I am not a biologist by any means but feel like if you shut down the fishing on a lake for a while then opened it back up people would be catching more fish since the fish haven't seen any artificial baits in a while. I know they had a new lake here in tennessee that they opened this year after stocking it for a few years and heard it didn't matter what you fished with. It also would probably hurt the guides and stores around the lake that rely on fisherman. Doesn't seem this would be even an option to discuss
