Oxygen for Fish Farming
Controlling the dissolved oxygen content to improve the profitability of your farm
In fish farming, the quality of the water and the environment of the fish are determining factors. Controlling the dissolved Oxygen content in the water is essential in aquaculture or during the transport of live fish.
To improve the profitability of your farm, Air Liquide recommends injecting pure oxygen into the water, a more effective alternative to traditional air tank aeration technologies.

Oxygen Supply
A wide choice of safe supply methods adapted to the level of your consumption.
- For moderate consumption: deliveries of liquid oxygen stored in mobile tanks or in bundles of compressed oxygen cylinders.
- For small volumes, you can buy your bottle from a distributor
- For the oxygenation of fish farming ponds: delivery of liquid oxygen by tank truck in a large tank made available by Air Liquide and managed automatically.
- For very high and regular nominal flow rates: dedicated oxygen production units, on customer site, can be proposed after in-depth study.
Security of Supply
Free yourself from the constraints of managing your supplies thanks to telemetry.
- Gas level monitoring in the tank automatically triggers the oxygen supply
- Real-time consultation of parameters relating to the installation (gas flow rates, pressure in the networks, etc.)
- Consultation of technical notices and safety data sheets
Oxygen for the transport of live fish
A pressurised gas cylinder or a liquid source can be used to be installed on the vehicle. It will diffuse oxygen at the right concentration in the bottom of the tanks and transport crates containing the fish.
Advantages
✓ Allows long distance transport (possibility of export)
✓ Increase in the fish load in the tanks, reduction in the cost of transport per kg of fish.
✓ Freshness is maintained and losses avoided during the journey.

Service
Our specialists provide you with rapid and personalized responses to your logistics and process needs. They give you the benefit of more than 50 years of experience in project management on complete systems:
Evaluation of oxygen consumption used Configuration of your installation: sizing of the tank, the vaporizer, design of the distribution network, connections, etc. Advice on oxygenation equipment and regulation of the oxygen injected into the pools.
RAS and Sustainability
RAS, or Recirculated Aquaculture System, uses > 99% recycled water for high density fish cultures. Its significant contribution towards sustainability comes from excellent water efficiency – using the same water to continuously culture fish in higher densities and quantities – without polluting the ocean.
In a Recirculating Aquaculture System (RAS), our OXYFLOW ® can be installed on the main pipe. It does not require any complementary piping, nor pumps. It allows large energy savings.
-
More fish with limited water used
-
Protect fish from seasonal water change
-
Stable fish production all the year
-
High fish density achievable

OXYFOX
OXYFOX is an oxygenator designed for aquaculture. This device has a very high capacity of dissolution of oxygen, using few energy. OXYFOX has been created to treat important water flows, and to cover the needs of a series of ponds, or even of the whole fish farm. OXYFOX both uses the energy of a water fall and the hydrostatic pressure in the depth of a well. The combination of these two factors unables to reach high D.O contents, with maximum oxygen efficiency.
OXYFLOW
OXYFLOW ® is an oxygen generator designed for aquaculture. This device has a very high capacity of dissolution of oxygen into the water, using no, or very low, energy. Each OXYFLOW ® is manufactured according to a specific working pressure, for use in freshwater or seawater. The higher the working pressure is, the higher the outlet oxygen concentration is. The higher the water flow is, the larger the diameter and the greater the height of the OXYFLOW ® are. A complete range of OXYFLOW ® allows to answer all the needs. In a Recirculating Aquaculture System (RAS), OXYFLOW ® is installed on the main pipe. It does not require any complementary piping, nor pumps. It allows large energy savings.
