研制了泥鳅配合饲料,初步探析了泥鳅饲料中水虻幼虫添加量对小、中泥鳅摄食率和成活率的影响。结果表明,泥鳅对水虻幼虫具有与鱼粉相似明显的摄食性和诱食性,可用于部分替代鱼粉使用 ,但摄食率和成活率均随添加量的增加而下降;适于小、中泥鳅的水虻最佳添加量为9 %～11 %。
The loach feed was developed and the effects of the larvae feeding on the feed intake and survival rate of loach and loach were analyzed. The results showed that loach had obvious similar feeding habits and attractability to fish meal, and could be used for partial replacement of fish meal. However, the feeding rate and survival rate of loach decreased with the increase of the added amount. Water suitable for small and medium loach虻 The best dosage is 9% ~ 11%.
