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

What is recirculating aquaculture systems (RAS) RAS - a recirculating aquaculture system is a practically closed production circuit system, where more than 90% of the technological water is purified, saturated with oxygen and returned or reused continuously in production tanks. The produced waste products (solid waste, ammonium and CO2) are removed or converted into non-harming products by the technological system. By recirculating the water, the water and energy requirements are limited to a mi
