| 摘 要： | 研究了黄颡鱼早期发育阶段摄食的昼夜节律性及日摄食率。结果如下：黄颡鱼仔稚鱼摄食具有明显的昼夜节律性。胃平均饱满指数在仔鱼前期、仔鱼后期和稚鱼期分别于21：00、3：00、6：00达最高峰，均于15：00达最低值。不同发育阶段的日摄食率分别为：仔鱼前期69.96%，仔鱼后期28.84%，稚鱼期10.00%。

| Abstract: | The feeding rhythm and the daily feeding rates of pelteobagrus fulvidraco in early life history are Stucliecl.The results are as following:day and night feeding rhythm is observed apparently in larval and juvenile stages.The peak index of fullness lies at 21:00 in pre-larval stage,3:0 0 in post-larval stage and 6:00 in juvenile stage.The daily feeding rates varies with the development.in those three stages,the daily feeding rates are 69 96% ,28 84%and10 00%respectively. |
