我省小(二)型水库一般具有引水方便,水源较为丰富,水面积、水体相对较小,便于管理精养的优点,汉中地区就有同类型水库120座,水面6480亩。我省自1983年推广中小型水库磷氮化肥养鱼以来,小(二)型水库平均亩产50多 kg,最高也仅有200多kg。为了探索中小型水库特别是小(二)型水库渔业生产潜力,在养殖方式上有新的突破,使产量迈上更高台阶,城固县水产技术推广站和城固县渔场在有关部门的支持下,在沈家槽水库和邱山湾水库大胆进行了养殖鲤鱼的高产尝试。通过两年实践,取得了亩产鱼分别为952kg 和933kg,亩均纯利分别为574元和869元的好成绩,现将他们的经验
Small reservoirs in our province generally have the advantages of convenient water diversion, abundant water sources, relatively small water area and water body, and convenient management and intensive maintenance. There are 120 reservoirs of the same type in Hanzhong area and the water surface is 6480 mu. Since the promotion of small and medium sized reservoirs of phosphorus and nitrogen fertilizer in 1983, small reservoirs have produced an average of more than 50 kg per mu and a maximum of only 200 kg. In order to explore the potential of small and medium-sized reservoirs, especially the small (second) type reservoirs, there is a new breakthrough in breeding methods and the output will reach a higher level. The fishery technology promotion station in Chenggu County and the fishing grounds in Chenggu County With support, high-yielding attempts were made to raise common carp in Shenjialu Reservoir and Qiushanwan Reservoir. After two years of practice, we have achieved good results of 952kg and 933kg of mu fish respectively with a net profit of 574 yuan and 869 yuan per mu, respectively. Now, their experience
