Up to the north eastin AL on lake guntersville I just use scraps from whatever I hunted the year before. Deer, squirrel, rabbit dove, quail, it really doesn't matter. I put them in little sandwich bags and freeze them. If it's still frozen when I get to the water, I just throw the bag in the livewell when I get in the water and it's thawed by the time I get to where I'm going. If it's tough like a heart, meat trimmings or gizzard then nothing special is needed. A liver or a lung gets panty hose wrapped around it.
Salt pork works pretty good on trotlines. I hate the stuff but always end up with some every year for some reason. Just little 1/2" cubes does the trick. I've had them on bare hooks on a trotline when I baited every other hook with country ham. Out of date bologna works just as good if you salt it heavy. In early spring when everything is on bed I like onions. There is plenty of fish and eggs for them to eat so they don't want meat. Their meat will taste like onion though. You just have to make some hushpuppies with onions in them so you won't taste it in the fish.
