Description

Description Transport method and transport container for aquatic organisms

TECHNICAL FIELD The present invention relates to a method and a container for transporting aquatic organisms for transporting live seafood such as live fish in a container containing water. Background art

The most common way to transport live fish and shellfish is by using a vehicle equipped with an aquarium called a live fish cart. In this method, the tank is filled with as much water as possible to avoid stress on the fish and shellfish being transported, and the fish and shellfish are released and transported in this tank. Therefore, this transport method naturally limits the amount of fish and shellfish that can be transported.

When transporting a large amount of water by vehicle in a large tank, it is indispensable that the vehicle shakes the water in the tank. For this reason, it is feared that this shaking will affect fish and shellfish. In particular, when water is transmitted by the vehicle's sway or vibration, the sway or vibration diverges to the vibration or agitation of the water itself, and the sway in the water is much larger than the vehicle's sway. The impact on the environment will be greater.

According to an experiment, when a drug called apomorphine citrate, which causes humans to feel vomiting, is diluted and injected into common fish such as horse mackerel and bream, it immediately vomits the swallowed food. I know that. On the other hand, in the live fish transport business, where live fish trucks are used for transportation, the vomit of some live fish causes vomiting in a chain to other live fish, further contaminating the water. It is known that death may occur in a short period of time due to this. In other words, as a result of the shaking of the vehicle shaking the water in the aquarium, there is a danger that the fish will get sick and vomited in the same way as humans, and in the worst case they will lose all the live fish.

Therefore, as a countermeasure, feed should be stopped about 3 days before shipment of farmed fish so that live fish can completely digest the feed. However, even if food is stopped, the food may not be completely digested depending on the conditions.Therefore, a test run is performed for a short time at the time of shipment, the state of the water is checked, and if any vomiting is seen, The water is changed immediately. This is because it is better to delay transportation if it is alive than to leave the entire live fish in the tank abandoned.

Therefore, in order to transport live fish to the consumer base with live fish transported by a conventional live fish transport vehicle equipped with an aquarium, it is necessary to be able to stop feeding, and vomiting may still occur. In such a case, there is a risk that the water must be replaced with awareness of the delay in transportation. Furthermore, even if the bait is effective and the transport is successful, the live fish that have not eaten the food for several days before reaching the consumer base can not be said to be healthy and truly lively It's hard to say fish.

In addition, some natural fish and shellfish other than aquaculture cannot be stopped, so it is difficult to transport many fish species with live fish trucks. By the way, the present applicant has indicated “the method of preserving underwater animals” by PCTZJP9805834. In this method, animals such as fish are controlled in part of their motor function so that they do not move when they are alive, so that they can be stored in containers such as Styrofoam and used for relatively long transportation. This is a revolutionary technology that can do this. However, the present inventor has discussed the above-mentioned car sickness. He realized that this storage method alone was not sufficient to cope with the problem, and as a result of earnest research, led to the present invention.

The present invention prevents seafood from getting sick due to shaking or vibration of a vehicle when transporting seafood in a container filled with water. It is intended to provide a method or container for transporting aquatic organisms that will not weaken or die. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is an exploded perspective view showing an example of a container used in the preservation method of the present invention, FIG. 2 is a perspective view of the inner lid viewed from a bottom direction, and FIG. 3 is a live container in a transport container. FIG. 4 is a schematic side sectional view showing a housed state, and FIG. 4 is an exploded perspective view of the transport container of the second embodiment. BEST MODE FOR CARRYING OUT THE INVENTION

The present inventor has considered that in order to prevent fish and shellfish from getting drunk due to vibration during transportation, it is important to keep the water containing the fish and shellfish from shaking. However, it is not easy to keep a large amount of water in a large aquarium such as a live fish car from shaking. Therefore, the present inventor has paid attention to the fact that fish can be stored in a small container by using the above-mentioned “method of preserving underwater animals” proposed by himself. Limiting water sway is relatively easy because small containers have less water.

First, instead of filling the inside of the container with water for transportation, instead of filling the inside of the container, leave a small space at the top of the container, and place the plate-shaped inner lid that floats on the water surface almost covering the water surface. And press it against the surface of the water with some force This ensures that the inner lid keeps close contact with the water surface and prevents the position of the lid from moving following the sway of the water surface.

As a result, even if the vehicle is being vibrated or shaken during transportation, the water under the inner lid does not diverge due to the vibration or shake, and the water does not shake greatly or is agitated.

At first glance, it seems to be sufficient if the water is sealed, but transportation requires air supply as an air supply, and the excess air is released, and water leaks due to shaking and vibration. Can't be prevented by filling the container with water. In this regard, in the transport of the present invention, the excess air from the air escape escapes above the inner lid, and the water that overflows due to vibration etc. once overflows to the upper surface of the inner lid, but returns to the lower part of the inner lid again. Never spill outside.

