Description

Steel artificial reefs with the avoiding system for entangling of fish nets}

The present invention relates to artificial reefs installed on the seabed for the creation of fisheries resources, and more particularly, to a fishing net reduction type forced reefs constructed so that fishing nets are not caught by steel reefs.

Forced reefs were first installed in Pohang, Gyeongbuk, in November 1988 by Pohang Iron & Steel Co., Ltd., and research has been focused on forced reefs since the late 1990s. Techniques for these findings are described in detail in the following publications. The technology includes Korean Utility Model Registration No. 217502 (Force Reef for Fish and Shellfish Formation), Utility Model Registration No. 227407 (Forced Reef with Easily Attached Plate), Utility Model Registration No. 200540 (without welding work) Forced reefs simply assembled with bolt nuts), Utility Model Registration No. 186609 (Force Reef for Deep Sea), Utility Model Registration No. 178474 (Force Reef for Deep Sea), Utility Model Registration No. 176858 (Force Reef for Soft Ground) and Utility Model Registration No. 170791 (Forced ground for soft ground).

Description of the above-mentioned forcing reefs, "Facilities for deep seas" in Utility Model Registration No. 186609, "Force reefs for deep seas" in Utility Model Registration No. 178474, and "Force reefs for soft ground" in Utility Model Registration No. 170791 The structural stability and the fisheries resource creation effect of mandatory reefs have been recognized by the Ministry of Oceans and Fisheries and have been used as general reefs since March 2001.

Figure 1 shows the type of reefs according to the prior art, (a) of Figure 1 is a rectangular concrete reef, (b) is a box-shaped large forced reef, (c) is a two-stage box-shaped large reefs, respectively. The fish shown in Figure 1 is usually the most commonly used form of fish, is configured to achieve an angle in the production environment of the fish. In particular, the upper edge of the square fish is configured to have a sharp angle, it provides a function to prevent the overfishing and depletion of the fishery resources by catching the fishing net during illegal or random low-fish net fishing (net fishing).

While these prismatic reefs have a function to prevent overfishing and depletion of fisheries, torn fish caught in the reefs are often left in the reefs, in which case the fish caught in the reefs die and the fish caught in the net dies. There is a problem of polluting. Therefore, it is impossible to achieve a role as a habitat, a breathing place (resting ground), etc., which are the basic purposes of the fishery, and thus the waste fishing nets caught on the fishery should be removed. As a result, a large amount of effort is required for the post-management of fish reefs, such as high costs for removing the fishing nets, resulting in economic losses. In particular, when the fish net is installed in a deep water is caught, it is necessary to submerged to remove the waste fishing net, more problems occur.

Accordingly, the present invention has been made in order to solve the problems of the prior art as described above, by applying a triangular pyramidal and triangular prismatic components to the existing various kinds of reefs fishing net reduction to reduce fishing nets The purpose is to provide forced reefs.
