将体长2.48~3.00cm,平均体长2.64cm;体重2.37~3.16g,平均体重2.68g的鞍带石斑鱼鱼苗在水温17.2~24.6℃、海水盐度31.2条件下进行室外水泥池培育。采取逐渐添加淡水降低盐度至18~19;以鱼体重4%~6%日投喂量投喂用鱼浆或鲜虾浆与幼鳗粉料混合制成的湿性饲料的方式。经过52d的培育,鱼苗体长增至4.7~6.8cm,平均体长增长3.12cm/尾,增长率121.44%;体重增至5.73~8.64g,平均体重增重4.84g/尾,增重率180.60%。培育存活率97.4%。
The larvae of grouper with the body length of 2.48 ~ 3.00cm and the average body length of 2.64cm, the body weight of 2.37 ~ 3.16g and the average body weight of 2.68g were cultivated in outdoor cement pool under water temperature of 17.2 ~ 24.6 ℃ and seawater salinity of 31.2. Take the gradual addition of fresh water to reduce the salinity to 18 ~ 19; the fish fed 4% ~ 6% of the daily feed with fish pulp or fresh shrimp paste and mixed wet meal made of wet feed. After 52 days of cultivation, the body length increased to 4.7-6.8cm, the average body length increased by 3.12cm / tail, the growth rate was 121.44%, the weight increased to 5.73-8.64g, the average weight gain was 4.84g / tail, the weight gain rate was 180.60 %. Breeding survival rate of 97.4%.
