FISH FARMS / AQUACULTURE

If you’re in the aquaculture industry, you’re very familiar with the benefits of O₂ — for fish growth, health, and maximizing population density. AirSep has been providing 95% oxygen generation systems to fish farms around the world for over 20 years.

Like humans, fish and other marine animals required oxygen to survive. With the prevalence of fish farms, the “farmers” must insure their livestock gets proper oxygen to survive. Before fish farming was done on an industrial scale, the farmers would fence off an area of water at the edge of a lake to raise their catch. With industrial oxygen generators, farmers now have the ability to raise fish in man-made pools of oxygenated water. The benefit to the farmer is higher stock densities in a smaller area and faster fish growth.

AirSep offers Reliability, simplicity, and ease of maintenance, particularly in the remote locations where most aquaculture is located. A few of our oxygen generator’s benefits are relativity & simplicity.

How It Works

A side stream of water from the raceway, pond or tank is pumped at elevated pressure through a venturi nozzle, where oxygen is injected. The water becomes saturated with oxygen and is then distributed through high velocity mixing nozzles along the bottom surface of the raceway, pond or tank. Oxygen flow rates can either be manually regulated or automatically controlled using a dissolved oxygen (DO) analyzer and probe. By ‘closing the loop’ with a signal that is fed back from the DO meter, the oxygen system can be turned on and off automatically, as needed. DO is gaseous oxygen that is dissolved into water that fish directly absorb through their gills and skin for respiration. The DO concentration is measured in parts per million (ppm) and a saturation of 70% or concentration of 5 or 6 ppm is essential for stable growth in fish.
