Thanks Jeff,

This is what I was looking for. I've heard some stories, but hadn't seen the
studies yet. It looks like hatcheries can't do it "right", so we should just
get rid of them except maybe to attempt to re-introduce a run where the natives
are extinct.

Maybe there's a better way to do that too. I remember that when Mt. St.
Hellens erupted in 1980 there was an extreme gloom and doom attitude from the
fisheries department that turned out to be almost 100% wrong. The fish stayed
away for a year, and then started filling tight back in. The ones that stayed
away spawned elsewhere. I supposer the "right" way to re-introduce a run in an
extinct river is to leave the river alone and see who shows up.

Thanks again,

Chas
