| 摘 要： | 本文报道产于沱江的大口鲇Ｓｉｌｕｒｕｓｍｅｒｉｄｉｏｎａｌｉｓ成鱼阶段食性和生长等生物学资料。食物以鱼类为主，４龄前生长迅速，体长与体重相关关系方程式为：Ｗ＝１１．５５０９ＢＬ２．９８０１，ｒ＝０．９９１４，原因可能与沱江饵料丰富有一定关系。

| Abstract: | Some biological characteristics of the growth and feeding habits of the adult Saurys meridtonalis in Tuojiang River were reported. They feed mainly on fishes and grow fast before 4 years old. The equation of relative relationship between the length and weight is W = 11. 5509 BL2.9801 r= 0. 9912, df = 82, (probably) because the food in Tuojiang Rivr is very abundant. |
