Description

Artificial fishing reef}

The present invention is an artificial structure to help spawning and breeding mollusks such as fish, shellfish and octopus, octopus, which face the problem of depletion of marine resources due to the disappearance of seaweed in coastal rock due to various environmental changes. It is about an outstanding artificial reef.

Natural molluscs live in places such as rock caves and rock shelves. The place is rich in small living things such as shellfish and is protected from pirates and is a good place for spawning. Tens of thousands of eggs are laid on the ceiling during spawning. In order for the eggs to hatch, it is indispensable to keep clean and at the same time supply fresh oxygen-rich seawater. In recent years, the environment of the sea has been greatly changed due to climate warming and various environmental changes, and is facing the problem of depletion of the entire fishery resource due to the tidal sea phenomena where seaweed disappears in coastal rocks. Therefore, the artificial reef facility business is making efforts to increase fishery resources by artificially creating a sea environment by making various artificial structures. In this artificial reef facility business, it is urgently needed to develop functional reefs mainly targeted for certain targets, and molluscs such as high-income octopus and octopus are not farmed, so there is only a way to help spawning and breeding in the natural state.

To this end, conventionally, a ceramic roasting body made of primitive grills, in which a predetermined number of passage holes are formed on one side and an entrance for mollusks on the other, is directly installed on the seabed as a mollusk fish.

The above ceramic cylinder had the following problems.

First, since the structure is a simple cylinder and the installation surface is round and small, stable and solid installation is difficult. In addition, when the seabed is soft ground such as sand, it is gradually buried, and when it is uneven ground, it is unstable and unstable, and when it is inclined surface, it rolls down, and because of being light, it moves under the influence of algae or waves. In addition, the doorway may be present near the seabed, and may be filled with relatively small rocks or the like.

Secondly, molluscs have a habit of moving the seabed, and the entrance is multi-directional, thereby increasing the chance of entering the entrance, but there is a problem that the entrance and exit of the body is only one direction.

Third, when several cylinders are installed adjacent to each other, the area of octopus collides, and there is a fear that only one octopus may settle, and when the entrances are adjacent to each other or are arranged to face each other, an area dispute occurs strongly. It is very difficult to efficiently arrange a plurality of cylinders using the sea floor effectively.

Fourth, it is difficult for the eggs laid on the ceiling inside the body to hatch smoothly. One reason for this is that fresh seawater may not be sufficiently supplied into the tubular body even when molluscs spew seawater into the eggs from the tubular body. Fresh seawater flows inside the cylinder when the direction of seawater flow is close to the water passage hole and the entrance. However, when the flow is sideways, the seawater inside the body is collected. On the other hand, when tidal currents and waves are affected by the terrain, and when the cylinder rolls and the ceiling and the floor are turned upside down, countless eggs stuck to the ceiling pile up and become dirty, become unsanitary, and fresh seawater cannot enter. It becomes difficult to hatch.

Fifth, there are many enemies in the young men who hatch and enter into the floating period, and when the enemy invades from the entrance, there is no place to hide even if you escape from the water hole, so it becomes the food of the enemy.

The present invention has a problem in solving the above problems.

The present invention

A plurality of horizontal through-line flow paths are formed in the bottom lattice of the concrete hexahedral lattice structure having a trapezoidal cross section as a refuge for settlement fish, shellfish and mollusks,

On the upper surface of the ceiling lattices of the concrete hexahedral lattice structure having a trapezoidal cross section, a thick portion of the trapezoidal cross section is formed to increase the attachment area of the seaweed,

The upper surface of the thick portion was roughened to help to firmly attach the initial attachment and rooting of the seaweed, thereby solving the above problems.

The artificial reefs of the present invention have a structure in which each standing surface and the ceiling surface are open, to prevent overturning and loss due to the waves, and the thick portion of the trapezoidal cross section on the ceiling surface makes a larger area, increase the adhesion area and, in the surface of the cloth forward surface rough, firmly the initial adhesion and the roots down the seaweed, and by making a variety of shaped holes of the grid framework fixability fish, shellfish or molluscs in an octopus, etc. of the form, Help with stealth, spawning, etc.

In terms of the characteristics of fish, there are types of fish that live in contact with all or part of the fish's body. Representative fish species such as rat snail, sea bream, and fish roe are mostly coastal settled fishes, which contribute to increasing fish disinfection. It is an expensive fish species that occupies. The artificial reefs of the present invention can help the habitat, spawning, stealth, etc. of these species.

In addition, the artificial reef of the present invention is a variety of escapeable caves are formed, it is possible to provide a good environmental conditions for the spawning, habitat, stealth of mollusk octopus.
