I do catch and realease on all Largemouth and Smallmouth Bass but other fish i tend to keep em and cook them so wats your favortie fish to eat mine is White Crappie.
I love walleye and pike. I also love perch although i only ever ice fish for them, i'm not sure about them by mid summer. smallies also taste great if caught from cooler water. Gotta love fresh salmon and all the trout's.As far as eating size goes i like to eat 'teenagers'. if you wanted to eat a human you'd choose a nice strong new muscle toned early 20 something, nice lean meat and not some saggy tough old granny, the same goes for fish. (weird analogy i know, but it works for me!)
I think crappie have kind of a generic taste. Often, When cooking them in the same batch as bluegills I can't tell a difference except for the thickness of the fillets.
