Its shell is secreted by the underlying mantle, which extends from the top of the shell to the ventral margin and is composed of two layers of epithelial cells.

There is connective tissue in between.

The membrane is formed, and there are muscle fibers within the membrane.

To make it attach to the inner surface of the shell, the edge of the mantle is thickened to form three folds, and the inner fold has radiating muscles and annular muscles to make the edges close to the shell.

and the subtidal zone with a water depth of no more than 10 meters. [3]

Resistance. Oysters are also one of the most resistant aquatic animals, 200 million years of intertidal environment has trained oysters to temperature, salinity, open space and common pathogens in the sea area, when the tide is exposed, can tolerate the hot and dry weather in summer, but also can successfully adapt to the freezing weather in winter, can survive in the open water conditions for 1 2 weeks, or even 1 month.

In the 90s of the last century, the water quality of the industrial and domestic sewage discharge along the Pearl River declined, which in turn affected the water quality of the oyster farming area, and the oyster farming industry in the manhole was devastated. But after years of improvement, the quality of the manhole oysters is still very good.

4. Rushan oysters.

Rushan City is located at the southeast end of the Shandong Peninsula, with a coastline of 199 kilometers, with 500,000 acres of national first-class seawater quality standard aquaculture sea area, the Huanglei River and Rushan River two major rivers into the sea provide rich nutrients for the sea area, and promote the reproduction and growth of marine basic organisms required for the growth of oysters. Thanks to the unique sea conditions and climatic environment, Rushan oysters are large, fat, good meat and delicious. In 2008, "Rushan Oyster" was officially approved and announced by the State Administration for Industry and Commerce as a geographical indication trademark.

5. Chenzhou oysters.

Morning Island Oyster Island has a mild climate, small temperature difference, abundant rain and abundant sunshine, making it an excellent place for oyster farming. The meat of Chenzhou oysters is milky white, and the meat is not only strong but also a little more crispy, and the taste is thick"Ocean milk"The reputation of its fat, tender, fresh and beautiful is known in all directions, and its Chenzhou oysters are exported to Shenzhen, Guangzhou, Hong Kong and other places.

Oysters live in hard areas of the ocean floor called oyster beds, which are located in deep or shallow seawater or salty estuarine waters. Oysters live in the middle of the intertidal zone.

Oyster sessile shellfish. Generally, it is fixed on shallow sea objects or seaside reefs, and feeds and respires by opening and closing shells. It is a filter-feeding hail organism that feeds mainly on fine zooplankton, diatoms and organic detritus.

As a high-quality marine cultured shellfish, oysters not only have the edible value of delicious meat, but also have high medicinal value because their meat and shell can be used in medicine. Oyster meat contains a variety of amino acids, glycogen, a large number of active trace elements and small molecule compounds, and its shell contains a large amount of calcium carbonate.

Now there are two major oyster producing areas in China.

Zhanjiang Oysters and Oysters are both famous for their oyster farming, but the season is different. Because Zhanjiang oysters are warm water oysters, they are generally marketed in summer. Many barbecue stalls have summer oysters, which are basically produced in Zhanjiang.

Rushan oysters are marketed after the beginning of winter and before Qingming in the following year. At present, the main products sold in the market are Rushan oysters.

In line with the principle of "cold water oysters, hot water clams", the sweetness and fatness of Rushan oysters should be higher than those of Zhanjiang oysters. Because the lower the water temperature, the longer the oysters will grow, and the more firm the flesh will be. I generally don't dare to eat Zhanjiang oysters raw, they are roasted or steamed, but Rushan's oysters can be eaten raw, and I dare to eat them raw.

After all, the temperature in winter is low, and bacteria are not easy to grow.

Third, the best oysters are in Dalian.

Dalian is strategically located, where the Yellow Sea and the Bohai Sea meet, providing abundant food for the growth of oysters. Dalian is located at 39 ° north latitude ** seafood production line, where there is no severe cold in winter, no heat in summer, and the seafood produced can be said to be well-known throughout the country.

Dalian Silver likes to eat oysters the most, so Dalian Silver speaks with "oyster flavor". Oysters are produced in Changhai County, Zhuanghe, Jinzhou and Lushun in Dalian because the sea water is clean and the temperature is suitable. Therefore, the oysters produced are firm and the soup is clear, especially the small oysters in the stone crevices of Lushun.

Although the production of oysters in Dalian is okay, it is because the locals love to eat it too much! Therefore, the local area is not enough, and it is difficult for outsiders to taste it, resulting in it is difficult to see Dalian oysters in other markets, which has to be said to be a pity for friends from other places.

Tips for eating oystersIt is best not to use iron knives when picking the shell of oysters, as this will cause the oysters to stain the smell of iron and affect the taste of the oysters. Use a stainless steel knife to pry the shell. During the steaming process, the puffed side should be turned down so that the juice of the oysters will not be lost after opening.

If you want to open the oyster shell to get the meat, you can use the microwave for about 1 minute, or freeze the oysters directly to the opening, which will make it easy to take the meat.

When preserving oyster meat, be sure to soak the oyster meat in its body fluids and freeze it, so that it can be stored for a long time and the umami will not be lost much after thawing. I haven't eaten oysters from overseas, so it's hard to comment. If you want to say that the best oysters in China are the most delicious, then it must be "Dalian", which is not refuted.
