Sinonovacula constricta is a bivalve mollusks in the tidal mud of the Ariake Sea. They had been abated dramatically due to deterioration of environmental condition of the Ariake Sea. They have been activating their important functions to preserve the environmental condition and function as a variable fishery resource. In recent years, these bivalves have been declined. The Ariake Sea has been stocked actively with juvenile shells. In order to stock them rationally, a suitable habitat should be re-created and preserved in the tidal mud environment. This research focuses on the evaluation of the suitable mud condition of bivalves by investigating their living habitat from geotechnical point of view.
