我县马陆乡机械化养鱼场于1983年,在机械化高密度的流水养鱼池中饲养尼罗罗非鱼,通过人工增氧第一年试养就获得每平方米54.53斤的高产记录,同年又运用成鱼塘进行轮捕轮放双季鱼饲养原理,在机械化养鱼的水泥池内进行二季饲养试验,取得了每平方米64.56斤的好收成,单产比对照池49.2斤提高31.2%。84年县水产技术推广站与马陆乡机械化养鱼场正式承担了饲养双季罗非鱼的高产试验项目,现将高产试验情况总结如下。(一)材料与方法1.水泥圆池:每口池直径为7米,面积38.4m~2,共二口计76.8m~2,池深四壁高1.3
In 1983, Malu Township mechanized fish farm in our county reared Nile tilapia in a mechanized and high-density running fish pond and obtained a yield record of 54.53 kg per square meter through the first year trial of artificial aeration. In the same year, Also used into the fish pond rounding wheel release of double-season fish feeding principle, in mechanized fish ponds for second season feeding experiments, achieved 64.56 pounds per square meter of good harvest, yield 49.2 pounds more than the control pool increased 31.2%. 84 years County Fisheries Technology Promotion Station and Malu Township mechanized fish farm officially assumed the breeding of double-season tilapia high-yield test project, the high-yield test situation is summarized as follows. (A) Materials and methods 1. Cement round pond: each pond diameter of 7 meters, an area of 38.4m ~ 2, a total of 76.8m ~ 2, deep pool wall height 1.3
