| 摘 要： | 对长江江津段中华沙鳅(Botia superciliarisG櫣nther)的耳石,年龄和生长进行了初步研究。结果显示:几种年龄鉴定材料中,适宜中华沙鳅的年龄鉴定材料为耳石,能准确反映其年龄状况。体重与体长的回归方程为:W=0.021L2.8409(r=0.9404);该江段中华沙鳅的生长方程为:体长:Lt=12.50001-e-0.3851(t+1.1062)];体重:Wt=29.09441-e-0.3851(t+1.1062)]2.8409。

| Abstract: | This paper carries out a first step research into the otolith,age and growth of Botia superciliaris Günther in Jiangjin segment of Yangtze River.The material which is suitable to authenticate the age is otolith,because it can accurately reflect the age of Botia superciliaris Günther.The regressive equation of weigh and length is W=0.021L2.8409(r=0.9404) and the growth equations are Length: Lt=12.50001-e-0.3851(t+1.1062)];Weight: Wt=29.09441-e-0.3851(t+1.1062)]2.8409. |
