초록
범게의 zoea 및 megalopa기 유생에 있어 수온의 영향을 파악하기 위하여 수온변화에 따른 이들의 생존, 성장 및 탈피주기를 조사하였다. Zoea 및 megalopa기 유생에서 실온과 20℃에서 82.5%와 80%로 높은 생존율을 나타내었다. 성장률은 수온이 높을수록 양호한 경향을 나타내어 30℃에서 zoea 및 megalopa기 유생의 성장률은 각각 185.0% 및 41.6%를 나타내어 15℃구간의 101.6% 및 23.7%에 비해 유의한 성장 증가를 나타내었다. 탈피주기는 온도에 반비례하여 수온이 높을수록 빨라지는 경향을 나타내어, 30℃ 설정 실험구에서 zoea 및 megalopa기 유생에서 각각 16.4일 및 9.2일을 나타내어 15℃의 24.4일 및 15.2일과 비교하여 유의적 차이를 나타내었다.
Abstract
In the present study, the effect of different water temperature (15, 20, 25, 30℃ and ambient) on survival, growth rate and intermolt period of zoeal and megalopal stage of tiger crab, Orithyia sinica were examined. The survival rate of zoeal and megalopal stages of experimental crab was observed high at 20℃ and ambient water temperature. The growth rate of crab larvae showed temperature-dependent increase. Therefore, the maximum growth rate was recorded at 30℃ temperature-regulated group in both zoeal and megalopal stage. However, temperature-dependent decrease in larval stages of crab during intermolt period has been observed in the present investigation.
