Based on monthly variation in the marginal index (MI) of the shell, it is assumed that rings are formed once a year during the period from July to August in this species. The relationship between shell length (SL; mm) and shell height (SH; mm) was expressed by the equation SH=0.8053SL-2.9636 (R 2 =0.94) and between SL and shell width (SW; mm) by the equation SW=0.5648SL-3.7105 (R 2 =0.90). The relationship between SL and total weight (TW; g) was expressed by the following equation: TW=0.00009SL 3.2141 (R 2 =0.96). von Bertalanffy s growth parameters were estimated using the regression wizard in the SigmaPlot computer program (Systat Software, Inc., v. 10.0). The maximum shell length (SL ) was 126.16 mm, growth rate was 0.2030/year, theoretical age at shell length 0 (t 0 ) was -0.52 years, and asymptotic total weight (TW ) was 509.17 g. Growth curves for SL and TW fitted to the von Bertalanffy s equation were expressed as follows: SL t = 126.16(1-e -0.2030(t+0.52) ), TW t =509.17(1-e -0.2030(t+0.52) ) 3.2141.
