Recirculation aquaculture systems (RAS) repr esent a new and unique way to farm fish. Instead of the traditional method of growing fish outdoor s in open ponds and raceways, this system rears fish at high densities, in indoor tanks with a "c ontrolled" environment. Recirculating systems filter and clean the wa ter for recycling back through fish culture tanks. New water is added to the tanks only to ma ke up for splash out and evaporation and for that used to flush out waste materials. In contrast, many raceway systems used to grow trout are termed "open" or "flow through" systems because all the water makes only one pass through the tank and then is discarded.
