Description

Detailed Description of the Invention (Industrial Application Field) The present invention is a method for resuscitating live fish that is in an suspended animation state without freezing it, transporting it at a low temperature, or refrigerating it. ), a method for transporting live fish at a low temperature, a container for low-temperature transport, and a container cooling device for transport.

[Prior Art] Conventionally, it is well known that fresh seafood is packed in crushed ice or saline water and transported in ice or cold storage to prevent it from freezing.
It was not possible to compose the product after transportation. Therefore, for -g,
They simply placed live fish in water and transported it.

In addition, the present inventor previously developed (patent application No. 2-20512
No. 2) The method of transporting live fish using anabiosis and the method of cooling water in containers for transporting anabiosis have a constant cooling rate;
Not compatible with all fish species.

In addition, the method of keeping aquariums containing asphyxiated live fish cold uses cold storage materials, so the temperature cannot be lowered below the temperature at which the water is cooled in the cooling unit, and the temperature only increases as time passes.

[Problem to be solved by the invention]

The present inventor devised a method that allows all live fish caught by a fishing boat to be transported to a port while still alive, and which does not place a heavy burden on the fishing boat. In addition, it is possible to purchase live fish from fisheries cooperatives, fish farms, etc., put it into a state of low-temperature asphyxia, transport it in a low-water volume or anhydrous state at a low temperature, and then reconstitute it to the consumption area and deliver the live fish to consumers. As a result of research into a transportation method that allows live fish to be transported all the way without reloading, this book makes it possible to eliminate the need for large amounts of water for live fish to swim in, transport live fish with a light weight, and make it possible to eat seasonal live fish both in summer and winter. He completed his invention.

[Means for the invention to solve the problem]

The transportation method of the present invention involves circulating purified, oxygen-supplemented, and cooled water to live fish in the water in an insulated aquarium for a container, and cooling them to an appropriate temperature at a cooling rate tailored to the fish species. In some cases, far-infrared rays are irradiated to cool the animal to a state of suspended animation without freezing to death, and then the water is removed, or without being removed, the water is covered with an insulating lid and kept at a low temperature of about 10 to -15°C. The process consists of transporting the live fish in a state of suspended animation, and then reviving the live fish. When doing so, the temperature inside the tank is kept cold using electricity, coolant (dry ice, etc.) or a temperature controller, the cooling time is set, and the appropriate cooling temperature range is automatically maintained.

The container water tank according to the present invention is equipped with far infrared rays on the lower surface,
and an opening removably covered by a heat insulating lid having a coolant storage section, and a top plate having an electric cooling section adjacent to the opening and having a temperature indicator. A sensor is provided on the side wall and a waste water port that can be opened and closed is provided on the bottom wall.A water inlet and a water outlet that can be opened and closed are provided on the top plate of the aquarium. This is a shipping container water tank with a water supply port located at the top of the side wall.

When circulating water, two to more of the above water tanks are used.
There are two types: the series method, in which the water tank on the cooling unit side is placed higher than the other water tank, and the water circulated.In the series method, the water flow between the cooling unit and the water tank is one ring, and in the parallel method, A connecting pipe extends from the cooling unit in an octopus shape and is connected to the water tank.

In addition, the reason why two or more aquariums are used is because the cooling temperature differs depending on the fish species while cooling the water. To stop the circulation, remove the connecting vibrator from the cooling unit, and if the aquarium has water, pump the air into the aquarium and replenish oxygen for cultivation, and if the aquarium does not have water, drain the water in the tank. . The other water tanks are connected to the cooling unit with a communication vibrator and continue to be cooled. Each water tank can be kept cool at a different appropriate temperature.

The cooling unit according to the present invention includes, on the other side of the upper part, a bubble removal chamber through a wall having a bubble passage, an electricity generation chamber, an aeration chamber having an aeration device, and a purification filtration chamber.
- On the blade side, there is a cooling chamber with a water supply inlet and a water return inlet that can be opened and closed at the top of the side wall. is introduced into the aeration room. The cooling water circulation supply device is configured to supply water from the water supply port to the water receiving port of the aquarium after the water has been oxygen-supplemented, purified and filtered, and cooled.

The suspended animation state of live fish during transportation according to the present invention is as follows:
It means that the fish have stopped their activity and become stationary (inactive state) due to the cooling treatment, and it also means the state that occurs when the fish are kept cold at a low temperature of 10 to -15°C and then warmed. In addition, the transportation temperature is set at 10 to -15°C, and the measured temperature after cooling treatment is maintained in the temperature range of 10 to -15°C to transport live fish in rows without being damaged or killed. This is because the fish can be resuscitated after transportation, and can be served as fresh fish to the table.

If the temperature exceeds 10℃, live fish in suspended animation will become violent and be damaged.
It also increases oxygen requirements and shortens survival time. Also, depending on the species of fish, it is possible to take them out of the water, rapidly expose them to cold temperatures of -15 degrees Celsius, freeze them alive, and then revive them when they respond.

The reason why water is removed from the aquarium after the cooling treatment is because it is preferable for transportation by reducing the amount of fruit juice, etc., and the reason why water is not removed is because it makes it possible to transport all live fish, and the water can be simply added. This is because it can be resuscitated by heating.

