摘 要:为了解蛇鮈的肥满度情况,在牡丹江流域渤海镇江段采集了79尾蛇鮈,测量其体长体质量特征,运用回归分析对蛇鮈雌雄样本进行分析.结果表明,雄性蛇鮈的体长-体质量关系式为W=0.0000040532 L^(3.269)(R^(2)=0.799),雌性为W=0.0000000584 L^(3.589)(R^(2)=0.952),雌雄混合统计时体长-体质量关系式为W=0.0000012885 L^(3.522)(R^(2)=0.915).雄性肥满度略高于雌性,但两者无显著性差异,雌雄群体均为异速增长.In order to understand the fatness of Saurogobio dabryi,79 individuals were collected from the Mudanjiang River and their body mass characteristics were measured,in this paper,male and female samples were analyzed by regression analysis.The results showed that the relationship between body length and body weight of male Saurogobio dabryi was W=0.0000040532 L^(3.269)(R^(2)=0.799),female was W=0.0000000584 L^(3.589)(R^(2)=0.952),and the relationship between body length and body weight of male and female was W=0.0000012885 L^(3.522)(R^(2)=0.915).The fatness of male was slightly higher than that of female,but there was no significant difference between them,both male and female grew at an allometric rate.
