Recovery (number of seals on a haul-out site returned to preharassment levels) following harassment was less at Puffin Island (19%) than at Clements Reef(54%) and Skipjack Island (45%). Additionally, seals were more vigilant (P<0.003) at Puffin Island than at the other two locations. These results indicated that seals at Puffin Island were less tolerant of disturbance than seals at other sites. This could possibly be attributed to a greater (P<0.05) percentage of pups ashore (17%) than at Clements Reef (3%) and Skipjack Island (3%). Because of this, we expected that powerboats would disturb seals from greater distances at Puffin Island. To test this, we used a theodolite to determine distance between seals and an approaching vessel at Puffin Island and Clements Reef. There was, however, no significant (P>0.05) difference in distances at which disturbances occurred. The most notable difference in distance of disturbance was between initial and subsequent harassments during a haul-out period. Those seals remaining or returning to shore after harassment were more tolerant of powerboats, allowing significantly (P<0.05) closer approaches than those initially harassed. Seals detected (head raised and oriented toward the potential disturbance) a powerboat at a mean distance of 264 m, and harassments occurred when boats approached, on average, to within 144 m. Results of this study exemplify the variability in reaction to disturbance and the necessity for considering these differences for minimizing disturbance.

Abstract: SPECIES eelgrass STUDY OJBECTIVES: Mitigation/impact Assessment. Understand the effects of ferry terminals and ferry operations on eelgrass meadows in Puget Sound. Investigate mitigating technological and transplantation measures. METHODS: field studies at three ferry terminals located at Clinton, Edmonds and Port Townsend, Washington, two days for each terminal from July 29- August 6, 1994. Eelgrass survey included three transects with quadrats placed at 5 m intervals w/ recordings of shoot density, depth and time. Shoot samples harvested, dried and weighed with epiphytes scraped. Photosynthetically active radiation (PAR) recorded at 5-minute intervals throughout the day. Sensors were placed at mid-depth of each transect with the mean of 5-10 readings collected over a 1-minute interval being recorded. At the Clinton Terminal, divers observed and mapped propeller wash plumes for nine arrivals and departures on October 3, 1994. On August 5, 1995, at a point where eelgrass was absent but would normally occur, PAR and bottom currents. Between June 1991 and April 1996, long-term in-situ growth studies were conducted near Battelle Marine Sciences Laboratory with a growth rate and PAR measured and recorded. Irradiance requirements were evaluated in a divided tank at Battelle. Evaluation of alternative technologies to mitigate light reduction included clear plastic inserts, aluminum foil and halogen lamps. The study included an assay of sediment substrata requirements for six substrates with five replicates for each substrata type. OBSERVATIONAL: divers made qualitative observations on macrofauna and flora as to species present and differences among terminals.
PHYSICAL AND BIOLOGICAL DISTURBANCE ASSESSMENT RESULTS:Irradiance measures under the terminals are very low likely causing eelgrass loss near the terminals. Propeller wash, bioturbation and other physical disturbances may be contributing to the loss. Hydraulic pile insertion and maintenance activities have likely eliminated eelgrass around the terminals. Seastar and crab densities may be responsible for retarded recruitment of eelgrass. The "reef" effect of the terminal, its pilings and piling communities enhance habitat for seastars and crab whose foraging disrupts eelgrass. The propeller plume is believed to frequently induce reduced irradiance. The propeller wash was observed to scour and redistribute sediments and associated biota and lower irradiance beyond a critical threshold of survival. A "disturbed" ring barren of eelgrass is evident adjacent to the slip channel. A bubble plume was observed to persist following arrivals and departures. Bubbles were believed to reduce irradiance on the bottom similar to suspended sediments. Erosion of eelgrass by propeller wash has likely caused some loss. Eelgrass does not generally occur in high current areas in Puget Sound. Propellers accelerated current much faster than tidal forces. It is believed that this acceleration can have a major influence on erosion of established meadows and establishment of new seedlings.
Long term growth monitoring, both in the field and in the chambers, indicate a strong seasonal growth pattern tied to irradiance with low growth in the winter, dramatic increases in early spring, intermediate growth in summer, and declines in autumn. Studies have shown that if light is reduced below a given level for a week, the plants will die. Studies indicated that eelgrass possesses a strategy for maintaining growth under less than optimal light conditions which could help sustain growth near or under terminals. This strategy includes seasonal changes in plant biomass allocation, respiration, and chlorophyll concentrations.
Eelgrass grows in a wide variety of sediment types: fine sands, mud gravel and cobble. Although, the plants grow best in organically rich fine sediments, they are also able to grow on larger substrates due to their assimilation of inorganic nutrients through roots and leaves. Therefore eelgrass can be planted in a variety of sediment types as long as nutrients are available and physical disturbances such as waves and currents don't dislodge plants.
EXPECTED TERMINAL EXPANSION EFFECTS: Ferry propeller wash impacts can be avoided by moving slips further offshore. Use of glass inserts, lengthening the terminal, reflective paint and halogen lights could enhance light conditions required for eelgrass growth. However, more energy conservative measures such as the use of plastic deck materials and the use of reflective material under the dock are more highly recommended. Changes to substrate and piling communities can be reduced by using concrete pilings requiring 1/3 fewer pilings. This will reduce bioturbation while allowing in increased light. Specific terminal areas were identified as potential areas where disturbances can be eliminated and eelgrass transplants can be most successfully established.

