摘要/Abstract

摘要： 采用人工配制海水（盐度为10），自配粉状饲料（蛋白含量45％），在水温24~29℃的范围内，对2 200尾体重3~4 g的点带石斑鱼幼鱼进行培育试验。经过67 d培育，鱼体体重达到32.7~35.0 g，约增加9倍，日均增重量达0.44~0.46 g，特定生长率为3.24~3.57％/d；平行养殖试验结果显示成活率分别为70％和80％，饲料系数分别为0.93和0.86；养殖过程完全实现不换水，不用药的节水型和健康型模式。

Abstract: Abstract: We made experiments to feed 2,200 young Epinephelus malabaricus with purely artificial feedingstuff in artificial sea water. The salinity was 10‰, the water temperature was controlled between 24—29℃. After 67 day’s growth, the weight of the young Epinephelus malabaricus increased by three times and its daily weight increase rate reached 9.34 ％. The results of the same two experiments show that survival rates are 70 ％ and 80 ％, the feedingstuff coefficients are 0.93 and 0.86. We have realized a water saving and healthful ecological feeding model with no water changed and no medicine used in the whole process of feeding.
