Abstract
ABSTRACT We obtained age-and-growth data from 34 black crappie (Pomoxis nigromaculatus) samples from 25 water bodies and nine white crappie (P. annularis) samples from four water bodies in South Dakota from 1990 through 1993. Mean back-calculated length for black crappie was significantly different among water body type [i.e., small impoundments (< 40 ha), reservoirs (≥ 40 ha) and natural lakes] for all ages (P ≤ 0.01). Growth was slowest in small impoundments and fastest in natural lakes. Ultimate length (L.) was significantly correlated with mean back-calculated length at age (P ≤ 0.01). Mean length at time of capture varied monthly for white crappies. Age-2 white crappies completed 71% of their growth in length during July and August.
