In order to supplement the dissolved oxygen in the fish culture water, surface aeration method, aeration method, sparger method, cascade method, ejector method and the like are used. These methods simply release or entrain air or oxygen in water, and bubbles in water have a macro shape, and the rate of being utilized as dissolved oxygen is extremely low, and also due to impact due to macro bubble collision. Moreover, especially fry suffered fractures and other physical damages, and in some cases, death. In addition, the surplus of food accumulated on the bottom of the water and the excrement of fish are easily decomposed, which leads to the production of toxic substances and is often fatally injured chemically.

ことを防止し、腐敗は生じない。[Operation] A part of the aquaculture water or other water is sucked by the pressure water supply pump to pressurize it to 3 to 6 kgf / cm 2 , and the air or oxygen supplied to the suction side of the pressure water supply pump is dissolved under pressure. Dissolved oxygen is given to the water, and the pressurized dissolved water is jetted to the bottom of the fish culture area to disperse the pressurized water and simultaneously reduce the pressure to simultaneously release excess air or oxygen into the water. The released air or oxygen becomes fine bubbles of micron order and is dispersed in water, and the specific surface area of the bubbles is large, so that oxygen is dissolved well in the aquaculture area, and the impact on fry does not occur. It is attached to excess food and fish excrement to reduce the apparent specific gravity and prevent it from staying at the bottom of the water, so that spoilage does not occur.

A pressurized water pump such as a plunger pump that supplies water under a certain pressure, the suction end of which opens into the water in the water tank 3 through the strainer 2, while the discharge end of which is through the injection nozzle 4 at the bottom of the water tank 3. The water supply pump 1 sucks in a part of the water in the water tank 3, pressurizes it, and jets it again from the injection nozzle 4 to the bottom of the water tank 3. Injection nozzle 4
Is a type that can disperse and discharge pressurized water in a wide range and sprays in one direction or in multiple directions. Further, the suction side of the pressurized water pump 1 is connected to an air pump 5 for supplying air or an outlet of an oxygen cylinder 6 via a control valve 7, and the negative pressure on the suction side of the pressurized water pump 1 and the air pump 5 or Due to the discharge pressure of the oxygen cylinder 6, it is mixed in the water sucked into the pressure water pump 1, and while passing through the pressure water pump 1, the oxygen in the air or the oxygen cylinder is pressure-dissolved and injected from the injection nozzle 4. When this is done, the pressure is reduced and the excess is released all at once, forming fine bubbles, and the oxygen in the water in the water tank 3 is efficiently dissolved. Since the released bubbles are minute, they do not damage the fish. In addition, the residual food on the bottom of the tank adheres to the fine bubbles and rises and does not stay. FIG. 2 shows another embodiment of the present invention, in which the pressurized water supply pump 1 sucks in the water inside or outside the net 8 surrounding the fish farming water, and the air or oxygen cylinder 6 from the air pump 5 is sucked.
Oxygen from is dissolved under pressure, released to the bottom of various fish culture areas, and decompressed to generate fine bubbles and give dissolved oxygen.
