I have a couple of questions that may have been answered elsewhere, but anyway, here goes: What is the top size for eating catfish? In other words, at what size should they be released? (We catch Channel, Flathead, and Blue Cats mainly where I fish). Are Bullhead catfish good to eat? I am pretty sure that's what we caught a few of earlier. They were good sized, like 3-4 pounds, but I wan't to make sure before I cook them up. Thanks in advance from a new guy and his fishing buddies (2 sons).
