Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to sea fishing, river fishing,
The present invention relates to a bait used for collecting fish when fishing in a lake or pond.

[0002]

2. Description of the Related Art In the case of fishing, a sow bait is thrown into a makie basket or thrown directly around a bait to collect fish. As the sow bait, raw or frozen seafood such as shrimp and small fish is used.

[0003]

However, when thrown into the water, the sow bait receives the resistance of water until it reaches the target shelf, so that a large amount of the bait is dispersed, so that the target bait can be spread sufficiently on the target shelf. Is difficult. Therefore, it was necessary to throw in a large amount of bait in order to sufficiently spread the bait on the target shelf.

[0004] In addition, since seafood has a peculiar odor and stickiness, handling of bait is accompanied by discomfort, and raw or frozen seafood has poor preservability and should be left as it is at a fishing place. It will rot immediately. Therefore, after fishing, it is necessary to take the remaining bait back as a cleanup, but due to the above circumstances, it is often discarded at the fishing ground. This has spurred the accumulation of a large amount of sowing bait on seabeds and other shelves, which has led to serious problems of destroying the environment and changing its ecosystem. Particularly in fishing parks and large breakwaters, many holidaymakers gather on holidays, so that many tons of bait may be unduly dumped on that day alone.

[0005] Further, to prepare a sow bait, many tools are required, such as a bucket for storing fish and shellfish as a bait, a knife for crushing the seafood, gloves, and a soap for washing dirty hands. Therefore, since a fishing rod, a device, a cooler box, clothing, and the like are required in addition, it is difficult to enjoy fishing easily because of an increase in luggage.

[0006] It is an object of the present invention to provide a sow bait used for fishing that can be efficiently put into a target shelf, and that it can be easily stored and easily handled.

[0007]

The technical means taken to solve the above-mentioned problems are as follows.

[0008] The whole is composed of a porous dry solid,
The dried solid material is formed by drying a mixture containing a fish paste and a water-absorbing binder having a specific gravity greater than that of seawater or freshwater. The technical means operates as follows.

[0009] When the dried solid material constituting the present sowing bait is put into water, the dried product of the fish and shellfish paste is inherently sedimentable, and the binder has a specific gravity greater than that of seawater or freshwater. The dried solids sink into the water. In addition, since the dry solid is porous, water enters through the myriad of holes on the surface and gradually absorbs and disperses the water. Then, the dispersed particles are dispersed around. Therefore, even if the sow bait is thrown into water, it does not disperse immediately, so that the sow bait can efficiently reach the target shelf.

[0010] Also, since the present bait is a dry solid,
Unlike conventional sowing bait using raw and frozen bait, it can be handled easily without soiling the hands, and there is no fear of bad smell or decay.
Therefore, what is left after the fishing is taken back and can be used for the next fishing.

In the above technical means, it is preferable that “the dry solid material has a porous space volume ratio of 60% to 80% of the whole.
%, The remaining 20% to 40% is the mixture component from which water has been removed, so that the mixture component having a fish collecting effect is concentrated to 20% to 40%. Therefore, on the target shelf, a high fish collecting effect can be exhibited by dispersing the mixture in which the smell and taste of the seafood extract are also concentrated.

Further, in the above technical means, according to "the dried solid is a freeze-dried product of the mixture", the odor, color, taste, etc. of the fish and shellfish contained in the mixture are not impaired. Moreover, it becomes a porous dry solid matter from which only water is removed without denaturing the protein component. Therefore, when it is returned to water, it is well dispersed and restored to the original mixture in which the odor, color, taste, etc. have hardly changed, so that a high fish collecting effect can be exerted on the target shelf.

[0013]

According to the present invention, the following effects can be obtained. 1. Since it does not disperse immediately after being put into water, it is possible to efficiently reach the target shelf and reduce the amount of use. 2. By making it a dry solid, there is no fear of bad smell or decay,
Good preservability. Therefore, the remaining bait can be brought back and used for the next fishing, so that it will not be discarded at the fishing ground, thereby preventing the environmental destruction due to the accumulation of the bait and not changing its ecosystem. 3. Since the present bait is composed of a dried solid containing a dried seafood paste as a component, the bait can be easily handled as it is without using a conventional tool for preparing the bait. Can be. 4. In the case where the porous solid volume ratio occupies 60% to 80% of the whole as a dry solid, the mixture component having the effect of collecting fish from which water has been removed contains 20% to 40% of the whole.
Since it is concentrated in water, it can exhibit a high fish collecting effect. 5. Furthermore, if the dried solid is freeze-dried, the original mixture, which has almost no change in odor, color, taste, etc., is restored on the target shelf, so that a higher fish collecting effect can be exhibited.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the sowing bait according to the present embodiment is composed of a porous dry solid material 10 having a myriad of holes 11 as a whole. And
The dried solid 10 is formed of a mixture 6 including a fish paste 4 and a water-absorbing binder 5 (FIG. 2).
reference).

