What's wrong with catfish?
Maybe this will sway your opinion a bit.
Cut the head off, and remove what interior crap you can. Butter some tin foil, and place it in there. Season both sides with salt, pepper, white wine worchestire, lemon, cube of butter on top and a bit of granulated garlic.
Wrap up the tin foil, and place on the grill. Doesn't take long, peels right off the boe and is quite flavorful. I haven't done this is a while, so I may be missing an ingredient or two 🙂
