All I am saying is a river system with a hatchery that introduced eggs from another river (Skamania steelhead in the Cow) probably has no true "wild/Native" fish because of interbreeding with the hatchery fish.

My definition of a true wild fish, is a fish generated from the same gene pool as was in the river before the introduction of hatcheries.

True, rivers with hatcheries have natuarally spawning fish. But are they truely "wild"?

I don't think so. It is not the adipose that makes a fish wild. It is the gene pool that the fish came from.

Again, hatcheries make for some very fun and productive fishing. Lets build MORE.