The dry solid material 10 is formed in a rectangular parallelepiped block shape having a size that can be inserted into the makie basket 2.
Its size is about 20 mm × 20 mm × 40 mm, but it can be changed as appropriate as long as it can fit in the Makie basket 2. Moreover, the diameter of the holes 11 which are innumerable throughout is about 0.1 μm to 3 mm. This pore size is 0.1
If it is less than μm, the penetration of water into the dried solid material 10 in water may be poor, resulting in poor dispersibility as a bait. On the other hand, if it exceeds 3 mm, the shape retention of the dry solid material 10 may be poor, resulting in poor shape. There is a risk of collapse. When the dried solid material 10 is formed by freeze-drying (vacuum freeze-drying method), an elongated needle-like hole 11 having a hole diameter of about 0.1 μm to 100 μm is obtained.

As the fish paste 4, for example,
Shrimps such as prawns, crabs, shellfish such as oysters and clams,
Squid, squid, other small fish, etc. are finely pulverized and processed into a paste. These seafood extracts exert the effect of attracting fish and collecting fish around the bait. This seafood paste 4
Is used in an amount of 40 to 80 parts by weight based on 100 parts by weight of the mixture 6. If the amount is less than 40 parts by weight, the fish-collecting effect may not be sufficiently exhibited, while if the amount is more than 80 parts by weight, the shape retention of the dry solid substance 10 may be deteriorated and the dried solid substance 10 may lose its shape.

As the water-absorbing binder 5, for example,
Pastes and dry powders such as soybean meal such as okara, wheat, bread crumbs, sake lees, cereal meal, and diatomaceous earth are used. The binder 5 is not particularly limited as long as it is a material having water absorbability and settling in seawater or freshwater. This binder 5
The mixture 6 is used in an amount of 20 to 60 parts by weight with respect to 100 parts by weight. That is, if the amount is less than 20 parts by weight, the shape retention of the dry solid matter 10 may be deteriorated and the shape may be lost, while if it exceeds 60 parts by weight, the ratio of the seafood paste 4 is reduced and the effect of collecting fish is reduced. There is a possibility that it will not be able to fully demonstrate.

The mixture 6 is appropriately added with an attraction component for attracting fish and a preservative. The amount added is 20 parts by weight or less based on 100 parts by weight of the mixture 6. Examples of the attractant include krill concentrated extract, prawn extract, trolocob,
Squid oil and other amino acids such as glutamic acid, inosinic acid, taurine, proline, lysine, tryptophan, and alanine. As the preservative,
For example, garlic and the like can be mentioned.

Next, a method for producing a sow bait comprising the dried solid matter 10 will be described. FIG. 2 is a schematic diagram showing a process of producing the sow bait.

First, the fish and shellfish such as shrimp and crab are pulverized by the mixer 3 (FIG. 2A). When the fish and shellfish become substantially paste-like, the water-soluble binder 5 such as okara is put into the mixer 3 (FIG. 2B). At this time, the attraction component, the preservative, and the like may be appropriately added. And
By stirring well, a mixture 6 containing the fish paste 4 and the water-soluble binder 5 is obtained. Then, seafood paste 4
The seafood extract therein impregnates the water-absorbing binder 5. Therefore, this mixture 6 contains the fish and shellfish extract. Preferably, the water content of the mixture 6 is adjusted to 60% to 80%. However, raw or frozen seafood is 7
About 0% to 90% is composed of moisture, and edible okara is 50% to 80% as the water-soluble binder 5.
Containing a certain amount of water, the seafood paste 4
When 80 parts by weight and the water-soluble binder 5 are mixed at a ratio of 20 to 60 parts by weight, the water content of the mixture 6 becomes 60% to 80%.
Range. However, when a water-soluble binder such as a dry powder that contains almost no water is used, the water content of the mixture 6 may be adjusted by appropriately adding water.

