The present invention relates to a net breaker and a method of manufacturing the same, which can more effectively eradicate illegal fishing in waters requiring management and protection, thereby preventing indiscriminate overfishing and desolation of fisheries.

In general, the types of illegal fishing caught in the coastal waters of Korea include acts of unauthorized fishing, illegally modifying or modifying fishing gear, violating the prohibition zones or prohibition periods, and prohibiting capture prohibitions. And catching fry (young meat), and the like.

Such illegal fishing is a serious environmental destructive action that causes unreasonable overfishing and desolation of fisheries. The fisheries guidance agency and marine police under the Ministry of Food, Agriculture, Forestry and Fisheries are frequently cracking down and try to eradicate illegal fishing. Due to limited manpower, time and money, it is difficult to crack down on illegal fishing.

In addition, for the management and protection of fisheries that are very important in terms of environmental and ecological aspects, enactment of non-operational zones or periods of non-operation, and then intensive enforcement of illegal fishing within the range of waters and periods. Even if it is held, the major fishing grounds that need to be managed and protected are gradually devastated by illegal fishing boats that infiltrate the fishing grounds and run off at night.

In particular, in recent years, many Chinese fishing boats have invaded the west sea of our country, and illegal fishing is done in the seas of our country. In addition to the devastation of major fishing grounds, there was a high possibility of becoming sparked by diplomatic friction between Korea and China.

In order to effectively eradicate illegal fishing occurring in major fishing grounds that require management and protection as described above, it is necessary to allow illegal fishing boats to give up fishing itself by making it impossible to operate in the waters rather than the artificial guidance and control that has been carried out. It was determined that it is most desirable to induce, and for this purpose, the mesh breaker according to the present invention has been proposed.
