A recirculating aquaculture system (RAS) is a method of fish farming that uses a closed-loop system to continuously filter and recycle water. It is an environmentally sustainable approach that minimizes water usage and reduces the release of pollutants into the environment. In a RAS, fish are raised in tanks or ponds, and the water is continually circulated through a series of filtration systems to remove waste products and maintain optimal water quality. The filtered water is then returned back
