中文摘要:报告了罗氏沼虾[Macrobrachiumrosenbergii(DeMan)]体长和体重的一些遗传参数:在体长为11.040±0.122(cm)、体重为42.258±1.740(g)时,雄体大于雌体。此时,体长与体重有显著的直线相关(r=0.912,P<0.01)。体重对体长的回归直线为W=13.056L—102.019,其中雌性为W=8.315L—55.311.雄性为W=16.17lL—134.406。罗氏沼虾体长的同类相关系数为0.0475,体重的同类相关系数为0.047716。
外文摘要:Some genetic parameters of M. rosenbergii are reported in this paper. the male M.rosebergii is larger than the female, when the body length is 11. 040±0. 122 (cm) and the weigth is 42. 258±1. 740(g). At this time, the linear relation between the body length and the weight is significant, (r=0. 912, p<0. 01). The linear regression equation of the weight (W) on the length (L) is W=13. 056L-102.019, in which the female is: W=8. 315L-55.311, and the male W=16. 171L-134. 406. The coefficient of correlation of the length for the same kind M. rosenbergii is 0. 0475, and that of the weight is 0. 047716.
