For those that care about wild steelhead, the idea that hatchery-raised and wild steelhead don't mix has long been a matter of common sense. Wild steelhead are a marvel.

Those that do survive, and return to the rivers and streams where they were reared, pass on their uniquely adapted genetics to a new generation of wild steelhead.
