Abstract
Populations of white crappie Pomoxis annularis were studied at four Missouri reservoirs to determine population characteristics and develop techniques to improve the quality of fishing. Trap-netting in October was used to sample white crappies in Stockton, Pomme de Terre, Lake of the Ozarks, and Wappapello reservoirs. At all four reservoirs, trap-net capture rates for year-classes that were age-2 or older were significantly correlated with estimated harvests the following year. Growth rates were consistently rated satisfactory; age-3 white crappies averaged 9 in or longer at all of the reservoirs except Wappapello, where they averaged 8.6 in. Trap-netting and creel surveys both indicated that the populations consisted mainly of young white crappies; few age-4 and older fish were captured in nets, and more than 90% of the harvest consisted of ages 1–3. Exploitation rates, determined from tag returns from white crappies tagged at Stockton and Pomme de Terre, were estimated to be about 60% for fish ...Keywords
