目前,我国池塘养鱼饵料基本上是以米糠、麸皮、豆饼或青草单一投喂,转换效率不高。例如使用米糠或麸皮养鱼,生产一斤鱼需6斤多饵料;用豆饼喂养,也需要3斤。从饵料的蛋白质利用看,用米糠或豆饼投喂,生产一公斤养殖鱼,分别需要蛋白质820克或1,227克。这与国外生产一公斤养殖鱼需530～600克蛋白质相比,浪费太大。 At present, China’s pond fish bait is basically a single feeding rice bran, bran, bean cake or grass, the conversion efficiency is not high. For example, the use of rice bran or bran fish, produce a pound of fish need more than 6 pounds of food; with bean cake feeding, also need 3 pounds. From the perspective of the protein utilization of the bait, one kilogram of farmed fish is fed with rice bran or bean cake, respectively requiring 820 grams of protein or 1,227 grams of protein. This is a kilogram of foreign fish production needs 530 ~ 600 grams of protein, waste too much.
