Book Description
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).

Languages : en
Pages : 41
Book Description
Chinook salmon (Oncorhynchus tshawytscha) and coho salmon (O. kisutch) annual escapements to the Little Susitna River were assessed from 2012 to 2016 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. Not all counts were complete for each run. Complete weir counts for Chinook salmon from 2014 through 2016 ranged between 3,135 and 5,026 fish. For 2013-2016, age composition for Chinook salmon averaged 38.1% age-1.2 fish, 37.1% age-1.3 fish, and 13.6% age-1.4 fish. On average, females composed 35.5% of the runs. The midpoint of the Chinook salmon runs with complete counts varied between years from 11 to 23 June. Chinook salmon escapement goals were met for the years 2013-2016. The 2012, 2014, and 2016 mean annual coho salmon weir count was 13,680 fish. An above-average coho salmon run was observed in 2014, 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 5 years. The midpoint of the coho salmon runs varied between years with complete counts from 10 to 21 August.
