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.

- High production of quality fish on a relatively small area.
- Reduced risk of diseases.
- Low mortality rates.
- Continuous control
- No environmental influences
- Intake and effluent reducing to the minimum.
- Treatment of discharge water
disadvantages of Recirculation aquaculture systems
- Depending on regular power supply and control.
- Start-up capital for building, technical installation and running cost
