 Abstract
This study was performed to determine the effect of water temperature condition on survival rate and growth of juvenile geoduck (Panopea japonica). Panopea japonica juveniles were bred for 6 weeks at 12, 15, 18, 21, 24 and on incubator. Juveniles median lethal times (LT50) were 29 hours in , 14.5 day in , 37.4 day in . Survival rate of water temperature 12, 15 and showed a high survival rate in 95.0%, 95.0% and 93.3% at 6 weeks. As a result of culturing for 6 weeks at 12, 15, 18, 21 and , a daily growth of shell length and total weight was 0.10 mm, 0.12 mm, 0.13 mm, 0.16 mm and 0.14 mm, and 2.21 mg, 2.65 mg, 2.84 mg, 3.13 mg and 2.93 mg. Juvenile shell length and total weight have significantly increased at . However, mortality rate has significantly increased at more than . As a result, appropriate water temperature for juveniles culturing considered .
