Shiners are well, shiners. That is the actual accepted common name, although there are a ton of diffenert species. Emerald shiners, golden shiners, spot tail shiners, etc. Most bait shops will also sell fathead minnows which are usually the cheapest bait fish they sell. Here in Kentucky we buy them by the pound for like $5. Any place where crappie fishing is big will have good prices on baitfish.
