INTRODUCTION TO RECIRCULATING
AQUACULTURE SYSTEM
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.
