Ive never heard of Superworms for catfish bait until last night while bank fishing on the Ohio river. There was an older gentleman fishing just down the bank from us and looked to be using nightcrawlers from the container he had beside his chair. As darkness approached he gathered up his gear and came over to ask if we wanted the rest of his bait. "Sure" I said "what do you got?" Well he smiled with a big grin and said "I got these Superworms here if you want them". So we gladley accepted and he hurried off and left. I decided what the heck, why not try one and here is what I have learned about Superworms: 1. In the first picture below, they are quite different looking from your ordinary earthworm. 2. They are very aggressive worms and can do some real physical damage when trying to put one on the hook. (2nd picture below). 3. They wont stay on the hook very long because they are strong enough to straighten out the hook or even break it to escape.(3rd Pic) 4. We actually got lucky enough to catch a catfish on one but as you can see the Superworm really wooped up on this catfish with some heavy blows to the head and body during the battle. The catfish later died from internal injuries that were caused by the punching and slugging from the Superworm.
