Without watching you handle a fish it is hard to say. But I would suggest you settle down, maybe you are just a bit over excited when catching? A lighter touch, and watch how you are grabbing the fish along with the wet towel and filet glove, mentioned above, should help.
I usually don't have a problem until winter Togging. Those crabs sure can get you. When I do come home with cuts I usually rinse my hands in Regular Listerine, it is actually an antiseptic so it helps keep the cuts clean.
