Abstract
Gametogenesis can significantly affect the biochemical composition of oysters, but little research on the difference between sexes. Therefore, we conducted the first in-depth study on the composition differences between males and females of three different Crassostrea sp.. The results showed that females had higher glycogen, lipid, Cu and Zn contents than males, while males had higher protein and taurine contents than females at maturity, which might be related to special meiosis pattern of eggs and less energy was required for female gametogenesis. In addition, both males and females had well-balanced essential amino acid compositions. The omega-3: omega-6 (n-3: n-6) ratio of males was significantly higher than that of females, indicating that the nutritional quality of males was higher. These results provide a reliable and refined theoretical and research basis for revealing the nutritional quality, extracting beneficial ingredients, and developing functional food of Crassostrea sp., and provide data support for the sex-regulated breeding of oysters.
