摘要
用黄鳝的耳石、脊椎骨和舌骨三种材料相对照，对其年龄进行了鉴定，认为舌骨是黄鳝年龄鉴定比较理想的材料，并首次提出尾舌骨也可以作为年龄鉴定的材料。分析了体长、体重的分布，分别用幂函数关系和直线回归方程计算体长与体重的关系式，并进行比较。
Altogether 240 specimens of[WTBX〗 Monopterus albus were studied by examining the total length and weight for age determination. The specimens were collected from Tuman Road Bazar from February in 1996 to January in 1997.Age determination was made by otolith (sagitta), vertebra and hyoid arch bones. The results indicate that the hyoid arch bones are more suitable for age determination of M. albus. Growth studies were made by means of scales method.Two commonly formulae W=aL b and W=a+bL were applied to compute the length weight relationship of M.albus. The following expressions were derived from:W=8.3613L-300.3 (R 2=0.8908);W=0.0003L 3.2941 (R 2=0.9482).
