摘 要：
从渤海采集卵巢发育到Ⅳ和Ⅴ期的矛尾复鰕虎鱼32尾,采用重量法进行了生殖力的研究。结果表明:矛尾复鰕虎鱼为分批产卵类型,卵子呈卵圆型,卵径0.726mm±0.291mm;矛尾复鰕虎鱼的个体绝对生殖力为33 609±14 022粒,单位净体重生殖力为439.92±139.50粒/g,单位体长生殖力为1 176.08±227.08粒/mm。矛尾复鰕虎鱼个体绝对生殖力与体长、体宽、体重、净重、性腺重及肥满度相关关系密切,而与成熟系数相关关系不密切;体长相对生殖力与除成熟系数以外的其他生物学指标相关关系一般,与成熟系数相关关系不密切;净重相对生殖力与体长、体重、净重、性腺重、肥满度关系密切,与其他生物学指标相关性不强。

摘 要：
32 specimens that ovaries developed to Ⅳ,Ⅴ period were collected in Bohai,fecundity was studied by weight method.The results showed that:Synechogobius hasta was the batchspawner,the egg was oval type,,egg diameter was 0.726±0.291 mm.The individual absolute fecundity of Synechogobius hasta was 3609±14022eggs,the fecundity per net body weight was 439.92±139.50eggs/g,the fecundity per body length was 1176.08±227.08 eggs/ mm.The individual absolute fecundity of Synechogobius hasta presented closely positive relationship with body length,body wedth,body height,body weight,net body weight and relative fatness,poor relationship with maturity coefficient;the fecundity per body length had moderate relationship with other biological indicators but maturity coefficient,poor relationship with maturity coefficient;the fecundity per net body weight had closely relationship with body length,body weight,net body weight,gonad weight and relative fatness,poor relationship with other biological indicators.
