I caught my PB on shrimp, a 39 pounder. I have caught several over 30 with shrimp as well. I usually target smaller cats to eat, 8-12 lbs are perfect for filleting. I buy the 60-70 count size in the seafood dept at Wally World. Best deal that I have found. Sometimes I peel them and sometimes I don't. Seems like if I peel them I get more bites. That could just be my imagination, as I have a vivid one. emoUpsmile
I read in a mag one time that mussels are bluecats favoite food and that is why I started using shrimp for bait. But I usually carry an assortment of baits when I go fishing for them. Cut bait is hard to beat in the summer time. Rsimms swears by chicken breasts, but I think that the reason for that it is easiest for him to acquire. (He has stock in Bi-Lo's.) emoPoke emoBigsmile Bait up 3 or 4 rods with different baits and let the catfish tell you what they prefer on that particular day. Skipjacks are probably the best overall bait that you could use.
I had rather be Crappie fishing though. emoBigsmile emoGeezer
