説明

We collected and examined the data of artificial reefs （ARs） that Korea and Japan have developed. ARs projects in Korea have practically started in 1971 under the governmental supervision. As a result, fish catch and income for fishermen appeared to be fairly improved. Recently, however, seaweed reefs are often being installed in shallow coastal areas to create sea afforestation as one of countermeasures of Isoyake. On the other hand, in Japan ARs have been developed and utilized in the earlier times than in Korea. However, ARs installation has just become a national project since 1951. In particular, recently ARs projects have been integrated to be fisheries-based maintenance projects so that Japan could establish a consistent management system for fisheries. On the other hand, ARs used in Korea and Japan did not indicate a big difference in their shape, size, material and weight for a single unit of reef, but they revealed a significant difference in the classification of ARs. In addition, the requirements for ARs were nearly equivalent with each other in their physical, ecological, and economic functions. However, it is essential to secure substantial evidence to evaluate the functions of ARs, such as economic efficiency, safety and stability.
