Okay, now I will commit blasphemy! I think that salmon by some great design, are more adaptive than we know. Nature designed them to stray, to some extent, to replace fish that were eliminated by a catastrophic event. It seems to me, that by allowing large numbers of healthy returning hatchery fish, originally from the same basic stock, would bolster the number of spawners, which is what we need for recovery of "wild" stocks. Isn't that what one aspect of HSRG espoused?
