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.

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.

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.

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 excerpt: The Chilkat 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, (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.

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

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.

This book was released on 2020 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: This operational plan describes the procedures for the sockeye salmon Oncorhynchus nerka smolt sampling project conducted by the Alaska Department of Fish and Game (ADF&G) in the Chignik River system. The project goal is to evaluate and document size and abundance trends of sockeye salmon smolt in the Chignik River system to understand rearing capacity and habitat use. The research is designed to assess age structure, fish body condition, and provide additional context for the adult sockeye salmon forecast. Age structure of the population will be estimated from scales of sockeye salmon smolt collected using a beach seine. Juvenile salmon habitat use will be examined by beach seining in near-shore marine environment. Findings from this project are vital for understanding effects of the commercial fishery and environmental changes occurring in the Chignik River system on the sockeye salmon population.

This book was released on 2021 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game, Division of Commercial Fisheries, monitors annual escapements of salmon returning to the Situk River system near Yakutat, Alaska. A weir in the lower river provides the primary mode of enumeration for sockeye Oncorhynchus nerka and Chinook O. tshawytscha salmon escapements into the Situk River. Information provided by this project is used inseason to manage the Situk-Ahrnklin Inlet commercial set gillnet fishery and the inriver sport fisheries to ensure escapement goals are met and to maximize and sustain the harvest of salmon from the Situk River. A two-person crew will enumerate all species of salmon through the Situk River weir and sample adult sockeye and Chinook salmon for biological characteristics (age, sex, and length). This report provides operational guidelines for the Situk River adult salmon weir project, including salmon enumeration, sampling procedures, and weir protocols.

This book was released on 2021 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project is to provide biological data (age determination, length, and sex) from commercial salmon catch (harvest) and escapements to assist with the inseason and long-term management of salmon in the Kodiak Management Area (KMA). The Alaska Department of Fish and Game (ADF&G) Division of Commercial Fisheries annually samples sockeye salmon Oncorhynchus nerka escapements and catch in the KMA. Biological information such as age, sex, and length are collected from escapements in the Karluk, Ayakulik, Upper Station, Frazer, Afognak (Litnik), Saltery, and Pasagshak systems. In 1985, an expanded commercial salmon catch sampling operation was initiated in the KMA that, in combination with the escapement sampling, provides the foundation for preseason run forecasts, escapement goal evaluation, and assignment of the run to stock of origin (run reconstruction). Commercial sockeye salmon catch will be sampled for age from individual districts and sections throughout the KMA.

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 10 other drainages on the Kodiak road system (KRS) will also be indexed. 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 explore 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 7 KRS rivers without SEGs (Monashka, Pillar, Salonie, Felton, Roslyn, Sargent, and Russian). The Pasagshak River coho salmon escapement will also be estimated with a temporally stratified mark-recapture study.
