摘　　要：在长江口中华绒螯蟹亲蟹生殖洄游期间,通过研究中华绒螯蟹放流群体和自然群体繁殖力随壳宽的变化规律,比较放流群体和自然群体繁殖力的差异,从而评估人工增殖放流亲蟹的繁殖力。结果显示,随着壳宽的增大,中华绒螯蟹放流群体和自然群体的繁殖力都显著增加(P<0.05)。在相同壳宽范围内,放流群体和自然群体的繁殖力之间没有显著差异(P>0.05)。回归分析显示,放流群体繁殖力(F)与壳宽(CW)呈幂函数关系:F=3.979CW6.208(R2=0.822);自然群体F与CW呈幂函数关系:F=1.696CW6.636(R2=0.673)。协方差分析显示,放流群体与自然群体F与CW的两条曲线在显著性为0.05时拟合较好。研究结果表明,放流群体与自然群体的繁殖力与壳宽之间无显著性差异,推断放流亲蟹能够适应长江口天然水域环境,并与自然群体的繁殖力水平相当。During the reproductive migration of Chinese mitten crab in the Yangtze River estuary,the relationship between fecundity and carapace width of released and wild Chinese mitten crab populations was analyzed,and then the differences between the wild and released populations were compared.The results showed that,with the increase of carapace width(CW),the fecundity(F)of released and wild population crabs increased significantly(P<0.05).In the same range of carapace width,there was no significant differences of the fecundity between the wild and released populations(P>0.05).Regression analysis showed that the relationship between the F and CW of the released population belongs to exponential function,which is F=3.979CW6.208(R2=0.822).In addition,the relationship between F and CW of the wild population is F=1.696CW6.636(R2=0.673).Covariance analysis showed that the curves of the wild and released crab populations fit well in significant 0.05.It could be concluded that the fecundity of the wild and released populations was at the same level.There was no significant difference between the wild and released crab population on the relationship of F and CW.The released population could reproduce well in the natural water of the Yangtze River estuary.
