In the method, copper ions which are effective in fish diseases are used, because the copper ions are also effective in annihilating the red tide, and a pair of electrodes for a metal wire net made of titanium platinum plating is installed in a cooling sea water pipe, for applying electrical shock to cell membranes of the red tide and immediately annihilating the same, and the power is applied thereto together with a copper ion generation device, copper ion discharge water that has thereby annihilated the red tide is discharged into the sea, and also the annihilation of the red tide is carried out while towing the copper electrode net and running to and from a fishing ground, and dissolved oxygen is supplemented from a lower surface of the fish-farming net cage to revive the dying fishes, and a buoy, which has copper electrodes suspended therefrom and is equipped with a solar battery, is provided outside the net cage for preventing the red tide from invading into the net cage.

Description

The number of incidents in which plankton's toxicity kills important cultured fish such as hamachi and hits fisheries has been increasing recently, but no measures have been taken. Red tide is a phenomenon in which planktonic organisms in the sea grow and color the seawater as a result. Typical examples include diatoms, dinoflagellates, and rafoid algae. The most common damage to cultured fish shellfish is the dinoflagellate genus Gymnodinium (Kalenia). Although he is dead due to abnormal respiratory function, there is no way to minimize damage. As a preventive measure for this, treat the fish disease without harming the fish and destroy the red tide plankton's cell membrane to protect the ikesu fish by killing the incoming red tide without affecting the surrounding environment It is related with the improvement method of the prior art of killing quickly and easily and making it widespread.

Since the red tide is a single cell and can be easily killed by attacking the water channel of the cell membrane, it is instantaneously killed by applying direct current to the electrode pair consisting of a titanium platinum mesh wire net installed in the seawater cooling water path taken by the fishing boat Then, it is sent from the tank to the pump on the ship, and the water inside and outside the tank is stored by a solar cell, and through a polarity switching type copper ion generator composed of a plurality of copper electrodes, the red tide killed by copper ions is always 100% and a wide sea area The towed rope is towed with a combination of a titanium platinum mesh wire electrode pair and a copper electrode pair net that has been towed to the middle layer while spraying the drainage on the sea surface with a spray gun to kill the red tide around the fishery area. By scouring the copper ion that kills the red tide from the pipe attached to the seawater while discharging it, the red tide group in the middle layer is destroyed to a low concentration and the red tide It proposes a novel technique according to the prior art improved method of it becomes possible which can grow to be a safe ikesu fish to make connexion not be dangerous Chikayo.

The marine water standard for copper ions is 30 ppb.

The fatal death of hamachi, etc., occurs when the oxygen consumption increases rapidly about 4 times the normal value, then decreases to about twice the normal value and then died after 1 to several hours. It is said that the dissolved oxygen level which raises a function and causes suffocation of a fish rises relatively. If such an abnormality in the respiratory mechanism can be prevented, death from death can be reduced, so that death can be reduced by supplying copper ions in the IKES that can instantaneously kill red tide while having a therapeutic effect on fish diseases.

Even if there is sufficient oxygen supply and oxygen diffuses from the eyelids and body surface, if it can be supplied to match the oxygen consumption of the tissue, death can be reduced, so multiple oxygen supply ports are provided at the bottom of the IKES so that the inside of the IKES If abnormalities are detected, oxygen supplementation and the above-described copper ion drainage treatment effect can be performed, thereby reducing mortality.

When the equipment of the air compressor that can replenish dissolved oxygen to the fish ikesu on the fishing boat is installed, the red tide is killed by sprinkling copper ions from the pipe under the ikesu to replenish and relive the fish before the death of the ikesu At the same time, dissolved oxygen can be replenished and fish can be recovered and recovered from death by the effect of fish disease treatment.

In addition to the technology that destroys the red tide cell membrane that passed through the titanium-platinum-plated wire mesh electrode pair and instantaneously kills it, and the conventional technology of copper ion red tide killing and therapeutic effect, it newly reduces the mortality of fish and regenerates it. To provide improved technology. By destroying the dense communities in the middle and bottom layers of the red tide, it is possible to obtain a low concentration of red tide that does not affect ikesu on the surface of the sea. It is to solve by improvement technology.

It is unimaginable for fishermen to lose their catch due to the aging and lack of successors, and the feeling that fish raised in the corner will be destroyed by red tide. Karenia Mikimotoi grows in the middle and bottom layers and becomes patchy and repeats vertical movement, so it is difficult to determine the color of seawater when observed from the sea surface. From the pipes tied to the ropes attached to the copper electrode network that mixes and supplies the air containing the dissolved oxygen and the discharge water of the copper ion generator so that the red tide can be killed at the bottom of the IKES. By providing a plurality of outlets to kill the dense red tide colonies and blowing them out, if the red tide is divided to a low concentration, the red tide rises and even if it hits the ikes, it will be reduced to a harmless density, so it can be protected. For intrusion from the outer periphery of the IKES, a plurality of electrode rods that can generate copper ions from the copper electrode by always energizing by stacking solar cells on a floating buoy and switching the polarity periodically so that the copper electrode becomes the anode Providing a new technology that can kill and protect against the red tide that attacks every year for a long time by using the droop.

In the sea area other than Ikes, the stern moves while sprinkling the sea surface with a water gun with a mixture of copper ion-containing seawater of a copper ion generator mounted on a fishing boat and sterilized seawater energized by a titanium platinum mesh wire mesh electrode pair. The towed rope that was hung from the towed combination of the copper electrode net and the titanium-platinum metal wire electrode pair made it possible to carry out the dead sea sweeping work of the red tide. Minesweeping in the middle and bottom of the red tide is an area that fishers are good at, and the depth can be adjusted by red tide information. A new technology that allows pipes to be attached to the towing line and sprays the above-mentioned joint sterilized seawater to destroy the dense red tide clusters in the middle layer and destroy them so that even if the red tide rises up to Ikes, fish can be killed at a low density. Solvable.

Even if a red tide attack is seen, the use of the present invention provides a sense of security in the fishing industry and increases sales of IKES fish farming, so it is special because it is composed of titanium and copper, which are inexpensive and can be used for a long time Even if a red tide is seen, it will change to wait for the end of the fishery without taking any special measures.

EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited thereto.

Carenia and Mikimotoi were severely damaged in various places, but in the killing test of Karenia and Mikimotoi off Ube, Yamaguchi Prefecture, they passed through a titanium-platinum metal wire electrode pair and instantly died and were completely disassembled one day later.

With copper ions, Karenia Mikimotoi was killed with copper ions at 30 ppb.

The effect of copper ion on the treatment of fish disease has made it possible to eliminate the death from IKES accommodation.

Fish ikesu in various parts of Japan is an important resource, and the disappearance of fish that have been cultivated for many years is indispensable for nutritional supplementation as a national protein source, so the Ministry of Agriculture, Forestry and Fisheries is also considering measures.
