青鱼肉质好,肉间细刺少,味道鲜美,营养价值高而被视为上等食用鱼。而且病害少,生长速度快,一般鱼种增重在7倍以上,其养殖经济效益远高于其他常规品种。但青鱼为肉食性鱼类,主要摄食底栖动物、昆虫幼体、螺蚬、蚌类、米虾等。长期以来,因饲料问题未能解决,只能作为搭配养殖品种而限制了饲养量。随着全价颗粒饲料的开发应用,主养青鱼已成为现实。
Good quality meat of melanogaster, small sparse meat between the meat, delicious, high nutritional value and is considered the first-class food fish. And less disease, fast growth, the general weight gain of more than 7 times the breeding of its economic efficiency is much higher than other conventional varieties. However, the carp is a carnivorous fish, feeding mainly benthic animals, larvae, snails, mussels, rice shrimp and so on. For a long time, due to feed problems can not be resolved, only as a breeding species with limited feeding. With the development and application of full-price pellet feed, the main culture of herring has become a reality.
