海域の再生化は緊急課題となっている。(Prior Art) Various artificial fish reefs have been proposed in the past, but the proposals for blocks for the cultivation of seaweeds and the establishment of rockworms have not been proposed yet. Edible seaweeds, black sea bream, seagrass, and other seaweeds do not grow anywhere in the rocks in the sea, and rocks with good seagrass vitality are naturally selected and naturally grown. Therefore, in the area occupied by weeds, edible seaweeds increasingly invade their breeding areas, and eventually become only weeds. Destroying this weed by underwater work is a great deal of labor and expense, and if this situation is left unchecked, the depletion of marine resources will be further increased, and for coastal fisheries, the regeneration of this coastal area will be promoted. Has become an urgent task.

用面にも波及するものである。The aquaculture block a thus formed has a water depth of 1
It is submerged on the sea floor of m to 1.5 m, and when seaweeds such as seaweed, black sea bream, and sea lions grow on the part of andesite 5, it grows up to its surroundings, and weeds on the rocks are crushed and exhausted by the block a and gradually eaten. The seaweeds will recover their power and gradually regenerate the coast into fruitful ones. The grown seaweed is picked up by pulling the block a onto a ship, and the weeds attached to the surroundings are scraped off and cleaned, and the weeds are submerged again to be collected until the next collection. Next, the use state of the aquatic aquaculture block a'of the second invention will be explained. The place where the block a'is also submerged is at a depth of 1 to 1.5 m in the sea, and the andesite 5 part is edible seaweed. As in the above, the power of the octopus spreads to the surroundings to drive out the weeds, and the space 6 at the bottom of the depression 3 secures a space that serves as an appropriate approach path in the space around the octopus. In the same way as above, the aquaculture block a ″ of the third invention breeds edible seagrass in the andesite 5, and forms on the circumferential surface of the sand 9 stored at the bottom of the depression 3 as a residence. By properly selecting the passage of the space 6 to be used (passage such as an octopus that cannot enter), it is possible to expect the growth of rockworms.In this case, the sand 9 is stored in a bag made of an appropriate material. Do not damage the rockworm if it is stored in the depression 3. In addition to edible seagrass, seagrass such as arame, which is preferred by abalone, can be settled on the seagrass-adhesive molded body, as well as when artificially cultivating edible seaweed. It is conceivable that if the cells are planted in the binding material 7 containing montmorillonite, the survival of the cells will be accelerated.Of course, this invention can be used for various wave-dissipating blocks, and in the sea in the seaweed growth area, It will also spread to the utilization side such as stacking at a required interval for use.

沿岸海域を活性化する効果がある。(Effect of the invention) According to this invention, not only the fishery resources are positively secured,
It has the effect of activating coastal waters.
