ABSTRACT

Since 1971, artificial reefs of durable concrete structure were constructed and installed as government-subsidized projects for the creation of new fishing grounds in Korean coastal waters. Few reports are available on the reef structure designs suitable for target fish species. Although there have been many reports on the effectiveness of artificial reefs with comparative analysis of effectiveness between artificial reefs and natural reefs or among artificial reefs. Since the reef shape of each unit structure gives a different shadow area, void space and surface area thus attracting different fish species, it is important to select the best structural design, with a limited funding for each site, for optimization of fish habitat according to the target species and environmental factors. In order to establish effective fishing ground environment equipment and artificial reef in coastal area, the methodology to select the optimal site for artificial reef should be applied after analyzing the correlation between fishing ground environment and ocean environment. In this paper, thematic maps were prepared using remote sensing and geographical Information System(GIS) for the physical and geological conditions which are considered as the most elements when selecting optimal site for artificial reef in coastal waters of Korea.

The results showed it makes possible for this methodology, which selects the optimal site for artificial reef using remote sensing and GIS, to manage the institution of artificial reef more entirely and efficiently through analyzing and visualizing.

INTRODUCTION

The recent oceanographic and environmental projects operate usually with large interdisciplinary multi-variable data sets. These data sets have to be quality checked, reliably stored, and analysed. It is necessary to manage large sets of interdisciplinary data of the ocean and coastal environment that can contain a lot of variables from different sources and with different structure (oceanographic, meteorological, biological, etc).
