In general, in artificial cultivation of abalone, sea urchin, etc.
After artificially incubating abalone and sea urchin eggs until they become young,
Although they were released into natural fishing grounds, the catch yield of adult shellfish was poor due to their dispersion. In order to improve this fishing yield, artificial aquaculture is being carried out, albeit on a small scale, in which young abalone and sea urchin are raised until they become adult shellfish by periodically introducing kelp, etc., as bait into cage-like containers. Facilities have been implemented in recent years.
しかし、上記従来の人工養殖設備においては、

According to the above configuration, when direct current is passed continuously or intermittently between the cathode member and the anode member,
Ions in the seawater turn into inorganic compounds and are deposited on the surface of the metal mesh of the cathode member to form an electrodeposition layer, and seaweed spores adhere to and propagate on the electrodeposition layer, resulting in an artificial algae reef. Further, the anode member becomes an acidic atmosphere due to electrolysis, so that marine organisms do not stick to it.

１の高さは10cm〜1mに設定されている。 The artificial aquaculture facility 1 for abalone, sea urchin, etc. includes a cathode member 3, a support member 4, an insulating material 5, and an anode member 2. The cathode member 3 is a semi-cylindrical square with a side of 1 to 10 m and a height of 10 cm to 1 m, and is made of a wire mesh with a mesh of 1 to 10 cm made of a conductive material, such as steel wire, installed in the sea, for example, on the seabed 13. It's summery.
The strut material 4 is cast into the soil of the seabed 13.
The insulating material 5 is attached to the support member 4 and fixes the anode member 2. The anode member 2 consists of net-like fences 11 made of a conductive material, such as carbon fiber, fixed to the seabed 13 at regular intervals around the cathode member 3. The mesh size of the fence 11 is 20 mm or less, based on the size of young shellfish such as abalone and sea urchin 18.
The height of 1 is set between 10cm and 1m.

The cathode member 3 and the anode member 2 are connected to the cathode and the anode, respectively, by a current-carrying cable 8. In addition, the DC power supply 9 connects the electric wire 1 to a general household outlet.
Connected by 0.
つぎに、本考案の実施例の作用を説明する。 Next, the operation of the embodiment of the present invention will be explained.
陰極部材３と陽極部材２との間に直流電源９か

ビ、ウニ等１８を容易に養殖することができる。 When a DC current is passed continuously or intermittently from the DC power source 9 between the cathode member 3 and the anode member 2, electrolysis occurs through the seawater, and ions in the seawater become inorganic compounds, such as those with low solubility in seawater. Low calcium carbonate becomes magnesium hydroxide and becomes cathode member 3
An electrodeposited layer is formed on the surface of the wire mesh 14 forming the electrodeposited layer. This electrodeposited layer becomes a base for the seaweed 16 to settle on, and seaweed spores adhere to and propagate on the base to grow the seaweed 16. As a result, seaweed 16 that becomes food for abalone, sea urchin, etc. 18 can be obtained artificially, and abalone, sea urchin, etc. 18 can be easily cultivated.

デのような害敵が進入することもない。 On the other hand, the surface of the anode member 2 becomes an acidic atmosphere due to, for example, chlorine due to the electrolysis of seawater, so that marine organisms do not adhere to and collect on the anode member 2. Therefore, abalone, sea urchin, etc. 18 will not climb up the anode member 2 and be dispersed to the outside, and harmful enemies such as starfish will not enter from the outside.
直流電源９から供給する直流の電流密度は通常
１〜6A／m2の範囲が可能であり、特に３〜4A／
