We examined the contribution of natural coho salmon to the total coho salmon harvest in the Squaxin Island Tribes commercial coho salmon fishery during the 1999 and 2000 commercial fisheries, and the contribution of hatchery strays to coho salmon escapement in local streams. Commercial harvest during the two years was extremely variable. The 1999 harvest (5,282) was the lowest on record, while the 2000 harvest (77,847) was within the range observed during the past decade. Natural coho salmon contributed 5 percent or less of the total harvest during both years. This resulted in estimates of 131 and 3,808 natural coho salmon being intercepted in the 1999 and 2000 commercial coho salmon fisheries, respectively. Although these are relatively small numbers, they represented between 16 and 129 percent of the total escapement of coho salmon (both natural and hatchery) to local streams.
