Abstract In this study, effects of different temperatures (20 ℃, 25 ℃, and 30 ℃) air exposure (12 h) on the survival rate and biochemical indexes of four shell color stains of Pinctada fucata were studied. The survival rates of P. fucata after 72 h′ re-watering period, and the activities of 11 biochemical indexes of P. fucata were measured. 11 biochemical indexes included as follows: digestive enzymes (lipase (LPS), amylase (AMS) and cellulase (CL)), antioxidant related indicators (superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), anti-superoxide anion free radical (ASAFR), peroxidase (POD), total antioxidant capacity (T-AOC)) and hydrolytic enzymes (acid phosphatase (ACP) and Alkaline phosphatase (ALP)). The results showed that 12 h′ air exposure at 30 ℃ significantly reduced the survival rate of P. fucata (P
