环境友好的水产养殖业——零污水排放循环水产养殖系统

Environmental friendship aquaculture──Zero discharge integrated recirculating aquaculture systems

目前的水产养殖业正逐步向集约化、农牧化并以提高产量、质量和生态效益的方向发展 ,渔业生态环境受到高度重视。作者综述了与水产养殖有关的一些环境问题 ,以及可用于集约式工厂化养殖的水产养殖环境工程与技术 ,并介绍了以发展环境友好的水产养殖业为目标 ,运用水生生态学原理从工程、工艺角度出发开发零污水排放的水产养殖模式系统。最后提出了集约化水产养殖中有待关注的一些问题。

Aquaculture is developed towards to land-based integrated farming and intensive pasture, and tends to elevate yields, quality and ecological benefit of production. Aquacultural environment is regarded highly. In this paper, we reviewed the environmental aspects in relation to aquaculture, and discussed the environmental engineering techniques being available to industrial recirculating aquaculture systems. The zero discharge aquaculture system that will be based on aquatic ecological principles is recommended, which is aimed to develop aquaculture with environmental friendship. The aspects of intensive aquaculture that must be paid attention are suggested.
