Recirculating Aquaculture Systems (RAS) overview
Aquaculture farming, especially fish farming, is a rapidly growing industry that is increasingly facing pressure to practice sustainable farming to reduce its ecological footprint. One of the recommended methods is Recirculation Aquaculture Systems (RAS).
Compared to traditional farming, recirculation systems offer two advantages: reduced environmental impact and cost-effectiveness.
In a recirculating aquaculture system, water is constantly treated, filtered, and reused to control environmental factors in high-density fish farming using minimal land and water.
Unlike other aquaculture production systems, it is an intensive-density fish farming system. As opposed to traditional methods of raising fish outdoors in open ponds and raceways, this method involves rearing fish indoors and outdoors in controlled environments.
In recirculating systems, feed quantity and quality, as well as the type of filtering, play a critical role in the management of the system. A recirculating system can use a wide range of filtration technology. Still, it aims to remove metabolic wastes, excess nutrients, and solids from water while maintaining good water quality.
