Recently, Ruzhou City, Henan Province, spent nearly a month of pumping and fishing, and finally caught the crocodile crickets in the central park of the city. The whole process attracted over 30 million netizens to watch. Many people first met this fierce "strange fish". They also knew that it was an external invasive creature that would not only prey in other aquatic animals, but also attacked people.

In fact, this is not the first time that the crocodile bird has appeared in China. In the past few days, Guangdong, Yunnan, Sichuan and other places have reportedly discovered crocodile crickets. In Shanghai, some netizens even broke the news that there was a fishing base in Songjiang that specialized crocodile crickets for fishing. Where do these crocodiles come from? Since it is a surrounding foreign invasion species, why do people specialize in breeding, isn't it illegal? In response to the concerns of netizens, the Shanghai rumor platform was investigated.

Some people buy and sell, some people breed

In the "Fish Friends Circle" and "Fisheries Circle", the crocodile is not unusual.

"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." It is no stranger. 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." The crocodile crickets are long, but according to the variety and living environment, not each will grow to one or two meters, two or three meters long, "usually about sixty or seventy centimeters." He analyzed that the reason why he appeared more than there was more place. 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, cannot be released. "

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.

Some crocodile sparrowers said that fish breed their own, "raising this kind of fish is not illegal." In addition to the buyer, some people bought the crocodile cricket as an ornamental fish, and some fish ponds bought raising for fishing. "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."

Can't release or discard

Isn't it illegal for breeding and buying and selling crocodiles, is it 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, said.

He introduced that crocodile crickets were native to the Americas. They were weird and fierce. They basically had no natural enemies in China and belonged to foreign invasive species. Because it meets the psychology of some consumers' curiosity, it was introduced into China for reproduction earlier in the early years, mainly as an ornamental fish. "Candiden -crocodile criminals often enter the country through smuggling. So from the source, it is illegal to introduce crocodile crickets." At the same time, according to April 15, 2021, the "Biological Safety Law of the People's Republic of China" is implemented. Playing and discarding crocodile birds is also illegal.

The Biological Safety Law is clear that without approval and introduce foreign species without authorization, the relevant departments of the people's governments at or above the county level shall be divided into labor according to their responsibilities and confiscate the introduced foreign species, and shall be fined by 50,000 yuan or less. For approval, if you release or discard foreign species without authorization, the relevant departments of the people's governments at or above the county level shall order foreign species that will be arrested, retrieved or discarded according to their responsibilities, and shall impose a fine of 10,000 yuan to 50,000 yuan.

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

As for breeding and buying and selling crocodiles, it is not completely unlikely. The Biological Safety Law pointed out that violations of biological safety violations stipulated in this Law did not stipulate legal responsibilities, and other relevant laws and administrative regulations stipulated in accordance with its provisions.

Gu Dangen said that with the increasing attention of biological safety, my country has released multiple batches of "national key management of foreign invasion species". The management will become more and more stringent. At that time, the breeding and breeding of crocodiles may be restrained. "

Can't be raised, can I eat it?

Some netizens asked, can crocodile cricket be eaten? Gu Dang En said that this is not desirable.

First of all, the eggs of crocodiles are poisonous. 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 and 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. The fish itself is not good.

Overall, the value of this fish is not high.

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 people's release.Cromis.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.
