Recirculating aquaculture system (RAS)

A Recirculating Aquaculture System (RAS) is an advanced method for growing fish in controlled environments. It continuously filters and recycles the water, removing waste and maintaining optimal water quality. This system minimizes water use compared to traditional methods, often recirculating over 90% of the water. RAS allows precise control over factors like temperature, oxygen, and waste removal, resulting in healthier fish and less environmental impact. It's suitable for urban or land-based setups, making aquaculture more sustainable and efficient, especially where water resources are limited.
