I am going to over simplify...so what's new? If I can use it, I'll kill it. I don't adhere to the "kill it for fertilizer" group, and I don't trust the percentages supplied by any group with interests in specific types of fish management. If it lives and spawns, and some of the eggs hatch, and some of the adults return, I have more fish to catch. The eggs that didn't hatch supplied nutrients, the fingerlings and smolts that got ate up by other fish/birds/seals supplied nutrients, the adults that didn't return either supplied nutrients or food for my competitors and companions.

I ask myself if the naturally spawing hatchery adult return numbers are so low, then how can they create any significant impact? If anyone anywhere can promise me that for every hatchery fish I bonk, I'll receive in the river one more adult wild steelhead, then I'll go for it. But you can't so I won't. Simple, see?
And by the way, if you bonk it, punch it, and toss it back....no sweat by me.
