Juvenile Japanese scallop Patinopecten yessoensis with shell height of 831.7μm,3.2 mm and26.7 mm were placed in a 60 Lfoam box at a rate of 100 individuals at temperature(10-17℃,15-17℃and 20 ℃)regulated by ice bag to investigate the effects of temperature and sizes on the survival of the Japanese scallop exposed to air.The results showed that low temperature led to enhance the survival rates under the same conditions,with the descending order as 10℃15℃20℃.The best tolerance ability to dry exposure was observed in the scallop with shell height of 831.7μm,with the maximal survival rate.There was no significant difference in survival rates in juvenile scallop with shell height of 3.2 mm and26.7 mm exposed to 15℃and 10℃.After 20 hexposure,however,the juvenile scallop with shell height of 3.2 mm showed significant higher survival rate than the large-size ones(shell height 26.7 mm)did.The findings are practically useful to the transport plan for different size of juvenile Japanese scallop.
