摘要： To explore the effect of three selective generations of mirror carp, Cyprinus carpio L., resistant to Cyprinid herpesvirus 3 (CyHV-3), the mirror carp were infected with the virus, and differences of survival rate and immunity among generations were evaluated. These results demonstrated that there were significant survival rate differences between G1 and the other two generations, which implied that G2 has similar genetic resistance ability with G3. Acid phosphatase (ACP) in the spleen, glutathione (GSH) and total antioxidation capacity (T-AOC) in the kidney, lysozyme (LZM) and immunoglobulin M (IgM) in the serum, and alkaline phosphatase (AKP) in the spleen and kidney also showed significant differences between G1 and G3 or G1 and G2/G3, while complement 3 (C3), C4, and superoxide dismutase showed no significant difference between G1 and G3. These results indicated that ACP, AKP, GSH, T-AOC, LZM, and IgM were activated in response to infection of CyHV-3 and helped to protect fish from virus damage. The increasing trends were concordant with the survival rate among the three generations except for the decline in the ACP activity. Therefore, these could be indicators for resistance of common carp to CyHV-3, especially for AKP. The agreement of the significance between survival rate and immunity illustrates that G3 possesses strong resistance ability to CyHV-3 virus and has little or no potency for further selective breeding.
