Freshwater Fish Identification
White Crappie
Pomoxis annularis
Other names: White perch, sac-a-lait Status: Texas game fish
Description
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.
Angling Importance
Taken together, "crappie" (white and black combined) is the most popular
panfish in Texas. The crappie group is the third most preferred group overall,
ranking behind only "bass" and "catfish." Crappie are sought after by both bank
and boat anglers. Typically, minnows are the preferred bait, often producing
monumental results when an aggregation is located, usually around submerged
trees, boat docks, or other submerged structures. White crappie in excess of 4.5
pounds have been landed in Texas waters.
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.
Distribution
The native range of white crappie included the area west of the Appalachian
Mountains north to southern Ontario and south to the Gulf of Mexico. The range
extended west to Minnesota and South Dakota in the north, and to northeastern
Mexico in the south. Today the range extends east to the Atlantic coast, and
west to include California and portions of Nevada, Arizona, New Mexico, Montana,
Colorado, Utah, and North Dakota. White crappie are native to the eastern
two-thirds of Texas, but the species can now be found statewide except for the
upper portions of the Rio Grande and Pecos drainages.
