As long as people are within their legal limits, they should never be hassled. After that it becomes simply a moral issue. Too many people have adopted the narrow view that the bass is a gamefish ONLY, and that C&R is the only acceptable practice. Fact is, to many people bass are (and always have been) table fare. Give the tourney biz its due, they have brought the benefits of selective harvest and C&R to the fore--and there's no doubt that they have had a positive impact on the fishery. But total C&R is an extreme view, and it is NOT what the law supports.
Yes, the guides depend upon this self-renewing resource for their living, and so it's to their advantage to TEACH, to lead by example and to enlighten through their experience. However, they have no right to say that a license holder fishing for bass with live bait and keeping a limit for the table is doing anything wrong.
Meanwhile, I happen to believe that if you're fishing a tourney and catch a fish of another species, it should NOT go in your livewell. But the law doesn't state that. Until it does, I have no business trying to force my views upon you.
