摘 要:采用0,10% ,20% ,40%和60 %比例的全价粉末饲料与冰鲜杂鱼混合 ,配制成湿颗粒饲料 ,投喂牙鲆(Paralichthysolivaceus,T.&S.) ,进行工厂化养殖试验。结果证明随着添加全价粉末饲料量的增加 ,饲料系数逐渐降低 ,鱼体增重率逐渐增加 ,在鱼体防病、成活率、体色方面 ,投喂添加粉末饲料的湿颗粒饲料都明显优于单一的冰鲜杂鱼 ,其中 ,4号饲料在养殖成本方面 ,每公斤鱼的饲料投入比鲜杂鱼节省1.In this experiment, we used moist pellet to feed flounder in cement ponds. Moist pellet was made by 0, 10%, 20%, 40% and 60% of formula powder feed mixed with small frozen fish. Results showed that feed coefficient decreases and fish weight gain increases with formula powder feed rate increase in moist pellet. The fish survival rate,the prevention of disease and the pigment of the fish fed with moist pellet content formula powder feed were better than that only fed with small frozen fish. No. 4 pellet was the lowest price of all pellets for breed aquatics cost.No.4 is cheaper than small frozen fish hy 1.26 yuan to feed product 1 kg fish.
