Identification Tips

1. 1

   Dorsal Fin Spines

   Count the spines in the dorsal fin. Black Crappie typically have 7 or 8 dorsal spines (rarely 6 or 9). This is the most reliable way to distinguish them from White Crappie, which have 5 or 6 dorsal spines.

2. 2

   Coloration and Pattern

   Observe the body pattern. Black Crappie have irregular, scattered black spots and blotches over their entire body, giving a 'speckled' appearance. White Crappie tend to have more organized, vertical bars.

3. 3

   Body Depth

   Black Crappie generally have a deeper, more compressed body compared to the slightly more elongated White Crappie.
