我国劳动人民在长期的池塘养鱼实践中积累了丰富的经验,形成了传统式养鱼技术,而养鱼单产却不高。目前虽然有许多地方采用了增氧机等机械设备,提高了产量,减轻了劳动强度,但是鱼的单产仍不理想。因为鱼产量的提高与池塘生态环境有密切关系,生态和经济方面的一些因素往往限制了单产的进一步提高。江苏常州市多种经营管理局吴志大工程师等同志研究成功了“生态系流水养殖技术”,综合地解决了这一问题。为此,特请吴志大工程师对“生态系流水养殖技术”进行专题讲座,全文分六讲:一、生态学原理;二、养殖工程;三、泵站设计;四、养殖工艺;五、经济效益和生态效益;六、展望。本刊拟分四次载完,欢迎广大读者对此讲座提出宝贵意见。
The working people in our country have accumulated rich experience in the practice of long-term pond fish farming, forming a traditional fish-farming technique, while the production of fish farming is not high. At present, although there are many places using aeration machines and other machinery and equipment to increase production and reduce labor intensity, fish yields are still not ideal. Because of the close relationship between increased fish production and the pond ecosystem, some ecological and economic factors often limit the further increase in yields. Changzhou City, Jiangsu Province, a variety of management Wuzhi Da engineers and other comrades successfully studied the “ecosystem of aquaculture technology” to comprehensively solve this problem. To this end, please enlist Wu Zhida engineers on the “ecosystem of aquaculture technology” for a special lecture, the full text is divided into six: First, the ecological principles; Second, aquaculture projects; Third, pumping station design; Economic and ecological benefits; The publication is divided into four sub-finished, welcome to readers for their valuable advice on this lecture.
