The 20 treaty Indian tribes in western Washington and the State of Washington are co-managers of salmon and steelhead resources. Co-management was established by U.S. v. Washington, the 1974 federal court ruling that upheld tribal treaty-reserved harvest rights.
Conservation is the goal of co-management. Harvest is focused on healthy stocks of hatchery and naturally spawning salmon and steelhead. The goal of harvest management is to conserve weak stocks while providing limited harvest opportunities that do not jeopardize recovery efforts. Unfortunately, wild salmon and many steelhead populations are in ongoing decline because their habitat has been damaged.
This is a high-level summary statistic characterizing the track record in achieving Endangered Species Act-related fishery objectives across particular stocks in a management unit from 2005-2016.
