I seriously doubt that the tribes will fully embrace a wild steelhead recovery program. As is seen in GH with Chinook the tribal view is a fish is a fish is a fish. Attitude has been expressed elsewhere.

Even if they did not sell fish their worldview is that fish are there as a food source. Not a plaything. Unless and until that worldview changes steelhead don't have a chance. And I suspect, as development advances the tribes will push for more hatcheries as their measure of success is dead fish in the boat.
