现代渔业养殖的生产成本60％以上是饲料成本。有资料表明仅有25％-35％的饲料物质通过形成鱼体成分而被利用,很大部分未被摄食或形成粪便及其它代谢废物而进入水域,这样便造成饲料的浪费,使饲料系数提高,同时还易造成水质的污染。那么如何降低饲料系数,提高饲料的利用率以降低生产成本?让我们从影响饲料系数的因素中寻找对策。 More than 60% of the cost of producing modern fisheries is feed costs. Data show that only 25% -35% of feed ingredients are utilized by forming fish body components and most of them are not taken in or formed into feces and other metabolic waste and enter the waters, resulting in waste of feed and increased feed efficiency , But also easy to cause water pollution. So how to reduce the feed coefficient, improve feed utilization to reduce production costs? Let us from the factors that affect the feed coefficient to find countermeasures.