In the cooling treatment according to the present invention, the water in the aquarium containing live fish can be cooled by any appropriate means, but it is preferable to cool the water by sequentially circulating the cooling water. In the cooling process, it is preferable to irradiate the live fish with far-infrared rays, depending on the species, in order to avoid stress on the live fish and prevent them from freezing.

The cooling rate varies depending on the species of fish and the temperature range, but
Usually 1-b In addition, in resuscitation treatment, in the case of anhydrous shaking, after transportation, water (fresh water or seawater) close to the measured temperature is placed in a tank,
It is preferable to irradiate far infrared rays for heating. In either case, this is to facilitate the resuscitation of live fish in a state of suspended animation.
This is because fish in a state of suspended animation can be made to swim actively.

In the present invention, live fish means almost all seawater or freshwater fish, and in particular, crucian carp, carp, eel, rockfish, rockfish,
Draftfish, sea urchins, spiny lobsters, crabs, etc. are preferred.

In addition, live fish can be cooled by placing them in a mesh cage and stacking them in several tiers, or by placing them in water in an insulated aquarium without placing them in a mesh cage, and after the cooling process, the water can be removed or not removed. They can also be transported at low temperatures with an insulating lid on them, without removing them or placing them in a mesh basket.

Example 2 (land transportation) Live fish transportation container A- having the same structure and the same size
Using the apparatus described in Embodiment 1 in which B is installed in series, the water inlet 8 of the water tank 1 of the container A and the water supply port 15 of the cooling unit C are connected through the water supply pipe 14, and the Water inlet 17 of tank 1 and water inlet 8 of tank 1 in container B

In the tank 1 of Container A, put 100 flounder (live fish) into 6 fish net baskets 20, sequentially starting from the opening 3, and in the tank 1 of Container B, put 30 draft puffers. After storing 6 fish net baskets 20 sequentially from the opening 3 and adjusting the seawater level to a level higher than the upper surface of the uppermost fish net basket, the cooling unit C is turned on, and the circulation pump P and aeration are turned on. The device 22 is operated, and the seawater in the water tank 1 of the container B is sent from the water outlet 9 to the lower part of the aeration chamber 21 through the circulating water pipe 16 for aeration treatment. The seawater flowing down from the air bubble outlet at the upper part of the air bubble removal chamber 23 and supplemented with oxygen is guided by a member 32 from a water outlet located lower than the air bubble outlet, and is purified and filtered. After being sent to the lower part of the chamber 24 and subjected to purification and filtration processing, it is sent to the cooling room 25, where it is cooled and sent to the water tank 1 of the container A through the water supply port 15, the water supply pipe 14, and the member 11. , the water tank 1
Cooling seawater was fed into the water tank 1 of container B from the water supply port 17 of the container B through the water supply pipe 16, and circulated to the containers A and B.

When the draftfish enters an asphyxia state due to this circulation cooling process, the water supply port member 17 and the water intake port member 8 of the water tank 1 of container B are closed, the water supply pipe 16 is removed, and the water in the water tank 1 of container B is drained. The mouth 9 was closed, and the water outlet 9 of the container A was opened to circulate cooling seawater in the container A, thereby continuing to cool the water tank to the container.

Next, after draining the seawater in the water tank 1 of the container B to make it anhydrous, the water tank 1 was powered on and the cooler 4 was activated to start cold storage.

When the flounder in the aquarium 1 of the container A, which has been continuously cooled, reaches a state of suspended animation, the power to the cooling unit C is turned off, aeration, cooling, and water circulation are stopped, and the water supply port 8 and water outlet of the aquarium 1 of the container A are turned off. 9 was closed, the water supply pipe 14 and the water circulation pipe 18 were removed, and the seawater was drained in the same manner as in the aquarium of container B to make it anhydrous, and then the container was kept cold.

After transporting the flounder overland for 10 hours while keeping it cool, +5°C seawater was put into each tank and irradiated with infrared rays.
It was suitable for being revived and eaten as live fish along with draftfish.

Example 3 (Marine transport) The device of Example 2, which does not use the fish net cage 20, is mounted on a squid fishing boat, and each water tank 1 of containers A and B is filled with seawater to carry out aeration, cooling, and circulation. However, when we stocked the captured squid in each tank and gradually started cooling them, the squid became inactive, and compared to the seawater in the tank, we were able to transport a larger amount of squid than usual in an inactive state. Ta. After being warmed up after transport, the squid was resuscitated.

Furthermore, since the amount of seawater in the tank can be reduced and the weight of the container can be made lighter, it has become easier to steer the ship during transportation, and it has become possible to return to port at a faster speed.

[Effects of the Invention] According to the present invention, various problems in which the cooling rate and cooling means differ depending on the season and species of fish, and even depending on the habitat of the same species of fish are solved, and stable and simple transportation is possible. It is possible to replenish oxygen, purify, and circulately supply cooled water to the aquarium, and also to irradiate far infrared rays in the aquarium and variably cool it at a predetermined temperature, allowing live fish to die without stress. It was possible to cool it down to a certain temperature, cover it with a lid, adjust the water tank temperature to any desired temperature, keep it cool, and transport it safely. When resuscitating live fish in their original state, it was possible to easily revive them by irradiating them with far-infrared rays in an aquarium or bathing them in warm water.

The present invention provides a container for live fish and a device for transporting live fish that not only facilitates the transportation and resuscitation of live fish in a state of suspended animation, but also enables an integrated distribution system within a logistics mechanism that can be used as a fish tank or a refrigerator. was obtained.
