I have cleaned and eaten quite a few catfish in the last 30 or so years and firmly beleive any fish over 1 lb is too big to eat. The bigger the fish is, the softer the texture of that fish is going to be. Also, cleaning the smaller fish is a lot easier than cleaning the bigger fish. You can hold them in your hand for the skinning process. Personally, I feel the need for selective harvest in catfish the same as we have for walleyes. I fish mainly in pool #14 and have observed first hand what commercial fishing and overharvest have done to this fishery. I do enjoy catching large catfish, but I also enjoy releasing them, to bend someone elses pole in the future. Just my .02.
