Contaminants in SRKWs


Sandra O’Neill, Contaminants in salmon We’ve heard that S and N residents are both eating mostly Chinook.  Why are the southern residents more contaminated than the northern residents? Contaminants in fish are determined by: where they live what they eat how long they are exposed how fat they are Chinook and Coho have elevated [PBDE] [...]

Prey relationship talks


8:35 John Ford, resident KW foraging ecology What may have caused the simultaneous declines in the N and S residents during the late 1990s?  Nutritional stress? We compared expected and observed births and deaths, where expectations were based on period of unlimited growth (’73-’90).  There were two phases of increased mortality in adult/juvenile fe/males: late [...]

Juvenile Salmon Use of Nearshore Habitats in San Juan County


Tina Wyllie-Echeverria Collaboration with Eric Beamer and Kurt Fresh (tows), and many students/volunteers 1950-2006, about 50 sites around the San Juans have been sampled and have found juvenile salmon.  Of 656km of SJI shoreline, 430km is rocky beach.  Tow nets (164 tows at 37 sites, monthly from Apr-Sep) caught juveniles of 5 species and 785k [...]

Nearshore Chinook use in Strait of Juan de Fuca


Anne Shaffer Focus on central and western strait, trying to identify restoration actions associated with dam removal on the Elwha.   The area is also an important migratory corridor, ultimately seeing about 85% of the outflow from the Salish Sea.  430 seines in many habitat types over last 18 months, 16 snorkel surveys, 2 yrs surf [...]

Fish Response to Shoreline Habitats


Jason Toft Comparing along-shore snorkel surveys between cobble beach, sand beach, rip rap, deep rip rap, and overwater structure. We see biggest difference when you have sub-tidal modifications. Gastric lavage of juvenile Chinook: insects dominate in shallow habitats, plankton/benthic dominate when shoreline is steep. At Olympic sculpture park, we looked at pocket beach and subtidal [...]

Juvenile Chinook use pocket estuaries near natal rivers


Eric Beamer, Juvenile Chinook salmon use of small non-natal estuaries  in the Whidbey Basin, eastern Admiralty Inlet, and the San Juan Islands Most of our juveniles are coming from the Skagit, accumulating early in the year (feb-may, some years as early as december, often associated with floods).  Pocket estuaries are safer places (most fish are [...]

North Kitsap Nearshore Fish


Paul Dorn, Preliminary Results of Beach Seine Sampling in 2007 and 2008. Unmarked coho dominated our seines, particularly in may/june.  Coho size about 120-140cm, larger if from hatchery.  Lots of juvenile chum in apr/may/june (many more in 2007 than in 2008, probably due to Dec 07 floods).  2008 pink salmon (may/june) show this is part [...]

Nearshore distribution and size-structure of juvenile salmon and forage fishfrom the observations and modeling on watersheds, marine waters, and marine biota. These talks will focus


Elisabeth Duffy*, David Beauchamp Juvenile salmon are moving through Puget Sound (PS) from April-July.  By end of July most have made it to the deep ocean.  Percent of fish from hatcheries is about 50% in N PS and 90% in S PS. Nearshore fish comunity: herring and perch up north, hatchery salmon dominate in the [...]

Forage fish spawning habitat selection


Theresa Liedtke et al focuesd on 2 forage fish species: Pacific sand lance and Pacific herring Initially focused on Liberty Bay (Poulsbo, WA; today’s data) with non/urban coastline; now working at Possession Point (s Whidbey Island) to get higher wave action and feeder bluffs.  12 sand/sediment samples, 500ml samples preserved eggs. Findings: 40k eggs in [...]
