| Abstract: | Chinook salmon Oncorhynchus tshawytscha and coho salmon O. kisutch returns to Deep Creek were assessed with a weir to provide total escapement counts. From 15 June through 8 September 2000, 1,240 Chinook salmon and 3,425 coho salmon were counted and examined for adipose finclips. Total Chinook and coho salmon escapement was 1,103 and 3,424 fish, respectively. Coded wire tag information was recovered from 137 Chinook salmon with adipose finclips. No marked coho salmon stocked at Homer Spit were recovered from the 2000 return of coho salmon to Deep Creek weir. The contribution of hatchery-produced Ninilchik River Chinook salmon was 53 fish or 4.0% of the total Chinook salmon return. Females comprised 51% and males 49% of the Chinook salmon escapement. The age class composition of the Chinook escapement was dominated by age 1.3 (61%, SE = 5%), followed by age 1.2 (12%, SE = 4%) and age 1.4 (8%, SE = 4%). The coho salmon escapement consisted of 53% (SE = 3%) females and 47% (SE = 3%) males. The majority of coho in the escapement was age class 2.1 (79%, SE = 3%). |
