摘要
研究了养殖条件下黑尾近红鲌的生长规律，结果表明：体长（L）与鳞径（R）呈直线相关L=6．4355R＋3．4337（r=0．9983）；体重（W）与体长（L）呈指数函数关系形=0．0093L3．2546（r=0．9921）。应用各龄逆算体长、体重均值，求得生长方程L1=45．9643[1-e^-0.3238（t＋1.2687）]，Wt=2393．2495[1-e^-0.3238（t＋1.2687）]3.2546。体重生长曲线的拐点ti=2．38龄，拐点处的体长为Li=31．86cm，体重为Wi=726．18g。根据生长指数分析得出1-2龄的黑尾近红铂体长、体重生长最快。
The growth of Ancherithroculter nigrocauda Yih Et Wu in culture conditions was investigated in this study. Regression analysis showed that body length was correlated positively with the radius of tile scale （L=6. 4355R ＋ 3.4337 （r=0.9983）） and exponentially with weight （ W = 0. 0093L^3.2546（r = 0. 9921））. The growth equation, Lt=45.9643 [1-e-0. 3238（t＋1.2687）] and Wt= 2393. 2495 [ 1-e^-0.3238（t＋1.2687）]^3.2546, was sought by the application of the inverse operator TSE body length and average weight. The inflexion of the weight growth curve was at the age of 2.38 and at this age the body length and weight were Li = 31.86cm, Wi=726.18g respectively. Ancherithroculter nigrocauda Yih Et Wu at 1-2 age grew fastest according to the analysis of the growth index.
