微細な空孔ができにくいという問題を有している。However, when the oxygen bubble generating member is made of plastic or a sintered alloy as in the prior art, since the plastic and the sintered alloy have poor wettability with water and seawater, oxygen is not generated. Bubbles adhere to and collect on the surface of the bubble generating member to form coarse bubbles. Also, when glass is used to form pores in the glass by machining, it is possible to form fine pores. It is difficult, and therefore the bubbles that can be formed become rough, and when ceramics are used, the ceramics have few holes (open pores) that contribute to the formation of high-quality oxygen bubbles.
It has a problem that it is difficult to form fine holes.

45 cm wide with three oxygen blowing devices 1 using 9 as the body part 4 of the oxygen bubble generating member 2 and 50 liters of seawater
It was placed in a plastic water tank of × 45 cm and a depth of 60 cm. The dimensions of the oxygen bubble generating member were 11 mmφ × 50 mm. Also, the oxygen pressure is 0.5 kg /
cm 2, flowing oxygen at a flow rate 120 cc, oxygen bubbles are generated is visually or fine and uniform, with the state of the foam to determine whether is good, the measurement of oxygen dissolved amount of seawater in each aquarium did. Furthermore, about 20 kg of sea bream was released into each water tank, and 10 water tanks were transported by a truck for about 24 hours, and the survival rate at that time was measured. The above results are shown in Table 1.
It was shown to.

も９０％以上となり、良好であった。As can be seen from Table 1 above, the average radius of the pores of the carbon material forming the oxygen bubble generating member is 2.0 to.
In the range of 0.6 μm, the A / B value is 0.2
Up to, that is, if A / B ≦ 0.2, the generated oxygen bubbles are fine and uniform, which is good. Therefore, the dissolved amount of oxygen in water is large, and as a result, the survival rate of fish ( %)
Was 90% or more, which was good.

く提供できるようになる。As described above, according to the oxygen blowing apparatus of the present invention, it is possible to efficiently supply the oxygen bubbles to the water in the water tank in a good condition, and thus the oxygen solubility in the water is good. Therefore, a large amount of fish can be used with little water. Therefore, the water tank can be made smaller,
The transportation space for automobiles, airplanes, etc. will be smaller, and it will be possible to transport fish that was not possible before, and the transportation cost per fish will also be reduced, so it will be possible to provide live fish to customers at low prices.