Abstract: Eelgrass, kelp and macrophytes.STUDY OBJECTIVES: Impact Assessment. Summarizes the spatial extent of the wetland and nearshore plant assemblages in Puget Sound and contrasts this with historical distributions. METHODS: literature/data search summarizing quantitative data. RESULTS: Declines in tidal marshes are the most well quantified indicating 73% decline in area since the late 1800's due to diking, filling, and dredging for agriculture and port development. Due to the lack of comprehensive eelgrass data, a similar assessment is not possible for eelgrass. However, loss has definitely taken place due to similar development and water quality. In contrast, kelp forests have been on the rise due to changes in substrata and water quality. Sediment reduction and increased nutrient runoff ( i.e. high nitrate concentrations) increase kelp colonization. In addition, a significant introduction of macrophytes (i.e. spartina, z. japonica, sargassum weed, etc.) has occurred throughout Puget Sound. The quantification of these specific changes is not possible due to a lack of earlier comparable data. The general lack of comprehensive and quantitative historical data limits an analysis of historical changes. CONCLUSIONS: New records should be developed for documenting changes in specific habitats for the purposes of detecting changes. Changes in kelp distribution require further exploration as to causal factors. Subtidal distribution of eelgrass and the factors affecting that distribution (i.e. increased phytoplankton blooms, river-borne sediment changes etc.) should be mapped, monitored and investigated. Development of quantitative records in the form of GIS including habitat, water quality, and physical alternations should be undertaken.

Abstract: Investigated the effect of CO2-enrichment on productivity of two acquatic plant species [Zostera marina L.lNereocystis leutkeana (Mert.) P. & R.] that form significant components of coastal ecosystems in the Pacific Northwest. Short-term (i.e. 2-hr) experiments showed that doublingCO2 resulted in up to a 2.5 fold increase in Zostera net apparent productivity (NAP). Nerocystis NAP was increased 2.2-2.8 fold. In experiments involving seven enrichment treatments, NAP increased with increasing CO2 between ambient (1.0x) and s.5x CO2 concentrations. In growth experiments, mean growth rate of Zostera increased with increasing CO2 during one of the two trials. I conclude that increased CO2 in the surface waters of the coastal ocean would predictably result in increased NAP of these two species. These results supplement limited published data showing that shallow estuarine and marine systems are vulnerable to increased carbon dioxide.

Keywords: marine mammals//oil spills
Abstract: The Exxon Valdez ran aground on Bligh Reef, Prince William Sound, Alaska on March 24, 1989, spilling millions of gallons of Prudhoe Bay crude oil (PBCO). During the weeks following the spill, large amounts of oil flowed towards southwestern Prince William Sound, and as a result, many shorelines were oiled. The spreading of spilled oil raised concerns on the part of native Alaskan that subsistence seafoods (fish, marine mammals, and invertebrate organisms) were contaminated by the spilled petroleum. At the request of native Alaskans, a study was conducted as a cooperative effort among NOAA, Exxon, and the Alaska Department of Fish and Game to assess the degree of contamination of subsistence organisms by PBCO. In this study, edible flesh of fish, marine mammals, and shellfish from 22 native subsistence food collection areas and from two reference areas (Angoon and Yakutat) were analyzed for aromatic compounds (AC's). The results to date provide important information on the level of contamination of subsistence fish, shellfish, and marine mammals from fishing areas of native Alaskan villages in and near Prince William Sound. In an advisory opinion, the Food and Drug Administration has indicated that little risk is involved in the consumption of the nonsmoked subsistence foods studied. Subsistence food gatherers were advised not to collect or consume food if oil was observed to be present. The results also show that in future oil spills, shellfish tissues should be given the highest priority for analysis, whereas rapid screening of bile from fish and marine mammals should be sufficient to provide information on the level of exposure.

