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.
