Description

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for transporting / preserving live bait for fishing, a method for producing artificial pseudo mud sand used for transporting / preserving live bait for fishing, and a container for storing live bait.
[0002]
[Prior art]
Many fishing baits, such as blue bean used as raw bait for fishing, are imported / exported from Asian countries such as China, South Korea and Vietnam. The loss of live food during overseas transportation is large, and the preservation rate is said to be only about 60%. It is important to preserve the fresh food (including transportation) while keeping it fresh. For this reason, the method of raising the raw food in seawater is adopted, but this method requires time and effort to replace seawater. In addition, the storage period was at most about one week. Conventionally, there has been no appropriate method for easily producing artificial pseudo mud sand that is effective for transporting and / or preserving live bait. In addition, there is a drawback that the raw bait performs an active activity at room temperature, and escapes from a container stored during storage and transportation or at a fishing place.
[0003]
[Problems to be solved by the invention]
The present invention provides a method of transporting and / or preserving raw food that can reduce loss during transportation and storage and maintain freshness for a long period of time. Further, the present invention provides a method for producing artificial pseudo mud sand which is effective for transporting and / or preserving live bait. Another object of the present invention is to provide a container for storing raw food that is not only convenient for transportation and / or storage, but also easy to use at a fishing ground and prevents escape of the raw food.
[0004]
[Means for Solving the Problems]
Means for solving the above problems in the present invention are as follows.
The method of transporting and / or preserving live food according to the present invention is to wash the raw food collected at the habitat with seawater to remove deposits such as mud and sand, and then transport the raw food to a relay point. The mud sand of the habitat is transported to the relay station, and at the relay station, the raw bait is stored in a container together with the artificial mud sand containing the sea beach mud sand and the artificial seawater of the raw bait habitat, and the raw bait stored in the container is stored. Is cooled and transported / preserved to the destination.
The artificial pseudo mud sand containing artificial sea water was formed in a granular form from a mixture of mud sand on the beach in the habitat and plant cellulose fibers. The artificial pseudo mud sand containing artificial sea water may be formed into a granular mixture of mud sand on the beach of the habitat and vegetable cellulose fibers with an additive such as activated carbon.
Before transporting live food to the transit point and / or destination, the live food is discharged out of the body in the seawater, and then the live food is discharged from the seawater to discharge the seawater in the live food body. .
At the relay point, the body material of the raw food is discharged outside the body in artificial seawater adjusted to the same salinity as the seawater in the habitat of the raw food. In addition, paper is immersed in artificial seawater adjusted to the same salinity as the seawater in the habitat of live food to defibrate, and plant cellulose fibers defibrated with artificial seawater and muddy sand on the beach in the habitat The mixture is mixed to form a mixture, an artificial simulated mud containing artificial seawater is formed from the mixture, and raw bait is stored in a container together with the artificial simulated mud at a junction.
Then, the artificial pseudo-mud sand containing the raw bait and the artificial seawater is cooled, and the activity of the raw bait is suppressed and transported / stored. The cooling temperature was in a range of 3 degrees Celsius or more and 9 degrees Celsius or less.
Also, at the relay point, a plurality of storage containers storing live foods are covered with the outer package and transported to the destination, and at the destination, the container taken out of the outer package is cooled and stored, or the user Distribute to
[0005]
In this way, the raw material and the seawater in the body are discharged as much as possible before transporting to the destination. The raw bait collected from the habitat to the relay point cools the bait stored in the container together with artificial artificial mud sand containing artificial seawater, suppresses the activity of the bait, and transports or stores it to the destination. It is effective that artificial artificial mud sand contains artificial seawater composed of plant cellulose fibers obtained by disintegrating paper and mud sand on the beach of the habitat. The storage container for the live food sent to the destination is cooled and stored as it is, or distributed to users.
Therefore, it is possible to collect the live food from the habitat at the relay point, and efficiently transport / store the live food while maintaining the freshness of the live food.
