Raeder RS, Rood V, Gavitt B. 1998. Abundance and Run Timing of Adult Salmon in Tanada Creek 1998 Report. Copper Center, AK
From June 2 to August 21, 1998, a portable rigid weir was operated on Tanada Creek, a third order perennial stream and a tributary to the Upper Copper River in southeast interior Alaska. This is the second consecutive year of weir operation at this site in a projected three year study. A total of 28,992 sockeye salmon (Oncorhynchus nerka) and 2 chinook salmon (O. tshawytscha) was counted. A total of 137 sockeye salmon was sampled for age, length and sex frequencies. Females comprised 49% of the sample. Average mid-eye to fork length for female sockeye salmon was 540 mm (N=67, SD=30)and 600 mm (N=70, SD=30) for males. Two age groups were present in the sample, with age 1.3 representing 98% of those sampled, and age 1.2 representing 2%.
