Oysters are also called oysters.

Which places produce oysters?

Our country is widely distributed, starting from the Yalu River in the north to Hainan Island in the south. Oysters can be produced along the coast.

Oysters are soft-bodied, shelled, parasitic animals, and are particularly plump when produced at the junction of saltwater and freshwater.

There are a lot of wild oysters in Dalian Bay, Omi, Zhejiang, Fujian and Guangdong, and more of them are farmed oysters.

In the south, it is undoubtedly Zhanjiang oysters in Guangdong.

As long as you go to eat, whether it is a big hotel or a small restaurant, whether it is a roadside stall or a vegetable market, it will say "Zhanjiang oysters." In addition to Zhanjiang, Guangxi, and Yangjiang, the oysters are also very good.

Why there are so many oysters in these places is mainly determined by the living habits of oysters: oysters have a fixed life for life since they are attached. They cannot move away from the fixed objects and can only open and close their shells.

The left shell is fixed, and only the right shell can open and close.

And rely on the opening and closing movement of the right shell to carry out living activities such as breathing, feeding, reproduction, and excretion.

When encountering adverse environmental conditions, the shells close tightly to survive the storm.

The long oyster is a broad-temperature shellfish that can live in water temperatures of 0-32°C, and the optimal water temperature for growth is 15-25°C.

It also has a wide adaptability to salinity and is distributed in the salinity range of 10-40‰. It grows quickly in sea areas with low salinity.

Oysters mainly feed on single-cell plankton and organic debris.

There is no special regularity in feeding. Generally, feeding is vigorous when the water temperature is 10-25°C, but during the breeding period, the feeding intensity is relatively weakened.

In addition, 80% of global oyster farming is in China.

It was very hot in Denmark a few days ago and there was a flood of oysters. Apart from oyster passports, imports really couldn't help them.
