NOAA Fisheries is a cooperator with the Washington Department of Fish and Wildlife and the Lummi, Nooksack, and Stillaguamish Tribes in a 10-year program to rebuild the South Fork Nooksack River spring Chinook and Stillaguamish River fall Chinook stocks through a captive broodstock program. Information on the number of juveniles received into the program is maintained and summarized by year. The production of prespawning adults transferred to Tribal Facilities for spawning is also annually summarized.

Puget Sound and the Northwest Straits have experienced a long history of commercial fishing activity. Although much of this fishing activity no longer takes place, there remains lost and abandoned fishing gear throughout Puget Sound and the Northwest Straits. Derelict gear has the potential to impact marine fauna through entanglement and trapping. Collaborative work of federal, state and tribal agencies with local and regional non-governmental agencies, specifically the Northwest Straits Foundation, has recovered thousands of derelict nets and pots since 2002 and documented their impacts on marine fauna, many of which are of commercial and/or conservation concern. Marine fauna.

Gene rescue captive broodstock program was established for ESA-listed endangered Snake River sockeye salmon from Redfish Lake, Idaho. The program has consisted of taking most of the remaining gene pool into captive culture at specialized conservation hatcheries at the Manchester Research Station and the Idaho Department of Fish and Game Eagle Hatchery. Fish are being released to native habitats as part of recovery efforts. Raw data on rearing density, loading density, water temperature, ration, and feed size may be available. Raw data on administration of therapeutic drugs may be available.

As part of a long-term contaminant-monitoring program of fish in Puget Sound and Georgia Basin, Washington Department of Fish and Wildlife (WDFW) and NWFSC have collaborated in collection and analyses of fish and other marine biota to determine contaminant exposure and potential effects to a wide range of marine species. NWFSC staff help collect samples and conduct chemical tracer analyses of a number of marine organisms to provide information about spatial and temporal changes in contaminant and lipid levels, as well as provide information on their potential health effects. WDFW takes the lead on study design and sample collection and provide expertise in the distribution and ecology of the fishes. This information can then be used by agency management to make informed decisions about Puget Sound/Georgia Basin fishery resources and habitats. In FY18-19, the NWFSC will analyze approximately 500 tissue/fluid samples of marine and anadromous fish species and the associated quality assurance samples for chemical contaminants (e.g., persistent organic pollutants, polycyclic aromatic hydrocarbons (PAHs), PAH metabolites, xenoestrogens), as well as percent solids and lipids. In addition, approximately 20 semi-permeable membranes and the associated quality assurance samples will be analyzed for this same suite of chemical contaminants. Determining levels of persistent organic pollutants, polycyclic aromatic hydrocarbons and xenoestrogens in various matrices of fish from Puget Sound.

This project has two objectives: 1. Estimate the amount of rearing habitat available to juvenile Chinook salmon currently and historically (i.e., ~1850s) throughout the Puget Sound region 2. Estimate the carrying capacity of the habitat in the region to support juvenile Chinook under current and historical conditions. Krista Bartz is the principal investigator for the project, and most of the analytical work is complete (as of May 2012). The remaining work involves completing a manuscript describing the work. Specific product for this project is a manuscript (likely the North American Journal of Fisheries Management). Audience for the project was initially intended to be NWFSC staff involved in parameterizing a Puget Sound-wide life-cycle model for Chinook salmon. Since ~2008, when that effort stalled, there has been a resurgence in interest in developing such a model. This is a one-time, stand-alone with soft deadlines in October 2012 to send the manuscript for internal review and December 2012 to send the manuscript to the journal. Estimates of changes in Chinook salmon juvenile rearing capacity in rivers and estuaries throughout Puget Sound, using pre-settlement conditions as the baseline.

In the early 1990s, Redfish Lake sockeye salmon from the Sawtooth Basin in Idaho were on the brink of extinction, and they were listed as endangered under the US Endangered Species Act in 1991. To prevent extinction, a gene rescue captive broodstock program was established for the stock that consisted of taking most of the remaining gene pool into captive culture at specialized conservation hatcheries at the Manchester Research Station and the Idaho Department of Fish and Game Eagle Hatchery. Efforts through the decade of the 1990s consisted of developing techniques for successful culture of sockeye salmon to adulthood, establishing rearing and spawning protocols to ensure preservation of stock diversity, and habitat enhancement at the rearing lakes. In the early 2000s, the program began to include a demographic focus to boost the population through rearing and release of enough juveniles to produce some adult returns. For the last few years, NWFSC eyed egg production has resulted in over 150,000 smolts being released into the Stanley basin annually for recovery, with plans to increase NWFSC eyed egg production to support release of half a million smolts in the Stanley Basin by 2017. In 2011, and for the fourth year in a row, record numbers of sockeye adults have returned to their native home in Idaho. All fresh mortalities larger than 100 mm are sent to Fish Health for pathology. Autopsy data is maintained on their database.

The production of adults spawned, adults transferred to Idaho for release, green eggs taken, and eyed eggs shipped to Idaho and Oregon facilities for restoration activities is also annually summarized.

The fork length to the nearest mm, weight to the nearest gram, fecundity, and green egg weight to the nearest mg of every female spawned is recorded. The fork length to the nearest mm, weight to the nearest gram, milt weight to the nearest 0.01 gram, milt volume, spermatocrit, and milt motility of every male spawned is recorded. The eyed egg weight and % survival to the eyed stage for every batch of fertilized eggs is recorded. A record is maintained describing which male is crossed with which female.
