摘要: 用湿颗粒饲料(试验组饲料)与小杂鱼(对照组饲料)对点带石斑鱼进行为期65d的饲养试验。结果表明,试验组与对照组点带石斑鱼的尾平均日增重差异不大,平均饲料系数分别为1.43、4.75,点带石斑鱼增重1kg所需饲料成本分别为8.01元和9.50元,试验组比对照组每公斤鱼增重节省饲料成本1.49元;试验组与对照组点带石斑鱼平均内脏比、平均丰满度、肌肉粗蛋白含量、粗脂肪含量等差异不显著(P0.05)。

Abstract: A 65-day feeding trail was conducted to evaluate the difference between Oregon moist pellet (trial group) and trash fish (control group) fed to Epinephlus malabaricu. The results indicated that there were no significant differences in the average daily gain (ADG) between the trial group and the control group, the average feed coefficient (FC) was 1.43 and 4.75 respectively, the feed cost of 1kg gain for Epinephlus malabaricu were ￥ 8.01 and ￥ 9.50 respectively, and the cost saved ￥ 1.49.There were no significant differences (P0.05) in the average ratio of internal organs for Epinephlus malabaricu, the fatness coefficient, the contents of crude protein and crude fat in muscle. So it was feasible for Epinephlus malabaricu to be fed with Oregon moist feed.
