I know a lot of people do it and a lot don't.I like fish and keep what I want too eat. About 20 years ago while working at a dealership in Bartow FL, a professional fisherman stopped by to have some work done on his trailer.I want mention any names, but he was on his way too some local pits(lakes) too shoot a fishing show.He came back by a week later, there were about 10 bass boats that were fishing with him and they gave everybody at the dealership all the bass they wanted, If I rememder right I think he said they had 100 + bass.Funny they show catch and release on the film you watch but you don't see all the other boats with them stuffing thier livewells full.
