The shore area along the Hokkaido coast in the Okhotsk Sea have high fish catches and shellfishes live in the ocean bed such as scallops or oysters accounts for 30% among fisheries resources in these area. Abundant primary production and enough nutrients to support production are necessary to maintain resource of benthos which cannot make migration. However the Soya Warm Current flow in these sea area which is the dynamic current of the Tsushima Current originated the Kuroshio Current have a low in nutrients. Therefore it can contribute to the sustainable local fisheries in the Okhotsk area to elucidate nutrients sources of supply to the Soya Current. This study is to development the classification method with four channels at most from MODIS satellite imagery for coastal water around the mouth of the Tokoro River, which is the good inshore fishery spot for scallops, for the purpose of monitoring of the influence range of the river water which would be supposed as one of the nutrient sources of supply to the coastal area of Soya Current. As a result, the transportation of the suspended solids was able to observe about 8.5 km to the northeast direction from the mouth of the Tokoro River in satellite imagery
