Notice!"Underwater Locust" invasion

Recently, some breeding areas of the Jiaozhou Bay Sea of ​​Qingdao have once again appeared in the outbreak of starfish, and for the first time, the enemy's biological "white mud", predating clam seedlings, causing fishermen's economic losses and causing widespread concern in the society.

What is "White Mud"?

The appearance of "white mud" is milky white, with oval square and translucent. According to Qingdao Marine Biological Experts, the scientific name of "White Mud" is the Crusher Shell, which is an animal in the shells of the shell. It is distributed in waters such as the Bohai Sea, the Yellow Sea, and the East China Sea. "White Mud" grows rapidly, its teeth in the abdominal cavity are developed, and they can prey on breeding shellfish such as clams and oysters.

Some shellfish farmers said that one of their ships caught 200 pounds of "white mud" a day. The staff of the Qingdao Marine Development Bureau said that the size of such a number of "white mud" appeared in Qingdao for the first time. A farmer said, "They can secrete mucus on their bodies. The dense mucus is distributed on the bottom of the sea, which can cause a large area of ​​shellfish to die in large areas of shellfish. They sometimes have more quantities than starfish, really sad. "

Can "White Mud" eat it?

Some netizens asked if this kind of thing can eat? Notice! This creature is likely to cause allergies to the human body. Not only can they not eat, but also very harmful!

Xu Gaogong, a Ocean Development Bureau of Chengyang District, Qingdao City, introduced that there is a "mud of mud", which is mud snails, which can be eaten, but this kind of "white mud" on the bottom of the sea cannot be eaten. Mud snail. Some farmers pile these "white mud" densely together, with a layer of mucus on the surface, and just cut them away. There are small clams that are not digested, and even clams that have just swallowed.

At present, why "White Muda" appears in Jiaozhou Bay scale, it is not known.

What does "White Mud" have to do with starfish?

Both Star Stars and "White Mud" can prey on clams, which are the enemy of breeding shellfish. Stars and "white mud" and "do not invade each other", whether there is a relationship such as predation and other relationships need to be further studied.

It is a terrible thing for farmers to be under the water under the water in a farming area. These starfish will sweep the shellfish raised by fishermen, resulting in heavy losses of farmers. Although starfish has caused huge losses to farmers, after all, starfish can be eaten by people as a high -protein animal, which can also make up for some losses. However, "white mud" cannot be eaten and flooded, which will cause great harm to the farming clams and the situation is not optimistic.
