This book was released on 2022 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: A creel survey will be conducted to estimate sport angler effort, catch, and harvest of large (≥75 cm mid eye to tail fork length) early- and late-run Chinook salmon in the lower Kenai River between the Warren Ames Bridge (river mile [RM] 5.1) and Slikok Creek sanctuary area (RM 18.6). Creel survey estimates will be geographically stratified in relation to the RM 13.7 Kenai River Chinook salmon sonar to provide angler effort, catch, and harvest of large Chinook salmon. A standardized inriver netting project will be conducted in the Kenai River at RM 8.6 to index abundance and estimate the age, sex, and length (ASL) composition of large early- and late-run Chinook salmon. Inseason estimates of Chinook salmon catch and harvest, used in conjunction with sonar passage estimates, inseason catch rates, and the length of returning Chinook salmon from the inriver netting study are used by fisheries managers for inseason management decisions to achieve escapement goals. This plan covers the creel survey and inriver netting studies for the 2021–2023 seasons.

Available in PDF, EPUB and Kindle. Book excerpt: This plan describes the coded-wire tagging of juvenile Chinook salmon Oncorhynchus tshawytscha on the Unuk River for the 2019 and 2020 brood years, which covers the coded-wire tagging of parr in fall of 2020 and 2021 and smolt in spring of 2021 and 2022, and sampling returning adults for age, sex, length, and coded-wire tags in escapement from the 2022 through 2027 return years. This study provides estimates of smolt and parr abundance, overwinter (freshwater) survival, mean lengths of juveniles, and harvest information of Chinook salmon originating from the Unuk River in Southeast Alaska. A separate project will be conducted on the Unuk River that employs aerial and foot survey peak counts to estimate large (≥660 mm mid eye to fork of tail length) adult Chinook salmon returning to the river in 2020 and 2021. The primary goals of this and the companion study are to estimate inriver run size, total run size, marine harvest-exploitation rate and harvest distribution, smolt and parr abundance, marine survival (smolt to adult) and overwinter survival (parr to smolt). The Alaska Department of Fish and Game uses this information to make local and regional management decisions, and the Pacific Salmon Commission uses the data for coastwide management and stock assessment through the Chinook Technical Committee.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chinook salmon Oncorhynchus tshawytscha smolt abundance and adult escapement will be estimated for the Taku stock of Chinook salmon originating from the Canadian portions of the Taku River drainage above the U.S./Canada border. This large glacial river flows into Taku Inlet about 30 km northeast of Juneau, Alaska. A modified Petersen estimator will be used to estimate smolt abundance for the 2017-2019 brood years, which represent smolt leaving the system during 2019-2021. Chinook salmon smolt will be captured April through June, systematically sampled to estimate mean length and weight and all healthy fish will be implanted with a coded wire tag and marked with an adipose fin clip. Escapement of large (≥660 mm; mid eye to fork of tail) and medium (401–659 mm; similarly, mid eye to fork of tail) Taku River adult Chinook salmon will be estimated using mark-recapture methodology in 2019-2021. Adult Chinook salmon will be captured and marked near Canyon Island in the lower Taku River using fish wheels and drift gillnets from late April through early August. Each fish will be tagged with uniquely numbered, solid-core spaghetti tags, and two secondary marks. In addition, fish will be sampled for use in age, sex, and length composition estimates of the spawning escapement.

Download or read book Operational Plan Deshka River Salmon Weir 2021 2025 written by Daryl Lescanec and published by . This book was released on 2022 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Deshka River is the largest producer and has the largest sport fishery of Chinook salmon in the North Cook Inlet Management Area. The Deshka River weir has operated seasonally since 1995. A floating, resistance-board-weir is used at river mile (RM) 7 to enumerate Chinook and coho salmon and to collect age, sex, and length data from these species. The Deshka River sustainable escapement goal (SEG) range is currently 9,000–18,000 fish for Chinook salmon and 10,200–24,100 fish for coho salmon. Data collected at this weir are used to manage sport and commercial fisheries inseason and to develop and evaluate escapement goals. This project is also used as a platform to collect harvest data upstream of RM 7, passage data of other fish species, environmental data, and it provides recapture data for the greater Susitna River drainage Chinook salmon mark–recapture project.

