수하시기에 따른 참굴 인공종묘의 성장 비교 = Growth Comparison of the Pacific Oyster Spat, Crassostrea gigas, by Three Different Suspended Time Around Coast of Gyeongnam

다국어 초록 (Multilingual Abstract)

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).
