Abstract

PURPOSE:To obtain a container device of live fish capable of maintaining multiplication of NH3 decomposing bacteria in filter tank by equipping a sea water filter tank in a live fish tank set in a container, arranging a filter material laid in the filter tank in a filter material cartridge to detachably constitute the filter material against the filter tank. CONSTITUTION:In a container device of live fish having the above-mentioned constitution, a filter material cartridge 2 and a pH adjusting cartridge 50 can be taken out from a wool mat 4 and washed. Consequently, dusts and discharge of live fish trapped by physical filtration can be simply separated. A porous plastic filter material 5 arranged in the cartridge 2 can be partially replaced and when NH3 decomposing bacteria are weakened, the filter material can be simply exchanged for a filter material 5 having bacteria in a separately cultured and multiplied state. Consequently, activity of NH3 decomposing bacteria in the filter tank F can be continuously maintained and further sea water in the live fish tank can be always kept clean.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a live fish container device that is placed on a container truck and transports live fish to a far corner.

(Example) Prior Art The technology related to containers for transporting live fish has been known for some time.

For example, there is a technique described in Japanese Utility Model Application Publication No. 63-53263.

However, although a filtration tank is provided in the conventional technology, it is not clear whether biological filtration by ammonia-degrading bacteria is performed in the filtration tank.

(c) Problems to be Solved by the Invention The present invention solves the problem that the seawater in a live fish tank becomes polluted due to the ammonia excreted by live fish. This relates to a structure that decomposes ammonia and returns it to clean seawater.

When transporting live fish in containers, it is necessary to purify the seawater in the live fish tank. Air is also sent to the ammonia-decomposing bacteria in the filtration tank, and a water flow is also generated in the filtration tank, which improves the overall quality of the fish tank. It is natural to ensure that seawater is filtered, but after transporting live fish,
Even after the seawater in the live fish tank has been drained, the seawater in the filter tank must maintain the vitality of the ammonia-degrading bacteria and continue to maintain its decomposing power.

If the water in the filtration tank is drained after transportation and a porous plastic filter material is inserted, the ammonia-decomposing bacteria will die, and even if the water in the filtration tank is not drained, If air is not sent to the seawater or there is no movement of water current, anaerobic bacteria will breed.
The ammonia-degrading bacteria die.

When the ammonia-degrading bacteria die in this way, they are allowed to grow again on the porous plastic filter material.
It takes two to three days to wait before biological filtration becomes possible, and if the fish do not reproduce sufficiently, biological filtration becomes incomplete and the live fish die.

In such a case, the present invention maintains the growth of ammonia-decomposing bacteria in the filtration tank and facilitates the cleaning of other physical filter media.

(2) Means for Solving the Problems The objects of the present invention are as described above. Next, the configuration for achieving the objects will be explained.

A filtration tank is provided to filter seawater in a live fish aquarium provided in a container, and a filtration material provided in the filtration tank is disposed in a filtration material cartridge so that it can be attached to and removed from the filtration tank.

It is filled with porous blast filter material 5.

The porous plastic filter material 5 does not perform tI filtration, but rather performs biological filtration by allowing ammonia-degrading bacteria to grow therein. Therefore, the porous plastic filter material 5 has the role of a breeding bed for ammonia-decomposing bacteria.

The seawater filtered by the wool mass 4 in the filtering material cartridge 2 and the ammonia-decomposing bacteria then passes between the oyster shells and coral shells filled in the PH adjusting material cartridge 50 to acidify the inside of the PH adjusting material 6. When seawater passes through, the pH adjusting material 6 melts and adjusts the pH to a neutral pH of 7 to 7.5.

Further, the filtered seawater that has passed through the pH adjusting material 6 is sucked into the water circulation pump Pi-P2 shown in FIG. 4 through the suction port 60.

Furthermore, a warming heater 7 is placed at the bottom of the filter tank F to raise the seawater temperature to an appropriate temperature for each transported fish when the seawater temperature is very low.
