The habitat of the Manila clam (Ruditapes philippinarum) was assessed using habitat suitability index (HSI) factors considering growth (Chlorophyll a, Hydrodynamics), survival (Sediment-sand, Exposure time) and water- environment (Dissolved oxygen, Salinity). As a result, data layer assessed Manila clam habitat, it was possible to calculate the preferred area. Consequently, it was found that areas which seemed to prefer for Manila clams (HSI > 0.5) covers 1.23 km2 (Weight) out of 5.32 km2 and (HSI < 0.5) covers 4.09 km2 (Weight) out of 5.32 km2. Based on these results, it is estimated that Manila clams preferred habitat can be distinguished in areas other than the Boryeong tidal flat. Additionally, continuous environmental monitoring will have to be carried out for habitat management of tidal flats, and it is expected that these studies will develop habitat-based evaluation methods.
