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.

Download or read book Afognak Lake Sockeye Salmon Stock Monitoring Project Operational Plan, 2023-2025 written by Darin Ruhl and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This operational plan provides the instruction and procedures to properly operate the Afognak Lake adult salmon escapement weir and successfully meet each project objective. The primary function of maintaining a weir at Afognak River is to enumerate sockeye salmon Oncorhynchus nerka returning to Afognak Lake for the Alaska Department of Fish and Game (ADF&G) management of the Afognak Bay commercial, subsistence, and sport fishery. All fish passing upstream or downstream through the weir are identified, enumerated, and reported to the ADF&G office in Kodiak daily. Enumeration at the weir serves a secondary purpose by providing run timing and escapement information for Kodiak Regional Aquaculture Association (KRAA), which uses Afognak Lake sockeye salmon as an early-run brood stock source for various enhancement projects on Kodiak Island. Project activities at Afognak River weir include installation, operation, and maintenance of the weir, salmonid enumeration, record daily physical weather observation, and the collection of age, sex, and length (ASL) samples and corresponding data."--Page 1

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A weir will be used on the Buskin River to count the inriver coho salmon run, with harvest estimated by the Alaska Department of Fish and Game statewide harvest survey, returned subsistence permits, and commercial fish tickets. Age and sex information will be collected from the Buskin River coho salmon run, and the composition of the run by age and sex will be estimated. In addition, coho salmon escapements to 9 other drainages on the Kodiak road system (KRS) will also be indexed. Sustainable escapement goals (SEGs) associated with the American, Olds, and Pasagshak Rivers will be monitored via postseason escapement foot surveys. A simultaneous postseason drone survey will also be conducted on the American and Olds Rivers to continue exploring establishment of drone-based SEGs. Multiple inseason surveys will be conducted by drone at each of the Olds, American, and Pasagshak river drainages to provide inseason run information to fishery managers; the inseason data will also be used to explore new ways of establishing SEGs for the Pasagshak River. Postseason escapement foot surveys will be conducted for the remaining 6 KRS rivers without SEGs (Monashka Creek, Pillar Creek, Sargent Creek, Russian Creek, Salonie Creek, and Roslyn River). The Pasagshak River coho salmon escapement will also be estimated with a temporally stratified mark–recapture study.

This operational plan outlines objectives, methods, and timelines for conducting sockeye salmon stock assessment designed to (1) estimate annual escapement, (2) provide information for inseason fishery management, and (3) reconstruct runs and assess stock status. The Chilkat Lake sockeye salmon run is managed for a biological escapement goal of 70,000–150,000 fish, which is enumerated with a Dual-Frequency Identification Sonar (DIDSON) system operated in conjunction with a standard picket weir located just downstream of the lake outlet. Genetic mixed stock analysis of weekly sockeye salmon harvests in the District 15 commercial drift gillnet fishery provides stock composition estimates that guide inseason management of the fishery (detailed in a separate Chilkoot Lake sockeye salmon operational plan). Biological sampling, along with escapement enumeration and stock-specific harvest data, allows for total run reconstruction required for escapement goal review. This project also supports the collection of basic limnology information at Chilkat Lake.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Russian River sockeye salmon escapement assessment project, which began in 1962, is one of the oldest stock assessment projects in the state of Alaska. During 2023–2026, the Russian River weir will be operated annually from early June through the first 7 to 10 days of September. All species of fish seen passing the weir through the fish chute will be enumerated daily. Sampling of sockeye salmon for age, sex, and length data will be done each Friday, and the sample size each week will be based on the previous week’s fish passage. Sockeye and Chinook salmon spawning downstream of the Russian River weir to the confluence of the Russian River and the Kenai River will be assessed by a foot survey during the fourth week of August. Multiple foot surveys will also be conducted from mid-May to 10 June to assess spawning rainbow trout.
Book Synopsis Inriver Abundance of Stikine River Sockeye Salmon, 2022-2024 by : Kristin Courtney
Download or read book Inriver Abundance of Stikine River Sockeye Salmon, 2022-2024 written by Kristin Courtney and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2022 forecast of Stikine River sockeye salmon, Oncorhynchus nerka, run abundance is poor and we anticipate very little harvest 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 stock-specific information that is used to complete the mixed stock run reconstruction for Stikine River sockeye salmon. It is highly likely there will be little commercial fishing opportunity in 2022 to gather this pertinent information. To obtain stock composition data necessary to estimate the inriver abundance, we will continue to conduct a sockeye salmon stock assessment program at Kakwan Point that began in 2021. The project will be conducted in conjunction with the existing Stikine River Chinook salmon, O. tshwaytscha, stock assessment program, and will extend the project through the end of the sockeye salmon run in mid-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 CPUE information, capture and spaghetti tag sockeye salmon, and estimate the age, sex, and length composition for sockeye salmon captured at Kakwan Point.

