Abstract: In order to study the effect of typhoon on the cultured Portunus trituberculatus, the changes of T-SOD, CAT, MDA, GSH, ACP and Na+, K+-ATPase in the hearts, gills and hepatopancreas were detected in 12 hours before and after typhoon “Canhong”(1509) at Xiangshan in July, 2015. The typhoon increased highly significantly the activity of the T-SOD enzyme (p<0.01) and increased significantly CAT enzyme(p<0.05) in the gills. After typhoon, the MDA and GSH content in gills increased insignificantly (p>0.05). T-SOD enzyme activity in the hepatopancreas showed an insignificant trend of decrease (p>0.05) while the CAT enzyme activity showed an insignificant trend of increase (p>0.05), MDA content increased significantly (p<0.05) and the increase of the GSH content was highly significant (p<0.01). In the hearts, the levels of T-SOD, CAT enzyme activity and GSH content increased and the MDA content decreased, but these changes were not significant(p>0.05). In addition, the ACP enzyme activity in the gills and the hearts increased insignificantly(p>0.05), which was reduced but not significantly in the hepatopancreas (p>0.05). The Na+, K+-ATPase activity in the gills decreased highly significantly (p<0.01), but increased highly significantly in the hepatopancreas (p<0.01) and significantly in the heart (p<0.05) . This study reveals that the typhoon can cause the cultured P. trituberculatus stress response in the short term and solutions are need to take to avoid typhoon damage to cultured P. trituberculatus.
