Te presence of the hatchery fish directly led to the demise of the wilds. The first, and probably most damaging and most difficult to repair, is the excessive harvest of wild fish when they returned with the more abundant hatchery fish.

Steelhead returned over a long period and spawned over a long period because that is what worked for the run. The long return time, extended spawning, repeat spawners were all required for long-term sustainability.

We have "saved" a fraction of what is needed; the later returning fish.

Then, especially after decades of inbreeding, that hatchery fish introduced maladapted genes so that simply spawning with a wild fish killed off its production.

I believe that we can one or the other in a watershed but not both.
