Book Description
Results of a study of the biological escapement goal for Chinook salmon, Oncorhynchus tshawytscha, from the Taku River. This study was investigated with information from a stock assessment program (1973-2007), catch sampling programs of the Canadian inriver gillnet fishery, the U.S. commercial gillnet fishery in Taku Inlet, the troll fishery in Southeast Alaska, and the U.S. recreational fishery near Juneau.

Book Description
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.
