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。
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.
