Abstract: In this study，the growth and survival rates were studied in spat geoduck clam Panopea japonica with shell length of 1.70 mm±0.31 mm（group S）and 5.04mm±0.63mm（group L）exposed to air for 4，8，and 12 h，and recovered in 3，6 and 9 days at temperatures of0，10 and 20℃to evaluate the effects of exposure and desiccation on growth and survival of spat geoduck clam.The results showed that there was significantly stronger tolerance to exposure to air in spats in group S than in group L in same condition（P＜0.05）.In the same duration of desiccation，however，the order of survival rate at different temperatureswas expressed as10℃＞20℃＞0℃.The spats exposed to air at 0℃in group S had lower survival rate when they were revered for 6 days（30.22％± 6.48％）and 9 days（19.78％±7.70％），with significantly different from the other groups（P＜0.05）.There was higher specific growth rate in spats exposed to air in group L than that in the control group in a certain period in suitable condition，which may be involved in compensatory growth.