Keywords: MPA//marines reserves//trophic ecology
Abstract: The growing disillusion with the predictive capability of single species assessment methods and the realization that the management approaches they imply will always fail to protect bycatch species has led to growing interest in the potential of marine protected areas (MPA's) as a tool for protecting such species, and allowing for rebuilding populations of target species and damaged habitat. Evaluating MPA's abilities to meet these requirements will demand both field experiments and simulations. However the tools required for the latter need not be as detailed as is often thought, and particularly, need not include detailed links between resource species and physical processes. Ecospace is a spatially explicit model for policy evaluation which allows considering the impact of MPAs in an ecosystem (i.e., trophic) context, and relies on the Ecopath mass-balance approach for most of its parameterization. Additional inputs are movement rates, used to compute exchanges between grid cells, the settings (top- down vs. bottom up control) also required for Ecosim, the dynamic simulation routine derived from the system of linear equations in Ecopath, and habitat preferences for each of the functional groups included in the model. Convergence from the homogenous distribution assumed in the Ecopath base model to highly patterned distributions, simultaneously accounting for the habitat preference and food requirements of predators and preys, the distribution of fishing effort (driven by local abundances and fishing costs) and the existence of MPA's is extremely rapid. This is due to an integration scheme with different step sizes for the 'fast' and `slow' groups, allowing the former to track the population changes of the latter. Color figures documenting the ability of Ecospace to generate realistic spatial distributions of functional pools, under constraints of habitat preference, distribution of fishing effort, etc. may be accessed from the publications section on the Ecopath home page (www.ecopath.org.), from which the software itself may also be downloaded. `Cascade' effects, wherein prey organisms are low where predators are abundant, e.g. in areas onto which high fishing costs have been mapped, or in MPAs are discussed. It is then shown that the potential benefits of local effort reductions can be easily negated by high movement rates, and especially by the concentration of fishing effort at the edge of the MPA's, where cascade effects generate prey gradients attracting predators out of the protected areas. Despite various limitations (e.g. no explicit consideration of seasonal changes or directed migration), the outward simplicity of Ecospace, and the information-rich graphs it generates, coupled with the increasingly global availability of the required Ecopath files, potentially ensure a wide use for this approach. This will be of use for both generating hypotheses about ecosystem function and for evaluating policy choices.

Keywords: harvesting practices//harvest//benthos//benthos impacts//commercial fishery//harvest
Abstract: Bottom trawling and use of other mobile fishing gear have effects on the seabed that resemble forest clearcutting, a terrestrial disturbance recognized as a major threat to biological diversity and economic sustainability. Structures in marine benthic communities are generally much smaller than those in forests, but structural complexity is no less important to their biodiversity. Use of mobile fishing gear crushes, buries, and exposes marine animals and structures on and in the substratum, sharply reducing structural diversity. Its severity is roughly comparable to other natural and anthropogenic marine disturbances. It also alters biogeochemical cycles, perhaps even globally. Recovery after disturbance is often slow because recruitment is patchy and growth to maturity takes years, decades, or more for some structure-forming species. Trawling and dredging are especially problematic where the return interval--the time from one dredging or trawling event to the next--is shorter than the time it takes for the ecosystem to recover; extensive areas can be trawled 100-700% per year or more. The effects of mobile fishing gear on biodiversity are most severe where natural disturbance is least prevalent, particularly on the outer continental shelf and slope, where storm-wave damage is negligible and biological processes, including growth, tend to be slow. Recent advances in fishing technology (e.g., rockhopper gear, global positioning systems, fish finders) have all but eliminated what were de facto refuges from trawling. The frequency of trawling (in percentage of the continental shelf trawled per year) is orders of magnitude higher than other severe seabed disturbances, annually covering an area equivalent to perhaps half of the world's continental shelf, or 150 times the land area that is clearcut yearly. Mobile fishing gear can have large and long-lasting effects on benthic communities, including young stages of commercially important fishes, although some species benefit when structural complexity is reduced. These findings are crucial for implementation of "Essential Fish Habitat" provisions of the U.S. Magnuson-Stevens Fishery Conservation and Management Act which aim to protect nursery and feeding habitat for commercial fishes. Using a precautionary approach to management, modifying fishing methods, and creating refuges free of mobile fishing gear are ways to reduce effects on biological diversity and commercial fish habitat.

