According to our research from internet, several books and farm visits, we will try to give our reader detail knowledge about RECIRCULATING AQUACULTURE SYSTEM. In our blog we will discuss everything about RECIRCULATING AQUACULTURE SYSTEM (RAS).

                               -----  DEFINATION OF RAS-----

1. Recirculating Aquaculture is a technique for raising water borne animals in a closed (usually indoor) system which minimizes water consumption, provides maximum control of the livestock’s environment, and reduces the risk of exposure to parasites, disease, and predators.

      2.  Recirculating Aquaculture Systems (RAS) operate by filtering water from the fish (or shellfish) tanks so it can be reused within the tank. This dramatically reduces the amount of water and space required to intensively produce seafood products. The steps in RAS include solids removal, ammonia removal, Co2 removal and oxygenation.

3.Recirculating aquaculture systems are indoor, tank-based systems in which fish are grown at high density under controlled environmental conditions. Generally, farmers adopt a more intensive approach (higher densities and more rigorous management) than other aquaculture production systems.

4.Recirculating aquaculture systems can be used where suitable land or water is limited, or where environmental conditions are not ideal for the species being cultured. This type of aquaculture production system can be used in marine environments; however, it is more commonly used in freshwater environments.

5. Indoor Recirculation Aquaculture System are land-based fish farms, which allows all year round control and delivery of fish. Whether the facility will use fresh water, brackish or a marine water, an R.A.S works on the same principles. The system can achieve optimal temperature and optimal and stable production all year round, independent of seasonal variation, location, climate and environment.
