| 摘 要： | 对兰州鲇个体繁殖力进行了研究,结果表明:兰州鲇的个体绝对繁殖力(F)为2.4~33.8千粒,其相对繁殖力(FL,Fw)分别为64.0~571.0粒/cm和7.0~33.4粒/g.兰州鲇的个体绝对繁殖力与体长呈线性关系,即F=1.390 3L-49.234(R2=0.928 4,P<0.001).个体绝对繁殖力与体重呈幂指数关系,即F=0.000 2W1.72(R2=0.812 7,P<0.001).兰州鲇个体的绝对繁殖力(F)和相对繁殖力(FL)与年龄、成熟系数、卵径呈正相关.

| Abstract: | The individual absolute fecundity of Silurus lanzhouensis was investigated.The results showed that the individual absolute fecundity of Silurus lanzhouensis was between 2.4 and 32.8 thousands eggs and the individual relative fecundity FL and FW were 64.0～571.0 eggs/cm and 7.0～33.4 eggs/g respectively.The relationship between absolute fertility(F) and body length(L) presented a linear line:F=1.390 3L-49.234(R2= 0.928 4 P<0.001).Absolute fertility(F) and body weight(W)presented a curve line:F=0.000 2 W1.72(R2= 0.812 7,P<0.001).Absolute fertility and relative fertility(FL) of Silurus lanzhouensis were positively related with age,sex maturity coefficient and egg diameter. |
