from an FWC officer. Was license checked while fishing and had a cooler with live largemouth that I was taking to the lake i live on. He asked to see them to make sure they were legal. I asked if what i was doing was ok? his reply was, as long as they are legal size and limit I can do whatever I want with them, law is possession.. Remember I'm talking about natives to your area. Yes, it would be illegal to release say a smallmouth bass or even a non-florida strain largemouth. also you can go on MYFWC.com to look at laws if you don't want to take my word for it. even done it with cichla while fishing in south florida(legal fish here). my sister in naples moved so we re- released the peacock bass back into the C4 canal where they were caught..
