Description: Juvenile coho salmon Oncorhynchus kisutch reared in hatcheries and released into several Northern Cook Inlet (NCI) freshwater systems in 1996 returned to Upper Cook Inlet (UCI) in 1997. Some fish in each release group were marked with an adipose finclip and a coded wire tag (CWT). Marked coho salmon were recovered in 1997 from selected UCI commercial fisheries and were used to estimate harvest of hatchery-produced coho salmon. In 1997 the UCI mixed-stock commercial fisheries harvested 152,836 coho salmon. The majority (89%) of coho salmon were harvested in the Central District drift gillnet fishery (79,094; 52%), the Northern District set gillnet fishery (37,369; 24%), and the Central District Upper Subdistrict (eastside) set gillnet fishery (19,668; 13%). Sample effort focused on coho salmon harvested in these three fisheries. NCI hatchery-stocked coho salmon contributed an estimated 9,534 (SE = 549) fish to the Central District driftnet fishery; 2,056 (SE = 232) fish to the Central District eastside setnet fishery; and 4,389 (SE = 138) fish to the Northern District setnet fishery. An escapement of 1,205 coho salmon into Ship Creek and 1,007 coho salmon into Campbell Creek exceeded the biological escapement goal of 200 coho salmon for each creek. Effort, harvest, and catch estimated from the Statewide Harvest Survey increased in 1997 relative to the 1988-1992 (prestocking) averages at Ship, Campbell, and Bird creeks, most likely due to the return of stocked coho salmon.
