Survival, retention rate and immunity of the black shell colored stocks of pearl oyster Pinctada fucata martensii after grafting operation

We have developed a black shell colored selected line observed to have higher survival ability. In this study, to understand its immune capacity, total carotenoid content (TCC) of the black shell colored line (BG) and the control group (CG) were compared. Survival and retention rates, immunity and antioxidant capacity of BG were compared relative to CG at different times after grafting operation. The results showed that BG had significantly...
