In the winter, crappie tend to move their schools to deeper water, and
they are just not as active. Being less active means they feed less,
but they do feed. Use small worms and crappie jigs, and be sure to fish
deep and move your bait slowly. These crappie will be lethargic, but
they can be caught particularly in deep cover and around deep
structure.
