Description

Ice manufacturing method for providing disinfectant in water while maintaining a mild condition and administration method using the same.

In order to prevent or treat fish diseases of animals living in aquaculture farms, the present invention maintains a mild atmosphere so as not to affect farmed fish during the process of administering the disinfectant in water, and finally distributes the disinfectant at a certain concentration in the water. It is a technology related to ice, its manufacturing method, and its administration method to provide as much as possible.

The history of aquaculture in Korea is relatively long, but in the 1970s, seaweed such as laver and seaweed and shellfish culture such as oysters developed.

In the 1990s, fish aquaculture began to develop in earnest, centering on halibut and rockfish.

The wave of fish culture was caused by a sudden increase in the supply of Chinese live fish as imports of live fish from China increased, although the production of aquaculture increased significantly as the aquaculture of rockfish, which had been mainly performed in Gyeongnam area, expanded to Jeonnam area. As items are gradually diversified and even in cage farming in the open sea, there has been an increasing demand for safe aquaculture production technology and improvement of the fishery environment.

Domestic aquaculture production has continued to increase in the meantime. Although the increase in production in other fisheries sectors has recently been insignificant or declining, the aquaculture sector has continued to increase, with general sponge fishery increasing by 3.2% during the same period, and deep-sea fishery in the same period. On the contrary, considering the 6% decrease, the increase in fishery production in Korea can be attributed to the increase in aquaculture production. do.

Looking at the regional concentration and aging of domestic aquaculture farms, Korean farms are currently concentrated on the southern coast centered on Jeollanam-do and Gyeongnam. As they have been cultivating in one place for a long time, the farms are aging and productivity is declining. As a result, mass mortality problems are occurring frequently due to the occurrence of fish diseases. the current situation.

The problem of occurrence of fish diseases is that fish diseases are widespread not only in seedling production institutions and farms, but also in natural seas due to the release of seedlings. The growing risk of introducing unknown pathogens can be a bigger problem.

In particular, recently, new diseases such as mass death of pearl oysters and halibut anemia have been reported, and viral diseases such as red sea bream irido virus disease and acute viremia (PAV) of barley shrimp caused by imported seedlings have a serious impact on aquaculture management and coastal fisheries. is reaching the

Although most of these fish disease-related measures have been dependent on antibacterial drugs so far, prevention of the use of vaccines due to the increase in resistant bacteria, public health problems, food safety risks due to residual antibacterial agents, and the prevalence of viral diseases that are difficult to treat with drugs. There is an argument that it should be switched to quarantine measures that focus on

Meanwhile, the International Fisheries Service (OIE) enacted the International Fisheries Sanitation Code in 1995 to prevent the international transmission of major diseases, and has requested member countries to comply with this standard. ) The treaty requires each country to take measures to prevent the introduction and export of invasive species, including hospital organisms. Some of the protection laws were amended to introduce an import permit system for aquatic seedlings, including carp, prawns, larvae and fertilized eggs of salmonids.

In May 1999, the Ministry of Agriculture, Food and Rural Affairs submitted and approved the "Act on the Securing of Sustainable Aquaculture Production" to the National Assembly for the purpose of securing continuous and stable production of aquaculture mainly aimed at countermeasures against fish diseases. The goal is to realize appropriate aquaculture within the scope of this, stabilization of aquaculture management, and continuous production, and to develop aquaculture and stable supply of fishery products. Measures research for this is stipulated.

Recently, a number of new diseases are occurring in bacterial diseases, the number of cases of complex infection is high, and the types of diseases that occur by time tend to appear throughout the country, and the frequency of appearance of bacteria resistant to various treatment drugs is also increasing. Various factors are involved depending on the pathogenicity of the bacteria to enter the body of the cultured fish and cause disease. such as culture density and stress factors.