Download or read book Operational Plan Chilkat River Chinook Salmon Escapement Studies in 2021 written by Brian W. Elliott and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chilkat River large (age-1.3 and older) Chinook salmon Oncorhynchus tshawytscha inriver abundance and age and sex composition will be estimated using a 2-event mark-recapture experiment in 2019. Event 1 capture and marking will be conducted in the lower Chilkat River, and event 2 recapture will be conducted in principal spawning areas within the Chilkat River drainage. Data produced from this project will include spawning abundance of large Chinook salmon, age and sex compositions of the run, and when possible, age-1.2 abundance and length composition in the Chilkat River drainage. Chilkat River Chinook salmon are an exploitation rate and escapement indicator stock for the Pacific Salmon Commission Chinook Technical Committee, and it has been proposed that this stock be included in the coastwide Chinook salmon model used by the Pacific Salmon Commission to monitor coastwide abundance. Mark-recapture experiments have been conducted in the Chilkat River drainage since 1991; escapement estimates for 1991-2018 have an average coefficient of variation of 14%, which contributes toward precise stock assessment production estimates for the Chilkat River Chinook salmon stock. As part of the ongoing Chilkat River Chinook salmon coded wire tag studies, all Chinook salmon encountered in the mark-recapture experiment will be examined for adipose fin clips and the presence of a coded wire tag, which can be used for estimating juvenile production and marine harvest. Data collected from this project will be used to create full production estimates for the Chilkat stock.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goals of this study are to estimate the number of Chinook salmon Oncorhynchus tshawytscha smolt leaving the Stikine River and the length and weight of these Chinook salmon smolt yearly from 2019-2021. In addition, the harvest and marine survival of adult Chinook salmon returning to the Stikine River in the corresponding 2017-2019 brood years will be estimated, as well as length and weight of coho salmon smolt yearly from 2019-2021. A modified Petersen 2-event mark-recapture project will be used to estimate smolt abundance, and a coded wire tag project in conjunction with harvest sampling programs will be used to estimate harvest. Chinook smolt will be marked with adipose fin clips and coded wire tags each spring. Marked fish will be recaptured through creel, port, and escapement sampling programs. The Alaska Department of Fish and Game and Fisheries and Oceans Canada use these data, along with adult escapement information, to make terminal and regional management decisions, and the Pacific Salmon Commission uses the data for coastwide management and stock assessment through the Transboundary and Chinook Technical Committees.

Download or read book Operational Plan Susitna River Chinook Salmon Inriver Abundance 2021 written by Johnathon K. Campbell and published by . This book was released on 2022 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study is to estimate the abundance of Chinook salmon at river mile (RM) 34 of the mainstem Susitna River and spawning distribution among 5 management areas in 2021. A 2-event, mark-recapture experiment in combination with radiotelemetry will be used. Fish wheels and gillnets will be operated at river mile (RM) 34 to capture Chinook salmon for marking with passive integrated transponder (PIT) and radiotelemetry tags. Recapture event sampling will occur at the Deshka River weir at RM 7 where a PIT detection array will be used. Eight radiotracking stations will be strategically placed throughout the drainage to determine when radiotagged fish move in and out of the 5 management zones, allowing a determination of spawning distribution. A concurrent genetics mark-recapture study will be performed using genetics samples taken from a systematic sample of all PIT-tagged fish. The applied radio tags will also be used to estimate handling effects. In the event of a sport fishery, the proportions of non-Deshka River Chinook salmon in the sport harvest taken in 2 sections of the Deshka River will also be estimated through sampling of axillary processes from harvested fish and genetic stock identification.
