Nanobubbles Pave Way for Sustainable Oxygen Supply to Fish Farms in Iran

A nanobubble device produced by a company active in the nanotechnology field has yielded significant results in reducing aquatic losses, improving fish growth, and saving energy consumption after three months of use in a fish farm.

Kaveh Badamegan, the manager of a fish farm that has started using the technology recently, elaborated on his experience of working with the nanobubble system.

“We decided to use this technology in our farm. It has now been about three months since the installation of the nanobubble system, and during this time we have witnessed significant positive effects,” he said.

Noting that the fish mortality has significantly decreased in his farm, Badamegan stated, “The reliable performance of the device in emergency situations has also been satisfactory and in times of power outages, this device has been able to provide the required oxygen to the water for about two hours without the need to start the electric motor.”

Studies in Iran have shown that, given the potential of nanobubbles, it is possible to double the annual production of aquatic products with the help of this technology.

At present, equipment related to nanobubble technology is produced domestically in Iran and this equipment is used in different industries like water purification, agriculture and fisheries. The use of nanobubble technology in some cities and villages has contributed significantly to the improvement of water quality in Iran. Nanobubble technology has been used in numerous greenhouses throughout the country, and this technology has been applied in the greenhouse sector too.

One of the areas that has a very high potential for utilizing nanobubble technology is the aquaculture industry. Nanobubble technology can have advantages for this sector like creating supersaturated oxygen conditions in ponds, ideal and uniform distribution of oxygen, and improving water quality. Reducing losses and significantly increasing production are other benefits of using nanobubble devices in aquaculture industry.

The annual production of aquatic products in the country's 25,000 aquaculture farms is about 500,000 tons, and if all these farms are equipped with the nanobubble system, the production will increase 100 percent.
