衡阳市现有百亩左右水面的小型水库1300多座,养殖水面7万多亩,约占全市总水面的15.6％,是发展淡水养殖的重要途径之一。现年均单产徘徊在20公斤左右,增产潜力很大。如何利用小型水库的优越条件,发展淡水养殖,特提出几项增产措施供探讨。一、小型水库的特点小型水库的特征是:库周稻田多,河床平,坡斜缓,面集中,跨界少,水不深,范围小,易管理。同时,库水循环快,生物作用强,天然饵料丰富,鱼类生长快,我市常宁新塘、祁东梅塘等水库单产超过150公斤的经验,是认真贯彻落实了党的有关经济政策,改进
Hengyang currently has more than 1,300 small reservoirs with a surface area of about 100 mu and aquaculture area of over 70,000 mu, accounting for 15.6% of the total surface water of the city. It is one of the important ways to develop freshwater aquaculture. Annual average output hovers around 20 kilograms, a great potential for increase production. How to make use of the superior conditions of small reservoirs to develop freshwater aquaculture? First, the characteristics of small reservoirs Small reservoirs are characterized by: library weeks more rice paddies, river bed slope, inclined slow, concentrated surface, less cross-border, water is not deep, small, easy to manage. At the same time, the reservoir water cycle is fast, biological role is strong, natural food rich, fast fish growth, the city Changning Xintang, Qidong Mei Tong reservoirs and more than 150 kilograms of production experience is conscientiously implement the party’s economic policies and improve
