When the fish are active and feeding on bluegills, crappie, or shad, there are few things more effective than a swim jig. These jigs have a more cylindrical head shape, helping them navigate through grass or other forms of vertical cover. Swim jigs are normally paired with some kind of swimbait or plastic with a kicking action. This gives off the vibration that bass and other predatory fish can feel with their lateral lines. A simple cast and retrieve method is often best, as this allows the bait to swim with a very subtle action.
