| 摘 要： | 对池养条件下瓦氏黄颡鱼(Pelteobagrus vachelli)早期发育阶段的摄食节律进行了研究。结果表明:每日5:00~9:00及17:00~21:00瓦氏黄颡鱼的饱满指数相对较高,15:00~17:00最低,表明瓦氏黄颡鱼属于晨昏摄食型;在仔鱼出膜后的第5、10、15、20、25和30天瓦氏黄颡鱼的日摄食率分别为44.79%、33.72%、23.21%、19.92%、16.58%和10.27%,呈逐渐下降趋势。

| Abstract: | The feeding rhythm of Pelteobagrus vachelli in early life was studied in fish pond.The fullness index of P.vachelli was relatively higher at 5:00～9:00 and 17:00～21:00,and it was relatively lower at 15:00～17:00 in one day.Therefore,it showed that the daily feeding rhythm of P.vachelli appeared to morning-dusk feeding model.The daily feeding rates were 44.79%,33.72%,23.21%,19.92%,16.58%,10.27% at 5th,10th,15th,20th,25th,30th day respective,which had a gradually decrease trend. |
