摘　　要：选用5种不同矿物饲料分别进行草鱼种饲养试验，其结果以草鱼成活率、增重率和饲料系数三项指标为依据进行综合分析，结果表明：不同矿物饲料的草鱼增重率问差异极显著，以矿3（麦饭石）组最高，比对照组提高28．65％；各组饲料系数间差异显著，最优者亦是矿3组，较对照组降低21．64％，因此矿3（麦饭石）可以作为草鱼复合矿物盐预混料的优良绿色载体。Feeds including five kinds of mineral respectively were used to optimize for grass carp seeds. A synthetically analysis were carried out according the three quotes of survival rate, weight gain rate and feed efficiency. The results were Feeds including different minerals had remarkable divergence at weight gain rate, The group including mineral No3 { MF （Granite） } was the best. It increased 28.65% compared with the contrast group. Feeds efficiency between different groups had notable diversity, The excellent also was the mineral No3 group, it decrease 21. 64% compared with the contrast group. So that mineral No3 { MF（Granite） } can be acted as the fine ＂green＂ carrier for compound mineral additive of grass carp.
