Book excerpt: This report describes the results of the sockeye salmon Oncorhynchus nerka smolt monitoring project conducted by the Alaska Department of Fish and Game in the Chignik River system in 2021 and 2022. The research was designed to assess fish body condition and document relative abundance and outmigration timing in the Chignik River watershed. Sockeye salmon smolt were captured using a beach seine in Chignik Lagoon. In 2021, 1,348 ageable scale samples were collected. Of these, 974 (72.3%) were freshwater-age-1 and 370 (27.5%) were freshwater-age-2 smolt. In 2022, 1,378 ageable scale samples were collected. Of these, 752 (54.6%) were freshwater-age-1 and 377 (27.4%) were freshwater-age-2 smolt. Sockeye smolt were of above-average body condition in 2021 and 2022 when compared to historical data.

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 2020 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Chignik Management Area (Area L), the Chignik weir is the primary mode of enumeration for sockeye salmon Oncorhynchus nerka into the Chignik River. Annually, the Alaska Department of Fish and Game (ADF&G) samples salmon escapement at the Chignik weir for age, sex, and length (ASL) data. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of the sockeye salmon Oncorhynchus nerka smolt monitoring and enumeration project conducted by the Alaska Department of Fish and Game in the Chignik River system in 2016. The research was designed to estimate population size and age structure of outmigrating smolt, assess fish body condition, collect samples for future genetic stock identification analysis, and provide data for the Chignik River preseason adult sockeye salmon forecast. The abundance of sockeye salmon smolt was estimated using a rotary-screw trap array and mark-recapture techniques. In 2016, 3.5 million sockeye salmon smolt were estimated to have outmigrated from April 21 to June 11. Of these, approximately 10,600 (0.3%) were freshwater-age-0; 1.33 million (37.5%) were freshwater-age-1; 2.19 million (62.1%) were freshwater-age-2; and approximately 1,800 (

Download or read book Alaska Peninsula and Chignik Management Areas Sockeye Salmon Escapement Sampling Results 2018 written by Michelle L. Wattum and published by . This book was released on 2019 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of the 2018 Alaska Peninsula Management Area (Area M) and Chignik Management Area (CMA; Area L) salmon catch and escapement sampling programs. The purpose of this report is to serve as a compilation of data; interpretation and discussion of these data are limited. Sockeye salmon Oncorhynchus nerka escapements and smolt were sampled throughout these management areas. In Area M, the Alaska Department of Fish and Game (ADF&G) operated weirs at Bear River, Ilnik River, Nelson River, Orzinski Lake, and Sandy River; and in the CMA, ADF&G sampled sockeye salmon at the Chignik River weir. The projects estimated escapement and collected age, sex, and length data from adult salmon. Age, weight, and length data were collected from outmigrating sockeye salmon smolt from Bear and Orzinski rivers. The age structure of the late run of sockeye salmon to Bear River, the Nelson River sockeye salmon run, and Chignik early- and late-sockeye salmon runs were estimated from the available escapement and catch data associated with those systems and used for run reconstruction and brood table development.

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.
