摘　　要：为了解红鳍东方鲀仔鱼对轮虫的摄食量和昼夜摄食规律,我们对孵化16天的仔鱼进行轮虫日摄食量的试验。结果表明,16日龄的仔鱼,平均全长7.015mm,轮虫日摄食量为360个/尾,昼夜比例为79.0%和21.0%,在9:00到11:00及17:00到19:00出现摄食高峰。The daily consumed numbers of rotifer of the larval fish Takifugu rubripes,and the feeding rhythm of the larvae were studied.The feeding intensity,feeding rate and the daily consumed numbers of rotifer were calculated.The results showed:the average total length of 16-day-old larvae was 7.015mm and the daily consumed numbers of rotifer were 360/one fish.The percentage of day and night consumed numbers were 79.0% and 21.0%.Tow feeding peaks appeared during 9:00～11:00 and 17:00～19:00.
