摘要

鱼类生殖力的研究，由于计数卵量方法上有了很大的改进，因而已逐渐成为鱼类生态和渔业资源研究上的一个常规观测项目。生殖力的变动，经常被用来作为判断补充与资源状况的指标之一。我国从50年代初就开展了这方面的研究。例如，在我国烟台外海鲐鱼资源的研究中曾指出，1954-1957年间，随着鲐鱼资源的逐年下降，生殖力不仅表现出明显的提高现象，而且与鲐鱼的生长有关。本文是从所积累的大黄鱼Pseudosciaena crocea (Richardson)生殖力研究资料中，选择1959年5-6月间，同期分别在两个不同产卵场上所收集的资料，对其个体生殖力和种群生殖力的差值进行比较分析的结果。说明生活于不同水域中的种内不同种群，其生殖力调节方式也是不同的。这两个种群分属于两个地理种群，浙江近海岱衢洋春季生殖种群属于大黄鱼分布区北部的岱衢族；福建近海官井洋春季生殖种群属于大黄鱼分布区中部的闽-粤东族。此外，文中还以这两个种群为例，对表示种群生殖力的某几个方法作了比较分析。

Abstract

This paper is the third of a series of studies on the intra-specific variation of fecundity of the Large Yellow Croaker. It presents the results of a comparison of the fecundities of two different spring spawning populations (the Taichu Yang and Kuanching Yang spring spawning populations, belonging to the Tai-chu race and Min Uehtung race, respectively). The samples consisting of 304 and 173 specimens, respectively of the above two populations were collected in 1959 during the period from May-June in their respective spawning grounds. Therefore, a11 the data are fully comparable.
