Crappie are popular freshwater fish that belong to the sunfish family, known scientifically as the genus Pomoxis. They are prized by anglers across North America. This guide details the common physical traits, general coloration, and specific markings that distinguish the two primary species, the Black Crappie and the White Crappie.
Shared Physical Traits
Crappie possess a distinctive body shape characteristic of the sunfish family. Their body is deep and noticeably flattened from side to side, giving them a thin, slab-sided profile. They generally range in size from 8 to 12 inches in length, though they can grow larger. Crappie have a relatively small, upturned mouth that extends to a point below the eye. A noticeable feature is the large size of their dorsal (top) and anal (bottom) fins, which are nearly identical in shape and positioned far back on the body.
Key Identification Features: Color and Markings
The general appearance of a crappie can vary significantly based on the water they inhabit. Crappie typically exhibit a base color that is silvery-white on the belly, transitioning to a light olive or green-gold on the back. Fish living in clear water often display darker, richer colors, while those from murky environments tend to be paler. The presence of dark spots or blotches across the body and fins is a primary identification feature. These markings are present in both species. The dark pigment frequently extends into the fins, creating visible rows of spots on the dorsal, caudal (tail), and anal fins.
Distinguishing Black and White Crappie
While the two species share a similar look, the most reliable method for telling them apart involves examining the spiny portion of the dorsal fin. Black Crappie consistently have seven or eight rigid spines in their dorsal fin. In contrast, the White Crappie will only possess five or six dorsal spines.
The second primary distinction is found in the pattern of their dark markings. Black Crappie feature irregular, scattered black speckles or blotches that cover the sides with no clear arrangement. White Crappie display their dark pigment in a pattern of five to ten distinct vertical bars running down their sides. This difference in marking pattern is often the easiest field identification feature when a spine count is not practical.
