Small Bait
The croaker's small mouth is suitable to thin, small, live bait. Croakers respond well to bait made up of small marine life, such as shrimp, and small fish, such as shiners. Croakers also respond to other generally used organic bait, such as worms. When combined with worms, smaller croakers will also respond more eagerly than usual to squid.
Large Bait
Larger marine life, such as squid, and cut bait are useful if made small enough for a croaker to eat. When cutting squid to size for a croaker, cut it lengthwise into thin strips; the piece of squid must be thin enough to fit into the croaker's mouth. Cut bait and squid are likely to attract larger croakers than it will small ones.
Rig
Croakers are adept at stealing the bait from the hook, so a two-hook rig makes it more likely that you will be able to keep the croaker on the line once he takes your bait. A rig that works well to catch croakers might have a top and bottom made of wire -- simpler is better -- and has two size No. 4 spanner hooks attached to it.
Hooks
Spinner hooks are preferable, because the hook acts to attract the croaker to the bait. Since croaker are a bay fish, and their native water is likely to be cloudy, the spinner's relative ability to catch the fish's eye is useful. A small hook -- of about size No. 4 -- is preferable because it will be small enough to hold the croaker's thin bait.
