点がある。
By the way, in the past, the pressure inside the aquarium was maintained at atmospheric pressure before being transported, which meant that the oxygen blown into the water did not dissolve well, and on the other hand, fish in the aquarium suffered from vibrations during transportation. The disadvantage is that it tends to move more violently, which often weakens the fish.
そこで、この発明は上記の欠点を解決し、魚を
弱らせることなく輸送することを技術的課題とし
ている。 Therefore, the technical object of this invention is to solve the above-mentioned drawbacks and to transport fish without weakening them.

According to the above-mentioned transportation, since the pressure at the top of the tank is higher than the atmospheric pressure, it is possible to increase the dissolution rate of the air or oxygen blown into the tank into the water, and the living conditions in the tank can be adjusted to the same level as those in the aquaculture pond. Since the habitat conditions can be approached, the fish can be made to settle down, and as a result, the fish can be transported without weakening them.

より高めるようにする。 The aquarium 1 shown in the embodiment has the above-mentioned configuration, and when using this aquarium 1 to transport raw fish, the aquarium 1
After filling the inside of the aquarium with seawater and placing fish in the aquarium 1, the lid 26 is fully closed, and the surface of the seawater in the aquarium 1 is heated by air or oxygen supplied from the supply pipe 7 into the drainage guide tube 3. The pressure of the air layer formed in the air is raised above atmospheric pressure.

１内を上昇してスリツト１０から水槽１内にも流
れ、水槽１内の圧力が上昇する。 Now, after fully closing the lid 26, turn on the blower 8.
When air or oxygen is supplied from the supply pipe 7 into the drainage guide cylinder 3, this supplied fluid flows through the filter cylinder 1.
1 and flows from the slit 10 into the tank 1, increasing the pressure inside the tank 1.
上記圧力が安全弁５の設定圧力を超えると、そ

上の空気層の圧力を安全弁５の設定圧力に保持す
ることができる。 When the pressure exceeds the set pressure of the safety valve 5, the safety valve 5 opens, so that the pressure of the air layer above the seawater surface in the aquarium 1 can be maintained at the set pressure of the safety valve 5.
水槽１内の海水表面上の空気層の圧力は、その
内側に入れる魚の種類に応じて適宜に決定し、例
えば鯛やはまちの場合は１Kg／cm2ゲージ圧、ふぐ
や鮃の場合は２Kg／cm2ゲージ圧の圧力状態に保持
する。 The pressure of the air layer above the seawater surface in the aquarium 1 is determined appropriately depending on the type of fish to be placed inside.For example, for sea bream and yellowtail, the pressure is 1Kg/cm 2 gauge pressure, and for blowfish and tuna, it is 2Kg/cm2 gauge pressure. Maintain pressure at cm2 gauge pressure.

も魚に落ち付きがあり、輸送中に魚が弱るのを防
止することができる。 By increasing the pressure of the air layer in the aquarium 1 above atmospheric pressure, oxygen can be dissolved in seawater better.
In addition, the pressure of seawater is high throughout, and raw fish are maintained at almost the same pressure as in aquaculture ponds, so even if the seawater is shaken by vibrations during transportation, the fish remain calm during transportation. This can prevent the fish from weakening.

できる。 During transport of fish, the pump 21 is driven to forcefully send the seawater in the drainage guide cylinder 3 to the annular pipe 19, and the seawater is injected into the circulation chamber 18 from the nozzle 22 of the annular pipe 19. A unidirectional swirling flow is generated, and the seawater in the circulation chamber 18 flows into the aquarium 1 through the holes 24 in the top plate 23, so that a unidirectional flow can also be formed in the aquarium 1.

全弁５の開放時に、外部に排出される。 Also, since the water level in the tank 1 increases, the seawater at the top of the tank 1 flows from the slit 10 into the drainage guide tube 3, flows into the filter tube 11 from here, and flows into the filter medium 1.
3, impurities are removed and the filtrate is pumped into the circulation chamber 18. Further, the impurities collected on the filter medium 13 are transported above the drainage guide tube 3 by the supply fluid blown up from the aeration pipe 6, and are discharged to the outside when the safety valve 5 is opened.

As described above, according to the present invention, oxygen or air is supplied into a pressure-resistant sealed water tank containing seawater or the like to raise the pressure of the air layer on the water storage surface above atmospheric pressure,
By transporting raw fish in this condition, oxygen dissolves well in the seawater, making it possible to increase the amount of dissolved oxygen and increasing the pressure of stored water throughout the tank. Therefore, the environment inside the aquarium can be made almost equal to the habitat conditions of an aquaculture pond, and as a result, raw fish can be transported without weakening them.
