摘要

Length weight (body length; L-B versus wet weight; W-wT) and chelae length width (L-Ch versus W-Ch) relationships were determined for male and female crayfish (Procambarus clarkii) under culture conditions. The length weight relationships for males, females, and total individuals were described as W-WT = 0.014 x L-B(3.603), W-WT = 0.020 x L-B(3.350), and W-WT = 0.0 17 x L-B(3.467), respectively. This relationship was significantly different (p < 0.001) between males and females. Compared to females, males were heavier and their tail length was shorter (p < 0.001). No statistical difference was observed in mean L-Ch, cheliped length (L-Cp), and W-Ch between the right and left sides within a gender (p > 0.05), but significant differences were detected between males and females (p < 0.001). The regressions for L-Ch versus W-Ch for males and females were W-Ch = 3.083 x L-ch(0.847) and W-Ch = 0.284 x L-Ch(1.232) respectively. This regression differed significantly between males and females; males' chelae were wider than those of females (p < 0.00). L-Cp, L-Cp, and W-Ch were highly related to LB; males had longer L-Ch and L-Cp and wider W-Ch than females. Individuals without chelipeds were measured to determine the relationship between the length and body weight (W-BW). The L-B-L-BW relationships for males and females were described as W-BW = 0.074 x L-B(2.638) and W-BW = 0.033 x L-B(3.023) respectively. Females exhibited positive allometric growth (b > 3), and males showed negative allometric growth (b < 3). No statistical difference was observed in mean W-BW between males and females when LB was used as a covariate (p > 0.05).
