Well, red drum their close relative were almost fished out they taste so darn good. It wasn't until extremely strict fishing regulations did they start coming back. I wonder if they just got a bad reputation and it has unfairly stuck? If you gave someone freshwater drum and told them it was something else, they may be more open to eating it? I caught fish in the 12"-15" range and they seemed like they would produce a decent fillet had I kept them... Not really sure I would want to eat a bottom fish out of the Mississippi to eat though. Maybe it isn't as badly polluted with contaminants as I think it is?
