The wife's family and my buddy always do several fish fries a year. We'll normally catch a bunch of bream, crappie and cats on Eufaula or cook up the ones my buddy and I catch on the St. Johns. We always make it kind of a big deal. I made an attempt to get involved in the cooking several years back and bought the tank, stand, huge metal cooking pot and basket at Lowe's. Found out after 3-4 fries that I'd much rather let them do the cooking while I stand there, drink beer and talk shit about who caught the biggest, smallest and how the sumbitch driving the boat kept putting me out in the deep water in the back of the boat while he eased up to the structure off the front. At least that's my excuse.
As far as salt water fish, I think mahi is my all around favorite. Always a solid, clean tasting fish. Snapper can be excellent but more often than not, it seems to have an overpowering "Fishy" taste. Used to think that was just because I would normally buy it and it was due to it being previously frozen, but I've had it be strong fresh off the boat. Scamp is another cut that I've never had a bad piece of meat.
