The relationship between growth in white crappie, Pomoxis annularis Rafinesque, and climate, lake morphometry and population density was studied in 103 Texas reservoirs. Growth of age-0 through age-3 white crappie was significantly (P≤0.05) related to latitude, growing season and surface area. Growth of age-1 through age-5 white crappie also was related to annual precipitation. Multiple linear regression models with precipitation and mean catch per unit effort (CPUE) of white crappie as independent variables explained 14-22% of the variation in growth of age-0, -1 and -2 white crappie. By contrast, growth of age-3, -4 and -5 white crappie was unrelated to CPUE. Apparently, between age 2 and 3, the density of white crappie in Texas reservoirs falls below a density-dependent growth threshold beyond which growth is no longer related to density. This density-dependent threshold was most likely related to angler harvest of larger, older white crappie.
