Yep trim the fins on your live bait. Why? When a brim or crappie esp gets eaten/hit they expand the dorsal fin sticking the other fish in the mouth of couse that hurts and it also makes them harder to be swallowed. The ol Run & Drop which sucks, I trim ALL the fins to help prevent this. I also trim off the tail fin which slows the baitfish down making it easier to be caught and eaten. I am not sure but even makes them send out a distress sound/signal and attracting other fish to them? Now I do not claim to be Mr. Catfish however the people I have taken fishing with me and doing this from then on when they get on the boat look for the sissors as they have became belivers in this. Anyway try it and I think you will catch more fish.
