前言池塘养鱼对为城市人民生活服务,支援社会主义革命和建设具有重要意义。而大幅度提高单位面积产量则是发展城郊养鱼的关键。近年来有些省、市创造了不少经验,家鱼养殖亩产达2000斤,混养非洲鲫亩产达3133.4斤,净产2263.5斤(无锡,1976,1977)。为了摸索池塘养鱼高产稳产的规律,在省、市水产局和各级党委的关心支持下,我们从1974年开始,以七一大队“新建塘”作实验池(图1),面积10.3亩,开展以非洲鲫为主体鱼的精养高产实验,对放养密度、品种搭配、饵料、水质以及养殖技术等进行了综合实验,获得初步成效,产量逐年提高,1977年亩产达3115,9斤,净产2983.7斤,并初步摸索出一些池塘精养高产的经验,发现一些值得进一步探讨的问题。兹将实验情况报告于下,请批评指正!
Introduction Pond fish culture is of great importance to serving the urban people’s lives and supporting the socialist revolution and construction. The substantial increase in yield per unit area is the key to the development of suburban fish farming. In recent years, some provinces and municipalities have created a lot of experience. The mussel production per mu is up to 2,000 kg, and the polygrowth of African crucian carp is up to 3133.4 kg and the net output is 2263.5 kg (Wuxi, 1976, 1977). In order to explore the law of high and stable production of fish in the pond, with the concern and support of provincial and municipal aquatic bureaus and party committees at all levels, we started with experimental group 1 (a) , Carried out intensive crucian carp production experiments, the stocking density, variety mix, feed, water quality and breeding technology conducted a comprehensive experiment, obtained initial results, the output increased year by year, in 1977 the yield reached 3115, jin , A net yield of 2983.7 kg, and initially explored some of the pond intensive high-yielding experience and found some worthy of further exploration. I will report the experimental situation in the next, please correct me criticism!
