Sex-changing patterns of Akoya pearl oyster (Pinctada fucata)

摘要

BackgroundPearl production by transplantation in Akoya pearl oyster >(Pinctada fucata>) is a biotechnology developed in Japan that skillfully utilizes the pearl-forming ability of oysters. In this method, cultured pearls are formed from a pearl nucleus and a small piece of mantle transplanted into the gonads of recipient pearl oysters. In this study, we hypothesized that the sex of the recipient pearl oyster might affect the quality of pearl produced. While some previous studies have examined the sex of Akoya pearl oyster, detailed information is lacking.
