摘要
加州鲈鱼在池塘养殖条件下,当水温21.5～25℃时,仔鱼从第5日龄开始摄食,开食期(5～9日龄)饵料为盘肠蚤和粉红粗毛蚤等小型枝角类。11日龄食性转变为捕食鱼苗,并相互残食。幼鱼期至成鱼期,主要以鱼苗、鱼种、野杂鱼虾为食。性成熟期,摄食仍很旺盛。
This paper deals with the experiments On feeding habits of Micropterus salmonoides cultured in earthen ponds. At the temperature of 21. 5-25℃, the larval began to feed five days after hatching and the initial food was small cladoceran such as chydorus, macrothrix andthen unicellular algae, rotifers and so on. The conversion of food began on the 11th day, and from than on they took fish fry, fish fihgerling, small fish of various kinds and shrimp as their food. However, the feeding intensity of micropterus salmouoides is still high even in sex maturation stage.
