White Crappie
All crappies have anal fins with 6 spines that are slightly longer than the dorsal fin (5-8 spines).  White crappies are silvery white, mottled with dark green with vertical bars on the sides.  Length up to 12.  Dorsal fin is also further back in white crappie than in black crappie (distance from eye to dorsal fin larger than length of the base of the dorsal fin; in black crappie, it is about the same distance).
