外文摘要：The effect of air exposure on antioxidant activities in Pacific white shrimp Litopenaeus vannamei was studied. The behavioral changes in the shrimp and the levels of superoxide dismutase (SOD), malondialdehyde (MDA), and total antioxidant competence (T-AOC) in the muscles and hepatopancreas were determined after the shrimp were exposed to air and then resubmersed in water. Results showed that the duration of air exposure significantly influenced shrimp survival. The maximum air exposure period during which the shrimp could remain alive was 30 min. After 10 min of air exposure, the shrimp could survive when they were resubmersed in water. The T-AOC in the hepatopancreas and muscles was significantly decreased in shrimp that were exposed to air for 20 min. The MDA content in the hepatopancreas was significantly higher for the 20-, 30-, and 40-min air exposure groups than for the control group. During the resubmersion period, the MDA content in the shrimp hepatopancreas and muscles increased. For shrimp that were exposed to air for 10 min, SOD activities in the hepatopancreas and muscles were restored after 3 h of resubmersion in water. Our results indicate that air exposure can cause oxidative damage to Pacific white shrimp, but the damage can be reversed after the shrimp are resubmersed.
