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.

Download or read book Operational Plan Situk River Salmon Enumeration and Sampling Procedures 2021 2022 written by Richard A. Hoffman (Biologist) and published by . 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.

Book excerpt: The Alaska Department of Fish and Game, Division of Commercial Fisheries, monitors annual escapements of salmon returning to the Nushagak River system near Dillingham, Alaska. Hydroacoustic techniques, dual frequency identification sonar (DIDSON), are used to develop escapement estimates of sockeye Oncorhynchus nerka, Chinook O. Tshawytscha, chum O. keta, coho O. kisutch, and pink O. gorbuscha salmon into the Nushagak River. Sonar passage estimates are used for inseason management of commercial fisheries in the Nushagak District. Estimates of species composition, age, sex, and length, are derived from samples obtained with drift gillnets. This report provides operational guidelines for the Nushagak River sonar project, estimation of salmon escapement, and sampling procedures, as well as general camp policies.
