There are a lot of small, underslot black and red drum being caught right now. Very common after a hurricane.
They both have a slot limit that means it must be larger than X inches and smaller than Y inches to keep.
Red Drum 15-23" slot limit, 2 per person per day, 6 per boat.
Black Drum 14-27" slot limit, 5 per person per day.
Both are total length, measured with a pinched tail.
If you can't ID a fish, don't keep it. Some people have been taking pictures of fish on ice and asking what they are. Don't be like these people.
i got a few puppies and trout monday and threw all back but like you say i had people catching them and asking me what they were and i told them to release them but by then they most likley didnt survive.
