摘要
为探讨芜萍配合饲料的养鱼效果 ,进行了网箱养鱼试验 .结果表明 ,在蛋白质含量相等和其他主要成分相近的情况下 ,鱼用配合饲料中加入 30 %或 40 %芜萍干粉养殖 1龄和 2龄草鱼 ,或加入 2 0 %~ 30 %芜萍干粉养殖鲤鱼、工程鲫、淡水白鲳 ,其增重率明显高于对照 。
The results obtained from the experiment showed that,when contents of protein and other main formulations in fodder were close to each other,one year old and two year old grass carps growth rate was significantly higher than that of the contrast group,and the fodder coefficiency was obviously lower than that of the contrast group. This was because they were fed with mixed fodder containing 30% or 40% dry powder of Wolffia arrhiza. This also happened to engineer crucian carp,colossome brachypomum and carp when they were fed with mixed fodder containing 20%~30% dry powder of Wolffia arrhiza.
