A very weak direct current generated in the solar cell 7 during the daytime flows from the anode surrounding structure 3 on the anode side to the cathode structure 5 on the cathode side via the seawater. The electrode battery that was the cause of the corrosion formed on the surface of the wire mesh 13, which is the base material of the metal mesh 13, disappears, and the corrosion current stops flowing. Therefore, the wire mesh 13 is cathodic-protected (externally powered), and at the same time, the surface of the bare steel wire of the wire mesh 13 is coated with a highly dense and corrosion-resistant seawater-resistant material containing calcium and magnesium in seawater as its main components. Large trace amounts of mineral matter are slowly accumulated.

That is, except at night when solar energy is not available, a good corrosion-resistant coating is formed on the bare steel wires of the wire mesh 13 in a state where the corrosive action of seawater is kept to a minimum. If a power storage device (not shown) is added to store excess photovoltaic power from the solar cell 7, the anticorrosion and film forming effects can be continued throughout the day and night.

In this way, depending on the installation location of the fish tank 6, after about one year, for example, a 1.5 mm thick anti-corrosion coating will be formed on the 3 mm diameter bare steel wire forming a 5 mm square mesh. Compared to the 2-3 year life expectancy of wire mesh when adding cathodic protection to the conventional galvanizing method, it is expected to have a long service life of approximately 10 years or more.

In addition, since the wire mesh 13 is submerged below the anode surrounding structure 3, which has an upper width that sufficiently covers the splash zone and tidal zone of the sea surface, it can be avoided from being hit by or damaged by driftwood, etc. Even if the anticorrosion coating is damaged by some external force, the damaged portion can be easily repaired by forming a new coating by applying electricity. Furthermore, since the wire mesh 13 collects alkaline ions such as calcium and magnesium, which are well-accepted by living things, an artificial fish farm suitable for raising yellowtail, yellowtail, etc. can be obtained.

On the other hand, when the anode surrounding structure 3 is energized by the solar cell 7, its surface becomes an acidic atmosphere and generates chlorine gas, etc., so that marine organisms do not adhere to the surface of the anode surrounding structure 3. The fish tank 6 is always kept in a good environmental condition without clogging. Furthermore, since the anode surrounding structure 3 is made of carbon fiber, it has extremely high corrosion resistance against seawater. exposed above.

According to this embodiment, since an anode current flows through the main body of the fish cage, it is possible to prevent seaweed from attaching to the whole fish tank, and it is possible to prevent the fish cage from being replaced regularly as in the conventional method.
The work of cleaning adherent seaweed can be greatly reduced.