Abstract: This report describes seven indigenous salmon and trout of the genus Oncorhynchus in Washington and Oregon (chinook, coho, chum, sockeye, and pink salmon, and steelhead and cutthroat trout), for this paper we will collectively call them salmon. Their habitat extends from the smallest inland streams to the vast North Pacific Ocean, an area of freshwater, estuarine, and ocean habitats in excess of 4 million km2. Due to past commercial fisheries, habitat loss, hatchery problems, and more recently a changing ocean environment, salmon populations have shown substantial decline over the past several decades. Many salmon stocks in Washington and Oregon are now listed as either threatened or endangered, under the Federal Endangered Species Act.
Early in this century and up until relatively recently, commercial fishing permanently diverted massive quantities of nutrients away from Washington and Oregon rivers, and their respective fish and wildlife inhabitants. Recent calculations indicate that only 3 percent of the marine-derived biomass once delivered by anadromous salmon to the rivers of Puget Sound, the Washington Coast, Columbia River, and the Oregon Coast currently reaches those streams. There have also been many other losses of salmon habitat during this period caused by: river channel clearing and channelization; log driving and splash damming; extensive land clearing; major water diversions; livestock grazing; mining runoff pollution; logging road associated erosion and removal of the old growth forest; filling and diking of wetlands and estuaries; hydroelectric dam development; urban runoff; water and sediment contamination with toxicant, and recently recognized human induced oligotrophication of waterways. Over fishing and habitat degradation, together with a background of a changing ocean environment, have cumulatively reduced stock resilience. A century of hatchery programs have failed to rebuild the wild runs, and in many cases, likely contributed to their further declines. Modern salmon management techniques have become highly sophisticated, however, they have not been able to keep pace with the salmon population declines.

Keywords: salmon//fish//water quality//contaminants//human impacts
Abstract: Tolerance to environmental change depends, at least in part, on the individual fish's ability to regulate stabilizing processes that will effect the required physiological or behavioral adaptation. An understanding of the stress response, and the environmental alterations to which fishes can adapt through this response, is important to a definition of the limits of change in the aquatic environment that can be tolerated. Although most species can tolerate relatively severe stress for limited periods due to their homeostatic capabilities, these should not be used as an excuse for allowing marginal conditions to occur in the aquatic environment. Instead, these capabilities should be used to set priorities and limits for species-habitat relationships so that environmental alterations can be correctly evaluated in terms of their biological costs or benefits. This monograph discusses concepts and methods for developing the improved species-habitat database required to correctly evaluate the tolerance limits of fish and fish populations to single and multiple environmental stress factors.

Keywords: rockfish//fish//Puget Sound
Abstract: In this study, patterns were compared of settlement, recruitment, abundance, growth, and habitat associations of juveniles of a guild of three strongly substrate-associated rockfishes-copper (S.caurinus), quillback (S. maliger), and brown rockfish (S. auriculatus)--on two types of artificial nursery habitat. One type of reef was designed to provide refuge habitat for small, juvenile forms only, and the other to provide habitat for adults as well as juveniles. We tested functional differences of the reefs in terms of densities of juvenile rockfish they supported without attempting to separate specific effects attributable to differential predation or habitat quality. This study suggests that existing artificial reef systems targeting Sebastes spp. can be more finely tuned by providing refuge and foraging habitat for the complete demersal phase of target species.

Abstract: This report submitted to the Washington State Legislature, summarizes the history of the Puget Sound Oyster Reserves and identifies 4,500 acres as originally included in the reserve system with all but 1,000 acres of the least productive ground having been sold to private growers. Out of 1,003 acres of reserves, 21 acres are prime clam producing areas with three tracts suitable for Olympia oyster enhancement, five for shellfish produciton and two for long-term lease. This report identifies those tracts suitable for public recreation, clam enhancement, for private leases, or tracts considered unproductive for clams or oysters.

