Download or read book A Comprehensive Review of Chilkat Lake and River Sockeye Salmon Stock Assessment Studies written by Julie Bednarski and published by . This book was released on 2017 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1967 the Alaska Department of Fish and Game, Division of Commercial Fisheries, has operated a stock assessment program to estimate escapements and harvests of Chilkat sockeye salmon (Oncorhynchus nerka). Sockeye salmon were counted through a weir near the outlet of Chilkat Lake, and age, length, and sex data were collected and analyzed each year. Since 1994, mark-recapture studies were conducted to estimate Chilkat sockeye salmon escapements. Since the start of the 2008 season, DIDSON sonar has been used at the weir site to directly enumerate adult sockeye salmon escapement into Chilkat Lake. Visual scale pattern analysis was conducted to determine the proportion of Chilkat sockeye salmon harvested annually in the District 15 commercial drift gillnet fishery. In addition, limnological sampling was conducted in Chilkat Lake and analyzed each year. The intent of this report was to review Chilkat sockeye salmon stock assessment data from 1971 to 2016. The visual and DIDSON weir counts provide an index of escapement; however concerns regarding mark-recapture as a reliable index of abundance lead us to recommend eliminating mark-recapture studies in 2017 and, instead, maintain the DIDSON to estimate escapement into Chilkat Lake. We also recommend reviewing the current Chilkat Lake biological escapement goal to ensure that the goal and escapement estimates are in the same units, which is currently based on mark-recapture units. An average of 77,800 Chilkat Lake sockeye salmon were harvested annually in the District 15 commercial drift gillnet fishery (1976-2016). A comparison of historical fish wheel counts to Chilkat Lake escapement estimates demonstrates that the fish wheel project provides a rough indication of Chilkat Lake run strength. Zooplankton samples from Chilkat Lake were composed primarily of one species of copepod (Cyclops columbianus) and three species of cladocerans (Bosmina longerostris, Daphnia longiremus, and Daphnia rosea).

Download or read book Stikine River Sockeye Salmon Stock Assessment, 2021 written by Julie Bednarski and published by . This book was released on 2021 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2021 forecast of Stikine River sockeye salmon, Oncorhynchus nerka, run abundance is poor and we anticipate very little harvesting opportunity for either U.S. or Canadian fisheries. Since 1994, we have almost exclusively relied on the Canadian lower river commercial fishery to provide the migratory timing information that is used to complete the mixed stock run reconstruction for Stikine River sockeye salmon. It is highly likely there will be no fishing opportunity in 2021 to gather this pertinent information. To obtain stock composition data necessary to estimate the inriver abundance, we are initiating a sockeye salmon stock assessment program at Kakwan Point. The project will be conducted in conjunction with the existing Stikine River Chinook salmon, O. tshwaytscha, assessment program, and will extend the project through the end of the sockeye salmon run in late August. Tissue samples will be collected from sockeye salmon for genetic mixed stock analysis and for use in a genetic mark–recapture study to estimate inriver abundance based on an expansion of the Tahltan stock that is monitored via weir. We will also gather daily catch per unit effort (CPUE) information and estimate the age, sex and length (ASL) composition for sockeye salmon captured. This stock assessment program is designed to capture sockeye salmon in proportion to abundance during immigration; therefore, it is expected that it will provide an unbiased estimate of abundance. This estimate will be assessed by TTC postseason for use in the Stikine River sockeye salmon run reconstruction.

Book excerpt: The Chilkoot Lake sockeye salmon (Oncorhynchus nerka) run, which spawns near Haines, is one of the largest in Southeast Alaska and contributes substantially to harvests in the District 15 commercial drift gillnet fishery in Lynn Canal. This operational plan outlines objectives, methods, and timelines for conducting sockeye salmon stock assessment designed to (1) estimate annual escapement and harvest, (2) provide information for inseason fishery management, and (3) reconstruct runs and assess stock status. The Chilkoot Lake run is managed for a biological escapement goal of 38,000–86,000 fish, which is enumerated through a standard picket weir located just downstream of the lake outlet. Weir counts of sockeye salmon are compared to weekly escapement targets to determine inseason run strength. Genetic mixed stock analysis of weekly sockeye salmon harvests in the District 15 commercial drift gillnet fishery provides stock composition estimates that also guide inseason management of the fishery. Biological sampling, along with escapement enumeration and stock-specific harvest data, allows for total run reconstruction required for escapement goal review.

Available in PDF, EPUB and Kindle. Book excerpt: In 2020 and 2021, the Alaska Department of Fish and Game, Division of Commercial Fisheries, continued a stock assessment program that began in 1976 to estimate escapements and harvests of Chilkoot Lake sockeye salmon (Oncorhynchus nerka). Sockeye salmon were counted through a weir near the outlet of Chilkoot Lake, and age, length, and sex data were collected and analyzed each year. Sockeye salmon escapements at the weir were 60,218 fish in 2020 and 98,672 fish in 2021, which fell within or exceeded the sustainable escapement goal range of 38,000–86,000 fish. Age-1.2 male sockeye salmon in 2020 were larger than the 1982–2019 average, whereas both male and female fish of other ages fell below this average. Genetic stock identification was conducted to determine the stock composition of sockeye salmon harvested annually in the District 15 commercial drift gillnet fishery. Estimated commercial harvests of Chilkoot Lake sockeye salmon were 24,878 fish in 2020, and 50,219 fish in 2021. Estimated harvest rates (including subsistence and excluding sport harvests) were 32% in 2020 and 35% in 2021, and Chilkoot Lake sockeye salmon accounted for an estimated 50% (2020) and 59% (2021) of the annual commercial sockeye salmon harvest in District 15. The estimated fall sockeye salmon fry population at Chilkoot Lake was 66% below average in 2020 (no surveys were conducted in 2021). Average May–September zooplankton density and biomass at Chilkoot Lake were above average in 2020 and below average in 2021.

Download or read book Stock Assessment and Restoration of the Afognak Lake Sockeye Salmon Run, 2009 written by Robert T. Baer and published by . This book was released on 2010 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Afognak Lake sockeye salmon Oncorhynchus nerka run severely declined in 2001 and has remained low since. Concerns expressed by local subsistence users to the Alaska Department of Fish and Game and the US Fish and Wildlife Service Office of Subsistence Management prompted an investigation of the lake's rearing environment in 2003 followed by subsequent annual studies. This report provides 2009 project results, a summary of results from 2007 and 2008, and an evaluation of limnology conditions and their effects upon smolt production.
