In order to investigate the possibility of yearly-harvest, we carried out growth experiment (shell height, meat weight and condition index) for of the artificial oyster spat, which suspended in three different times before the season for natural spat around coastal waters of Gyeongnam Province. Shell growth of spats suspended in June showed higher than those in April and May. In meat weight, the growth of spats was significantly elevated from October, of which significant difference was observed depending on growing farms (Gosung<Tongyeong and Koje). Using condition index, we found that the spat deployed in April and May were spawned on August or September, however, could not that in June. The estimated yield time were accounted for September on the shell height level (≥ 80 mm) and October on the meat weight level (≥ 5 g).
