摘 要：
探讨了3种不同饲料,即黄粉虫(A)、颗粒饲料2号(B)、颗粒饲料3号(C)对丝足鲈幼鱼生长的影响。用3种饲料养殖丝足鲈幼鱼30 d,进行生长对比试验。结果表明:在蛋白质效率上,试验组A(329.21%)>试验组B(145.09%)>试验组C(98.97%);在增重率上,投喂黄粉虫的试验组A增重最多,增重率为64.09%,其次是试验组B,增重率为52.23%,试验组C增重率最小,增重率为28.50%,其变化趋势与蛋白质效率的变化相同。综合蛋白质效率、增重率、饵料系数和经济成本等指标来看,可以选用2号颗粒饲料作为丝足鲈幼鱼的日常养殖饲料。

摘 要：
Effects of three different feeds on the growth of juvenile of Osphronemus goramy were discussed. Three kinds of feeds(Tenebrio Molitor,special pellets No.2,special pettets No.3)were used to feed one-year-old Osphronemus goramy for 30 days to observe the effects of these different kinds of feeds on the growth. The result showed that :protein efficiency of Group A was 329.21%,which was the hightest of the three groups,the Group B was 145.09%,the Group C was 98.97%. The changes of the grouth rate among different groups followed the similar pattern as that of the protein efficiency. Growth rate of the Group A was significantly higher than the others,followed by the Group B and the Group C was the least. The growth rate in the experiment is 64.09%,52.23%,28.50% respectively. Through comprehensive consideration of protein efficiency,growth rate,feed conversions and economic indicators,No.2 special pellets can be choosen as the daily feed for juvenile of Osphronemus goramy.
