る。In such a configuration, compressed air sent from the air compressor (7) is supplied to the lower part of both upwelling bodies (4) through the hose (6) or the hose (6) and the branch hose (20). be done. The compressed air supplied to the lower part of both upwelling bodies (4) rises within the upwelling bodies (4). At this time, the pressure inside the upwelling body (4) becomes lower than the external pressure at the lower part, and seawater flows into the upwelling body (4) through the communication port (10). The seawater that has flowed into the upwelling body (4) rises together with the compressed air, and an upwelling flow is generated within the upwelling body (4). Upwelling body (4
The seawater that has risen inside ) is blown out from the communication port (9) at the upper end.

る。When an upwelling flow is generated within the upwelling body (4), a circulation flow of seawater is induced as shown by an arrow (A) in the drawing, and circulates between the seabed and the sea surface. The circulation flow of seawater prevents the accumulation of leftover food on the sea floor and the fish tank (1), and also allows the nutrient-rich seawater in the bottom layer to rise to the sea surface, increasing the number of zooplankton. . In addition, the compressed air sent by the air compressor (7) dissolves in the seawater, thereby eliminating the lack of oxygen in the seawater.

However, it is not limited to this. In addition, in the above, the upwelling body is suspended from a float floating on the sea surface, and
The lower end is fixed to the sinker, allowing it to stand in the water! ! However, the method of arranging the upwelling body while standing in the water can be changed as appropriate. Moreover, although compressed air is sent into the lower part of the upwelling body in the above, the gas to be sent is not limited to compressed air. Furthermore, the structure, number and arrangement of upwelling bodies are
The number and arrangement of hoses and gas supply means are not limited to those in the above embodiments, and can be changed as appropriate.

動物性プランクトンを増加させることができる。Effects of the Invention Since the water circulation device according to the present invention is constructed as described above, if the upwelling body is placed standing in water and gas is sent into the lower part of the upwelling body, an upwelling flow can be generated inside the upwelling body. occurs, and as a result water circulation is induced. Therefore, the circulating flow of water can prevent the accumulation of leftover bait on the seabed or in the cage. In particular, if air or oxygen is used as the gas to be fed, the air or oxygen will dissolve into the water, increasing the amount of oxygen in the water and eliminating the oxygen shortage. In addition, water circulation makes it possible to equalize water temperature and water quality. therefore,! ! Preventing the aging of breeding grounds and maintaining a good living environment for fish and shellfish. Furthermore, if this water circulation device is used in the ocean, it is possible to raise the nutrient-rich seawater from the ocean floor to the sea surface and increase the number of zooplankton.
