Not really fair to call these guys by-catch, I absolutely love them. I'm in the process of moving right now. I live 300yds from the IRL, and I'm driving an hour to fish every day. If my snook & tarpon decide not to make an appearance, I'm have to find other ways to keep myself entertained. They seem to prefer crabs, though I've caught them on shrimp & glass minnow patterns, and 20-25lb flourocarbon is fine. Wire isn't necessary.
