Big Oyster

Big Oyster

　　Scientifically known as Crassostrea rivularis, it is a type of bivalve mollusk that lives in seawater and is commonly found in shallow bays where freshwater flows in. The meat of the big oyster can be eaten fresh or processed into dried oysters (ha chi) and oyster sauce. The oyster meat is delicious and is often referred to as the "milk of the sea." Oyster sauce is a premium condiment. Not only is the oyster meat a tasty delicacy, but it also has medicinal uses, and the shells can be burned to ash or ground into powder, serving as an excellent fertilizer for acidic paddy fields. They can also be used as raw materials for cement and calcium carbide production, as well as additives in livestock and poultry feed. Big oysters are not only widely sold in the domestic market but are also an important export aquatic product. In recent years, large quantities of oyster meat, dried oysters, and oyster sauce have been continuously transported to Shenzhen and Zhuhai, or transited through these special economic zones to Hong Kong, Macau, and other regions.
