Abstract:

The kuruma shrimp Marsupenaeus japonicus is widely distributed throughout the Indo-West Paci?c. Two morphologically similar varieties I and II were recognized along the coast of China. The growth characteristics were studied on the basis of the successive data of body length and body weight of Marsupenaeus japonicus cultured in indoor cultivation environment. The results showed that the relationships between body length and body weight can be described by the power functions as follows: VarietyⅠ(♀): W=0.013×L2.973, VarietyⅠ(♂): W=0.013×L2.960, VarietyⅡ(♀): W=0.009×L3.103, VarietyⅡ(♂): W=0.009×L3.120, where the value b in W=a×Lb was all close to 3, indicating an isometric growth. The von Bertallanffy equations were expressed as follows: VarietyⅠ(♀): Lt=15.932× [1-e-0.0067(t-26.5055)], Wt=48.798×[1-e-0.0067(t-26.5055)]2.973; VarietyⅠ(♂): Lt=13.642×[1-e-0.0091(t-35.0053)], Wt=30.437×[1-e-0.0091(t-35.0053)]2.969; VarietyⅡ(♀): Lt=13.865×[1-e-0.0077(t-22.8107)], Wt=31.449× [1-e-0.0077(t-22.8107)]3.103; VarietyⅡ(♂): Lt=12.094×[1-e-0.0102(t-32.6776)], Wt=21.470×[1-e-0.0102(t-32.6776)]3.120. Further analysis of their asymptotic values of body length, body weight and longevity showed that the female was higher than male and that VarietyⅠwas higher than VarietyⅡ.
