Did you know that we could provide a healthy environment for fish with very less fresh water? Usually, we think that we need high amount of fresh water for fish to live and survive, but with the advancement in the technology we have something called as RAS or Recirculating Aquaculture System where fish can live in an extremely natural habitat and with very less water, this helps in saving water as well as providing a healthy environment for the fish to live and survive.
Recirculating Aquaculture System, is considered as one of the best techniques in recent times which has the ability to reduce the need for fresh, clean and huge amount of water for fish to live in. To have an economic and commercial balance, we need to have high stocking densities for the fish to live in. We also observe that there are various kinds of researches and studies going on in order to understand and get the hands-on experience of RAS in the market. These studies also help in understanding if RAS is a viable form of intensive agriculture.
To Maintain RAS water treatment process we also have special methods which could help us understand and work on it accordingly, considering all the factors, biofiltration, oxygenation, ph control, temperature control, solid removal and biosecurity are the major factors to be considered when RAS is taken into picture. We have consequences and also related information which we need to understand while taking up any step with regard to the same. Oxygen plays a major role for any living being on our planet, having said this it’s extremely important for us to provide the required percentage of oxygen for the fish as well. Biosecurity is also important as it deals with the external influences when considered RAS as an economical and commercial process.
We also have certain advantages and disadvantages to be understood about RAS, the main advantage of RAS would be the ability to maintain a naturally living habitat in extremely less water, having an opportunity to closely monitor the life and growth of fish. Reduced land needs as we have high stocking densities, site selection flexibility and independence. While these being the advantages the other disadvantages are high amount of investments, high operating costs and also need for an experienced person to monitor and understand the system.
