I agree with Greg, but I'll take it a step further by singling out one fin--

You MUST cut the caudal fin. I've had the same experience as Greg's clients in that I caught 2 bass with literally no dorsal fin or pelvic fins left, but I had not previously cut the caudal fin. If that bass still has an intact caudal fin, you can't be sure it will get eaten.

"Only after sorrow's hand has bowed your head will life become truly real to you; then you will acquire the noble spirituality which intensifies the reality of life. I go to an all-powerful God. Beyond that I have no knowledge--no fear--only faith."
