Summary

A total of 51,971 migrating adult chum salmon (Oncorhynchus keta) was enumerated at a weir on the Fishing Branch River from August 27 to October 17, 1995. The run was estimated to be 50.9% female (n = 51,971) and 0.6% age-31 70.6% age-4 sub(4), 27.7% age-51, and 1.2% age-61 (n=623). Fork length (mm) averaged 672 for males and 626 for females (n=795). A sample of post-spawn fish that drifted downstream onto the weir was 36.3% age-4 sub(), 57% age-5 sub(), 6.7% age-6 sub(1) (n=135), and 49% female (n=50). Estimated expenditure of milt/eggs averaged 86.5% for males (n=77, st. dev. = 40.5%) and 99.3% for females (n=73, st. dev.=37.2%). Seven chinook and 112 coho salmon were observed.
