池塘养鱼大面积高产技术推广试验

在总面积为２１６５ｈｍ＾３的池塘中，试验推广４种养鱼模式，池塘设置小网箱等技术，取得大面积高产结果：平均亩产６５２９．５ｋｇ／ｈｍ＾２，平均盈利１２０１０．５／ｈｍ＾２，比推广前３年平均亩产提高５５．９％，鉴定认为，在养殖面积，单产水平及综合管理技术等方面达我国北方同类水域的先进水平。

On Spreading Technique for High Yield in Large Area of the Pond Fish Culture

In the ponds with the total area of 2165 h four models of fish culture were tested to spread technique for high yield.After taking the technical measures such as setting small net cage in the pond,etc,the high yield of the adult fish was harvested in the large area:the per h yield was 6529.5 kg(per mu yield 435.3 kg)on average,and the average profit was 12010.5 yuan/h(800.70 yuan/mu),raising 55.9% compared with the prespreading three years' per unit average yield.The result,appraised by experts,reached the advanced level in the same water area in the aspect of culture area,unit yield and comprehensive management technique,etc.
