在长江胭脂鱼开口饵料的研究中我们发现,长江胭脂鱼开食时更喜食鲜活饵料,用人工配合饲料投喂开口率明显低下。但在高密度集约化的养殖条件下,完全依靠天然鲜活饵料养成也不太可能做到,而用配合饲料养殖具有使用安全方便、供应稳定等优点,也是一个必然趋势。那么,用鲜活饵料做 In the study of fishes in the open mouth of the Yangtze fishes, we found that when the fishes in the Yangtze River started to eat more fresh feed, the feeding rate was significantly lower with artificial feed.

It is also an inevitable trend to use synthetic feed to breed safer, more convenient and stable supplies. Well, with fresh food to do
