Is it a special breeding?

For more than a month, Beijing, Henan, Hunan, Ningxia, Shandong and other places have reported crocodile crickets. Yesterday, "a man in Shanghai fishing for a crocodile" attracted attention. According to relevant videos, the crocodile crickets here are fed for the fishing base and provided them to the Fishing Party.

Why do you have to catch Gan Ge?

Where do these crocodiles come from?

Why does someone specifically buy and sell and feed not illegally?

Can I eat it?

Four questions

1. Why is it necessary to move Ge Ge?

Known as "freshwater killer"

In July of this year, citizens in Ruzhou, Henan found that there were "strange fish" in the waters of Yunchen Lake in Central Park. Originally, the park thought it was a big fish, which did not work. After the expert identified, this was suspected to be "crocodile". After the bait failed, the lake of 200,000 to 300,000 cubic meters of Yunchen Lake was finally removed, and two crocodile baptis were won.

In order to fish dried the lake water, the practice of moving the Gan Ge originated from the harmfulness of this species. The crocodile crickets are freshwater giant carnivorous fish native to North America, with sharp teeth, and a pair of "heavy armor". It predates Chinese species in my country, especially fish in the waters. The algae that is used as food will be flooded in large areas. Aquatic plants form a single species of advantages, which may lead to hypoxia and cause ecological disasters within a certain range. Therefore, the crocodile cricket is also known as the "freshwater killer".

2. Where do these crocodiles come from?

Earlier as "ornamental fish" entered the national gate

Ordinary people may be the first time that I know crocodile, but in the "fish friend circle" and "fishing friends circle", the crocodile crickets are not unusual.

It is understood that the earliest it entered the country as "ornamental fish" and breeding and breeding in some areas. It is one of the traditional market varieties. In Guangdong, which has developed fish trade in my country, the birds are also crowned by a nice name -the crocodile.

It is not new to appear in Shanghai in Shanghai. "In recent years, in the natural river channels in Shanghai, it will be found once or twice a year. At some leisure experience bases, some people will specialize in breeding crocodiles for citizens to fish." Captain Yang Weihua told reporters that crocodiles were raised by people in the city as pets. Due to the fast growth rate and difficulty in having aquarium tank, some owners would discard them in the wild.

3. Since it is a surrounding foreign invasion species,

Why are there still people who specialize in buying and selling and breeding, isn't it illegal?

Seller: breeding does not violate the law

The truth is ...

"This fish is also called a crocodile, a sparrow, and a ghost rocket. It looks strange. It belongs to the fierce fish. Some people like it and will buy it specifically." No stranger to it. It is a unique appearance. There are juvenile fish sold on the market. "Most of the sellers in Guangdong, the price of juveniles is not expensive, it is about 10 yuan." Soon, according to the variety and living environment, not each will grow to one or two meters, two or three meters long. "Usually it is about sixty or seven or eighty centimeters." He analyzes Crocodile birds, do not rule out that some people find that a head grows too fast or too big after breeding, "this is dangerous. Senior fish friends know that crocodile crickets are foreign invasive creatures, and there is no in China in China. Natural enemy, you can't release it. "

Under the guidance of Mr. Zou, the Shanghai rumor platform browsed some e -commerce websites and found that there is really a crocodile larch juvenile. In the past few days, or because the public has paid attention to this is a harmful foreign invasion species, many platforms have shielded the search results of "crocodile birds" as keywords. However, searches such as "blessing", "birds", and "ghost rockets" are still searched, and there are still some sellers.

Search with the other name of the crocodile and even the wrong name, and you can still find the living young seedlings seller

Some crocodile sparrowers said that fish breed their own, "Raising this kind of fish is not illegal." He said that in addition to buying crocodile crickets as ornamental fish, some fish ponds bought for raising for people to fish. "This kind of fish is more fierce, and some people really like it. The law only says that they cannot be released, and they cannot be raised."

However, the owner also acknowledged that recently the crocodile bird's attention is very high. Everyone noticed the safety of breeding. "The platform is tightening and it is not easy to publicize. We will also remind buyers that this kind of fish can only be viewed. Forbidden to release. "

According to some "fish friends" and dealers

Is it true that breeding and buying and selling crocodiles are not illegal. Is this true?

"It can only be said that the existing laws and regulations are not prohibited, but from the perspective of biological safety, it will definitely not advocate breeding and buying and selling crocodile." Gu Denan, an invasive expert, told the Shanghai rumor platform.

He introduced that as netizens learned, crocodiles were native to the Americas. They were weird and fierce. They basically had no natural enemies in China and belonged to foreign invasive species. However, because it meets the psychology of some consumers' strange hunting, it was introduced into China for reproduction in the early years, mainly as an ornamental fish. "The creeper is often entered the country by smuggling. The birds are already illegal. "At the same time, according to the" Biological Safety Law of the People's Republic of China ", which was implemented from April 15, 2021, it is also illegal to release and discard crocodile birds. The Biological Safety Law is clear that "without approval and introduced foreign species without authorization, the relevant departments of the people's governments at or above the county level shall confiscate the introduction of foreign species introduced by the division of labor according to their responsibilities, and impose a fine of 50,000 yuan or less." "If it is unauthorized or discarded by the people's government at or above the county level, the relevant departments of the people's governments at or above the county level shall be ordered to capture, retrieve foreign species that release or discard the release or discard. "".

