Same genus/different species
White crappie are Pomoxis annularis.
Black crappie are Pomoxis negromaculatus.
We catch mostly whites and the color and shape vary widely. During the spring pre-spawn and spawn, the males are highly colored and almost look like blacks. Stunted fish have more defined shoulder humps, but the smaller fish - say those under 8" that we catch - are usually more elongated than larger fish since it seems that the "dish face" develops with age. Color has ranged between defined stripes to almost golden-white with very faint stripes. - Roberta
