Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to conduct a full stock assessment of Chilkat River coho salmon Oncorhynchus kisutch. Coho salmon smolt were captured in the Chilkat River during spring 2009, marked with an adipose fin clip and a coded wire tag (CWT), and sampled for age, weight, and length. In 2010, adult coho salmon were sampled for CWTs in sport and commercial fishery harvests throughout Southeast Alaska and in the Chilkat River to estimate the marked fraction. In addition, the 2010 escapement to the Chilkat River was estimated by expanding peak survey counts.

Available in PDF, EPUB and Kindle. Book excerpt: An ongoing coded-wire tag project, used as part of a stock assessment program for Chilkat River Chinook salmon Oncorhynchus tshawytscha and coho salmon Oncorhynchus kisutch, will be conducted during fall 2019 and spring 2020 to provide estimates of smolt abundance and marine harvest for Chinook and coho salmon. This project uses modified Peterson 2-event mark-recapture methods to estimate smolt abundance, and port and creel sampling of coded-wire tags in mixed stock commercial and sport fisheries to estimate marine harvest for both species. Juvenile salmon will be measured for length and weight, marked with adipose fin clips, and tagged with coded wire tags in fall 2019 (juvenile Chinook salmon) and spring 2020 (Chinook and coho salmon smolt) as event 1 of the mark-recapture study. During event 2, adult Chinook salmon will be sampled for missing adipose fins, coded wire tags, age, sex, and length in Chilkat River fishwheels and drift gillnets, which are operated in the lower Chilkat River as part of a separate adult mark-recapture project. Adult Chinook salmon will be also sampled for missing adipose fins, coded wire tags, and age, sex, and length during Chilkat River drainage spawning grounds surveys to complete event 2 sampling. Coho salmon will also be sampled as adults during event 2 in the lower Chilkat River fishwheels. Age composition of Chinook salmon adults will be estimated by scale ageing techniques; age composition of coho salmon smolt and adults will also be estimated. The Alaska Department of Fish and Game uses these data to make local and regional management decisions. Chilkat Chinook salmon is a Pacific Salmon Commission exploitation rate and escapement indicator stock and has recently been added to the base model of abundance indicator stocks for the Chinook Technical Committee, which influences coastwide management
