The answer is mass murder. Fish it HARD and pull them all that are under X number inches. I did 14" last year others do different sizes but the solution is the same. Eat them or cut them up and throw them back in. Bass will eat cut fish (especially if they are hungry) and they have no problem eating other bass. I catch as many LMB on cut bait as I do live bait and I way more than I do on lures. You can just throw them on the bank too if you don't want to mess with them.
