So are you saying that the only reason the wild populations are substantial is because the hatchery lacks the ability to capture the majority of the returning adults? And when you remove the hatchery, you potentialy remove a crutch for the wild runs because they are intermingled? Didn't they want to construct a tube so that anglers could toss in fish they would release (before cutbacks of course)?
I could see how that correlation would leave one to believe the hatcheries are good for the wild fish runs. Assuming the hatcheries clip all of their fish, I personaly fish the river and the majority of the kings I catch are wild.

And for the coho, the runs are still pretty fragile, so the lacking of hatchery coho fish will put pressure on the wild stocks from tribal harvest.

Did I work my way into your train of thought? If I didn't, I don't really care.
