The state of installation on the seabed may be a state in which squid fish reefs are scattered one by one or an appropriate number of fish reefs are collected.

[0013]

Since the present invention is configured as described above, it has the following effects. 1. In order to apply the spawning habit of squid and make the spawning rate effective, unevenness is formed on the lower surface of the upper plate or natural stone is made to form pits and cracks, and ocean currents and other It is possible to prevent the damage of the eggs and improve the efficiency of stable spawning implantation. 2. By preventing the sun and daylight, it is possible to prevent the adhesion of seaweed, algae, etc., to withstand the ocean current, and to withstand the external enemies of squid and other fish. 3. Base 1A and support 1B planted on this base
Since the basic structure is composed of a plane circular upper board 1C that is connected and supported in parallel with the base at the upper end of this pillar, the structure does not fall or move due to the tide (ocean current). 4. Since it can be lifted by using a hanging hook, it is possible to move structural objects according to changes in the ocean current, and due to the squid's habit, it is possible to increase the catch by spawning migration.
