Catfish Bait?

[Smalls]

Fellas, I need a little advice here. I just started trying to run jug lines and trotlines on some of the bayous around here. Today was only the second time I've ever put out jugs. I baited them with chicken livers, but didn't catch anything. I don't think it was so much the type of bait, but the bait falling off the hook.

Any advice on how to keep it on, and what other kind of baits have y'all used to catch cats? I've always heard chicken liver was good, but ive heard it doesn't work as well for catching flatheads.