In addition, the air supply device for the air conditioner is located on the inner lid, and by arranging a cooling agent there, it is effective for cooling the temperature of the water supplied to the water. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Example 1

As shown in Fig. 1, the transport container 2 is composed of a box 21 made of a highly heat-insulating material such as Styrofoam, and a lid 22 that covers this upper part. Add about half of 20 and float the inner lid 1 large enough to cover the water surface almost completely. The inner lid 1 is made of styrene foam having a large buoyancy, like the box 21 and the like. A holding wall 11 is erected on the upper surface of the inner lid 1, gaps 12 are formed at four corners thereof, and a plate 13 for holding an air-ratio pump is formed at the center of the upper surface. . Hold down The wall 11 is erected at a uniform height slightly inside the outer periphery of the inner lid 1. Therefore, the amount of water 20 to be put into the box 21 is the depth of the box 21 minus the thickness of the inner lid 1 and the height of the holding wall 1 1, and the amount of water is added. By closing the box 21, the bottom surface of the inner lid 1 is pressed against the water surface. Since the inner lid 1 itself has a large buoyancy, a force is generated against the pressing against the water surface. Therefore, while holding down the water surface and trying to keep the same position while the water surface is going to sway, the water surface changes very little.

As shown in FIG. 2, a lattice-like groove 14 is formed on the bottom surface of the inner lid 1 at a depth that does not impair the strength of the lid 1.

As shown in FIG. 3, an air supply device 4 for the air rate is placed in the plate 13, and the air supply device 4 is a battery-operated waterproof type, and its outlet 41 is an inner lid. It is provided to be located directly below 1. A coolant 5 is inserted between the holding wall 11 and the plate 13.

The air bubbles that have flowed out from the outlet 41 gradually move to the side of the inner lid 1 while staying between the grooves 11 and are eventually discharged to the outside. Therefore, the time spent in water 20 is long, so that the dissolved amount of oxygen increases accordingly. On the other hand, the impurities floating in the water 20 adhere to the air bubbles, and then the air bubbles adhere to the bottom surface of the inner lid 1, so that the impurities separate from the air bubbles and adhere to the inner lid 1, thereby contaminating the water 20. Can be suppressed. Incidentally, it is also possible to form a large number of fine irregularities on this bottom surface, whereby the residence time of bubbles and the adsorption rate of impurities can be increased.

Further, since the air cooled by the cooling agent 5 is supplied to the air radiator, it is more easily dissolved and has an effect of cooling the water 20, so that a synergistic effect of the air rage is obtained. In addition, by shaking on the inner lid 1 Part of the water that overflowed the surface is cooled by touching the coolant 5 through the gap 12 and then returns to below the inner lid 1, effectively cooling the water 20 itself. Will be Transport experiment example

A transport experiment was performed using this transport container. As the live fish 10 stored in this experiment, a live fish that was previously prevented from being violated by the means for controlling the motor function was used.

The treated fish 10 (fish) was transported in two types: a transport container of the present invention, and a conventional transport container (not shown) in which a simple water-filled box was covered with lids and air-rated. The transport was carried out by the transport method and compared. Transportation was carried out for one vehicle for three hours. In addition, the processing of the motor function control described above was performed without stopping the feeding of any fish.

As a result, in the transportation by the container of the present invention, the water in the container was hardly turbid, there was no evidence of vomiting, and the fish were in good condition due to the movement of the gill lid and the like. On the other hand, for those without an inner lid, the water is all turbid and vomiting is expected. Fish in some containers were dead. Example 2

In the first embodiment, the inner lid 1 and the holding wall 11 that is a means for holding the inner lid are integrally formed.However, the present invention is not limited to this. Is also good.

For example, as shown in FIG. 4, the inner lid 1a is formed as a single plate, and a holding box 11a serving as a means for pressing the upper surface thereof is provided detachably.

Cutouts 1 2a are provided on both sides of the inner lid 1a, and the cutouts are Is formed so that the inner lid 1a can move up and down. A concave portion 13a is formed at the approximate center of the upper surface of the inner lid 1a. The concave portion 13a is fitted to the convex portion (not shown) on the bottom surface of the holding box 11a to form the holding box 11a in the lateral direction. I try not to move.

The means for further pressing the inner lid is not limited to the above-mentioned wall-shaped or box-shaped means, but may be, for example, an elastic spherical panel.

Since the present invention is configured as described above, it has the following excellent effects.

(1) It is possible to transport live aquatic organisms under most conditions to the stored fish and shellfish, because the effects of shaking and vibration during transportation are eliminated and there is no vomiting of food due to sickness.

(2) There is no waste because it is possible to prevent annihilation of each breeding that often occurs in the conventional transportation method. Industrial availability

As described above, the transport method and transport container for aquatic organisms according to the present invention can be used for transport of seafood that transports live fish and the like in a living state.