[0006]
Next, the method for producing artificial pseudo-mud sand used in the method for transporting and / or preserving raw bait according to the present invention comprises the steps of immersing paper in artificial seawater and defibrating, and defibrating with the artificial seawater. The method comprises the steps of mixing plant cellulose fibers and mud sand on the beach of the habitat to form a mixture thereof, and forming a granular artificial pseudo-mud sand containing artificial seawater from the mixture. Then, the papers are immersed in artificial seawater adjusted to the same salinity as the seawater in the habitat of the live food, and defibrated.
[0007]
That is, the plant cellulose fibers of papers disintegrated with artificial seawater are rich in water retention, and the use of mud sand on the beach of the habitat reproduces a living environment similar to the beach of the habitat. By appropriately adjusting the mixing ratio of artificial seawater, vegetable cellulose fibers, and beach mud, artificial artificial mud sand suitable for transport / preservation of live bait can be produced.
[0008]
Next, the configuration of the container for storing live food according to the present invention is as follows. In addition, this storage container for live bait can be used in the method of transporting and / or preserving live bait described above.
In a container comprising a top plate and a lid portion provided with a peripheral side portion A, and a bottom plate and a base portion provided with a peripheral side portion B, wherein the lid portion is detachably covered on the base portion, the peripheral side portion B is When the lid is gradually expanded toward the upper end opening of the base and the lid is covered with the base, the peripheral edge of the upper end opening contacts the inner peripheral surface of the lid, while the peripheral side portion A and the peripheral side portion A space is formed between B and B.
Further, in a container comprising a top plate and a lid portion provided with a peripheral side portion A, and a bottom plate and a base portion provided with a peripheral side portion B, wherein the lid portion is detachably covered on the base portion. An edge protruding outward from the peripheral edge of the opening is provided, and when the lid is covered with the base, the protruding edge contacts the inner peripheral surface of the lid, while the peripheral side portion A and the peripheral side portion A is formed between them. Then, the protruding edge portion is elastically brought into contact with the inner peripheral surface of the lid portion, the base portion has flexibility, and a rib is formed on the base portion.
[0009]
That is, since there is no gap between the periphery of the upper end opening and the inner peripheral surface of the lid, even if the activity of the live food is activated at room temperature, the escape of the live food from the container is prevented. In addition, a fingertip is inserted from below into a space between the peripheral side portion A and the peripheral side portion B to securely hold the base portion, and the lid portion and the base portion are easily covered and detachable. It is.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The raw bait has a habit of sinking into the mud and sand on the beach, and the collected bait has mud and sand on the beach. Then, the collected raw food 3 is washed with seawater (natural seawater) to remove extraneous matter such as mud and sand attached to the raw food 3. The raw food 3 after the collection moves actively at normal temperature, and there is a possibility that the attached matter (particularly when it is dried and solidified) may damage the raw food. Wounds not only worsen the viability of live foods, but also make the raw foods inferior, but the removal of deposits eliminates such problems (increases live food viability).
[0010]
The collected live food 3 is stored in seawater (natural seawater) before being transported to the relay point, and the in-body matter is discharged as excrement. They are stored in the seawater at the collection site for about 30 minutes to discharge the body matter, and during that time they do not feed the raw food. The raw food is taken out of the seawater after the discharge of the substance, and then the seawater swallowed by the raw food is discharged outside the body. This is because live foods excrete body materials in seawater, while ingesting large amounts of seawater into the body. Raw food pulled from seawater naturally drains seawater throughout the body. This discharge also takes about 30 minutes. It is effective to discharge both substances in the body and seawater in the body for about 30 minutes.
[0011]
After that, the live bait is transported to the stopover. In this case, usually, live baits are put in a container (not shown) laid with vermiculite or the like and transported to a stopover. It is possible to collect live food not only in one habitat but also in habitats in various places at a stopover. Separately from the live bait, the mud in the habitat of the live bait is collected and transported to the stopover. Mud sand in the habitat is a material for forming artificial pseudo mud sand described later. There is no limitation on the means of transporting live food and mud in the habitat, and transport by airplane or the like. In the relay area, effective means for transporting live food to the destination and subsequent storage can be concentrated.