As seafood aquaculture is activated and production increases, the occurrence of diseases in farmed fish has increased. As a result of in-depth research on fish diseases, the number of cases of damage caused by viral diseases also increases, and viral diseases are treated as a treatment method Since there is no such thing, prevention is the best measure.

Currently, bream iridovirus disease and halibut lymphocystisvirus disease are currently a hot issue. The dome iridovirus causes mass mortality in dolphins and infects various fish species, and the However, due to the difference in size and pathogenicity, lymphocytic virus does not cause mass mortality, but it forms a tumor on the body surface of halibut and reduces the value of the product, causing economic loss to aquaculture and fishermen. It is so strong that 100% mortality has been reported in the pathogenicity test of red sea bream and sea bream.

In addition, based on the research results on scutica worms that invade the brain as a result of fish disease and cause mass death, scutica worms invade damaged epithelial or epithelial cells, and infection is limited to the invading site. spreads to brain tissue via the brain ganglion or spinal cord, and the onset of the disease is the same as the higher the breeding water temperature, the lower the dissolved oxygen level, the faster the infection progresses. have.

As mentioned above, during the aquaculture process, aquatic organisms are unable to maintain the balance of the environment, anti-military force, pathogen, etc., and damage to fish diseases is increasing due to deterioration of the breeding environment, an increase in pathogens and a decrease in anti-military force. It is a year-round occurrence, and in particular, concerns about economic loss for aquaculture workers exist due to the mass death of aquaculture organisms due to mixed infection of pathogens or virus infection.

As a means to solve the above problems, the prior art for preventing or treating fish diseases of aquatic animals living in aquaculture farms up to now is as follows.

However, in the prior art as described above, in order to prevent or treat fish diseases of aquatic animals living in the farm, a high concentration of a disinfectant or antibiotic is administered to the water filled in the farm, but finally, a constant concentration of the disinfectant or antibiotic in the water can be maintained. This is done by agitation after administration of a certain level. At this time, the disinfectants or antibiotics administered in the water of the farm are present in a non-uniform high concentration before being stirred. Inhalation causes shock symptoms, fish death due to shock caused by ingestion of high concentrations of drugs, or lack of measures against growth and development deterioration due to shock to prevent normal growth of aquatic animals during the aquaculture process .

Therefore, in order to prevent or treat fish diseases of aquatic animals living in aquaculture farms, when a high concentration of disinfectant is administered to the water filled in the farm, a mild atmosphere in which aquatic animals do not cause shock is provided, while a certain concentration of disinfectant in the water can be maintained. Recognizing that there is a need for improvement measures, the present technology was developed.

As revealed in the above background, the present application directly administers a high-concentration disinfectant to the aquaculture farm from above the surface of the water to prevent or treat fish diseases of aquatic animals living in the farm. If the high-concentration disinfectants introduced into the water make the habitat environment poor due to the shock of the fish while coming into contact with the fish, the body surface of the fish becomes rough, the mucous membrane is damaged, or the fin and gill cells are altered, and oxygen supply is disturbed. It is an invention that started with the recognition of the task to find a way to solve the problem of causing economic loss to aquaculture companies due to the death of a large number of fish due to shock death as the surface of the body turns white and floats to the top of the tank. .

Therefore, the present application provides a mild atmosphere by blocking the administration of a high-concentration disinfectant to the habitat of aquatic animals when administering a high-concentration disinfectant in the water filled in the farm as a means for preventing or treating fish diseases of aquatic animals living in the farm. An object of the present invention is to provide ice that provides a uniform sterilizing power in water so that a sterilizing agent of a certain concentration in water can be maintained, and a method for manufacturing the same and an administration method using the same.

According to the present invention, when ice containing a disinfectant is administered to the water of an aquaculture farm, the ice injured in the water is slowly melted and the disinfectant is also released slowly. Technology related to ice manufacturing method and administration method using the same to provide a constant concentration of disinfectant in the water of the farm, without causing shock symptoms of aquatic animals due to contact with high concentration of disinfectant, and maintaining a docile atmosphere condition The idea is not presented at all, and it is a novel technology that cannot achieve the purpose of the present technology even when the prior art is applied in combination.

