Oxygen depletion happens in aquatic environments as dissolved oxygen becomes reduced in concentration endangering aquatic organisms living in the system. Fish can be seen hanging at the water surface, sometimes gulping air.
Aeration is required to raise oxygen levels once depletion has been detected. This can be achieved by deployment of mechanical aeration devices or by the addition of hydrogen peroxide under controlled conditions.
