First off, let me say I've never kept a fish, because I don't know how to clean fish.
But just supposing I wanted to, if every Smokies fisherman wanted to keep a few fish to eat, would this affect the overall population of the fish in the park to any degree?
I heard one fellow say one time that there are a lot of predators for these fish that are a lot more of a threat than any fisherman - snakes, raccoons, river otter, king fisher, etc.
I also get the impression that the GSMNP has a pretty liberal policy of your being able to "keep" five fish per day because they are confident that the fisherman that can actually bring 5 to hand is going to be a rare bird.
Thoughts on this?
