OK, I'm new to the keeping and cleaning catfish for a meal club and I had a miserable time trying to dispatch the catfish before I cleaned them. I used a metal bar like a tire iron and whacked the poor fish on the head about 10 times and it was still breathing and flopping around. Heck, I even felt sorry for the darn things. There has to be a quick, clean way of doing this but I don't know what it is. I used a hammer the second time and that was a little better but I don't know maybe I'm getting soft in my old age, it just seemed a little.... ahhh... rough? So, how do you kill your catfish before cleaning?
