Abstract:In order to explore the effect of environment on the nacre color of shells, we cultured a group of genetically identical oyster Pinctada martensii in four different areas: Li'an in Hainan Province, Liusha in Guangdong Province, Beihai and Fangcheng in Guangxi Province. One year later, the shell colors of P.martensii in the four areas were measured using CSE-1 Imaging and Color-Measuring System, and the Lab values were recorded. The results showed that the oysters cultured in different areas exhibited different shell colors. Specifically, the oysters of Beihai, Fangcheng and Li'an were quite close in shell colors, having higher lightness and green and yellow tone, while the oysters of Liusha showed significant color difference in shells to those of the other three areas, demonstrating relatively lower lightness and green and yellow tone, quite close to white color.
