Abstract

Study on environmental change and peculiarity of the Ariake Sea, Japan H. Araki\ K. Sato^, K. Koga\ H. Yamanishi*, K. Ohgushi^ & W. Liengcharernsit^ ^Institute of Lowland Technology, Saga University, Japan *Saga University, Japan ^Kasetsart University, Thailand Abstract The Ariake Sea of Japan is a typical water body surrounded by lowlands, where the area of tidal flats accounts for 40% of all those in Japan and both the tidal flat and the sea have high fishery production. In recent decades, there have been progressive developments such as new harbor, land reclamation and enclosure of a bay. Recent fishery production is abruptly decreasing to a life-and-death problem for fishermen. Many concerned people think that the Ariake Sea is dying through the pollution or change of tidal current caused by such marine works, however an integrated research has not yet been carried out. It is a keen issue to scientifically clarify the characteristics and environmental change of this sea.
