鳜鱼是终身食活鱼虾的狭食性鱼类,目前尚无法使它主动摄食配合饲料,这不仅成为大规模养殖鳜鱼的首要难关,而且使鳜鱼营养生理的研究难以进行。 在测定鳟鱼饲料消化率时,为了精确控制饲料摄入量,减少损耗,国外学者曾采用过强制填喂饲料的方法。但国内在鱼类或其他动物的营养研究中,尚未见采用这种方法的报道。为了研制食性特殊、价 Nautilus is a long-term live fish live shrimp prawn fish, at present it can not make it take the initiative to feed with compound feed, which not only become the primary difficulty in large-scale cultivation of anchovy, but also makes the research of nutrition and physiology of anchovy difficult to carry out. In the determination of trout feed digestibility, in order to precisely control the feed intake, reduce losses, foreign scholars have used mandatory feeding feed method. However, the domestic research on the nutrition of fish or other animals has not been reported by this method. In order to develop food special, price