Next, a container 7 in which a plurality of rectangular parallelepiped portions are formed by the partition plate 8 is prepared, and the mixture 6 is poured into the container 7 until the partition plate 8 is filled (FIG. 2C). As a guide at this time, the mixture 6 poured above the partition plate 8 is preferably about half or less of the height of the partition plate 8. That is, in this way, the partition plate 8 forms a groove and is finally obtained as an aggregate of blocks like a curry roux. Then, the mixture 6 poured above the partition plate 8
Is set to about half or less of the height of the partition plate 8 in order to make the depth of the groove such that one block 12 can be easily broken by hand. If the partition plate 8 and the container 7 are prepared such that the height of the partition plate 8 is about two-thirds or more of the depth of the container 7, the mixture 6 is thoroughly poured into the container 7. If it puts it, it will be said relation.

After freezing the water in the mixture 6, the mixture 6 is put into a vacuum freeze-drying apparatus 9 and dried by freeze-drying (vacuum freeze-drying) (FIG. 2 (d)).
In order to freeze the moisture of the mixture 6, the container 7 containing the mixture 6 may be left in an environment of 0 ° C. or lower (for example, in a freezer). Further, as the freeze-drying conditions,
The degree of vacuum or decompression is 0.60 Torr to 0.05 Torr
The drying temperature is 10 ° C. to 40 ° C., and the drying time is about 9 hours to 30 hours.

By the freeze drying, the frozen water in the mixture 6 in the container 7 sublimates without liquefaction.
That is, only water is removed from the mixture 6,
A porous dry solid 10 having a volume almost equal to that of the mixture 6 is obtained.

Then, the dried solid material 10 is removed from the container 7.
As shown in FIG. 3, the dried solid 1 having a shape similar to a curry roux in which a plurality of rectangular parallelepiped blocks 12 are continuously connected on one side is obtained. When this is divided for each block 12, the dried solid 10 shown in FIG. 1 is obtained.

In the freeze-drying, the temperature is set at 10 ° C.
Although the temperature is kept at 40 ° C., in this temperature range, the odor, color, taste, etc. of the fish and shellfish in the mixture 6 are not changed, and the protein is not denatured. Therefore, the obtained dried solid substance 10 can be used by throwing it into water as a sow bait, and when it absorbs moisture, it is restored to the original mixture 6 with the same odor, color and taste.

In addition, since the water is distributed evenly throughout the mixture 6, the freeze-drying provides the whole porous dry solid 10 which is almost the same as the volume of the mixture 6. That is, it does not become as hard as dried fish. The resulting porous dry solid 10
When water is introduced into water, water enters through the myriad of porous holes 11 and absorbs water little by little. Therefore, the sowing bait can reach the target shelf efficiently, and
It can be dispersed well on the target shelf.

Also, the obtained porous dry solid 10
Consists of a plurality of rectangular parallelepiped blocks 1 like curry roux
2 is a continuous form on one side, so that the angler can easily break the blocks 12 one by one when using the bait. In addition, if the partition plate 8 is arranged so that the size of the block 12 can fit in the makie basket 2, the block 12 can be used as it is in the makie basket 2 as it is, thus improving the convenience in use. Moreover, since a large number of the blocks 12 can be obtained by one production, the production efficiency of the sowing bait is very good.

Further, the water content of the mixture 6 is reduced to 60%.
When it is adjusted to 80%, only the moisture is removed by freeze drying, so that the space volume ratio is 60 to 80% of the whole.
% Of the porous dry solid 10 is obtained. In other words, the obtained dry solid matter 10 exhibits a higher fish-collecting effect on the target shelf since the six components of the mixture having a fish-collecting effect are concentrated to 20 to 40% of the whole.

