Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen and are a more severe condition of hypoxia. The US Geological Survey defines anoxic groundwater as those with dissolved oxygen concentration of less than 0.5 milligrams per litre. This condition is generally found in areas that have restricted water exchange.

The utility model relates to aquatic products breeding equipment technical field discloses an oxygen -increasing equipment for aquaculture, including drive assembly, conical water leaf subassembly and float frame subassembly, spare carry the drive assembly of reduction gearbox and drive motor, reduction gearbox can effectively adjust power output speed, reduce the influence of load fluctuation to power transmission, ensure that conical water leaf subassembly rotates stably, reduce the oxygen -increasing efficiency fluctuation of power instability, prolong the service life of equipment. Conical water leaf subassembly adopts the design of conical bucket body and circumferential distribution blade, can effectively reduce the resistance, is not easy to reduce the speed because of load, simultaneously, conical bucket body can guide the water flow to form the spiral ascending movement track in the rotation process, expands water body agitating range, can promote the exchange of surface layer oxygen -rich water and deep layer oxygen -deficient water.
