An agricultural unit and use thereof relates to: a tank system adapted to provide a combined aquatic environment for raising aquatic animals in aquaculture and cultivating plants in hydroponic culture, whereby excretions of the aquatic animals are released directly into the aquatic environment so as to produce nutrients for the plants; and an electrochemical device; wherein the electrochemical device is operable in an electrolysis mode to produce hydrogen and oxygen while consuming electrical energy provided by a source of electrical energy; wherein the electrochemical device is further operable in a fuel cell mode to produce electrical energy and heat by oxidizing the produced hydrogen; and wherein the electrochemical device is operatively coupled to the tank system so as to transfer at least part of the produced heat and the produced oxygen to the aquatic environment.

An oxygen emitter which is an electrolytic cell is disclosed. When the anode and cathode are separated by a critical distance, very small microbubbles and nanobubbles of oxygen are generated. The very small oxygen bubbles remain in suspension, forming a solution supersaturated in oxygen. A flow-through model for oxygenating flowing water is disclosed. The use of supersaturated water for enhancing the growth of plants is disclosed. Methods for applying supersaturated water to plants manually, by drip irrigation or in hydroponic culture are described. The treatment of waste water by raising the dissolved oxygen with the use of an oxygen emitter is disclosed.

The present invention discloses an oxygenation device for an aquaculture tank group and a control method, and belongs to the technical field of aquaculture equipment. The oxygenation device for the aquaculture tank group includes a controller, a speed regulator, a fan and a buffer tank which are successively connected; an outlet of the buffer tank is connected with a main gas guiding tube, the main gas guiding tube is branched into a plurality of branch gas guiding tubes, a tail end of each branch gas guiding tube is connected with an oxygenation hole, each oxygenation hole is placed in a corresponding aquaculture tank, each aquaculture tank is placed in a pond, automatic oxygenation control over numerous flowing water aquaculture tank groups may be realized, and oxygen supply of aquaculture tanks may remain stable automatically when a water level of a water area of the pond changes due to weather variations or human factors. Moreover, a use method of the device is simple, and after an aquaculture plan is established, oxygenation of each aquaculture tank only needs to be adjusted once. In addition, the device is low in cost, expensive meters such as an adjusting valve and a dissolved oxygen sensor are reduced, and the oxygenation device for the aquaculture tank group is easy to popularize actually.

The present invention relates to a degassing device and an aquaculture system with such a degassing device. The degassing device includes perforated rotating blades.

An aquarium including a first water chamber providing a habitat for aquatic species, a second water chamber, wherein the second water chamber is fluidly coupled to the first water chamber, and a third water chamber, wherein the third water chamber is fluidly coupled to the second water chamber. The aquarium also includes a water discharge arrangement housed at least partially within the third water chamber, wherein the water discharge arrangement includes a pump and a discharge outlet coupled to the pump such that water within the third water chamber may discharged from the discharge outlet, and further wherein the discharge outlet is selectively rotatable such that water may be discharged either a) into one of the first water chamber or the third water chamber, or b) out of the aquarium.

Provided is an ultrafine bubble generation device for aquaculture or wastewater treatment with which it is possible to efficiently cause ultrafine bubbles to be dissolved or to coexist, and to increase the concentration of a gas in the liquid.