As described above, the following effects are obtained by the sowing bait according to the present embodiment. 1. Since it does not disperse immediately after being put into water, it is possible to efficiently reach the target shelf and reduce the amount of use. 2. By using the dry solid material 10, there is no fear of bad smell or decay, and the storage stability is good. Therefore, since the remaining bait can be brought back and used for the next fishing, it will not be discarded at the fishing ground, thereby preventing the environmental destruction due to the accumulation of the bait and changing its ecosystem. 3. The present sowing bait is composed of a dried solid material 10 composed of dried fish paste 4 as a component, so that it can be used as it is, and the dry solid material can be used without using a conventional tool for preparing sowing food. 10 Can be easily handled as it is. 4. In addition, since the porous space volume ratio of the dried solid material 10 occupies 60% to 80% of the whole, the six components of the mixture having the effect of collecting fish from which water has been removed are concentrated to 20% to 40% of the whole. Therefore, it can exhibit a high fish collecting effect. 5. Furthermore, by making the dry solid a freeze-dried product, the target mixture is restored to the original mixture 6 with almost no change in odor, color, taste, etc., so that a higher fish collecting effect can be exhibited. .

In the above-described embodiment, a plurality of rectangular parallelepiped blocks 12 are connected on one side like a curry roux as a form of the dried solid 1 after production. It may be manufactured as follows. Also,
The shape of the dried solid material 10 is not limited to a rectangular parallelepiped, but may be a cylindrical block 12 that conforms to the shape of the makie basket 2.

Next, a specific example will be described. (1) Production of Dry Solids 67 g of shrimp and 10 g of oysters were pulverized with a mixer to produce a fish paste. Then, 15 g of dried okara and 5 g of sake lees as a water-soluble binder, and 3 g of a concentrated shrimp extract as a fish-inducing component were put into the mixer and stirred well to prepare a 100 g mixture.

Next, the mixture was poured into a container 7 in which a partition plate 8 shown in FIG. 2 (c) was disposed, and the mixture was left to freeze at a low temperature of -5 ° C. for 3 hours. Then, the frozen mixture is subjected to a vacuum of 0.30 Torr and a shelf temperature of 20 ° C.
For 18 hours to obtain a porous dry solid. (2) Evaluation of dry solid itself The obtained dry solid was 30 g. That is, it indicates that 70 g of water contained in the mixture was sublimated. In addition, although a large number of micropores were observed in the appearance of the dried solid, little change in volume was observed.

From the above, the dried solid is made of a porous material having innumerable fine pores, and since the volume does not change before and after freeze-drying, the space volume ratio occupied by the fine pores is about 70%. (Volume ratio occupied by sublimated moisture). (3) Evaluation of dried solids as sowed bait Next, a comparative test with frozen shrimp was performed. 1. Fish-collecting effect The fish-collecting effect was observed by dropping it on a carp (about 5 years old fish) in a pond.

After 30 g of the dried solid material prepared in the above (1) was put into the ponies and dropped into the pond, carps gathered around the dried solid material for a while. It was about 20 minutes when the gathering time was measured. On the other hand, when 30 g of the frozen shrimp were put into the prawn and dropped, carps similarly gathered around the shrimp, but the gathering time was about 5 minutes. From this,
It can be seen that the dried solids have a better fish collecting effect than the frozen shrimp.

2. Convenience We compared the simplicity of fishing with sabiki on the wharf. The dried solid matter may be simply put in the squid basket. This took less than a minute. On the other hand, frozen shrimp are put in a bucket, pulverized with a knife to a size that can fit into a makiego, and then put into a makiego. This took at least 5 minutes. From this, it is apparent that the dry solid is more convenient in use.
In addition, when the dried solid material is used, equipment such as a bucket and a knife as in the case of using a frozen shrimp is not required, and the hands are not stained, so that it can be handled very easily.

3. Amount of usage The amount of usage when one hour of fishing with sabiki was performed at the same wharf was compared. The volume of the squid was about 15 g for the dry solid and 50 g for the frozen shrimp. Then, every time there was no more bait from the corn basket, fresh bait was replenished and put into the sea without considering replacement of the bait.

As a result, when 15 g of the dry solids were put into a seaweed basket and introduced into the sea, the dry solids disappeared in about 5 minutes. That is, 12 shots were taken in one hour (about 5 minutes per shot), and the consumption of dry solids at that time was 180 shots at 12 shots × 15 g.

On the other hand, when 50 g of a frozen shrimp was put into a sea lion and put into the sea, the frozen shrimp disappeared in about 2 to 3 minutes. Accordingly, 24 shots were taken in one hour (about 2-3 minutes per shot), and the consumption of frozen shrimp at that time was 1200 g with 24 shots x 50 g. From this, the use amount of the dry solid was able to be significantly reduced.
