Fishmyster:
You make an interesting point - that repeated C&R has absolutely no impact on fish. Period. Ever.
As a pretty keen angler myself, and one who does at least his share of C&R I wish you were right. But unfortunately you're not. It's basic common sense. The more a fish is hooked, the greater its shance of a fatal encounter with a deep hook. I'm not raving eco freak or C&R apologist. I like to catch fish as much as the next guy and have no issue with C&R or retention, for that matter. The chances of a fish getting f#ed up by a hook increases directly with the number of times its caught. Its simple probability my friend. What you do does impact the stock, as does my fishing time. Thats what mortaility rates are all about. They may be low, but they're not zero.
What does make sense is your assertion that by repeatedly catching the same fish over and over again, that we achieve greater social and economic beneift from that fish. True enough, and excellent justification for continuing or increasing hatchery production in rivers that are conducive to the kind of pressure that jets create.
I have abolustely no issue with what you do, I just don't agree with the idea that its a good thing for every flow.
Tight lines...
Gooey out on this subject.
