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.

The biological information collected from salmon escapements provide the foundation for preseason run forecasts, escapement goal evaluation, and run reconstruction. Every week throughout the season, 240 sockeye salmon are sampled. Sockeye salmon scales are collected using established protocols common to the Westward Region.

Download or read book Kodiak Management Area Harvest Strategy for the 2022 Commercial Salmon Fishery written by James Vincent Jackson and published by . This book was released on 2022 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game (ADF&G) will manage the commercial salmon fisheries in the Kodiak Management Area (KMA) to promote maximum sustained yield for future KMA salmon returns by achieving salmon escapement goals and providing opportunity to harvest salmon in excess of those goals. ADF&G will attempt to provide for orderly fisheries while maximizing harvest opportunities on the highest quality salmon. ADF&G will adhere to the biological and allocative requirements of the management plans adopted by the Alaska Board of Fisheries for the KMA. Management of the fisheries follows a general chronology based on the run timing of 4 commercially targeted salmon species: sockeye Oncorhynchus nerka, coho O. kisutch, pink O. gorbuscha, and chum salmon O. keta. The 2022 preseason forecasts project a harvest of approximately 3,254,800 sockeye, 453,300 coho, 19,437,600 pink, and 751,300 chum salmon. Additionally, about 7,150 Chinook salmon O. tshawytscha could be harvested incidentally in fisheries targeting other salmon species. All fishing periods are established by emergency order. The initial sockeye salmon commercial test fishing period for the west side of Kodiak Island is tentatively scheduled for June 9 but may occur as early as June 1. A June 9 fishery opening is also planned for the Duck Bay, Izhut Bay, Inner Kitoi Bay, Outer Kitoi Bay sections, and the Foul Bay and Waterfall Bay Special Harvest areas. The initial commercial test fishing period in the Alitak District will be determined based on inseason indicators of run strength. On July 6, the initial weekly fishing period targeting pink salmon will be 81 hours in length for Kodiak Archipelago sections, and the Mainland District fishing periods will be 57 hours in length.

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.

This book was released on 2020 with total page 116 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, follow appropriate principles and criteria in the Policy for the Management of Sustainable Salmon Fisheries, and achieve spawning escapement goals. 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. 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. 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.

Download or read book Lower Cook Inlet Aerial and Ground Survey Salmon Escapement Monitoring Operational Plan 2022 2024 written by Edward O. Otis and published by . This book was released on 2022 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: To facilitate informed inseason management of commercial fisheries targeting Pacific salmon Oncorhynchus spp., the Alaska Department of Fish and Game (ADF&G) uses aerial and ground survey methods to monitor escapement on select index streams in Lower Cook Inlet (LCI). Surveyors make periodic counts of sockeye O. nerka, chum O. keta, and pink O. gorbuscha salmon throughout the duration of their respective runs. Fishery managers use these data daily to manipulate time and area fishery openings/closures in an effort to assure that the final escapement level for monitored stocks falls within their individual escapement goal ranges. At the end of the season, periodic aerial and ground survey counts are used to calculate a final escapement index for each stream based on the area-under-the-curve method (pink and chum salmon) or the peak survey count (sockeye salmon). This report provides operational guidelines for aerial and ground survey-based monitoring of salmon escapements in LCI.

Results will be used by Alaska Department of Fish and Game (ADF&G) and Alaska Energy Authority (AEA) staff to evaluate the extent to which salmon access and use Red Lake. This project is 1 component of the AEA’s preliminary assessment of fishery resources in the Martin River drainage, which is under consideration for future hydroelectric power development. This plan documents procedures developed for estimating salmon escapement using unmanned, or autonomous video counting towers (AVCT) that employ above-stream remote video cameras and digital time-lapse recording equipment (Otis and Dickson 2002, Otis 2020). Hard drives will be retrieved monthly, and video reviewed to enumerate daily escapement for all species identified passing the video site.

Download or read book Kodiak Island Limnology Laboratory Analysis Operational Plan 2020 2022 written by Heather Finkle and published by . This book was released on 2020 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lake Assessment Project for Kodiak and Afognak islands was started in the mid-1980s as part of a comprehensive plan to assess the region’s sockeye salmon Oncorhynchus nerka production potential. As part of the Kodiak Regional Comprehensive Salmon Plan, limnological and fishery investigations were conducted simultaneously to determine the appropriate enhancement or rehabilitation strategies for depressed sockeye salmon stocks and the stocking potential of barriered lakes without anadromous fish. The Alaska Department of Fish and Game Near Island Laboratory (NIL) was established in 2000 and has collected, processed, and analyzed limnological samples to meet these goals. In 2013, NIL was renamed the Kodiak Island Laboratory (KIL) and became Kodiak Island Limnology Laboratory (KILL) in 2017. This operational plan outlines the procedures used to process limnological samples for components of nitrogen and phosphorous, silica, photosynthetic pigments, and zooplankton population characteristics. This operational plan is formatted for functional use as a laboratory manual.

This book was released on 2020 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this document is to provide commercial salmon fishermen and buyers with information and guidelines used by the Alaska Department of Fish and Game (ADF&G) to manage the commercial salmon fisheries of the North Alaska Peninsula during 2020. The 2020 projected North Alaska Peninsula salmon harvest is 2,667,800 fish: 2,800 Chinook salmon Oncorhynchus tshawytscha, 2,400,000 sockeye salmon O. nerka, 65,000 coho salmon O. kisutch, 50,000 pink salmon O. gorbuscha, and 150,000 chum salmon O. keta. The bulk of the salmon harvest is projected to occur in the Northern District between the Nelson Lagoon and Outer Port Heiden sections. The predominant gear types used in the North Alaska Peninsula are drift and set gillnets, though purse seine is a legal gear type in some areas. In 2020, salmon enumeration weirs on the Nelson, Bear, Sandy, and Ilnik rivers will be used to facilitate inseason escapement assessment and management.

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 book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Alaska Peninsula Management Area (Area M), weirs are a primary mode of enumeration for sockeye salmon Oncorhynchus nerka escapements into some area streams. Annually, the Alaska Department of Fish and Game (ADF&G) samples adult sockeye salmon escapements at the Nelson, Bear, Sandy, Ilnik, and Orzinski rivers, and McLees Lake for age, sex, and length (ASL) data. Out-migrating juvenile sockeye salmon (smolt) are also sampled for age, weight, and length (AWL) at Nelson, Bear, and Orzinski river weirs. The biological information collected from salmon escapements provide the foundation for preseason run forecasts, escapement goal evaluation, and accurate assignment of the run to stock-of-origin (run reconstruction) to some Alaska Peninsula systems. The use of this data assists with long-term management of sockeye salmon stocks while daily monitoring of the sockeye salmon escapements helps ensure that escapement goals are met. Operation guidelines for the six Area M ADF&G weir camps are presented, including weir installation instructions, salmon enumeration and sampling procedures, and general camp policies.
