摘要
对小型水库的养鱼模式、网箱配置、水库施肥等高产技术进行了综合研究。1992年,试验水库41座,面积351公顷,总产成鱼1283.6t,平均每公顷产3657kg,净产3310.5kg,比开发前提高4.27倍;每公顷纯利8804.25元,投入产出比1:1.92。1993年6月专家鉴定认为,本研究居国内同类技术开发的领先水平。
Studies were carried out on fish culture model,fingerlings releasing,net cages setting and manure spreading. In 41 experimental reservoirs with the total area of 351 ha the total output of the adult fish was 1283.6t,the Per mu yield of 220.7kg on average, ratted 3. 27times than the threeyears'yield before exploitation.The net profit was 586. 95yuan Per mu and the ratio of input and output was 1: 1. 92,The result,appraised in June, 1993,was in the ital at home,eompared with the result of the same study subject.
