Oysters are produced by Li Du and are called "oysters" in South Guangdong. Oyster meat is tender and smooth, rich in nutrition, and has the reputation of "deep-sea milk", which contains colorful protein. Every 100g oyster, excluding the shell weight, contains 87. 1% water and 7 1.2mg zinc, which is rich in protein zinc. It is a good food for supplementing zinc. You can often eat oysters or protein zinc to supplement zinc. Sexual taste: salty; Slightly cold.

In terms of nutrition and delicacy, steamed oysters are much more delicious than boiled oysters, unless you want to make soup with them. Because in the process of cooking, the soup, nutrients and umami substances in the body are easily lost to the water, so the cooked oysters are not delicious, and the umami and nutrition are also lost.

Living habits

The hard area of the seabed where the pleated oyster lives is called oyster bed, which is located in deep or shallow seawater or salty estuary waters. Pleated oysters live in the middle of intertidal zone.

Concha plicata fixes shellfish. Generally, it is fixed on shallow sea objects or seaside rocks, and eats and breathes by opening and closing shells. As filter-feeding organisms, they mainly feed on micro zooplankton, diatoms and organic debris.

Oysters generate airflow in water by vibrating cilia on gills, and water enters gills. Suspended particles in water are stuck by mucus, and cilia and tentacles on gills classify particles according to their size. Then the small particles are sent to the mouth, and the large particles are transported to the edge of the film and thrown out.
