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 2005, marked with an adipose finclip and a coded wire tag (CWT), and sampled for age, weight, and length. In 2006, adult coho salmon were sampled for CWTs in recreational and commercial fisheries harvests throughout Southeast Alaska, and in the Chilkat River to determine the marked fraction. In addition, the escapement of adult coho salmon to the Chilkat River in 2006 was estimated by expanding peak survey counts.

Book Synopsis Deshka River Chinook and Coho Salmon Escapement Studies, 2005-2014 by : Daryl Lescanec

Available in PDF, EPUB and Kindle. Book excerpt: Chinook salmon (Oncorhynchus tshawytscha) and coho salmon (O. kisutch) annual escapements to the Deshka River were assessed from 2005 to 2014 to provide escapement counts and stock-specific biological information. Both Chinook and coho salmon were counted at a weir operated from approximately late May through mid-September each year, except for 2006 when coho salmon were counted through 16 August. The mean annual Chinook salmon weir count was 19,366 fish. Age composition for Chinook salmon averaged 30.8% age-1.2 fish, 50.4 % age-1.3 fish, and 16.7% age-1.4 fish. On average, females composed 48.3% of the runs. Chinook salmon run timing was consistent until 2013 and then quite variable in the last 2 years. On average, 50% (SE 8.1%) of the fish passed upstream of the weir by 20 June. Chinook salmon escapement goals were met for the years 2005-2007 and 2010-2014. The 2005-2014 mean annual coho salmon weir count was 18,684 fish. Above average coho salmon runs were observed in 2005 and 2006, whereas 2012 was the lowest count recorded since the weir was first operated in 1995. High water and a flood precluded complete coho salmon weir counts 2 of the 10 years. Coho salmon run timing was inconsistent (SD = 8 days at mean 50th percentile).
