Description

Artificial fish shelter with fishway function

The present invention relates to an artificial reef, and more specifically, it extends as much as a required length in the longitudinal direction, and a fishing boat is formed therein, which can be used as a moving path for small fish. Since it is put in, it relates to an artificial reef that has a fishing function that is easy to install.

Artificial reefs are artificial structures that are installed underwater to protect and nurture fishery resources, for example, by providing hideouts or habitats to fish, causing seaweeds to attach and breed, and abalone or hermits that feed on seaweeds. To make.

There are various types of artificial reefs, including those made of concrete. However, artificial reefs made of concrete are too heavy, and, for example, when they are put into the sea, the sedimentation speed is fast, so they often get stuck in the bottom of the seabed and cannot function properly as artificial reefs. In particular, concrete itself is eroded by seawater As it generates harmful substances, it gradually cracks.

In order to solve the problems of the concrete type artificial reef, artificial reefs using a method such as iron plate and pipe have been developed. For example, a plurality of beams are welded to form a cuboid, and then welded again to form a structure of a desired shape. However, this type of artificial reef takes a long time to produce and is expensive to produce. Moreover, because of its large size, it is often difficult to move the finished artificial reef to the dropping point. This is because the number of artificial reefs that can be loaded on a ship is limited.

On the other hand, in order to solve various problems of the conventional artificial reef as described above, the artificial reef and its manufacturing method (Domestic Registration No. 10-0773521) have been proposed by the inventor of the present application. The proposed artificial reef takes the form of extending in the longitudinal direction and has the characteristics of being easy to install and stable due to its low center of gravity, since it is dropped onto the sea at the same time as being manufactured on board.

However, the above-described artificial reef has the disadvantage that the body has an open structure and thus the functionality as a hiding place for small fish is poor. This is because although the frame is formed, the inner space of the body bent in the shape of the letter L is open to the upper side or the side, so that even large meat can enter and exit. In addition, it was not heavy, so it could be swept away by the algae while it was located on the sea floor.

In addition, an upper passage 26a is provided between each first flat portion 21. The upper passage 26a is a passage between neighboring first planar portions 21, and opens the first space portion 25a upwards to allow fish to enter and exit the first space portion 25a. The width w of the upper passage 26a may be varied as needed, and may be the same as the diameter of the through hole 24.

The inclined surface portion 23 is integral with both ends of the first plane portion 21 in the longitudinal direction (the length direction of the artificial reef), and is a portion bent to have an acute angle between the first plane portion 21. The angle θ of the inclined surface portion 23 with respect to the first flat portion 21 may be varied as necessary, and may be, for example, in the range of 45 degrees to 80 degrees.

The inclined surface portion 23 serves as a partition plate partitioning the first space portion 25a and the second space portion 25b.

The second flat portion 22 is a flat square portion of the same width as the first flat portion 21, and is integral with the lower end portion of the inclined surface portion 23. The angle between the inclined surface portion 23 and the second flat portion 22 may range from 45 degrees to 80 degrees.

In addition, the second flat portion 22 is also spaced apart from each other to provide a lower passage 26b. The lower passage 26b is a passage between neighboring second planar portions 22, and the interval is the same as the upper passage 26a. The lower passage 26b is a passage that opens the second space portion 25b downward.

The first flat portion 21 functions as a ceiling of the second space portion 25b, and the second flat portion 22 serves as a bottom plate of the first space portion 25a.
