The culture of aquatic animals and plants under controlled or semi-controlled conditions is the world’s fastest-growing food-producing sector. Many technologies are being innovated to date to enhance the assembly. But Recirculation Aquaculture System (RAS) is a far better option, with minimal environmental impacts, thanks to low effluents production from aquaculture ponds. It is a technology of farming aquatic organisms by reusing the water in production based on the use of mechanical and biological filters. RAS also minimizes water usage, disease occurrence, acts as a water treatment system, improves feed conversion, and shortens the production cycle. Overall, the principal components of the RAS and therefore the potential of this technique to be utilized in modern aquaculture have been discussed in this review paper to help scholars to understand the basic principle and its application with its merits as a water treatment system. Further research on the development of the RAS system with low price and high energy efficiency should be conducted. Moreover, the implementation of RAS in the natural systems and earthen pond may also benefit the farmer.
