| 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。

| Abstract: | Alto gether 240 specimens o f Monop t er us albus w ere studied by examining
the to tal leng th and weight fo r age determinat ion. The specimens were collected f rom Tuman
Road Bazar f rom Febr uary in 1996 to Januar y in 1997. Age determinat ion w as made by
oto lith ( sagit ta) , ver tebra and hyo id-arch bo nes. The result s indicate tha t the hyo id-arch
bo nes are mo re suitable fo r a ge determinat io n o f M. albus. Grow th studies w ere made by
means of sca les metho d. Tw o commonly fo rmulae W= aLb a nd W= a+ bL wer e a pplied to
compute the leng th-weig ht relat ionship o f M . albus. The fo llowing expressio ns wer e der
