The present invention relates to aquaculture reefs for fish and shellfish such as fish, abalone, conch, sea, and more specifically, to provide a protective device in the outer peripheral portion and leg portion of the cultured fish reef to prevent the invasion of predators and at the same time a wood unit having a rest area The present invention relates to aquaculture shellfish for fish and shellfish, which is easily and efficiently arranged and placed in a proper place for abundance of fish and shellfish.

Since ancient times, abalone, a type of shellfish, has used its flesh for food and its shell has been used as a herb and decoration. These abalones are distributed in the clear waters of the coast where the seawater is clear and clean, and the seaweeds are abundant.

However, since the amount of abalone harvested by the diving operation is not large, it is difficult to meet the supply amount according to the abalone demand, so the price of abalone naturally increases, and as a result, many people do not share abalone. In addition to the above abalone, fish and sea cucumber, as well as fish and shellfish research for aquaculture such as seashells are continuously conducted.

Therefore, in order to solve these problems, recently, fish and shellfish other than abalone have been mass-produced in a similar tank artificially or by dropping structures such as fishes on the seabed and farming by discharging fry or chipping.

For reference, the above-mentioned abalone or other herbivorous shellfish such as seashells, as well as echinoderms such as sea urchins, are nocturnal shellfish that feed on algae or diatoms, and on a relatively flat surface (rocks, gravel fields, sand fields, etc.) at night. During the activity, they eat algae and diatoms, and during the day, they have a habit of resting or concealing in the uneven or curved surface of the rock.

As described above, various types of fish and shellfish structures (artificial reefs) for artificially farming shellfish such as abalones of the prior art have been proposed. . The first application is provided with a main member on the outside of the main member, a management passage having an opening and closing door is formed at the center of the main member, and spaces between the main members except for the management passage are divided into a plurality of vertical and horizontal partition members at predetermined intervals.
