Recently, Ruzhou citizens reported that a "strange fish" appeared in Yunchan Lake in Ruzhou Central Park. It was large and elusive. According to eyewitnesses, this "strange fish" The body length of the "strange fish" is seventy or eighty centimeters. At first, people thought it was herring or giant catfish. Later, experts judged based on its characteristics that it was highly suspected of being a high-risk alien species, the alligator gar.
"Strange fish" were found in the artificial lake. Local organizations pumped water to look for fish.
After the incident was reported by the media, it attracted great attention from the Ruzhou Municipal Party Committee and Municipal Government. They immediately organized a salvage team to capture and salvage, but the salvage effect was not good and no fish were recovered. , it was finally decided to use water pumps and other facilities to drain the water of Yunchen Lake starting from July 26 to find these high-risk alien species, crocodile gar, in order to prevent the invasion of this alien species.
According to a staff member of the Propaganda Department of the Ruzhou Municipal Party Committee who is pumping water at the site, the entire Yunchan Lake has 200,000 to 300,000 cubic meters of water. If it rains, the lake will have even more water, and the water pumping project will be relatively large. . Nearly a month has passed since the decision was made to start pumping water around July 26, and by August 23, the lake is about to be drained, and the location of the alligator gar has been basically locked. As of press time, the strange fish has not yet been fished out.
How scary is the "water monster" crocodile gar? Why does salvage need to be stepped up?
Yunchan Lake is an artificial lake. Under normal circumstances, the biological population in the artificial lake is relatively stable, and fish schools do not enter the lake through natural migration. So how did the "water monster" in the lake enter?
According to experts from the aquatic products department of Pingdingshan City, the alligator gar belongs to the order Gar, family, and the genus Great Gar. However, the alligator gar is indeed the largest of all gars, reaching a length of up to 3 meters. The head is also wider than other gar. It has a distinctive appearance, with a long cylindrical body, a protruding snout, a short snout like a crocodile, and two rows of sharp dagger-like teeth on the upper and lower jaws.
A reporter checked the information and found that one of this species can eat a whole lake of fish, so it is known as the "killer in the water." Its survival ability is very strong. Not only is it ferocious in temperament, it can also bite people. It mainly preys on fish in the water. According to the size of the crocodile gar discovered this time in Ruzhou City, one mouthful is enough to swallow a 25 cm long fish.
Since the crocodile gar is mainly distributed in the southern part of North America, it is a giant carnivorous fish. It is an alien species in our country and does not have any natural enemies in our country’s ecological environment. Therefore, the emergence of this species in our country will cause harm to our country’s ecological environment. have been damaged, the most direct of which is the decline in the total number of deep-water fish stocks.
How did the "crocodile gar" get into the lake?
Many people are very curious about the discovery of the crocodile gar in an artificial lake in Ruzhou City. How did the fish appear?
According to the analysis of Pingdingshan City aquatic experts, the main reason is blind release. As an ancient species, the alligator gar has a unique appearance, which has aroused the interest of some aquarists in breeding alligator gar. However, as the size of the alligator gar grows larger and larger , eats an astonishing amount, and many aquarists’ home environments are insufficient for breeding, leading aquarists to choose to release them.
Due to its huge size, it is difficult to transport, so many people choose to release it quietly into rivers or lakes near the community. However, as everyone knows, the crocodile gar is like a tiger returning to the mountains, hunting fish in the water, causing the disappearance of local fish and causing serious damage. ecological balance.
In short, the alligator gar, as an invasive alien species, has caused huge damage to my country's aquatic ecosystem, and can seriously lead to the disappearance of some aquatic organisms populations. Therefore, aquatic experts once again remind everyone not to release animals blindly.
