【摘要】 研究了矛尾复瞺虎鱼个体生殖力及其与生物学指标的关系,结果表明:个体绝对生殖力为3052～67896粒,个体相对生殖力Fl为234.0～1867.0粒/cm,Fw为16.8～1260.1粒/g。个体绝对生殖力与体长、净体重、卵巢重呈直线相关,与肥满度负相关,与成熟系数相关关系不显著;个体相对生殖力Fl除了与成熟系数相关关系不显著,与各生物学指标正相关;Fw除了与成熟系数和肥满度呈正相关外,其余均呈负相关。更多还原

【Abstract】 The individual fecundity of Synechogobius hasta(Temminck &Schlegel) in the East China Sea and the relationship between the individual fecundity and the biological character indexes were studied.The results showed that individual absolute fecundity varied from 3052 to 67896 eggs, the individual relative fecundity Fl (F=egg number,L=body length) varied from 234.0 to 1867.0 eggs/cm,and Fw (W=net body weight) varied from 16.8 to 1260.1 eggs/g. The individual absolute fecundity was linearly and directly correlative to body length, net body weight,ovary weight. The individual absolute fecundity was negatively correlative to maturity coefficient and had no obvious relationship with condition factor. The individual relative fecundity Fl was significantly correlated to these biological character indexes except for maturity coefficient.The individual absolute fecundity Fw was directly correlated to condition factor and maturity coefficient and was negatively correlated to the other biological character indexes.更多还原
