The problem may be that you don't know how to cook drums. They lose their flavor quickly if they aren't filleted and put on ice promptly, but putting the live fish on ice is another way to preserve them until you get home. So stop with the clubbing--apart from prematurely killing the fish, it's not going to make for the ideal table presentation.
the red drum is often blackened in Cajun cuisine, and you can prepare the freshwater drum this way, too. It is a low oil fish, so you have to be careful not to dry them out when you cook them. Pan or deep frying them is recommended, as is smoking as long as you don't heat them for too long. Some people say they are as good, or better, than the walleye as an eating fish.
