摘　　要：采用鳞片作为研究的年龄鉴定材料.鳞片上年轮主要为3种.疏密型和间隙型年轮主要在整个前区,均较为明显,切割型年轮主要在侧区.鳞片的鳞径(R)与体长(L)的关系为L=4.241 7+45.021R,体长(L)与体重(W)的关系为W=0.009 6L3.073 6.用3种生长模型拟合的生长,结果表明,Gompertz生长模型对生长的拟合效果最好,VB生长模型拟合的效果最差.From November 2005 to September 2006,631 specimens were collected in the Beijiang River,Guangdong for the studies on growth of Hemiculter leucisculus,scales used for age determination.The correlation formula of the body length(L,cm) and scale radius(R,cm) is: L=4.241 7+45.021R,and of body length(L,cm) and weight(W,g) is: W=0.009 6L3.073 6.Three kinds of formulas were used for fitting the length and weight growth of H.leucisculus.The results show that the Gompertz growth formula is the best precise model to ...
