... and not to mention the [non-tribal] netting that takes place in the saltwater along the migratory paths of steelhead and salmon from California up to Alaska and including BC and other Canadian-based sources.

The latest STS has an interesting artical on "selective" gillnetting and especially as it has impacted returns on the Columbia River system.

I believe that the "steelhead plan" intends to examine ALL sources of decline in the returns- including dams, commercial fishing, aquaculture, tribal fishery rites, etc. In addition, there is mention (perhaps also in the latest STS) that the senate issued mandate that the Snake River returns be re-examined and alternatives proposed. this would have to include the impact of the dams and irrigation practices on the east side of Washington State.
