摘要
研究了本溪太子河流域洛氏鱥（Phoxinus lagowskii Dybowsky）个体繁殖力及其与生物学指标的关系。结果表明：其个体绝对繁殖力为601 s.1～15775.0粒，个体相对繁殖力 FL 为75.8～1132.9粒/cm ， FW 为64.7～602.3粒/g ；个体绝对繁殖力与体长、净体重、卵巢重呈正相关，与成熟系数、肥满度负相关，但与成熟系数相关关系不显著；个体相对繁殖力 FL 与成熟系数、肥满度相关关系不显著，与各生物学指标正相关；个体相对繁殖力 Fw 除了与肥满度呈负相关外，与其余各生物学指标正相关，但与成熟系数、肥满度相关关系不显著。
The individual fecundity of Phoxinus lagowskii in the Taizi River of Benxi city,and the relationship between the individual fecundity and the biological character indexes were studied.The results showed that the individual absolute fecundity(F)of Phoxinus lagowskii varies from 601.1to 15775.0eggs.The individual relative fecundity of body length(FL)ranges from 75.8to 1132.9eggs/cm,and the relative fecundity of body weight(Fw)ranges from 64.7to 602.3eggs/g.The individual absolute fecundity and the individual relative fecundity FL were significantly positive correlated to body length,net body weight,coeficient of maturity and ovary weight.The individual absolute fecundity was negatively corelative to maturity coeficient and condition factor,and had no obvious relationship with maturity coeficient.The individual relative fecundity FL was also negatively corelative to maturity coeficient and condition factor,and had no obvious relationship with maturity coefficient and condition factor.The individual absolute fecundity Fw was negatively correlated to condition factor and was directly corelated to the other biological character indexes.The individual relative fecundity Fw also had no obvious relationship with maturity coefficient and condition factor.
