【摘要】 研究结果显示:东海半滑舌鳎的个体绝对生殖力r波动于15．784×104-130．864× 104eggs之间,个体相对生殖力r／L波动于401-1899eggs／mm,个体相对生殖力r/W波动于 341-757eggs／g之间;个体生殖力与一些长度指标(体长、体厚、体高)呈幂函数关系,与体重呈线性关系;雌性半滑舌鳎的首次性成熟年龄为3龄,各年龄间个体绝对生殖力(r)和个体相对生殖力(r／L)差异显著,而个体相对生殖力(r／W)差异不显著;半滑舌鳎的体型雌雄间有显著差异,雄性比雌性细长、侧扁。更多还原

【Abstract】 The paper shows that absolute individual reproduction ability of C.semilaevis is between 15. 784×104- 130. 86×104eggs,and relative individual reproduction ability(r/L)is between 401 - 1899eggs/mm, and relative individual reproduction ability(r/W)is between 341 -757eggs/g.Individual reproduction ability is related with some length index (body length, body thickness and body breadth)in power function, and with the weight linearly.The difference between male and female C. semilaevis bodily form is significative. Male is more slender than female .更多还原
