Live bait. Spring time when they're wakin up, they'll eat FRESH cut bait. Big slabs of shad have worked for me. If i'm targeting them, I'll have one or two with that presentation out there. Big Shad, and Green Sunfish are my go-to's. Below that is kind of wash of whatever you catch in your net. Bluegills are good but don't live as long as the greenies for some reason. Flatheads just like them better. Idk why, I'm not a biologist. I've caught them on small buffalo and Drum also. I've heard that they really like Yellow Bass too. I wouldn't know personally because that's a no no. This is all river fishing. I don't really try to target them in lakes other than tossin a couple LB's out while catchin blues.