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: This multi-year project will provide current, area-specifc migration and run timing information for stocked McDonald Lake fish to supplement recent genetic stock identification studies and help determine if fishery closures outlined in the McDonald Lake action plan (Bergmann et al. 2009) are effective at reducing harvest on this stock as intended.
Book Synopsis Lower Cook Inlet Remote Video Salmon Escapement Monitoring Operational Plan, 2023 by : Edward O. Otis
Download or read book Lower Cook Inlet Remote Video Salmon Escapement Monitoring Operational Plan, 2023 written by Edward O. Otis and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall purpose of this project is to provide information on the run-timing and magnitude of sockeye salmon Oncorhynchus nerka escapements to Mikfik and Chenik lakes in the Kamishak District of the Lower Cook Inlet Management Area (LCIMA). Results will be used by Alaska Department of Fish and Game (ADF&G) fisheries managers to facilitate informed inseason management of commercial purse seine fisheries targeting these stocks to be consistent with sustained yield of wild stocks (AS 16.05.730), follow appropriate principles and criteria in the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222), and achieve spawning escapement goals (5 AAC 39.223). This plan documents procedures we developed for estimating sockeye salmon escapement using an unmanned, or autonomous video counting tower (AVCT) that employs above-stream remote video cameras and digital time-lapse recording equipment (Otis and Dickson 2002). Hard drives are retrieved regularly, and video reviewed immediately so managers can use these data to adjust fishery openings in season to attain established escapement goals (Hollowell et al. 2022). The annual escapement indices derived by remote video are also used to refine the sustainable escapement goals for these stocks, currently established by ADF&G at 3,400–11,000 for Mikfik Lake and 2,900–13,700 for Chenik Lake (Table 1; Otis et al. 2010, Otis et al. 2013, Otis et al. 2016).

Download or read book Operational Plan written by Holly I. Dickson and published by . This book was released on 2020 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2020-2024, Chinook salmon (Oncorhynchus tshawytscha) will be enumerated at 2 Anchor River sites from mid-May through early August to monitor escapement for the drainage. The south fork site, located at approximately river kilometer (RKM) 4.0, will be monitored by an Adaptive Resolution Imaging Sonar (ARIS) during high flow periods, and a resistance board weir fitted with underwater video will be used thereafter. The north fork site, located at about RKM 5.3, will be monitored by a resistance board weir with underwater video from the beginning of the Chinook salmon run in early May. Motion-detection technology will be used at each weir to record fish passage 24 hours per day. Weekly beach seine surveys will be used to capture Chinook salmon for age-sex-length (ASL) samples downstream of the confluence of the south and north forks. Chinook salmon data will be used to update estimates of the spawner-recruit relationship and harvest rate, and to provide inseason run information to managers. Coho salmon and steelhead will also be monitored in the fall of each year using the resistance board weir and video system on each fork. Coho salmon age, sex, and length will be collected via beach seining. Coho salmon escapement and harvest rate will be estimated along with an index of steelhead abundance and catch rate.
