选配3组虹鳟鱼种饲料配方,通过网箱养殖进行了对比试验,结果表明:1#配方饲料与2#、3#配方饲料有显著差异,2#、3#配方饲料差异不显著;1#配方饲料含粗蛋白37.0%、粗脂肪22.3%、可消化能1.76 MJ/kg,饲养鱼种平均成活率为96.85%,鱼种平均尾重167.2g,总增重931.2 kg、增重12.67倍,饲料系数为1.29。建议生产上使用1#配方饲料。 The results showed that there was a significant difference between 1 # formula feed and 2 # and 3 # formula feeds, while there was no significant difference between 2 # and 3 # formula feeds. 1 # The formula feed contains 37.0% of crude protein, 22.3% of crude fat, digestible energy of 1.76 MJ / kg, average survival rate of breeding fish species is 96.85%, average tail weight of fish species is 167.2g, total weight gain is 931.2 kg and weight gain is 12.67 times , Feed coefficient of 1.29. The proposed production of 1 # formula feed.