Compared with the prior art as described above, the present technology is a means for preventing or treating diseases occurring in fish. When ice with a specific gravity of 1 or less containing a certain concentration of a disinfectant is administered to a farm, the ice slowly melts and the disinfectant is also slowly dissolved. By allowing it to dissolve and release, it provides a mild and docile environment when the disinfectant is put in, so there is no need for a separate facility to supply the disinfectant into the water. It is a novel technology that can mass-produce fish with excellent quality without getting sick by providing an environment.

One embodiment of the technical idea of the present invention is a method for administering a fungicide for preventing or treating fish diseases of aquatic animals living in aquaculture farms, depending on the fish species of aquatic animals living in aquaculture farms. The first step process and the second step process of diluting the disinfectant selected by the first step process with water, and the third step process and the third step of freezing the disinfectant diluted by the second step process to obtain ice containing the disinfectant The fourth stage process is included in which the ice containing the disinfectant made by the process is administered to the aquaculture farm and dissolved and the disinfectant is released into the farm. characterized by the method.

In the disinfectant administration method to which the present technology is applied, the disinfectant selection process of the first step process is copper sulfate, copper chlotide, copper nitrate, formalin (Formaldehyde), acetaldehyde, quinine (Quinine), Nitroimidazole, Melafix, Masoten (Organic Acid Insecticide, Dimethylester of phosphonic acid), Praziquantel, Anthraquinone, Dinatonium Benzoate ( Denatonium benzoate, Methylene blue, Potassium permanganate, Calcium hypochlorite, Sodium hypochlorite, Hypochlorous acid, HClO, Sodium chlorite, NaClO2) chlorous acid (Chlorite, HClO2), benzimidazole, benomyl, carbendazim, thiophanate-methyl. Edifenphos, Mancozeb, Propineb, Myclobutanil, Tricyclazole, Chlorothalonil. Dazomet, isoprothiolane (Isoprothiolane), hydrogen peroxide, hydrogen peroxide, chloramine-T (chloramine-T) at least one disinfectant can be selected and applied to supply the disinfectant in water, and the dilution step of the second step process It can be applied to be used diluted in a concentration range of 50 ppm to 6.5 wt%.

Therefore, the present application is ice containing a disinfectant, and copper sulfate, copper chlotide, copper nitrate, formalin, acetaldehyde, quinine, and nitroimidazole as disinfectants. (Nitroimidazole), Melafix, Masotene (organophosphate insecticide, Dimethylester of phosphonic acid), Praziquantel, Anthraquinone, Denatonium benzoate, Methylene blue (Methylene blue), Potassium permanganate, Calcium hypochlorite, Sodium hypochlorite, Hypochlorous acid (HClO), Sodium chlorite (NaClO2) Chlorite, HClO2), benzimidazole, benomyl, carbendazim, thiophanate-methyl. Edifenphos, Mancozeb, Propineb, Myclobutanil, Tricyclazole, Chlorothalonil. At least one disinfectant is selected from Dazomet, isoprothiolane, hydrogen peroxide, and chloramine-T, and the disinfectant is diluted with water to a concentration of 50 ppm to 6.5% by weight and then frozen. Served with ice with

As a method of using ice containing the disinfectant, a disinfectant selected by the first-step process and the first-step process in which a disinfectant suitable for preventing or treating fish diseases or preventing spoilage of aquatic products and maintaining freshness is selected depending on the fish species of aquatic animals The second-step process of diluting the sterilizer with water, the third-step process to obtain ice containing the disinfectant by freezing the disinfectant diluted by the second-step process, and the ice containing the disinfectant made by the third-step process to produce fish bottles at the farm. It can be used for preventing or treating, or for preventing spoilage of aquatic products or for maintaining freshness of aquatic products.

