We report on the generation of ultra-fine air bubbles (≤ 380 nm) through our experience with the water in oil emulsion generation technology and discuss potential implementation for this technology in the fish farming industries. Nano air bubbles in water/liquid bodies are miniature gas bubbles with unique physical properties such as an ability to last for extended periods of time (months), high gas solubility/difusability into liquids, high internal pressure and an ability to sink rather than rise and burst at the water surface. It has been well known that high oxygen gas solubility of microbubbles is beneficial for the oxygenation of hypoxic tissues and environments; nanobubbles in comparison are much more efficient in this regards. Some preliminary investigations have reported the advantages of using nano air and/or oxygen bubbles in several medical and environmental applications and in plant and animal growth. The use of such nanobubbles in fish farms therefore is expected to increase fish growth rate and promotes the cleaner environment with less organic waste accumulation at the bottom of the farms cages or tanks and lower chemical and biological oxygen demand levels in the wastewater generated in these activities.
