| 摘 要： | 测定了饱食1/3、饱食2/3和饱食水平下黄颡鱼的生长和饲料利用情况。结果显示:①随着摄食水平上升,湿重、干重、脂肪、蛋白质和能量特定生长率显著上升,其中湿重特定生长率与摄食水平呈直线相关,干重、脂肪、蛋白质和能量特定生长率与摄食水平呈对数曲线相关;②饲料转化效率、蛋白质和能量储积率随摄食水平的上升而显著上升,但蛋白质和能量储积率在饱食2/3和饱食水平时差异不显著。

| Abstract: | A trials were conducted at 3 ration levels (1/3satiation, 2/3 satiation and satiation) to investigate the effect of ration level on the growth and feed utilization of Pseudobagrus fulvidraco. The results showed that: ①with increasing ration level, specific growth rate of wet weight increased significantly in linear style, and specific growth rate of dry weight, lipid, protein and energy increased significantly in curvilinear style; ②with increasing ration level, feed conversion efficiency,recovered protein and energy increased significantly, while recovered protein and energy were similar between group satiation and 2/3 satiation. |
