The length-weight relationships for juveniles, form I, form II males, and females could be described as: WWT = 5 x 10(-3) TL3.09, WWT = 6 x 10(-3) TL3.61, WWT = 6 x 10(-9) TL3.26, and WWT = 6 x 10(-4) TL3.5, respectively. In all forms, growth was allometric (P < 0.05). The ANCOVA test indicated that slopes and intercepts of the length-weight regressions were significantly different between sex and sexual stages. The regressions for chelae length-width relationships for form I and form II males, and females were: ChW = -0.81 + 0.27CL, ChW = -0.33 + 0.25CL, and ChW = -0.82 + 0.32CL, respectively. Although the slope and intercepts of regressions for ChL and ChW were similar for those of form I and form II males, the slopes and intercepts of regressions of females were significantly different from form I and form II males. No statistical difference was observed in mean ChL between form II males and females (P > 0.05), but a significant difference was detected in mean ChL between form I and form II males (P < 0.05) and form I and females (P < 0.05). Form I males had longer ChL than form II males and females. The same trend was observed in mean ChW for form I and form II males, but a significant difference was detected between form II males and females (P < 0.05). In addition, results indicated that chelae lengths and widths increased allometrically with total length (TL) for both sex and sexual stages.eninfo:eu-repo/semantics/openAccessAstacus-Astacus LSexual DimorphismClarkii GirardPacifastacus-LeniusculusPopulation-DynamicsOrconectes-VirilisNoble CrayfishSizeDecapodaGrowthArticle23561662010.1111/j.1439-0426.2007.01015.x2-s2.0-34548577128Q3WOS:000249429700014Q3
