Brief introduction of oyster

Oysters are also one of the most resistant aquatic animals. In the past 200 million years, the changing environment in intertidal zone has exercised the strong resistance of oysters to temperature, salinity, common pathogens in the open air and sea. When the water comes out at low tide, it can tolerate the hot and dry weather in summer and adapt to the freezing weather in winter successfully, and can survive without water for 1 ~ 2 weeks or even 1 month.

China is rich in oyster resources, which is the hometown of oysters and has a long history of using oysters. As early as more than 2,000 years ago, residents in some areas along the southern coast of China mastered oyster culture technology. At present, there are oyster production bases in Bohai Sea, Yellow Sea, East China Sea and South China Sea, and the main producing areas are Fujian, Guangdong, Shandong, Guangxi, Liaoning and Zhejiang.
