Description

Detailed Description of the Invention

[0001]

The present invention relates to sterilization of seawater or freshwater of cultured fish, sterilization of drinking water used for livestock production of pig farms, poultry, etc., and control and prevention of harmful insects such as fruit trees, and highly safe sterilization. , Algaecide material.

2. Description of the Related Art It is well known that, in the age of 200 nautical miles, the fishing industry has shifted from the fishing industry to the fishing industry to produce fisheries, and in particular, the aquaculture industry has become popular. However, as the production volume increased, the fishing ground environment deteriorated and various fish diseases began to occur. As a countermeasure against this, drugs such as antibiotics for marine use are administered, but as a result, antibacterial action occurs, so it is necessary to develop new drugs against it, and now we are in a state of fish disease and drug weasel. It's no exaggeration to say.

Recently, aquaculture of high-grade fish has been particularly popular, and the most prominent ones are flatfish and puffer fish. However, since these fishes are nervous and have a weak outer coat, it is easy for parasites such as nematodes and gills to parasitize, and drugs such as formalin are used to exterminate them. There was a risk. Moreover, when these chemicals are used, the shock is great and the physical strength of the fish is exhausted. In addition, the food is badly eaten for a few days, and in the summer when the water temperature rises, considerable death is seen. Moreover, it is more difficult in puffer fish culture, and meshing due to stress occurs. When this begins, it will cause mouth rot and will be completely untouched, and most of it will die. It is also true that these things put pressure on the management of aquaculture fishers.

Recently, similar problems have occurred in the livestock industry. The best of them is pig farming. In particular, in the case of diarrhea occurring in piglets aged 2 to 3 months, when one of the pigs becomes ill, it will be infected and most of them will die. As a preventive method, there is no way other than disinfection of pig houses, and there is no way to deal with it.

In the case of poultry farming, it has become common for adult birds to suddenly die, but it is also true that the causes of these are completely unknown and therefore management is unstable.

In the case of an orchard, for example, slugs occur in the vines from early spring to summer, and when the body fluid produced by the slugs adheres to the trees, the parts may turn black and die at times. It's a cleanup.

In the case of persimmons, shellfish and worms parasitize. Since the mollusk moth adheres to the tree and absorbs the sap, the high-grade Fuyu persimmon loses its sweetness, and at the same time, the weight becomes worse.
In addition, if the worms parasitize, the forehead part will rot and the fruits will increase, resulting in a decrease in yield. Therefore, disinfection is required several times a month, which is a labor-intensive task. These are one of the factors that make the management of the growers unstable.

[0008]

However, the above-mentioned measures against fish diseases and the disinfecting and sterilizing methods described above have a poor sustaining effect of the chemicals and are highly dangerous, and there is a problem in their safety. Further, there is still no known drug that suppresses biting of blowfish, diarrhea of piglets, and sudden death of chickens.

[0009]

The above-mentioned problems of the prior art can be solved by using, for example, a sterilizing / algicidal material produced by the production method according to the present invention. The metal used for the sterilization and algaecidic material of the present invention may be any metal containing 80% or more of copper, and particularly preferably 99% or more for fresh water. Further, as the metal to be bonded to the alloy lump and the copper lump,
There are platinum, gold, palladium, silver and the like, and any of them may be used, but silver is particularly preferable in terms of price. Further, it goes without saying that another metal may be used as long as it is a metal that promotes the elution of the alloy lump and the copper lump.

The greatest feature of the sterilizing / algicidal material of the present invention is that
This is to easily elute a trace amount of copper ions regardless of seawater or fresh water by joining metals having different potential differences to alloy lumps or copper lumps. Eluted copper ions are excellent in bactericidal properties, algicidal properties, and safety and become essential minerals for fish and animals. It is also useful in controlling and preventing parasitic pests in fruit tree cultivation.

[0011]

The copper produced by the production method according to the present invention is
By sterilizing by joining platinum, gold, palladium, silver, etc. to a metal mass containing 0% or more, and bringing the algaecide material into contact with seawater and fresh water, copper ions are easily eluted to cause pathogenic bacteria and algae in water. It exhibits a bactericidal action that kills. In addition, the action of copper ions exerts an action of promoting digestion and absorption, and at the same time, in order to suppress stress, it is possible to cultivate a healthy fish in which a helminth and a gills are not attached. Also, in pig raising, the intestinal regulating action enables healthy pig raising with no diarrhea. Also, in poultry farming, the action of copper ions promotes growth from the brooding stage to the adult season and suppresses stress, thereby enabling healthy poultry farming. In the orchard, copper ions act to prevent slugs, and their bactericidal action extinguishes shellfish, helminths and the like and promotes fruit growth. In addition, it has a function of preventing the generation of algae in the pond water of fishponds, parks, etc. by the algicidal action.

EFFECTS OF THE INVENTION When the sterilizing and algicidal material produced by the production method according to the present invention is used for culturing flounder, puffer fish and the like as shown in Examples 1 and 2, the fish is stable without causing stress. It can be bred in the condition. Also, there was almost no death during the experiment. On the other hand, when the copper alloy of Comparative Example or only copper was used, there was no effect at all and mortality due to attachment of ascites, nematodes, and meshing due to stress occurred.

Next, when the sterilizing and algicidal material produced by the method according to the present invention is used for pig raising and poultry raising as shown in Examples 3 and 4, for example, pigs do not cause diarrhea and chickens are stressed. He did not wake up and did not die suddenly. On the other hand, when only the copper of the comparative example was used, the effect was not exhibited at all, the growth was poor, and mortality was also considerably observed.

Next, when the sterilizing / algicidal material produced by the production method according to the present invention is used for watering fruit trees as shown in Examples 5 and 6, for example, slugs do not parasitize in grapes, In addition, oysters and worms do not parasitize persimmons, so high yields can be obtained. On the other hand, when only the copper of the comparative example was used, there was no effect at all, and slugs, shellfish, helminths and the like were likely to parasitize and the yield was considerably lower.

Further, it goes without saying that the dimensions of the metal plates, the number of combinations, and the dimensions of the container for storing these metal plates shown in each embodiment are not limited to these.
