分布:主要分布于宁夏、陕西、山西、河南、山东境内的黄河干流及其重要支流河段内。目前黄河鲤鱼资源已明显衰退。例如,50年代,在三门峡、灵宝、洛阳、巩义、郑州及开封等地均有专业捕捞队在黄河里捕鱼,月捕鱼量600-1150公斤/船,其中黄河鲤可占总重量的45-50%。而到1981-1982年,同样的作业方法在同一季节的月捕获量也不超过125公斤/船,特别是黄河鲤鱼的产量下降更为严重,年捕捞量还不足1万公斤,并且年龄与个体均减小。

For example, in fifties, there were major fishing teams fishing in Yellow River in Sanmenxia, Lingbao, Luoyang, Gongyi, Zhengzhou and Kaifeng, the volume of fishing 600-1150 kg per boat, the number of Cyprinuscarpio can take up 45-50% of the total weight, but by1981-1982, the same method of operation in the same season, they caught month yields nor more than 125 kg / boat, especially in the Yellow River carp production dropped more serious, the annual catch of has less than 10,000 kg, and the age and the individual were reduced.