It can be seen that the introduction of, release, and discard crocodile tincture must bear legal responsibility.

In 2019, crocodile crickets were also captured in the first park of Foshan

As for breeding and buying and selling crocodiles, it is not completely unlikely. The Biological Safety Law pointed out: "If the violation of the biological safety violations stipulated in this Law, the law does not stipulate legal liability, and other relevant laws and administrative regulations are stipulated in accordance with its provisions."

Gu Dangen also said that as biological safety is getting more and more concerned, my country has released multiple batches of "national key management of foreign invasion species". The management of creatures will become stricter and stricter. At that time, the breeding and breeding of crocodile can be restrained. "

4. Can't be raised, can I eat it?

Toxic is poisonous, there will be life -threatening after handling improperly.

Some netizens asked, the crocodile bird is so big. Since it is harmful, can it be eaten as a food fish variety? Gu Dang En said that it was not advisable.

First of all, the eggs of crocodiles are toxic. If it is not handled, there is danger to life after eating. To know. The crocodile crickets are not only growing fast, but their fertility is amazing. It can reach sexual maturity in 3 years under breeding conditions. The amount of eggs is more than 5,000 capsules per kilogram. Some are higher and it is very difficult to deal with.

Secondly, the crocodile bird is not delicious. He said that some gourmet enthusiasts in Guangdong have specially studied crocodile crickets, but found that the fish scales are hard and thick, and it is difficult to peel off with the fish. It is not easy to cook. And the fish itself is not good.

Overall, the value of this fish is not high.

Crocodile larva is not recommended to raise or eat it

Gu Dangen feels that for the harmful foreign invasive species such as crocodile crickets, not only must there be strict trade control and breeding control, but also popular science propaganda to prevent the release of human release, and to avoid the public's accidental caught capture and capture. Crocodile bird.

On the one hand, it is not recommended that individuals or enterprises raise crocodiles. The crocodile crickets grow fast and have a large body shape, which is prone to ordinary aquariums that cannot be cultivated. If it is released to the centers and surrounding lakes, reservoirs, and rivers, it will greatly threaten local creatures.

On the other hand, for the crocodile crickets who do not want to continue to raise, it is recommended to contact scientific research units to make specimens for science popularization, and they can also be harmless. This time, after the capture of the crocodile, Henan Ruzhou also carried out harmless treatment and disinfected the waters.

Foreign species or foreign invasion species?

how to respond?

The reporter noticed that since 2003, the "List of China Foreign Invasion Species" has released four batches, a total of 71 species. At present, crocodile crickets have not been included in the list. However, last year, the five departments such as the Ministry of Agriculture and Rural Affairs jointly issued the "Further Strengthening the Prevention and Control Work Plan of Foreign Species Invasion and Control", which clearly proposed the "strengthening supervision of the aquatic species of breeding and promoting the comprehensive governance of water gourd, Fu Shouluo, crocodile crickets and other migrant invasion species. "".

Foreign species and foreign invasion species are two different concepts, which also affects people's response. The former refers to species that have no natural distribution in my country and passed through nature or artificial channels, including all parts that may survive and reproduce in the species. The foreign invasion species refers to foreign species that are introduced to colonize and bring threats or harm to ecosystems, habitats, and species, affect my country's ecological environment, damage the sustainable development of agriculture, forestry, animal husbandry and fishery, and biological diversity.

"Many foreign creatures are not necessarily invading species." Gu Dang's grace took food as an example. They did not have the ability to overwinter, and they would die soon and did not cause harm to the environment. Therefore, they were not included in the list of foreign invasion species before Essence Over time and the deepening of scientific research, people have discovered that this species already has the ability to overwinter, breeding and forming hazards, so it has defined it as an invasive species.

According to previous reports, Hunan, Qinghai, Ningxia, Shandong, Henan, Jiangsu and other provinces reported that crocodile crickets were found. Especially in the Pearl River area of ​​Guangdong, this species has been established. People in the industry said that in recent years, after long -term monitoring, it is found that crocodile crickets can establish natural populations in many watersheds in the south and have also formed harm. Therefore, in response to the new national key management invasion species, experts suggested that crocodile crickets are also included in it, which clearly regulate and requirements for the breeding and trade of this species.

It is worth mentioning that from August 1st this year, the "Administrative Measures for the Management of Foreign Invasion Species" issued by the Ministry of Agriculture and Rural Ministry, the Ministry of Natural Resources, the Ministry of Ecology and Environment, and the General Administration of Customs.It has built strict institutional arrangements for preventing foreign species invasion, clearing the establishment of foreign invasion monitoring systems, building a national foreign invasion species monitoring network, etc., and stipulates that "any unit or individual shall not introduce, release or discard foreign species without approved".
