在商品鱼养殖过程中,饲料费占养殖成本的40%以上,降低饲料成本是增加养殖效益的关键。应用光合细菌,把农家作物秸秆(如麦秆、稻草、玉米秆、花生壳等)生产成为鱼的生物饲料,不但养殖效果显著提高,而且饲料成本大幅降低。光合细菌能产生多种促长因子,促免疫因子、辅酶 Q 等,促进幼体生长发育,在鱼类养殖上有如下作用:(1)减少有毒、有害物质在水体中的含量,消除“死鱼”现象;(2)增加水体中含氧量,减少、
In the process of fish farming, feed costs account for more than 40% of the cost of farming, reducing feed costs is the key to increasing the efficiency of farming. The use of photosynthetic bacteria to produce farm animal straw (such as straw, straw, corn stalks, peanut shells, etc.) into a fish’s biological feed not only significantly increases the breeding effect, but also significantly reduces feed costs. Photosynthetic bacteria can produce a variety of growth factors, immune factors, coenzyme Q, etc., to promote larval growth and development in fish farming has the following effects: (1) reduce the toxic and harmful substances in the water content, eliminate the “dead fish ”Phenomenon; (2) increase the oxygen content of water, reduce,
