| 摘 要： | 2010年5～9月从长江支流沱江收集性成熟宽体沙鳅个体,研究了其个体生殖力及其与多项生物学指标的关系。实验鱼共76尾,由2+、3、4龄鱼组成。其绝对生殖力(F)为414～9625粒,平均3230粒;体长相对生殖力(FL)为50～837粒/cm,平均324粒/cm;体重相对生殖力(FW)为21～789粒/g,平均227粒/g;绝对生殖力、体长相对生殖力和体重相对生殖力与成熟系数呈幂函数相关,回归方程为:F=177.99GSI0.9872,FL=20.315GSI0.9592,FW=13.957GSI0.9542;绝对生殖力和体长相对生殖力与体重呈幂函数相关,回归方程为:F=9.4876M1.9425,FL=2.2684M1.6597。

| Abstract: | The individual fecundity and the relationship between individual fecundity and a variety of biological indices of Botia reevesae were studied.76 adult female specimens which are 2+,3 and 4 years old,were collected from the Tuojiang River,a tributary river of the Yangtze River from May to September,2010.The absolute fecundity(F) is 414~9625,averaged 3230.Length relative fecundity(FL) is 50~837,averaged 324.Weight relative fecundity(FW) is 21~789,averaged 227.The relationship between absolute fecundity(F),len... |
