複数個を並べて配設している。First, FIG. 1 shows a block board 2 having an appropriate size and thickness installed on the ground of a seabed 1 and a plurality of recesses inside, that is, as shown in FIG.
A block 4 having a height of 0 cm, a width of 10 to 50 cm and a depth of 10 to 50 cm is formed, and a block 4 having a flat upper surface is detachably provided from the block plate 2 by arranging one or more suitable blocks. I have.

能である。The above block 4 has one side,
Or, on both sides of the back-to-back, the above-mentioned hidden space 3 is formed, and the space of the height, width and depth of the frontage as described above is used.
It is preferably formed as a retreat where seafood such as sea urchins, abalones, octopuses, and sea turtles that inhabit the sea floor are protected from external enemies. Of course, the height, width, and depth dimensions can be changed as appropriate.
