I found a very good article from 1991 debating the hatcheries vs wild fish. It's interesting to read 30 odd years later and think about the things they (the scientist) believed back then that came to fruition and the things that didn't.
UW experts debate what’s best for fish: wild runs or hatcheries

In the article, Donaldson indicates that to supply the number of fish that the world needs, (yes, it ain't all about us here in the northwest) hatcheries are it! There's no going backwards and it would be nice if certain individuals with dreams of rivers full of wild fish and a landscape covered with wild animals like deer, elk, moose, Wolves, Cougars, Black Bears, Grizzly Bears, Wolverines....etc. understood this. The idea that man can back up time without removing a large plethera of humans at the same time is absurd. Man is here, deal with it!
Instead of trying to figure out ways to move backwards, how about ya dreamers figure out how man is going to thrive through the next millennium.
