运输水体添加Vc对鲤鱼运输应激的影响

his study investigated effects of vitamin C added to the water in common carp (Cyprinus carpio L.) under transport stress. The study set up a control group, model group and Vc alleviation groups. After 5 h transportation, plasma and liver samples of fish in the model and Vc alleviation groups were used for determination of hematological parameter, vitamin C and antioxidant-related parameters. In the model group, plasma cortisol and glucose concentrations were significantly increased compared to the control group（P﹤0.05）. While, plasma cortisol and glucose concentrations of alleviation group were significantly lower than in the model group（P﹤0.05）, and no significant differences were found between alleviation and control group（P﹥0.05）. The activities of liver superoxide dismutase (SOD) in the model group were significantly decreased compared to the control and alleviation groups（P﹤0.05）, and activities of liver SOD in alleviation group were also significantly higher than in the control group（P﹤0.05）. The levels of liver malondialdehyde (MDA) were significantly increased in the model group（P﹤0.05）, and no significant differences were found between alleviation and control group（P﹥0.05）. Plasma vitamin C concentrations in the alleviation group were significantly increased compared to the control and model group（P﹤0.05）. Above all, transport stress could cause an adverse effect on the body health in common carp, and vitamin C added to the water may play key roles in the alleviation of transport stress.
