Recirculating Aquaculture System (RAS) provide a constant and controlled environment for the fish, allowing for optimal and fully manageable production of Catfish, Telapia and other fish species. Recycled water is very warmer than natural water. RAS operated by filtering water from the fish tanks, so it can be used within the tank. The filtration system operate continuously, keeping the water clean and providing a healthy environmental for the fish.

One of the most important unit processes in RAS production technology was Ammonia control & waste solids removals. Pelleted diets used in aquaculture production consist of protein, carbohydrates, fat, vitamin and mineral packs and water.