[0012]
Raw food is stored again in seawater at the stopover. The raw food can be revived by the seawater, and the raw food can maintain its freshness. In this case, the body of the live food is discharged as excrement. No feed is given to the raw feed. After the discharge of the body matter, the raw food is taken out of the seawater to discharge the seawater in the body. In any case, about 30 minutes is effective similarly to the above. Seawater uses artificial seawater with almost the same salinity as the seawater in the habitat of live food. The salinity of seawater is not constant depending on the location and season, but the use of artificial seawater with adjusted salinity makes it easy for fresh food to regain vitality. In addition, by preparing artificial seawater with adjusted salinity according to the habitat, the bait can be transported from the habitats of various places to the transit point for centralized management, and the bait can be efficiently delivered to destinations including overseas. Can be transported. Relay stations can be provided not only along coastal areas but also in inland areas.
The artificial seawater is artificially produced seawater containing at least salt, and may contain other components contained in natural seawater. The “same salinity” does not necessarily have to be completely the same, but may be an average salinity of seawater in a habitat. Usually, if the salinity is in the range of 2 to 4 degrees, this condition is satisfied, and about 2.5 degrees is appropriate.
[0013]
When live food is transported / stored in a state that contains body matter and a large amount of seawater, the live food is likely to be weakened, but before the body is transported to the transit point or destination, the live food is found in the body or in the body. The seawater is drained to a considerable extent, thereby improving the survival rate of live food. In addition, since the accumulation and extermination of excrement of raw food in the container is reduced, it is possible to prevent the living environment of the raw food from deteriorating.
[0014]
While it is desirable to transport / store a large number of live foods in small, lightweight containers, the large number of live foods in the container must be in whole or partial contact. Overcrowding, where live food is entangled in the container, is not suitable as a living environment. In particular, when the temperature rises, the survival rate deteriorates rapidly. In the present invention, the raw bait is stored in a container together with artificial artificial mud at the relay point. The raw bait 3 stored in the container 1 keeps at least partially in contact with the artificial artificial mud sand 2 in granular form, thereby preventing direct whole body contact between the raw baits. When the artificial artificial mud sand 2 is made granular, the contact points and contact opportunities with the raw bait are increased.
[0015]
The artificial pseudo mud sand 2 contains at least artificial seawater. An example of artificial simulated mud sand is granular artificial simulated sand containing artificial seawater, formed from a mixture of vegetable cellulose fibers and beach mud sand. To this, an additive such as activated carbon may be added. The artificial simulated mud sand 2 containing sea beach mud sand (preferably habitat mud sand) and artificial sea water (preferably artificial sea water adjusted to the same salinity as the habitat sea water) reproduces mud sand similar to the habitat. The raw bait 3 has a habit of sinking into mud on the beach and naturally reducing its activity in the mud. The present invention utilizes the habit of the raw bait, and the raw bait stored in the container 1 provided with the artificial pseudo mud 2 competes and sinks between the artificial pseudo mud 2 so as to compete. When the number of raw baits is large, not all of the raw bait can infiltrate into the artificial mud sands 2 and 2, but the raw bait moves the body to get into the artificial pseudo mud sands. And can maintain partial contact. This results in a state of being sunk into the mud and sand of the beach or a state similar thereto, and the live bait naturally weakens its activity. The shape and size of the granular artificial pseudo mud sand are not limited.
[0016]
In addition, the raw bait 3 in the container 1 is cooled together with the artificial artificial mud sand 2 so that the activity of the raw bait can be effectively suppressed. When the cooling temperature is set to substantially the same temperature as the mud and sand in the habitat (usually cooled to about 10 to 13 degrees Celsius), the activity of live food can be naturally reduced. When the cooling temperature is further reduced (usually in a range of 3 degrees Celsius or more and 9 degrees Celsius or less), the live food further weakens its movement as the temperature decreases, and the movement can be suppressed to almost a rest state. However, if the temperature is less than 2 degrees Celsius, the adverse effect on live food is large, which is not preferable. When the cooling is stopped and the temperature becomes normal, the movement of the raw bait becomes active again.
