During these adjustments, the water outflow from the Aquatector was diverted outside the test tank and fresh water was added to the test tank to maintain a static water level. After 10 min. Reoxygenation of the test tank was then recorded until readings were stable. Oxygen transfer rates and efficiencies were calculated from the regression model at ambient conditions for each test. Solid lines are regression lines plotted on every fourth data point recorded.

This level of oxygenation would be adequate for a limited water flow through a recirculation system or in a small flow-through system in which oxygen requirements are fairly stable. Aquatectors may also be effective in supplementing downstream oxygen requirements in flow-through culture of salmonids. Emergency aeration mechanisms for commercial-sized warmwater culture ponds must be capable of quickly adding oxygen to large volumes of water.