Keywords: fish//cod//straits
Abstract: Four important stocks of Pacific cod (Gadus macrocephalus ) were delineated in the straits, primarily based on results of extensive Canadian and U.S. tagging experiments during 1954-79. All four stocks were exploited seasonally, almost exclusively by on-bottom trawls. Two stocks were resident year-round (MSA 14 and Gulf Islands), and two were itinerant and seasonal (Nanoose and MSA 19). Standardized landing statistics and landings-at-age were employed to assess each stock. Yield-per-recruit (YPR) analysis indicated that maximizing YPR was impractical because the required mesh size was too large for the mixed-species fishery. Current legal, minimum mesh (4.25", synthetic materials) was satisfactory for maximizing catch profitability (YPR/F).

Abstract: This report reviews the geology, climate and hydrology determining habitat types and functions. It reviews habitat losses in streams and wetlands along with loss of river deltas for the Nooksack, Lummi, Snohomish and Puyallup Rivers. It reviews the status of introduced species such as spartina, zostera japonica and sargassum and reviews shoreline armoring trends Thurston County. Toxic contaminants threaten water column and benthic habitatas. Point source discharges of toxic materials include sewage treatment plants and industrial facilities discharging to rivers and the Sound. Stormwater runoff is an important source of toxic pollution carrying pesticides, PAH's and other toxins. Stormwater toxic load is believed significant. Puget Sound populations have grown from 1 million in 1950 to 4 million in 2000 and an expected 4.5 million in 2010. Human population growth presents a very large challenge to biological integrity in marine waters.

Keywords: buoys//moorings//eelgrass/human impacts
Abstract: STUDY OBJECTIVES: Observe different mooring buoy installations in the San Juan Islands and their impact on eelgrass and macroalgae habitats. METHODS: SCUBA survey of sixty five different mooring buoy installations representing different current regimes, prevailing wind/wave patterns and water depths throughout the San Juan area over a two day period in August of 1996. RESULTS: Buoy designs were grouped into six different design categories: 1) mid line float, 2) all rope lines, 3) rope to chain lines, 4) all chain lines, 5) other (i.e. stainless cable, steel rods, tires etc.), and 6) mid line float with counterweight. Properly installed midline float systems demonstrated the least impact to marine vegetation with the mid line float preventing the anchor to surface line from contacting the bed. The all rope designs demonstrated minor impacts to marine vegetation with only 14% disturbing marine vegetation. The weight and diameter of lines used and growth on the lines determines its success in preventing disturbance. Eighty six percent of the rope to chain design disturbed marine vegetation with the magnitude of impact depending upon chain size and weight of rope material. Mid-line float with counterweight appeared to have the potential for significant impacts to vegetation given current, tidal height, wind, and wave regimes. Low tide cycles offer the greatest opportunity for contact with marine vegetation with disturbance usually resulting from the anchor to surface line contacting the bed during low tides. Mooring buoys located in higher current areas have a greater potential for disturbing marine vegetation than those in sheltered bays. Buoys in areas with prevailing wind/wave patterns that counteract current regimes tend to show a "v" shaped disturbance impact on vegetation. Vegetation types were Z. marina, ulva and laminaria. Laminaria may be more resistance to disturbances than eelgrass or ulva. This may be due to its laying prone to the bed rather than vertical in the water column. CONCLUSIONS: Marine vegetation is shown to be impacted by a single mooring surface line scouring the bed. The cumulative impact of mooring buoy installations in our marine waters is probably significant. Mooring buoy installation design, tides, water, depths, water currents, prevailing wind/wave patterns, and marine vegetation type are variables that determine the shape and extent of the disturbance. Moorings using designs 1 and 2 demonstrated little or no impact where 93% of designs 3, 4, and 5 demonstrated impacts. Design 6 appears to have the greatest potential for significant marine vegetation impact if improperly installed. The effectiveness of designs 1 and 2 rely on using the proper rope lengths relative to maximum water depth, sizes and types of rope used.

