In order to improve oyster farming condition, estimation of food availability (CC) was carried out in Garorim Bay, Seosan, Korea. The primary production of the waters were ranged from 0.07 to 0.26 gC/m2/day. A strong tendency was observed that the inner side of the bay was higher at primary production. Estimated food availability was ranged from 0.0424 to 1.655. Temporal shortage in food supply was observed at April with about 15% less than the oysters’ requirement, which may be causative of spat mortality after introducing into the farms. Food availability was met the food demand during summer but significant shortage was also observed at after August, which may main causative of retarded oyster fattening in the waters. This study suggested that adjustment of cultural density may be necessary for the improved harvesting of the oyster.
