Couple things I have seen with the Tribes, and lots of folks here, is that a fish is a fish is a fish. The ecosystem knows differently, but it doesn't vote. If you look north of the border you will see some FN's saying that steelhead conservation needs should not constrain their salmon fisheries and it appears DFO rather agrees.

I support a triaged approach where watersheds reasonably intact are kept that way and managed for ecological levels of wild fish. Other (compromised) watersheds, like the Columbia, are managed with "replacement" fish.

The big "but" in my idea is that fisheries are still terminal as the wild fish have shown they can't absorb marine mixed stock fisheries.
