Abstract
Akkeshi Lake is located in Hokkaido, the northern island of Japan. The lake is connected to Akkeshi Bay, which is a part of North Pacific (Figs 1 and 2). The average depth of the lake is 2 m. (1999) formulated an ecological-physical coupled model and has explained the role of eel

grass in the marine ecosystem. The major current that influence the lake is mainly caused by M2 tide and also wind driven circulation (Oshima et al., 1999). There are three main rivers that are connected to the lake and their average nutrient load values are given in Tables 1 and 2. The oyster and clam cultures are carried out in the lake, and it has been earlier observed that epiphytes as well as cultured clam play important role in the material flow of the lake. The purpose of the present work is to reveal the role of epiphyte and clam in the lake ecosystem using three-dimensional ecological physical coupled model.