[0017]
Thus, by transporting / preserving the live food while weakening or suppressing the activity of the live food, the freshness of the live food can be maintained and the preservation rate can be increased. There is little or very little excrement, and there is no problem of spoilage of excrement, and a large number of raw foods can be stored in a small container. In the case of artificial simulated mud sand containing activated carbon, the artificial simulated mud sand absorbs the odor generated by raw food. Raw bait does not consume plant cellulose fibers contained in artificial artificial mud sand.
[0018]
For cooling, the container 1 containing the live food is cooled using a livestock cooling agent or the like, or the container 1 is placed in a refrigerator or the like to cool. Cooling may be performed as needed during transportation / storage. At the relay point, the plurality of containers 1 storing the raw food are covered with the exterior body 22 and transported to the destination. At the destination, the trader removes the exterior body 22 or the container 1 taken out from the exterior body 22. Cool and store. The trader can also distribute the container 1 to users. There is no need to subdivide live feed. There is little excretion of raw food, and there is no need to wash the raw food with seawater or store it in seawater at the destination. The user can also cool and store the container 1 temporarily in a refrigerator or the like. At normal temperature such as when used, the raw food 3 in the container 1 returns to its original state. In FIG. 8, the exterior body 8 includes a box portion 9 and an upper lid 12, and a large number of containers 1 are arranged in the box portion 9 divided by a partition portion 11 having a through hole 10. A cooling agent 6 for cooling the container 1 is arranged in a passage 7 between the partition portions 11.
[0019]
The structure of the container 1 for storing raw food is as follows. The container 1 is used for the method of transporting / preserving the raw bait described above, but it is a matter of course that the container 1 can be used independently as a container for storing the raw bait.
In the container 1, which comprises a top plate 15 and a lid portion 5 provided with a peripheral side portion A, and a bottom plate 16 and a base portion 25 provided with a peripheral side portion B, wherein the lid portion 5 is detachably covered by the base portion 25, The side portion B is gradually expanded to the upper end opening 26 of the base portion, and when the lid portion 5 is covered with the base portion 25, the peripheral edge of the upper end opening contacts the inner peripheral surface 27 of the lid portion 5 while the peripheral side portion A A space 20 is formed between the side 20 and the side B. That is, the degree of opening of the opening 26 of the base increases upward, and the peripheral side portion B is inclined from below toward the upper end opening 26 as shown in a sectional view (FIG. 7). Further, an edge 21 protruding outward from the periphery of the opening 26 is provided, and when the lid 5 is covered with the base 25, the protruding edge 21 is brought into contact with the inner peripheral surface 27 of the lid (see FIG. 3). This abutment does not create an unnecessary gap between the peripheral edge of the opening 26 and the inner peripheral surface 27 of the lid, and thus prevents the raw food 3 from escaping from the container 1 even when the activity of the raw food is activated at room temperature. I do.
[0020]
When the protruding edge portion 21 is elastically brought into contact with the inner peripheral surface 27 of the lid by slightly pushing it into the inner peripheral surface 27, not only is there no gap in the contact surface, but also escape of live food can be effectively prevented. . In addition, the lid can be stably covered on the base. Since the outer periphery 17 of the protruding edge 21 is inverted downward, the lid 5 can be easily covered and removed. However, such projecting edges need not necessarily be provided (not shown). The base 25 is formed of a flexible synthetic resin or the like, has the reinforcing ribs 13, and the lid 5 is formed of a breathable material such as cardboard. In the base 25 formed of a non-permeable material such as a synthetic resin, artificial seawater contained in artificial artificial mud does not leak to the outside. Further, since the lid 5 is formed of a breathable material, it is convenient for breathing the raw bait 3 stored in the container 1.
[0021]
The projecting edge portion 21 as described above may be provided, and the peripheral side portion B may be formed vertically so that the space 20 is formed between the peripheral side portion A and the peripheral side portion B (see FIG. 4). In any case, the fingertip of one hand is inserted into the space 20 and the lid 5 is covered and removed while holding the lid 5 with the fingertip of the other hand. Since the base portion 25 is inserted and held, the lid 5 can be easily covered and removed.
