Description

  The present invention relates to a ceramic, an aqueous solution, and a method for culturing seafood using the same, which are used in a fish farm or a fish tank in which a sea or a pond is partitioned by a net or the like.

  In the conventional method for culturing seafood, the sea or pond is divided into nets and sacrificed, or seawater or fresh water is stored in an aquarium, and for example, if it is a fish of seafood, the fry is released. Then, while swimming the fry, feed and grow it to make it an adult fish, and capture and ship this adult fish. Therefore, for the fishermen, how the fry can be grown and shipped as adults without causing the larvae or juveniles to die during the growth greatly affects the catch and profit.

  In order to sterilize microorganisms parasitic on gills and the like that cause death and parasites in organs, there are aquaculture companies that immerse cultured fish in a formaldehyde solution or the like.

  However, formaldehyde is highly toxic and kills microorganisms and protozoa that parasitize the cultured fish, but formaldehyde may remain in the organs of the cultured fish. Since formaldehyde has carcinogenicity, it enters the human body when eating cultured fish and is extremely dangerous.

  In addition, when a farmer immerses a cultured fish in a formaldehyde solution and returns the cultured fish to the ginger, the farmer may put seawater in which the formaldehyde solution is dissolved together with the cultured fish. As a result of this sterilization method, there is an oyster shell farm for producing pearls near a farm that is sterilized using a formaldehyde solution. It flowed into the field and killed Akoya oysters, which became a social problem.

  Furthermore, the seawater is contaminated by the formaldehyde solution and the plankton that the small fish and shellfish eat are killed, so the growth of seafood near the sea deteriorates and even the ecosystem is destroyed.

  It is also required from the aspect of influence on the human body and environmental conservation to perform such aquaculture that does not require dangerous formaldehyde.

Patent Document 1 discloses a culture method that does not use formaldehyde or antibiotics. The aquaculture method described in Patent Document 1 uses a fluid machine that causes a circulating water flow with a rectifying plate that is greatly spread and floated in water to raise the bottom water to the surface of the water. Exposure to ultraviolet rays prevents rot such as leftover food.
Japanese Patent Laid-Open No. 10-276608

However, since the culture method described in Patent Document 1 needs to use a fluid machine, the scale of the farm is increased and the cost is increased. Moreover, since the drive motor is used to generate the water flow, it is necessary to lay a long power cable for supplying power to the fluid machine to the aquaculture farm, which requires laying costs and is not easy to maintain.
Therefore, it is not suitable to cultivate seafood using such a fluid machine because it can be cultivated safely, but cannot be carried out easily.
Therefore, the present invention can be easily carried out when cultivating seafood, eliminates the need for highly dangerous formaldehyde, is highly safe for human bodies and seafood, and is environmentally friendly. An object of the present invention is to provide ceramics, an aqueous solution, and a method for culturing seafood using the same.

  The ceramic of the present invention is formed by molding and firing a mixture containing a quartz rock powder produced in Takachiho Town, Miyazaki Prefecture, and a mixture containing clay.

  Quartzite rocks produced in Takachiho Town, Miyazaki Prefecture are called suspected stones (trademark). Its components are silicon dioxide, manganese oxide, sodium oxide, magnesium oxide, aluminum oxide, diphosphorus pentoxide, sulfur oxide, potassium oxide, calcium oxide, titanium dioxide, iron oxide, zinc oxide, iridium oxide, strontium oxide, zirconium dioxide Is included.

  Unlike the tourmaline, in which far infrared rays are not generated unless heated to 100 ° C. or higher, the ceramic obtained by firing the pseudolite and clay can generate far infrared rays at room temperature. Far-infrared rays have a long wavelength, so they tend to propagate in the body of seafood even in water. If this ceramic is introduced into a fish cage or aquarium where fish and shellfish are cultivated, far-infrared rays generated from the ceramic propagate through the body of the fish and shellfish and activate the body water of the cells or promote blood flow. So you can keep the health of seafood.

  In addition, since suspicious stones generate negative ions, by introducing this ceramic into a sacrifice provided in the sea, the earth current can be discharged in water and the natural environment can be restored.

  By making ceramics by mixing and molding suspicious stone powder having such a function with clay and firing it, it can be placed in a water tank or a cage for aquaculture, when it is formed into blocks, or particles Can be sprayed.

  Further, the ceramics can be placed in a container formed of a net or the like and hung on a sacrifice.

