黄颡鱼生长特征与食性的研究

studies on the Growth Characteristics and Food Habits of Pseudobagrus fulvidraco (Richardson)

本文研究了黄颡鱼的生长特征及食性,得到黄颡鱼体长与体重的关系式为W=3.571×10^(-4)L^(2.379),体长生长方程为Lt=237.002(1-e^(-0.280(t+0.127)),主要食物为虾类,其次为小鱼、鱼卵等。

the growth characteristics and food habits of pseudobagras fulvidroco have been conducted, The results are as follows. The body weight -body length relationship can be expressed by W =3. 571×10-4L2.379, and the general pattern of its body length growth can be expressed by Von Bertalanffy growth equation; Lt=237. 002 (1- e-0.280(t+0.127)). The main foods of the P. fulvidraco are shrimps, small fishes and fish eggs.
