我市位于黑龙港流域,常年干旱少雨,淡水资源比较缺乏。为了提高有限的淡水水面的利用率,促进我市淡水渔业的发展,我们在沧州市郊进行了尼罗罗非鱼池塘高产养殖试验,并取得良好效益,每667m~2产鱼达到1664.5kg,创我市最高水平。现将有关技术管理作法总结如下: 1 材料与方法 1.1 试验池 试验池一个,面积1333m~2,池深3.5m,30米浅水井一眼提供水源,配有1.5kw叶轮式增氧机一台。 The city is located in the Heilongjiang River Basin, perennial drought, lack of freshwater resources. In order to improve the utilization of limited freshwater surface and promote the development of freshwater fishery in our city, we carried out high-yielding experiment of Nile tilapia pond in the suburbs of Cangzhou, and achieved good benefits, reaching 1664.5kg per 667m ~ 2 producing fish The city’s highest level. Now the technical management practices are summarized as follows: 1 Materials and methods 1.1 Test pool A test cell, an area of ​​1333m ~ 2, pool depth 3.5m, 30 m shallow wells at a glance, with a 1.5kw impeller aerator.
