I do them the same as I do shad. Stick them in the brain box with my bait knife so they quit flopping. Rake their scales off so they don’t foul the hook point. Cut them into chunks from the top down, generally about 1/2” cuts but I leave a good bit on behind the head to have for one big bait. I always cut the tail off and toss it too, maybe superstition or maybe real but I never fish tails, old guy told me they weren’t good bait and I just went with it.
