[Action]

 In the aquarium for transporting live fish of the present invention, the wall material constituting the aquarium main body has a three-layer structure in which the inner and outer layers are made of FRP material and the lightweight heat insulating material is sandwiched as an intermediate layer. Therefore, it is lightweight as a whole, yet has sufficient strength, and has an excellent heat retaining ability that almost prevents the transfer of outside air heat to the water in the water tank by disposing the heat insulating material as the intermediate layer. become. This allows live fish to be transported while maintaining a water temperature that is lower than the optimum temperature for inhabiting live fish, which can suppress fish metabolism and increase the amount of dissolved oxygen in water without weakening live fish. Can be transported.

Further, in the present invention, the water tank body is provided with a water intake port, and the water taken in from the water tank body is discharged from the water discharge port to generate a circulation in the water tank. This prevents weakening of live fish and enhances the filtration efficiency of fish dung and dust in water. Furthermore, the amount of dissolved oxygen in water can be increased by adopting a bubble pump as a means for feeding water from the intake port to the discharge port.

In addition, by disposing a part of the heat insulating material which is the intermediate layer in the wall surface of the water tank main body from the water intake to the water discharge port, the water tank can be made compact and at the same time It is also possible to ensure heat insulation.

According to the present invention, it is possible to further facilitate the maintenance of the water temperature by providing the water temperature adjusting means. In that case, the water temperature can be effectively maintained by arranging the water temperature control means on the water channel that sends water from the water outlet to the water outlet, which is effective when the fishermen and producers are remote islands. Moreover, since the water tank body is excellent in heat retention, the output of the water temperature adjusting means may be small.

In addition, a bubble generation part connected to a blower of a bubble pump is provided for supplementing dissolved oxygen into the water in the water tank, and by making it a porous body, bubbles to be ejected are minute. In addition, it is possible to prevent the fish dung and the like from floating in the water in the aquarium by controlling the ascending speed of bubbles while sufficiently mixing with water, and to prevent the filtration efficiency from decreasing.

In some embodiments of the present invention, the blower of the bubble pump is provided with a check means so that the water in the water tank does not flow backward, so that safety measures are taken against accidents such as the blower being stopped during transportation.

Further, by forming the fork insertion groove of the forklift on the outer bottom surface of the water tank body, it is possible to improve convenience when entrusting transportation to a shipping company such as a ship or vehicle.
