re: Wanting to trade tuna for catfish

This. Anyone that says they can tell the difference between properly prepared fried catfish and fried bass is full of it. Maybe, just maybe a bigger catfish filet by texture.

But you take a 3 lb catfish and a 3 lb bass and fry both, its the same thing.

I honestly don't know why you'd trade catfish for tuna, that's like trading venison roast for a Prime filet. But whatever floats your boat.
