For those looking for B&W answers regarding hatchery fish... it depends on your perspective. I think it's pretty easy.

If it's all about the well being of wild populations, then clearly less is best.

If it's all about harvest opportunity, then if a little is good, a lot must be better. If we're gonna have fish to harvest, hatchery fish are gonna be part of the game.

The tough part is striking a balance between those competing interests. So far the wild fish are losing.