In the disinfectant dilution step herein, the disinfectant selected in the disinfectant selection step may vary depending on the type of fish in use for preventing or treating fish diseases, and may vary depending on the size of the farm to which the present application is applied, and may depend on the solubility of the disinfectant The concentration of the diluted disinfectant can be applied differently because it can vary depending on it, and it can be diluted preferably in a concentration range of 50 ppm to 6.5% by weight, preferably in a concentration range of 650 ppm to 4.5% by weight, Most preferably, a concentration range of 0.2% by weight to 2.0% by weight is advantageous. When the disinfectant is diluted to maintain a concentration of 50 ppm or less, it does not have any effect on the production of ice containing the disinfectant, and It is possible to sterilize a small aquarium with a small amount of water, but in general, the concentration of the disinfectant is very low in an aquarium or aquaculture of heavy weight or higher, so there is a problem that the possibility of preventing or treating fish diseases is very slim, and the content of the disinfectant is 6.5 weight When diluted to maintain a concentration of % or higher, it can be applied to the prevention and treatment of fish diseases in aquaculture in a relatively large scale. When the concentration of ingredients or salts is high, a lot of energy is required to produce ice with excellent durability. It is preferable to use diluted so as to maintain the concentration.

The freezing step is not particularly limited as long as solid ice can be made from water in which the disinfectant and water are mixed by the sterilizing agent dilution step. If it is desired to be released within ten minutes, it can be prepared in the size of frozen ice in a home refrigerator. Of course, it can be used as

In addition, when the present technology is applied to the field, ice containing the disinfectant may be randomly administered above the water surface of the farm, but the amount of ice containing the disinfectant may be applied differently depending on the contact area of the ice located above the water surface of the farm to the water surface. It may be configured by installing an ice dispenser or a separate support that can properly adjust the height and height of ice containing sterilizing agent inside the aquaculture farm.

Therefore, the present application provides a disinfectant selection step in which a disinfectant is selected to prevent or treat fish diseases according to the type of aquatic animals living in the aquaculture farm; and a disinfectant dilution step to dilute the selected disinfectant with water; and dilution in the dilution step by an ice machine Freezing step for manufacturing the used disinfectant into ice; The process is carried out to obtain ice containing the disinfectant, and when the ice containing the disinfectant is administered to water to prevent or treat fish diseases in the aquaculture farm, the ice containing the disinfectant that floated to the top of the farm surface slowly melts. Through the configuration in which the disinfectant is released slowly together while the disinfectant is administered and diluted, the shock symptoms of aquatic animals that inevitably come into contact with the high-concentration disinfectant do not occur. It can be implemented as a method for producing ice that can provide a disinfectant of the sterilizer to be distributed and an administration method using the same.

As disclosed in the background, the related art of the present application is to prevent fish diseases of aquatic animals in conventional aquaculture farms or to maintain a constant concentration of the disinfectant corresponding to the total storage capacity of the aquaculture farm when treatment is needed. When aquatic animals moving around the time come in contact with hazardous disinfectants, they cause shock symptoms, and inevitably, a large number of fish are killed by shock due to excessive intake of high-concentration disinfectants, or aquatic animals are affected by abnormal growth during the aquaculture process. Although there was a big problem that it can cause great health and economic damage, the present invention provides an effect of preventing or treating fish diseases of inhabiting animals because ice containing a disinfectant is supplied to aquaculture farms.

In this application, when ice containing a disinfectant is administered to the water of a farm, the ice containing the disinfectant floated on the top of the water is slowly melted and the disinfectant is also slowly released together. For the future development of the aquaculture industry by providing an ice manufacturing method and an administration method using the same to provide a constant concentration of disinfectant to the water of the farm while maintaining a mild atmospheric condition so as not to cause shock symptoms of aquaculture fish species It is expected to provide great health and economic effects.
