Description and Size:

Pomoxis is Greek for "opercle sharp" and refers to the fact that the fish's gill covers have spines. The word annularis is Latin for "having rings" and refers to the dark bands (vertical bars) around the body. The white crappie is deep-bodied and silvery in color, ranging from silvery-white on the belly to a silvery-green or even dark green on the back. There are several vertical bars on the sides. The dorsal fin has a maximum of six spines. Males may develop dark coloration in the throat region during the spring spawning season.

Biology

Like other members of the sunfish family, white crappie are nest builders. They are similar to bluegills in that they tend to nest in relatively large "beds," and they have very high reproductive potential which often leads to overpopulation and stunting in small lakes and impoundments. White crappie nest in the spring, generally when water temperatures reach 65°F to 70°F. However, spawning activity has been observed at temperatures as low as 56°F. Fry hatch in three to five days, but remain attached to nest substrate by an adhesive substance from the egg for a few more days. Just before leaving the nest, fry free themselves by vigorous swimming actions. Once free, they begin feeding on microscopic animals. Although fry do not appear to school, fingerlings do. Schools with large numbers of individuals are often found in the middle of lakes. Typically, white crappie grow three to five inches in length the first year, and reach seven to eight inches during the second year. Maturity is usually reached in two to three years. Adults feed on small fish and insects.
