Recirculated Aquaculture Systems

Recirculated Aquaculture Systems (RAS) are closed-loop water systems that enable fish farming to be carried out efficiently and with minimal environmental impact. RAS uses various filtration and water treatment technologies to ensure that water is reused within the system. This helps to conserve water and reduce pollution, making it a sustainable way to farm fish. It is also more energy-efficient as the use of oxygen pumps and aerators are significantly reduced. RAS is being increasingly used in countries with limited access to water and in areas that face regulatory or environmental constraints. It is also used to farm species such as salmon and tilapia, both of which are important sources of human nutrition.