Wilson, Ulrich W. and J. B. Atkinson. Black Brant winter and spring staging use at two Washington coastal areas in relation to eelgrass abundance. The Condor. 97(1):91-98.
Keywords: birds//straits//eelgrass//nearshore/
Abstract: We monitored numbers of black Brant (Branta bernicla nigricans) in Washington from fall 1980 through spring 1992 at Willapa Bay, and from fall 1986 through spring 1993 in the Dungeness area. We estimated brant use by converting the counts into use days. Coincidentally, we also monitored variation in the extent of eelgrass (Zostera marina) beds by remote sensing techniques. At Willapa, brant use was positively correlated with the total extent of eelgrass beds and negatively correlated with the extent of oyster beds that were located within eelgrass beds, and where eelgrass had been removed by mechanical means. A 52% decline in brant use was associated with a 22% decline in eelgrass. At Dungeness, there was a significant negative trend in spring-staging brant use. Overall, a 63% decline in brant use coincided with a 31% decline in eelgrass. The Dungeness eelgrass beds may have declined because of natural factors. In both areas, brant use during the spring-staging period was more related to eelgrass extent than brant use during the winter months. These results suggest that Black Brant use in coastal Washington is limited by eelgrass availability. Immatures averaged 10.4% of the population at Willapa and 9.9% at Dungeness and are amongst the lowest reported. A shortage of eelgrass during the critical spring-staging period may have led to reduced endogenous reserves and associated low reproductive success of Black Brant that staged in coastal Washington. The shortage of eelgrass may have contributed to the observed southward shift to Mexico by wintering brant.

Keywords: fish//nearshore//Puget Sound//bottomfish//groundfish
Abstract: This study, at three sites in central Puget Sound, provided extensive documentation on the seasonal occurrence abundance, and distribution of many nearshore and demersal fishes. In addition, the dominant nearshore and demersal species assemblages which occurred at the study sites were determined in an effort to: 1) better understand the ecological relationships among the fishes which compose nearshore and demersal species assemblages, 2) predict the possible effects of chronic or catastrophic pollution on the nearshore environment, and 3) determine the food web pathways through which pollutants introduced to the marine environment might be transferred to humans. This report summarizes: 1) the food habits of most ecologically important nearshore and demersal fishes in central Puget Sound, 2) the life history stage and seasonal changes in dietary composition for the most abundant species, and 3) preliminary food webs for the important nearshore and demersal fishes.

Keywords: MPA//marine reserves//marine protected areas
Abstract: Social aspects in relation to the establishment of marine reserves have received little attention compared with the study of bio-physical phenomena. Subsequent to the passing of the Marine Reserves Act (1971), New Zealand led the world in protection of the marine environment with an area of non-extraction at Goat Island, Leigh. During the intervening years, no additional mainland marine reserves were created until the designation of Cathedral Cove marine reserve in1993. The present study examined the nature of community reactions to marine reserve proposals. Beliefs, attitudes and knowledge regarding marine reserves were explored and related to the stance of the respondent (i.e. supporting or opposing a proposal for a marine reserve in their vicinity). Sample populations of 200 rate-payers from four target areas (two high-impact and two low-impact control areas) participated in a questionnaire study. Results confirmed the hypotheses that the establishment of marine reserves would be supported by the majority of respondents, dependent on the implementation of comprehensive social and environmental impact assessments, resulting in the identification of appropriate sites. Public involvement in the planning process, concomitant with information, communication, and compromise were identified as
strategies to reduce intergroup conflict. The findings of the present research have implications for legislation, implementation, policy-making, management and public relations relevant to the establishment of marine reserves.

Abstract: Reports on findings of chlorinated dioxins and furans that bioaccumulate in human and animal tissue. This dioxin source assessment sought to summarize what is known about dioxin sources in Washington State and recommend actions. Potential sources of dioxin include contaminated sites. For the purposes of this report, a "source category" is defined as a group of sources engaging in a similar process (e.g. incineration or wood-treating with pentachlorophenol). Wood treating, municipal and medical waste incinerators. bleached pulp process, cement kilns, hog-fuel boilers and structure fires are examples of sources. Municipal wastewater treatment plants can pass on dioxins in discharge from sources discharged to the plant. The report reviews the structure of such chemicals and into incorporation in the human and animal food web. Port Townsend Paper Corp. is listed as a hog fuel burning facility.

Abstract: This paper describes the methods
used to monitor the response of rockfishes to no-take refuges in Puget
Sound. Differences in density, size and reproductive output between fished
rock areas and no-take refuges were compared. These results confirm size
truncation, decreased population abundance, and a reproductive potential
that is less than 10% that of historical levels for heavily fished rockfishes.
High site fidelity and small home ranges make copper, quillback and brown
rockfishes suitable candidates for a no-take refuge management regime.
This paper discusses techniques and methods used to monitor rockfish and
other fish populations in no-take refuges.
