摘要
１９９５年在２５亩鱼池中进行了鱼鸭混养试验，净收入７万元，亩均收入２８００元，是单一养鱼的７～８倍。证实北方地区鱼鸭混养是可行的，鱼种密度以４００～５５０尾／亩为宜，每亩鱼池放鸭７０～８０只较好。
An experiment was conducted on mixed culture of fish and duck in the fish pond with the area of 25 mu in 1995.The experimental result showed:the net income was 70 thousand yuan,2800 yuan per mu on average,7～8 times as much as monoculture of fish.It proved that it is feasible for mixed culture of fish and duck in North China,but the releasing density of fish and duck is as good as 400～500 fingerlings per mu and 70～80 duck per mu respectively.