[0022]
Also, while holding the base 25 with the two fingers inserted into the space 20, the opposed portions of the peripheral side portion B are slightly pressed inward toward each other to bend the base portion 25 made of a flexible material. Are deformed and the lid 5 can be easily removed. In this case, since the reinforcing ribs 13 are provided, the base 5 is not greatly deformed. When the pressing is released, the base 25 is easily restored to its original shape by the restoring force of the reinforcing ribs 13. Further, the protruding edge portion 21 reinforces the strength and rigidity of the periphery of the opening, prevents damage to the periphery of the opening, and is effective in restoring the original shape of the opening.
[0023]
Next, a method for producing artificial simulated mud used for transport and storage of raw bait, particularly artificial simulated mud made of a mixture of plant cellulose fiber and beach mud is as follows. That is, a step of immersing papers in artificial seawater and defibrating, a step of forming a mixture of plant cellulose fibers defibrated with artificial seawater and muddy sand of a habitat of the beach, and a step of converting artificial seawater from the mixture. And forming a granular artificial pseudo-sludge.
[0024]
First, in the step of immersing paper in artificial seawater and defibrating, the papers are put into a melting tank containing artificial seawater. Papers swollen with artificial seawater are defibrated into vegetable cellulose fibers. Papers may be stirred in artificial seawater to ensure defibration. The paper is preferably one that is easily defibrated, such as toilet paper, but is not particularly limited. It is also desirable to disintegrate with artificial seawater adjusted to the same salinity as the seawater in the habitat of the live food.
[0025]
Next, in the step of mixing the vegetable cellulose fiber and the mud sand, and in the step of forming the mixture, the mud sand of the beach in the habitat is added and mixed with the plant cellulose fiber defibrated with artificial seawater. Mix well so that both materials are almost uniformly mixed. If artificial seawater is adjusted to the same salinity as the seawater of the habitat, and if the mud on the beach is from the habitat, artificial artificial mud is similar to the mud in the habitat and is effective for transporting / preserving live food. . By adjusting the blending ratio of the vegetable cellulose fiber and the mud on the beach of the habitat, the amount of the vegetable cellulose fiber can be increased to provide a lightweight artificial pseudo-mud with rich water retention (amount of artificial seawater). Also, artificial pseudo mud sand close to natural mud sand can be obtained by increasing the amount of mud sand on the beach. Alternatively, the blending ratio between the vegetable cellulose fiber and the mud on the beach of the habitat is almost the same so that the characteristics of both materials are utilized in a well-balanced manner.
That is, a method for producing artificial pseudo mud sand mainly composed of vegetable cellulose fiber, and a method for producing artificial pseudo mud sand mainly composed of beach mud sand. This is a method for producing artificial pseudo mud sand.
[0026]
In the step of forming the mixture, other additives such as activated carbon may be mixed with the vegetable cellulose fibers defibrated with artificial seawater and the mud sand on the beach of the habitat to add the properties of the additive. In the case of activated charcoal, artificial pseudo mud sand having deodorizing action is formed. Activated carbon is preferably mixed in the form of fine particles or powder.
[0027]
Next, in a step of forming artificial artificial mud sand containing artificial seawater from the mixture, the mixture is granulated. Although its size and shape are arbitrary, it is usually about 2 mm to 15 mm. The amount of artificial seawater contained in the mixture is appropriately adjusted in consideration of the transportation / preservation period and the like.
[0028]
【The invention's effect】
According to the method for transporting and / or preserving live food according to the present invention, loss during transportation and storage can be reduced, and freshness can be maintained for a long period of time. Alternatively, there is provided a method for producing artificial pseudo mud sand that is effective for the transportation and storage thereof. Furthermore, it is not only convenient for transportation and preservation, but also easy to use at a fishing place, and becomes a storage container for raw bait that prevents escape of raw bait. Further, since the raw food can be stored fresh for a long period of time, a stable supply of the raw food can be achieved. It is also useful when importing raw bait for fishing from abroad, and also helps maintain raw bait resources.
