"Crocodile Trone" invades rivers and lakes in many places?

Ruzhou and Ningxia Yinchuan in Henan discovered traces

Witnesses, Mr. Wang, told the cover reporter that the earliest video of this "strange fish" was at about 18:10 pm on June 24, 2022, the place was to go to Taqu Street, Jinfeng District, Yinchuan City, Ningxia. Go to the bridge of Zhonghai International.

He recalled that when he and his lover strolled around the bridge at that time, he found that in the Diannong River, there was a sharp mouth and a slender body swimming. Out of curiosity, Mr. Wang filmed this scene. I have loved fishing since I was a child. I have never seen such fish for a long time. "

Mr. Wang said that he filmed this video and sent it to an expert and friend who is familiar with aquatic and aquatic animals. This friend told him that from the characteristics of body shape and swimming, this "strange fish" is actually crocodile, belonging to the genus of the bird, the genus of the tit, and the big bird, and the largest in the existing type of the sparrow. One of them can be up to 3 meters, mainly eating other fish and meat. Because the mouth is like a crocodile, it is called a crocodile.

Friends also reminded him that crocodile crickets belong to foreign invasive species, which will cause certain ecological damage to the local natural waters, but in Yinchuan, I have not heard much about the news of crocodile crickets.

"Strange Fish" in the water is suspected

Yinchuan Agricultural and Rural Bureau and other departments intervene

Mr. Wang told reporters that at the beginning, he was kept in his mobile phone without publishing this video. Until he saw the news of Ruzhou in Henan, he sent the video to the Internet.

"Later some media in Yinchuan and the agricultural and rural bureaus also saw it, so I contacted me." Mr. Wang described that from his many years of local fishing experience, when he saw the crocodile crickets on the same day, he should belong to human release. Soon, "because of the judgment of experience, the fish that generally released will float on the water, but when it adapts to the water environment and temperature, it will dive into the water."

Mr. Wang said that the crocodile can generally grow to more than three meters and weigh more than 200 kilograms. There are sharp teeth like crocodile. Public information shows that in the case of insufficient food, crocodiles and even the same kind of disability, and their eggs are toxic to mammals including humans. This fish enters only artificial lakes with a large area. If you enter large reservoirs and rivers, the consequences will undoubtedly be more serious.

It is understood that before, the "strange fish" found in Yunchen Lake, Ruzhou City, Henan Province was suspected to be crocodile. According to the data, the crocodile cricket is native to North America, and its body is covered with a hard scales of a layer of diamond -shaped glaze layer. It has a short kiss and two rows of dagger -like teeth like crocodiles. Nearly 300,000 cubic -cubic lakes were basically dry after a month of pumping, but no crocodile crickets have not been captured.

With the fermentation of "dry lake and water fishing fish" on the Internet, the news of "Yinchuan's local crocodile crickets" was also spread. Essence On August 25, the Office of the Yinchuan Municipal Party Committee "Ask Guanzheng Yinchuan" stated that it had paid attention to the matter and asked Yinchuan Rural Agricultural Bureau to handle it.

Crocodile Cripladiacs Foreign Invasive Species

Natural migration and human release are channels

The reporter sorted out related reports with crocodile crickets. In his early years, crocodile crickets have appeared in the wild distribution records in Guangdong, Guangxi, Fujian, Henan, Sichuan, Jiangsu and other provinces in my country.

Among them, in May 2022, the crocodile crickets appeared in a community in Zigong, Sichuan as an example. After fishing by fishing enthusiasts, it was harmless after fishing. At that time, some experts said that crocodile crickets were originally introduced as ornamental fish, and they often appear in zoos and aquariums. Some domestic ornamental fish enthusiasts will buy crocodile crickets and be kept as pets as pets.

Some experts said that some crocodiles that are raised by artificially will be released in the wild by the owner, but this way of "release" to the wild pond or artificial lake will cause serious damage to the local ecological environment. "Because crocodile crickets are almost omnipotent, including fish, crustaceans, amphibians, birds, etc., as long as they are living things in the water, they may be prey."

According to the 2020 China ecological environmental status released by the Ministry of Ecology and Environment, more than 660 kinds of foreign invasion species have been found in the country, of which 71 types have caused or have potential threats to the natural ecosystem. Related information shows that there are two main channels for the invasion of these foreign species. One is natural invasion. Through air flow, water flow, or bands of insects and birds, plant seeds or animal larvae occur naturally, causing biological hazards. Second, man -made introduction, whether intentional or unintentional, will also become a way to invade foreign species. Experts remind: Don't release it at will or discard crocodiles

On the afternoon of August 26, in response to the news of the crocodiles in many places across the country, cover reporters also interviewed Mu Xidong, a researcher at the Pearl River Aquatic Research Institute of the Chinese Academy of Aquatic Sciences and the director of the key laboratory of the aquatic biological prevention and control of the Agricultural and Rural Ministry.

He told reporters that the crocodile cricket belongs to the "foreign invasion species". According to the "The Biological Safety Law of the People's Republic of China" formally implemented on April 15, 2021, it stipulates the content of preventing foreign species invasion and protecting biological diversity. Invasive species list and management measures. To this end, this year's Ministry of Agriculture and Rural Affairs and other relevant departments have formulated the "Notice on Printing and Distributing the General Plan for the Census of Foreign Invasive Species" to conduct a nationwide census of 10 major foreign aquatic creatures, including crocodile crickets.

Mu Xidong said that because the adaptability of crocodile crickets is very strong, it belongs to meat fish and has a armor -like fish scale, so in the waters of my country, it generally does not exist. The water body ecosystem has a very serious impact. "

Mu Xidong suggested that when ordinary citizens encountered crocodile in the wild waters, they suggested that they immediately report to the local agricultural and rural areas and other departments to inform relevant professional teams for fishing.
