四大家鱼,青鱼 Mylopharyngodon piceus、草鱼 Ctenopharyngodon idellus、鲢鱼 Hypopht-halmichthys molitrix、鳙鱼 Aristichthys nopilis,是我国淡水主要养殖对象。具有生长快、饵料来源广、单位产量高等优点。由于以往只能在江河流水环境中产卵繁殖,生产受到很大限制。经我国水产科学工作者反复实践,不断探索,掌握了四大家鱼的繁殖规律,取得了人工繁殖的成功,为淡水养殖的鱼苗来源开辟了新途径,推动了我国淡水渔业的发展。 Four major domestic fish, Mylopharyngodon piceus, Ctenopharyngodon idellus, silver carp Hypopht-halmichthys molitrix, Aristichthys nopilis, is the main freshwater aquaculture in China. With fast growth, wide source of feed, the advantages of high yield per unit. Because in the past only spawning in rivers and streams of water environment, production has been greatly restricted. Repeated practice by our aquatic scientists, continue to explore and master the reproductive laws of the four major domestic fish, artificial breeding success has been achieved for freshwater fish breeding sources opened up new avenues to promote the development of freshwater fisheries in China.
