• An innovative fish farming method that conserves water and reduces
environmental impacts
• A highly intensive form of aquaculture
• It works on the principal of zero or almost zero water exchange

3. RAS is now being adapted by aqua
farmers across the world
In fact many fish farmers are now
designing their own RAS, instead of
the standard design, given by
suppliers

4. 1
Water exchange, anywhere from
100% water exchange once in 24
hours to once in a week
Drum filter to remove
physical impurities
THERE ARE 4 MAIN ELEMENTS IN RAS

Bio filter to balance the
chemicals , reduce ammonia,
phosphates etc

5. play a pivotal role in the success of RAS
Biofilters
• Backbone of any RAS, biofilters are responsible for maintaining water quality
• Biofilters contain bacteria that convert the sludge and waste, breakdown the
nitrite and ammonia and keep the water clean
• They are nature’s filters
• Biofilters need aeration to keep the bacteria growing and functioning well. Hence
aeration is of paramount importance in biofilters
AirOxi offers intensive aeration system for biofilters

7. Apart from supporting beneficial
bacteria, aeration also directly
benefits fish health in RAS
aquaculture systems
Fish require well-oxygenated water to
breathe and grow optimally. If oxygen
levels drop, fish can become stressed,
leading to reduced immunity and
increased susceptibility to diseases

8. RAS is the heart of the system
In conclusion, a good RAS system needs a well-designed biofilter and
proper aeration needs to be given to this filter. This is what separates
RAS from other technologies of aquaculture
