Oxygen in Aquaculture

Fish farms can increase stocking densities and improve yields by up to one third by using Oxair’s Pressure Swing Adsorption oxygen applications. These introduce oxygen in its pure form directly to fish tanks.

Oxygen in aquaculture for larger and healthier fish
Applying the same technology used in vital medical facilities, Oxair’s PSA gas generators enable much greater quantities of fish to be farmed in a comparatively small volume of water and cause the fish to grow larger as well. Aquaculture installations have shown that, for every 1kg of oxygen pumped into the water, 1kg of fish growth results. Our generators are currently being used to farm salmon, eel, trout, prawn and snapper, among other varieties, at a global level.

Cost savings
Oxair’s generators are cost-effective to run and, compared with paddlewheel equipment, increase the partial pressure and natural saturation limit in the water by a factor of 4.8 compared to aeration with mere air. Farms can make further savings too, as fish health and metabolism are improved, so less feed is needed. Salmon that are farmed in this way are healthier and tastier as well, containing three times the amount of essential fatty acids and developing a better flavour.

Quality water, quality fish
As the quality of the water determines the quality of the fish, you can also use Oxair’s equipment to create the ozone needed in water recycling reactors to sterilise the used water, which is then treated with UV light before being recirculated into the tank.

Oxair’s designs focus on meeting your exact requirements, including reliability, ease of maintenance, safety, and plant self-protection.
