Abstract

PROBLEM TO BE SOLVED: To solve such problems that there is a prime task of breaking down a current state that the management of a cultured laver fishery household is thrown into serious crisis, and activating production, in view of the fact that laver culturing net damage by fish caused by the development of a fishing ground making technology occurs frequently, and additionally, protection of birds progresses and laver culturing net damage by foreign birds occurs simultaneously.SOLUTION: A laver culturing net adopts a technology of preventing damage by fish and birds, and additionally, a seawater electrolytic technology decreasing even the number of bacteria adhering to a laver leaf body. Furthermore, an electric power which generates ≥30 ppb of copper ion having effect of killing competitive plankton in red tide as a laver production inhibitor is performed by electric power with a solar power generator and a wind power generator.

Description

  The present invention relates to the control of production-inhibitory factors by plankton such as prevention of feeding damage of birds and fishes of cultured laver nets, control of attached bacteria of laver leaves, and red tide.

  For floating laver nets, floating floating laver nets that are developed offshore and dry-sealed laver nets in shallow water are used as a method according to the region. In any method, nutrients contained in seawater with bacteria attached to laver leaf bodies arise, so recently acid treatment method called activity that cleans laver leaf bodies by acid treatment and controls bacteria attached to leaf bodies. Is used.

The shallow-sea cultivated laver net has a problem that requires countermeasures since it has had an impact on the production of clam shellfish in the bottom mud since the activation method was used.

As an improvement measure, hypochlorous acid is generated by electrolysis of on-site seawater using solar energy or combined with wind power, thereby killing the number of bacteria attached to laver. In order to prevent the invasion of birds and fish that damage the seaweed at the same time, batteries, polar switching devices, etc. are placed on the work area or buoy around the sea area, and the titanium wire is platinum-plated. A method of supplying a direct current between the electrodes was adopted.

If the base that supplies the direct current is energized from the copper anode as a copper rod, the copper electrode generates copper ions. Due to the sterilization effect of 30 ppb or more by the copper ions, the production inhibitory factor due to plankton such as attached bacteria and red tide is killed. A method that enables control is adopted.

About the extermination effect of cultured seaweed settled diatoms using seawater electrolyte-1 (mechanism)

The problem to be solved is that the titanium wire is oxidized by the direct current in the seawater and the conduction is reduced, so that the polarity switching device always causes seawater electrolysis from the anode using a platinum-plated titanium electrode. Therefore, it is possible to control the plankton such as red tide at the same time to reduce the number of bacteria attached to the laver leaf body as well as to prevent the invasion of birds and fish that damage the cultured laver leaf body by generating hypochlorous acid.

The present invention has an effect of electrolysis by increasing the voltage of the titanium wire platinum plating electrode and switching the polarity arbitrarily in order to prevent the invasion of birds and fish that feed on the cultured laver and simultaneously reduce the number of bacteria attached to the laver leaf body. The most important feature is that a copper rod can be placed on the electrode to generate copper ions and to control the death of plankton such as red tide that attacks in the lu field.

It is the sterilization effect of hypochlorous acid, which is the effect of the direct current electrolysis, that prevents the invasion of birds and fish that damage the cultured laver of the present invention, and this can be increased to a concentration of 300 ppb or more. For example, there is an advantage that the number of bacteria adhering to the leafy lobe can be reduced simultaneously with the death of the red tide plankton.

Conventionally, the decrease in nutrients in seawater is due to excessive water quality control effects, and attempts have been made to release water from dams on land to supplement nutrients. The possibility of killing red tide plankton through the generation of high-concentration hypochlorous acid and copper ions of 30 ppb or more that can immediately respond to the attack of plankton is an advantage.

FIG. 1 is an explanatory diagram showing an implementation method for preventing the invasion of birds that damage the cultured laver. (Example 1) FIG. 2 is an explanatory view showing an implementation method for preventing the invasion of fish that damage the cultured laver. (Example 2) FIG. 3 is an explanatory diagram showing an implementation method that can reduce the number of laver attached bacteria. (Example 3) FIG. 4 is an explanatory diagram showing a plurality of copper electrodes and a titanium platinum plating electrode attached to the cultured ladle net for direct current energization of the cultured laver net for frequent red tide in the deep sea area. Can be removed. (Example 4)

An embodiment for preventing the invasion of birds is that a titanium wire platinum plating electrode is arranged on a rope of a laver net, and the electric power of the solar power generator and the wind power generator is charged to the battery in a polarity switching device. By wiring and supplying power so that the current is always positive through the electrode, the diffusion of hypochlorite generated by electrolysis of natural seawater around the laver net from the titanium wire platinum plating electrode It is possible to prevent food damage by giving a warning signal by using the warning ability.

As described above, fish can also detect a similar warning signal due to the diffusion of hypochlorite, and can be prevented from being damaged by being cautious about the net.

Nori foliar adhering bacteria are sterilized and controlled by the effect of hypochlorous acid generated by the above-mentioned electrolysis.

Similarly, the copper ion has a concentration of 30 ppb or more in seawater by energizing the copper rod when supplying the electric power generated by charging the photovoltaic power generation device and the wind power generation device to the battery via the polarity switching device. Since copper ions are generated, the bactericidal action protects the laver leaf body by eliminating and eliminating the plankton of the laver leaf body such as red tide.

If copper ions are used in shallow water, etc., and there are concerns about the effects of clams on clams, the copper electrode can be recovered on the work boat and reused when the red tide strikes. Since it occurs frequently, it can be used continuously to kill and control plankton such as red tide.
