Artificials...
the small ones will bites your typical bass stuff like jerkbaits, crankbaits, small swimbaits on jigheads (kietechs).
The giant ones are usually taken on bigger 6 and 8 inch swimbaits and huge saltwater style jerkbaits usually in a gizzard shad or rainbow trout colors.
If you can net some gizzard shad and keep them alive, it's worth a try. And it's illegal to use trout as live bait ( I pretty sure that's correct, would have to double check the book)
