[目的]设计、建设一套满足我国当前水产养殖业工业化、节约化需求的养殖系统。[方法]对现有养殖池塘进行改造,结合工程化施工,建造3条流水槽;利用气提式推水装置营造流水养鱼的效果;通过沉淀池及微滤器作用将养殖鱼类代谢废物收集、压缩、重新利用;在套养鱼区利用滤食性鱼类进行水质净化。[结果]每条流水槽均可单独饲养不同种类、不同规格的鱼类;养殖池塘水循环利用,整个养殖周期内达到污水零排放;经处理后的水质达到水源水标准。[结论]该养殖系统具有养殖水体循环利用、可进行高密度精养、降低生态环境压力等优点,是一种高效、生态、环境友好型的养鱼新技术。
[Objective] To design and construct a set of breeding system to meet the current industrialization and saving needs of aquaculture in our country. [Method] The existing aquaculture ponds were rebuilt and constructed with 3 engineering watercourses. Airlift type water-pushing device was adopted to create the effect of running water fish. Metabolic wastes of farmed fish were collected through sedimentation tank and micro-filter , Compressed, re-use; the use of filter-feeding fish in the set of fish-farming areas for water purification. [Result] Each flow tank could feed different types of fish with different specifications separately. The pond water was reused and circulated to achieve zero discharge of sewage within the whole breeding cycle. The treated water quality reached the water source water standard. [Conclusion] The aquaculture system had the advantages of reusing aquaculture water, being able to carry out high density intensive cultivation and reducing the pressure of ecological environment. It is an efficient, ecologically friendly and environmentally friendly fish farming technology.
