"The "strange fish" of Ruzhou in Pingdingshan, Henan Province, has been caught! ”
The Ruzhou crocodile eel fishing incident finally ushered in the final moment of the play. Let's review the process of the "strange fish" incident in Ruzhou.
On July 15, the Ruzhou garden has organized fishing, but due to the large water area and complex underwater conditions, the fishing has been fruitless. The video taken by local citizens showed that the "strange fish" was larger, with sharp beaks and long teeth, and a patterned body.
On July 16, a park in Ruzhou, Henan Province, hunted a "water monster" at night, and the garden was suspected to be a crocodile eel suspected of being an alien harmful species.
On the afternoon of August 23, the reporter contacted a staff member of the Ruzhou Municipal Government and said that the "strange fish in the lake" was determined to be a crocodile eel, and the arrest work was still in progress. Police responded to the incident of pumping water to catch "strange fish in the lake".
On August 24, the official response was to drain more than 200,000 square meters of lake water to catch "strange fish", which was determined to be a crocodile eel, afraid that it would hurt people; The water in the lake where the crocodile eel is located has been drained, and the person in charge: it may be hiding in the culvert.
On August 25, Ruzhou Fire Brigade, Blue Sky Rescue Team, Fengma Banner Rescue Team and other staff prepared for fishing work at the scene, and the staff introduced that the set of nets used for fishing was 100 meters long, 10 meters wide and 15 meters deep, and could withstand about 150 kilograms of fish. The alligator eel is basically locked in a U-shaped culvert connecting the lower reaches of the lake. Fire rescue team personnel put on protective clothing and entered the crocodile eel to hide in the culvert; Park administrators said experts speculated that the alligator eel was suspected of being "thought to have been released."
On the evening of August 26, the park management responded that the lake water was drained to catch strange fish, not a show, and it would last for several days. In the evening, two crocodile eels have been caught, and the park management has treated them harmlessly and arranged for personnel to professionally disinfect the lake area.
On August 27, two crocodile eels in Ruzhou Lake, Henan Province, were captured and treated harmlessly. The arresting team members recounted the arrest process: pumping the water almost to the point of going into the pipeline more than 100 meters deep to capture it; The person in charge of the operation and maintenance management of the park, the sex of the fish and whether they will spawn also need to be identified.
Looking at the picture above, this is the largest of the two "strange fish" caught in Ruzhou, and one is about fifty or sixty centimeters long. It has been confirmed that these two fish are alien species crocodile eels, but it is not certain whether they are one female and one male, the two fish have been taken away by the agricultural department of Ruzhou City, and the sex of the fish and whether they will spawn need to be identified by the relevant departments.
At the beginning, in the face of some different voices of "strange fish" on the Internet, the response of the relevant departments of Ruzhou City Park mainly has three aspects: First, it is worried that crocodile eels may hurt people, which is also related cases in China; Second, crocodile eels destroy the ecological environment of Yunchan Lake, if not managed, it is likely that the fish in a lake will be eaten by them; The third is to worry about the breeding of crocodile eels in the lake, to know that crocodile eels lay hundreds of thousands of eggs at a time, and many will hatch successfully in the absence of natural enemies.
Alligator eels, known as "aquatic killers" or "freshwater killers", carnivorous fish, are prehistoric fish that have lived on Earth for more than 100 million years, and their flourishing period was in The Jurassic entry and early Cretaceous period. Aliases: Ghost Rocket, Big Sparrow, Hammer Bone Gar, Crocodile Rocket. The alligator gar and the Cuban gar eel, the tropical gar eel, the spotted gar eel, the longnout gar eel, the shortnose gar, the Florida gar eel are the 7 largest gar eels in North America, and the alligator gar is also the largest of the 7 species of gar eel in North America, so it is also known as the largest gar gar.
Alligator eels are 1.2–1.8 m long and weigh 45–72 kg, with females slightly larger than males. The fish has a long barrel shape, a protruding snout, a crocodile-like short snout and two rows of dagger-like sharp teeth on the upper and lower jaws, hence the name.
It is mainly distributed in North America, a freshwater fish, mainly distributed in the Gulf Coast rivers and estuaries from Mexico to Florida, the lower Missouri and Ohio rivers, and even two lakes in Nicaragua. Its viability is very strong, internal organs and fish eggs are highly toxic, not only fierce temperament, but also bite people, mainly to prey on fish in the water, if placed in natural waters, it will bring disaster to the local water ecosystem, it is said that "a crocodile eel can eat a fish in a lake." It is said that in Guangdong Province, a farmer's fish pond was once "mixed" with two crocodile eels, and as a result, within a month, the entire fish pond was eaten.
Coincidentally, in the mainland, Ruzhou, Henan province has been found many times is not the first time crocodile eel, for example: Changsha, Hunan: crocodile eel appeared for the first time by the public to catch; Yinchuan, Ningxia: Crocodile eel tracks were found by the bridge during walking; Kunming, Yunnan: Crocodile eels appear in the ponds of the community; Jingjiang, Jiangsu: Children are bitten by "strange fish" in the landscape pool of the community; In a pond in Xiamao Village, Shijing Town, Guangzhou, a nearly 90-kilogram "crocodile eel" was caught by people and so on. People talk a little bit about the feeling of eel discoloration, and there is a sense of fear of it.
From the analysis of the two crocodile eels caught this time, the size of the body can be concluded that it should be a male and a female, indicating that they have the ability to reproduce. Crocodile eels mate and spawn in May-August every year, females lay 140,000-200,000 eggs each time, but only a few luckily escape natural enemies and successfully hatch, the eggs are pale green, sticky, adhere to aquatic grasses or gravel, the incubation period is about 6-8 days, males are about 6 years old sexually mature, females are up to 11 years, lifespan is 26-50 years, the highest record is 75 years. It's the end of August, which means two alligator eels may have spawned, which is an extremely dangerous sign. If you do not catch these two fish in Ruzhou in time, there may be a lot of small crocodile eels in the back, and when the fish in the lake are eaten, the crocodile eels will pose a personal threat to the citizens when they grow up, and they may attack humans because of lack of food, which is a big deal. Therefore, although it takes a lot of manpower, material and financial resources to drain more than 200,000 square meters of lake water and catch two "strange fish", it is also worth it.
After the "strange fish" incident in Ruzhou, Henan, there were media reports that many merchants had previously found that many merchants were selling seedlings and live fish, and many e-commerce platforms were urgently removing crocodile eels. Crocodile eels first entered China as "ornamental" fish, they have a peculiar shape, a mouth very similar to a crocodile, and the scales and hard brilliance are also more beautiful, and they are raised as pet fish. However, crocodile eels are carnivorous fish, which is expensive to raise, and as they grow larger, the fish tank simply cannot hold them. Therefore, ordinary families will find that they cannot afford to keep them, so that they will eventually abandon them to natural waters.
Zhou Zhuocheng, an expert of the China Fisheries Association, said that the crocodile eel is an invasive alien species, according to the location of the incident, it is speculated that it may be abandoned by residents as ornamental fish farming, and the species has no natural enemies in the landscape pond, which will seriously damage the ecological balance of the waters and cause irreparable losses to local fish resources and species, so it is recommended that everyone should not discard and release at will.
On April 15, 2021, the Biosecurity Law of the People's Republic of China and the Measures for the Administration of Invasive Alien Species came into effect on August 1, 2022. No unit or individual may introduce, release or discard alien species without approval. Those who introduce, release or discard alien species without the approval of the relevant departments will be punished in accordance with Article 81 of the Biosecurity Law of the People's Republic of China, including crocodile eels.
