| 摘 要： | 本文报导了在半咸水池塘中梭鱼仔幼鱼的摄食习性．梭鱼仔幼鱼在全长20毫米前以摄食浮游动物为主；20毫米后，由于浮游动物数量急剧减少，摄食的种类迅速增多．梭鱼仔鱼适口的开口饵料是桡足类的无节幼体和桡足幼体．适口饵料生物的宽度为口宽的25—71％。梭鱼稚鱼昼夜摄食强度有一定的节律：日出前后开始摄食，日落前饱食指数最高；夜晚基本不摄食。

| Abstract: | Results on feeding habits of mullet fry in brackish water ponds applied withmunures for producing natural feed is obtaind. The mullet fry below 20 mm in totallength feed mainly on zooplanktons, beyond 20 mm, the feeding habit is rapidlydiversified. The palatable starting feed of mullet fry is the nauplius and small cope-pods. There is a diurnal rhythm for feeding intensity of mullet fry. Feeding beginswith sunrise and stops at sunset, maximum fullness is attained before sunset. The fryessentially not take food at night. Therefore. feeding activity of mullet fry may relys,on visual acuity. |
