Studies on nursery technique of the young fish of Epinephelus coioides

本文报道了点带石斑鱼幼鱼中间培育的实验结果。幼鱼中间培育的关键,是根据鱼苗的规格定期及时分苗。实验使用2批鱼苗,采用人工配合饲料喂养,经45d的培育,平均全长分别由27mm和28mm增至75.7mm和82.1mm。平均体重从0.22g和0.23g增加到7.5g和10.7g。平均日增长1.1mm和1.2mm,日增重0.16g和0.23g。成活率为94.3%和94.9%。

The paper reports the results of the studies on nursery technique of the young fish of Epinephelus coioides. The crucial importance of the nursery technique was separate the young fish according to there sizes in time. It took 45 days for rearing 2 broods of the fish. A sort of artificial formula food was used to rear the fish. During the experimental period the average total length of 2 broods of young fish increased from 27mm and 28mm to 75.7mm and 82.1mm respectively, while the average body weight of them increased from 0.22g and 0.23g to 7.7g and 10.7g respectively. The survival rate of the young fishes was 94.3~94.9%.
