I am of the opinion that hatcheries are a necessary evil, but an evil just the same. And not all that necessary either.
Natural selection is just that - natural. Human induced selection however is not natural at all, eccentric to the cycles of nature fed with anti-biotics and chemically formulated pellets to raise fish 3x their natural counterparts with no sense of territorial bounds when pumped by the millions into river systems with snapping jaws eating alevin and fry of their brethren who are trying to exist naturally, ultimately resulting in artificial populations of drones who don't even have an urge to dig a redd.
Considering hatchery fish as equals to native fish is IMHO nothing more than delusional human rationalization for some financial, political or otherwise dishonorable agenda.
