在浮式海水网箱(1.5m×1m×1.5m)中养殖石斑鱼幼鱼(9.4±0.1g),在等氮(52% CP)基础上进行以发酵豆粕和普通豆粕替代鱼粉的实验, 为期56天.结果显示:在石斑鱼饲料中添加14%发酵豆粕,其增重率、特定生长率(SGR)、饲料效率和蛋白质效率与对照组没有显著性差异(P>0.05),以后随着发酵豆粕添加量的上升,这些指标都显著下降(P<0.05).在同样替代水平下,添加21%发酵豆粕组,增重率,SGR,饲料效率和蛋白质效率都比添加20%豆粕组高(P<0.05),表明对海水肉食性鱼类来说,发酵豆粕是一种比豆粕更优良的蛋白源.用折线模型分析增重率随白鱼粉替代水平的变化关系,结果表明在石斑鱼配合饲料中,发酵豆粕替代白鱼粉的最适量为10%.从实际生产的经济效益出发,建议在饲料中添加14%发酵豆粕,对石斑鱼的生长和鱼体组成不会造成显著影响.

A 56-day feeding trial was conducted to evaluate the potential of replacing white fish meal (WFM) with fermented soybean meal (FSBM) and soybean meal (SBM) in experimental diets for juvenile grouper Epinephelus coioides of initial weight 9.4±0.1g. Six isonitrogenous diets were formulated to contain 52% protein and 12% lipid. WFM was replaced by FSBM at four inclusion levels of 28%, 21%, 14% and 7%(diets 1-4).
