方法があることが知られている。2. Description of the Related Art In recent years, in the aquaculture fishery promoted as a redevelopment of Japanese fishery by withdrawal from the pelagic fishery, the increase of fish diseases is progressing with the pollution of coastal seawater and river water.
It is becoming a serious problem. Although the number of aquaculture and fisheries has increased rapidly in recent years, the safe and easy treatment method for fish diseases has not yet been established. Conventionally, it is known that the concentration of copper ions in natural seawater is 3 ppb, but fish parasites grow and survive at this concentration. It is known that there is a method of exterminating parasites with a chemical bath of copper sulfate, formalin or the like to treat fish diseases when these adhere to and parasitize fish and cause fish diseases.

法を提供することを目的とする。However, there are the following problems in the extermination of parasites using copper sulfate or the like which has been conventionally used. That is, since the easy use of copper sulfate or the like is dangerous, the handling method must be well known, and the general use is not made. This is because the amount of addition based on the ppm unit and the high technical skill such that the chemical bath must be performed within 3 minutes are required.
Further, since a large amount of waste liquid is used, there is a problem that this waste liquid treatment must be solved technically and costly. The present invention has been made by paying attention to the conventional problems as described above, and it is possible to obtain an excellent fish disease treatment effect which is safe for both humans and fish, and it is possible to reduce the cost. It is also an object of the present invention to provide a method for treating fish diseases that can be carried out with an easy handling technique.

のとする。Next, a third embodiment will be described with reference to FIGS. The drawing shows a copper electrode and iron electrode in natural seawater or river water in a floating tank that has an openable water tank with a fish passage so that it can move adjacent to a floating cage in the sea or river water. This is a method of exterminating and preventing fish parasites by supplying a direct current with a copper ion concentration adjusting generator provided in the above to adjust the copper ion concentration of the floating tank internal water to a high concentration. The copper ion adjusting and generating device 5 is provided on the land or above the floating tank 9, and is connected to the copper electrode 5a by an electric wire 6 from this. Since the material of the floating tank 9 is made of iron, the iron electrode is not specially provided in this embodiment, and the iron electrode is provided only when the material is a non-conductive tank such as FRP. The structural action of the copper ion concentration adjusting and generating device is the same as that of the first embodiment, and therefore its explanation is omitted. Fig. 3 shows the mooring condition when cultivating or cultivating fish in the floating cage as A, and the floating tank generates copper ions in the internal seawater or river water by the copper ion concentration adjustment generator, and the mooring is still in progress. It shows a moored state that does not own farmed fish. That is, the floating cage 8 has a cage net 8a that surrounds the fish 3 and has a work passage 8b in the upper portion thereof. The opening of the cage net 8a is fixed by a stopper-8c provided in the work passage 8b. In the fish cage net 8a containing fish, fish parasites 4 in the sea or river water are freely fished in the fish cage net 8a.
It passes through a and attaches to and parasitizes fish 3. The floating tank 9 has one or several openings on the adjacent floating cage side,
By connecting the leading end of the fish cage net 8a to the fish passage 9a, the fish can float freely between the floating fish cage 8 and the floating tank 9. In the case of exterminating fish parasites, the stopper 9c of the floating tank 9 is pulled up and the lower part and the side of the cage net 8a are lifted upward.
Since the fish naturally moves from the fish passage 9a into the floating tank 9, the fish passage 9a is closed after the movement is completed. Then, after confirming that the fish parasites have been killed by the copper ion effect by the internal water having a high copper ion concentration by energizing the electrodes in advance, the compressed air is sent to the air tank 9d provided at the bottom of the floating tank 9 to float. By inclining, the fish are moved from the floating tank 9 to the floating cage 8. 5 and 6 show the moving and housing state of fish. The movement of fish is
In addition to compressed air, a cage net with the same structure as the floating cage is also installed in the floating tank and can be moved by lifting it. The structure of the floating tank can be changed.

る。Since the method for treating fish diseases according to claim 1 of the present invention employs the above method, compared to the conventional difficult handling method using a chemical bath such as copper sulfate or formalin, labor cost, and drug cost. As a result, it is possible to continuously and safely use it with a simple operation, and the power consumption can be extremely reduced. In addition, since the removal and prevention of excellent fish parasites can be achieved without changing the components of natural seawater, except that the concentration is higher than the normal copper ion concentration in natural seawater,
It is possible to obtain sound seedling production and shipping in all the aquaculture processes from fry to adult fish.
In the method for treating fish disease according to claim 2 of the present invention, since the method is adopted, copper ions are generated in the inside of the filtration device to make the copper ion concentration high, thereby preliminarily in natural seawater or rivers and breeding. By collecting the parasites growing in the aquarium at the surface layer of the filter and intensively applying the copper ion effect thereto, the extermination efficiency of the parasites is increased. When a sand filter is used, since the sand filtering capacity has a collection efficiency of 10 micron particles, larvae of 30 microns and adults of 50 to 300 microns are completely collected on the surface layer, so that copper ions are killed. A control valve that gives an effect and discharges to the outside of the sand filter completely prevents contamination on the drain side.
That is, it is possible to obtain the effect that the condition of the fish can be completely satisfied with respect to the water quality. Claim 3 of the present invention
In the method for treating fish disease described, since the above method is adopted,
To exterminate and prevent fish parasites already parasitized in the sea or river water by moving fish that are kept in floating cages in natural seawater or river water to a floating tank that stores high concentration of copper ions. In addition, it is possible to obtain the effects that the cost can be reduced as compared with the conventional methods such as a medicinal bath, and that a large amount of parasites can be removed and prevented at once. In the method for treating fish diseases according to claim 4 of the present invention, since the method is adopted, the fresh seawater and the high-concentration salt water produced by the natural seawater or river water and the reverse osmosis membrane type seawater desalination apparatus provided in the moving vehicle are copper respectively. By supplying a high ion concentration, it is possible to easily treat fish diseases at a site where fish are cultivated on the coast or remote areas. In addition, depending on the location conditions, the quality of water promptly responds to fish treatment,
Since it is possible to supply water, it is possible to manage the aquaculture business by overcoming the disadvantage of location conditions, and it is possible to significantly reduce the cost of fish disease treatment even in remote areas. can get. In the method for treating fish disease according to claim 5 of the present invention, since the method is adopted, unlike a moving vehicle, by adjusting the copper ion concentration of fresh water and high-concentration salt water in a tank having a large capacity as a stationary type to a high concentration. Optimal for aquaculture operations that use extremely large amounts of water. In addition, the supply of fresh water is extremely difficult in the coastal areas, and the economic effect is opened because the use of salt in well water is restricted, so that it is possible to control fish parasites and prevent fish diseases. A synergistic effect with the possible effect is obtained. In the method for treating fish disease according to the present invention, since the method is adopted, the concentration of copper ions generated in the cage is always lacking even when the cage net is made of nylon or other materials conventionally used. It is possible to prevent marine organisms from adhering to the net of the cage by adjusting it without any adjustment. Therefore, the tidal flow is good,
Moreover, the occurrence of parasites is reduced due to copper ions diffusing into the river water in the sea, and the decay of sown bait is also reduced.
Since the net of the stored fish does not attach to the marine life, the product price of the cultured fish can be increased. Further, when the net material used conventionally is iron, an increase in the weight of the cage when it is a metal material such as copper, corrosion by seawater, difficulty of net raising work, etc. occur, but in the present invention, a plurality of copper electrodes, Since only the iron electrode is arranged, it is possible to obtain the effect that it is possible to use a strong mesh material such as nylon which is lightweight and has good flowability.
