In order to catch a fish, the Central Park of Ruzhou City, Henan Province, drained a lake of water, about 200,000-300,000 cubic meters of water. One might ask? There are also people who are curious about why it costs so much to catch this fish, and this article will take you to understand.
What kind of fish is this?
In fact, as early as last month, a local resident found a strange fish in the Central Park of Ruzhou City, and after experts distinguished it, it was found that it was an invasive species "crocodile eel".
Crocodile eel mouth like a crocodile, the body scales are very hard, like wearing a thick layer of armor, the mainland native fish can not help it, and it will feed on the mainland native fish, they will not only eat fish, but all the living creatures in the water they will eat, once settled in the local area, they will kill all sides, every day to eat equivalent to 5% of their own weight, long-term 1 fish can eat the fish of the entire lake.
In 2016, a fish farmer found a crocodile eel more than 1 meter long in his fish pond, and as a result, more than 5,000 fry that had just been put down half a month ago were all eaten by the fish.
After the discovery of the crocodile eel in ruzhou City Central Park, the local people also found that the number of fish in the lake began to decrease, if it is allowed to continue to stay in the lake, then the entire lake will become its hunting ground, which is a "disaster" for the native fish, shrimp and snail mussels.
In fact, crocodile eels will not only endanger the fish shrimp snail mussels in the water, but also dangerous to humans, just a few days ago, a small boy in Taizhou, Jiangsu Province, when playing in the water in his own community pool, accidentally bitten by a strange fish 3 fingers, the property and local residents immediately pumped the pool, and sure enough, the culprit was the crocodile eel. And this crocodile eel is only a "small fish" with a body length of 70 cm and a weight of more than 10 pounds, if left unchecked, they can grow to 3 meters, 200 pounds, not to mention children, even adults they dare to attack.
If you play in the area where the alligator eel is active, you may be attacked by the crocodile eel, the crocodile eel is fierce, there is a possibility of hurting people, although the probability of hurting people is small, but after all, the Central Park is crowded, there are many children, if not salvaged in time may pose a certain threat to the local residents.
More importantly, the alligator eel reproductive ability is very strong, each spawn up to 150,000 pieces, fish eggs and toxic, once the crocodile eel in the local establishment of a stable population, for the local ecology can be described as a disaster, its existence can be said to be a hundred harms and no benefits.
In order to protect the local ecological environment, but also in order to protect human beings, the staff of Ruzhou Central Park was prepared to fish the fish at the very beginning, and last month there were multiple rescue teams fishing operations on the lake, but the underwater situation was complicated, the lake area was very large, the crocodile eel teeth were very sharp, and there was also a risk of injury during the salvage process, and it was difficult to catch it with the fishing method, because the sharp teeth of the crocodile eel could bite off the fishing line.
This also led to the salvage is not smooth, multi-day salvage did not "arrest and arrest" the crocodile eel, helplessly the local had to pump water to fish, in nearly 1 month, pumped about 200,000-300,000 cubic meters of water, is currently entering the final stage, basically this crocodile eel will definitely be caught and arrested.
The question now is not whether this alligator eel can be caught, but the alligator eel is not a native species of the mainland, but alligator eels have appeared in many waters across the country in recent years. And are there any other crocodile eels in the lake besides this crocodile eel?
How did the alligator eel come about?
Crocodile eels do not originate on the mainland, so how did they come to the continent?
In fact, the main reason why crocodile eels come to the mainland is not because of eating, but "ornamentation", crocodile eels have a peculiar shape, a mouth very similar to a crocodile, and the scales and hard brilliance are also better looking, and are raised by some people as pet fish.
But what they don't know is that the crocodile eel grows very fast, reaching an adult size of about 3 meters, and the family fish farming space is limited, and the family space will be difficult to accommodate after raising.
Secondly, crocodile eels are carnivores, and the cost of raising crocodile eels is very high.
Coupled with the thick flesh of the crocodile eel's skin and the hard and large scales, it is very difficult to eat fish. Crocodile eel eggs and ovaries are highly toxic, eating it can lead to death, Heilongjiang once had a man bought crocodile eel fish meat and 2 two roe, after cooking invite friends to taste, resulting in 3 people poisoning.
Because the alligator eel is not a native fish of the mainland, even the local doctors do not know how to treat, fortunately, they do not eat much, plus they are relatively strong, the doctor's careful treatment finally turned the crisis into safety.
On the one hand, people don't want to raise them, on the other hand, crocodile eels are thick and unpalatable, and the eggs are highly poisonous, plus people don't know what to do with them, so that they are eventually abandoned in natural waters.
In 2016, when the police of the Chancheng High-tech Police Station patrolled the river to prevent drowning, they found that someone was suspected of being released by the river. The police immediately interrogated him and found that the man was going to release a 70-centimeter crocodile eel.
The man said that this crocodile gar is its pet, the result of a few months quickly grew from 10 cm to 70 cm, and every day to spend 20-30 yuan to buy fish and shrimp to feed, unable to afford to want to release it, the result was found by the police.
In addition, there are some "caring people", in the name of doing good deeds, randomly release raw fish, and crocodiles and eels are mixed in and released into the wild.
Crocodile eels in Ruzhou City Central Park may also be deliberately released, and last year in the lake found a crocodile eel was salvaged, this year there is another crocodile eel, if not artificial release, crocodile eel is difficult to get here.
In fact, in addition to the Ruzhou Central Park, crocodile eels have been found in many lakes, artificial ponds and natural waters on the mainland, and most of these crocodile eels are released by people at will.
In addition to crocodile eels, people also randomly release Brazilian turtles, bay crocodiles and other exotic species, causing great damage to the local ecology, these so-called "caring people" are actually doing evil in the name of good, the local police said that the random release of alien species is illegal, I hope that people will not release them at will.
At present, the crocodile eels in Ruzhou Central Park are still in the process of arrest, and when the water level has completely receded, the local area can see how many crocodile eels are in the local area, take advantage of this opportunity to catch them clean, and take strict precautions to set up a sign prohibiting release, so as to prevent the crocodile eels from being released into the lake by the so-called "caring people".
