| 摘 要： | 本文研究了东海银鲳个体生殖力的分布以及个体生殖力与各体征指标的关系。结果表明：银鲳的个体绝对生殖力ｒ、相对生殖力ｒ／Ｌ（绝对生殖力／体长）、ｒ／ｗ（绝对生殖力／体重）均服从正态分布。个体绝对生殖力ｒ和相对生殖力ｒ／Ｌ与各度量指标均为幂函数关系，与各称量指标则为线性相关，而个体相对生殖力ｒ／ｗ除了与性腺重、成熟系数相关外，与其它体征指标均不相关。本文还进一步给出了个体生殖力ｒ、ｒ／Ｌ、ｒ／ｗ均值的９５％置信区间及个体生殖力ｒ与各指标的多元回纳方程。

| Abstract: | Based on the specimens of silver pomfret collected from the East China Sea, the biometic data were obtained and the study of individual fecundity was studied.The results are summarized as follows:1.The individual obsolute fecundity r and felative recundity r/L,r/w(r=egg number,1 = body length,W=body weight)are all distributed norm-ally.That is The 95%precent confidence intervals on the means of r,r/l r/w are(80198.9