  The ceramic preferably contains divalent iron or trivalent iron. When ceramics containing divalent iron or trivalent iron are introduced into a cage or aquarium, divalent iron or trivalent iron works to reduce fresh water and seawater, so that residual foods are less likely to spoil, resulting in water pollution. Can be suppressed.

  Moreover, it is desirable that the ceramic is molded into a spherical shape or a ring shape. Since the surface area per volume can be increased by forming the ceramic into a spherical shape, it is more effective. Further, by making the ring shape, the ring-shaped ceramics can be knitted together when producing a net surrounding the sacrifice. By weaving ring-shaped ceramics into the net, it is possible to evenly arrange the ceramics around the sacrifice.

  The aqueous solution of the present invention comprises quartz rock powder produced in Takachiho Town, Miyazaki Prefecture. The quartz rock powder produced in Takachiho Town, Miyazaki Prefecture, called Suspicious Stone (Trademark), has the above-mentioned effects. By using an aqueous solution containing this powder, the fish and shellfish being cultured can be added. By swimming, it can be taken into the body of seafood.

  Incorporation of the suspicious stone powder into the body of the fish and shellfish being cultured makes it possible to further activate the body water of the cells and promote blood flow.

  In addition, if you store an aqueous solution mixed with suspicious stone powder in the aquarium and swim the cultured seafood in this aquarium, the suspicious stone powder will be stirred in the aquarium, so it will not settle. An evenly distributed state can be obtained.

  The aqueous solution preferably further contains acetic acid, a nucleobase, essential amino acids, and vitamin C.

  Here, as acetic acid, rice vinegar, rice bran vinegar, apple vinegar and the like can be used as an aqueous solution containing acetic acid. As the nucleobase, adenine, guanine, cytosine, thymine, and uracil can be used. Essential amino acids include glycine, alanine, serine, proline, valine, threonine, cysteine, leucine, isoleucine, asparagine, glutamine, lysine, glutamic acid, methionine, and histidine. And phenylalanine, arginine, tryptophan, tyrosine, and aspartic acid.

  Since these have a function of promoting the activation of fish and shellfish cells, the health of the fish and shellfish to be cultivated can be maintained.

  The method for culturing seafood according to the present invention includes a step of introducing the ceramics and the aqueous solution described above into a water tank in which fresh water or seawater is stored, and a step of reducing the stored fresh water or sea water by blocking light to the water tank. The method further includes the steps of putting the fish and shellfish cultivated from the ginger into the aquarium and returning the fish and shellfish put in the aquarium to the ginger.

  By introducing ceramics and aqueous solution containing suspected rock powder into a tank containing fresh water or seawater, shielding the tank and blocking light, the fresh water or seawater is released from the quartz rock powder. It is deoxygenated by divalent iron or trivalent iron contained in infrared rays or ceramics and enters a reduced state with a low redox potential.

  By adding the seafood cultured in the fresh water or seawater in this reduced state, the seafood takes this water into the body, so that the body water of the cells can be activated.

  The present invention has the following effects.

(1) According to the ceramic of the present invention, far-infrared rays generated from quartz rocks produced in Takachiho-cho, Miyazaki Prefecture, contained in ceramics propagate through the body of seafood, activate the body water of cells, Because it is promoted, the health of seafood can be maintained. Therefore, immunity against illness is improved, so that sterilization using chemicals or the like becomes unnecessary. Therefore, safety can be improved for the human body and seafood.

(2) By containing divalent iron or trivalent iron in the ceramic of the present invention, it acts to reduce fresh water and seawater, so that residual foods are not easily spoiled and water pollution can be suppressed.

(3) Since the surface area per volume can be increased by forming the ceramic into a spherical shape or a ring shape, the effect can be further enhanced. Also, when molded into a ring shape, it can be knitted into the net surrounding the sacrificial cage, so the ceramics move in the sacrificial cage due to water flow etc. It can be prevented from coming out.

(4) According to the aqueous solution of the present invention, an aquatic solution containing quartz rock powder produced in Takachiho-cho, Miyazaki Prefecture is put into the body of the fish and shellfish by putting the fish and shellfish being cultured and swimming. Quartz rock powder can be incorporated. Therefore, activation of the body water of the cells can be achieved from the body of the seafood, which is more effective.

(5) Since the aqueous solution contains acetic acid, nucleobase, essential amino acid, and vitamin C, it has a function of promoting the activation of fish and shellfish cells. You can stay healthy.

(6) According to the culture method of the present invention, the body water of the cells of the seafood can be activated or the blood flow can be promoted, so that the health of the seafood can be maintained. Therefore, immunity against illness is improved, so that sterilization using chemicals or the like becomes unnecessary. Therefore, safety can be improved for the human body and seafood.

