DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squid spawning reef covering block, which is suitable for the following matters. 1. Marine structures such as coastal conservation facilities, harbor facilities, and fishing port facilities. 2. Of the above facilities, quays and harbors such as berths and fishing harbor facilities are kept calm, and breakwaters that block waves so that ships can anchor safely, and seawalls that protect the land from waves. 3. Of the above breakwaters and seawalls, the main body work is installed stably,
A covering block that protects the basic rubble from waves to disperse the weight of the main body work on the sea floor. 4. By adding a function of spawning squid to the coated block, it contributes to an increase in squid resources.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. 1. There is no spawning function added to the blocks covering the basic rubble. 2. Heretofore, there has been an egg-laying block only for the purpose of expanding fishery resources. 3. The block has a ceiling as a fish reef so that marine products can be spawned, and has a structure in which the block is installed on the seabed with about 3 to 4 feet.

[0003]

The above-mentioned prior art has the following problems. 1. There is no function to protect the basic rubble from the waves because of the spawning block as a fish reef. 2. In many cases, it is installed as a fish reef block on the seabed alone, and can easily be buried due to the movement of the seabed sediment and lose its function. 3. Since the area subjected to the upward pressure due to the waves is large, it lacks in wave resistance stability, and may fall down during high waves to lose its function. 4. Since the block is installed alone, there is little effect of collecting squid. The present application has been made in view of such problems of the related art, and has as its object to provide the following. 1. The block of the present invention is a structure having a bottom surface for protecting the basic rubble from waves. 2. By providing a shelf on the block, the squid can easily lay eggs. 3. The height and depth of the shelves are determined to be the most suitable for spawning based on research on natural squid spawning reefs. 4. The thickness of the block can be varied according to the strength of the waves, and the number of shelves for laying eggs can be increased to two. 5. A hole leading to the top of the block is provided at the back of the shelf to supply sufficient oxygen to the laid egg mass and to wash away dust and the like attached to the egg mass by the flow. The shape of the hole may be circular or rectangular. 6. By using as a part of structures such as breakwaters and seawalls, if there is movement of bottom sediment on the sea floor, blocks are also installed on the shoulders of the foundation rubble mound to minimize the effect of movement of bottom sediment be able to. 7. The above structure acts as a simulated reef in the ocean for aquatic products, and has a fish collecting effect. For this reason, it is expected that the squid resources will be proliferated.