  Hereinafter, ceramics according to embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a ceramic according to an embodiment of the present invention.

  As shown in FIG. 1, a ceramic 1 according to an embodiment of the present invention is a particle formed in a spherical shape having a diameter of 7 mm. This size is related to the size of the fish and shellfish to be cultivated, but is preferably about 5 mm to 10 mm so that the fish and shellfish eat the ceramics 1 to have less influence.

  This ceramic 1 is made of 80% quartz rock powder from Takachiho Town, Miyazaki Prefecture, called suspected stone, 5% divalent iron and trivalent iron, and 15% clay as a binder. These are mixed and fired at about 1150 ° C. By using ceramics, it is possible to evenly mix the powders of pseudolite, divalent iron, and trivalent iron.

The components of the suspicious stone powder are shown in Table 1.

Next, the aqueous solution which concerns on embodiment of this invention is demonstrated.
The aqueous solution is a mixture of suspicious stone powder, acetic acid, nucleobase, essential amino acid, and vitamin C in water.

About 2 kg of suspicious stone powder is used in this aqueous solution.
As acetic acid, 1.7 liters of each of rice vinegar, straw vinegar, apple vinegar and an aqueous solution of citric acid are mixed to use a total of 8.5 liters. As the nucleobase, a mixture of 5 g of adenine, guanine, cytosine, and thymine powder is used. Essential amino acids include glycine, alanine, serine, proline, valine, threonine, cysteine, leucine, isoleucine, asparagine, glutamine, lysine, glutamic acid, methionine, and histidine. A mixture of 2.5 g each of phenylalanine, arginine, tryptophan, tyrosine, and aspartic acid powder is used. Vitamin C uses about 10g of powder.
By mixing and stirring these in 10-15 l of water, the aqueous solution according to the present embodiment can be obtained.

  When seafood metabolizes, it requires nucleobases and essential amino acids. Metabolism is carried out by ingesting these from food or synthesizing them in the body. By mixing this nucleobase and essential amino acids in an aqueous solution and supplementing the seafood, the metabolism of the seafood is promoted. Can be made.

  A method for cultivating seafood using ceramics and an aqueous solution according to the embodiment of the present invention configured as described above will be described with reference to FIG. FIG. 2A to FIG. 2D are diagrams for explaining a method for culturing seafood according to an embodiment of the present invention.

In this embodiment, a yellowtail will be described as an example.

  The water tank 10 introduces the ceramics 1 and the aqueous solution 2 into the stored seawater 11. The amount of ceramics 1 is 4 kg per 1000 kg of seawater 11. The amount of the aqueous solution 2 is 6 to 10 l per 1000 kg of seawater 11.

  As shown in FIG. 2B, the opening portion of the water tank 10 is covered with a light blocking sheet 12 so that the water tank 10 into which the ceramics 1 and the aqueous solution 2 are introduced does not receive light. Leave in this state for about 24 hours.

  By leaving for 24 hours in a state where light to the water tank 10 into which the ceramics 1 and the aqueous solution 2 are introduced is blocked, the seawater 11 is emitted from the quartz rock powder of the ceramics 1 or is contained in the ceramics. Due to the valence iron or trivalent iron, the redox potential of the seawater 11 is reduced.

  As shown in FIG.2 (c), the bristle 13 is put into the water tank 10 left for 24 hours. By inserting the yellowtail 13 into the seawater 11 in this reduced state, the yellowtail 13 takes this water into the body, so that the body water of the cells can be activated. Moreover, since the yellowtail 13 swims, the aqueous solution mixed with the suspicious stone powder is agitated in the aquarium 10, so that it can be uniformly distributed.

  As shown in FIG. 2 (d), after the yellowtail 13 is allowed to swim for 30 to 40 minutes in the water tank 10 in this state, the yellowtail 13 is taken out with a rake net or the like and returned to the sacrifice.

  It is more effective to put it in the aquarium 10 into which the ceramics 1 and the aqueous solution 2 are introduced, such as once for fry, once for Inada as a juvenile, and once for adult yellowtail. Can maintain the health of yellowtail.

  As described above, when the seafood is cultured using the ceramics and the aqueous solution of the present embodiment, the body water of the cells of the seafood can be activated or the blood flow can be promoted. Can keep the state. Therefore, immunity against illness is improved, so that sterilization using chemicals or the like becomes unnecessary. Therefore, safety can be improved for the human body and seafood.
