Recently, in an artificial pool in a small area of Guangzhou, a mysterious biological invasion incident occurred, and many fish stocked in the pool were bitten only halfway! Later, with the efforts of the property security personnel, the culprit of the bite in the pool was finally caught.
According to Mr. Zhou (pseudonym) from Guangzhou, there is a relatively large park pool in his community, which contains a lot of ornamental fish for residents to walk and watch. In his spare time, he would take his daughter to the pool to play and watch the fish feed the fish.
But recently a lot of dead fish were found in the pond, and it is not strange to find dead fish, but these fish are not normal deaths, and each fish is bitten off by an unknown creature!
When he first found out, he didn't pay much attention, thinking that it should be a wild cat catching and eating, and didn't finish eating the rest. But in the next few days, the dead fish became more and more, even if it was a cat, the fish were in the water, it was impossible to catch so much, nor could it eat half and leave half so wasteful, obviously by other animals.
In order to solve the doubts, Mr. Zhou also inspected the pool, because there were many rock rocks in the pool, and there were some lotus roots in it to block the view, and he turned around twice and did not find anything abnormal.
The next evening Mr. Zhou took his daughter to the pool to feed the fish, and when he was feeding the fish, he inadvertently turned his head, and then found that there was a black shadow of about one meter on the side of the rocks in the water, he hurriedly got up and looked at it, and the black shadow saw that there was movement, and did not flee, but swam to his side.
At that time, he thought it was a crocodile, and this was enough, so he subconsciously picked up his daughter and ran to the shore. After waiting for a while to find that the thing did not climb ashore, Mr. Zhou put his daughter in a safe area before slowly walking to the edge of the pool to check.
The unknown creature in the water did not leave, but swam closer to the shore, which I seemed to have seen somewhere, Mr. Zhou pondered. Then he quickly took out his mobile phone and snapped two photos, and as soon as he finished taking them, the thing swam into the lotus bush and hid.
When he got home, he showed his daughter-in-law the picture and asked if he knew what it was? His daughter-in-law looked at it twice and said isn't that what crocodile eel is? After reading it on the Internet, Mr. Zhou remembered that he had also seen it on the Internet, and it turned out that it was the fish that this thing bit, and he understood.
The next day he found the property in the community and told them about it, and the property did not believe it at the time, saying how there could be this alien species in the community pool. Mr. Zhou took out the photo he took with his mobile phone on the spot, and after seeing the photo, the property staff was still suspicious and thought that it might be a big grass carp!
In order to verify the authenticity, the property transferred two pumping machines in the afternoon and began to round up the pool. Because of the large size of the pool and the varying shades of the pool, the property and security personnel were busy from three o'clock in the afternoon until seven o'clock in the evening, and the crocodile eel was finally caught when it was dark.
At that time, there were many people in the community, and everyone also took out their mobile phones to take pictures, from the photos we can see that the fish's mouth is very long, and the sides of the mouth are covered with sharp fangs, no wonder it is called the crocodile eel, and the mouth shape is really similar to the crocodile.
Mr. Zhou speculated that the crocodile eel was deliberately released by someone because it is not a native fish, it is an invasive alien species, and if no one releases it, it will certainly not appear in the pool. Fortunately, it was found in time, and in a few days, the fish in the pool would be eaten clean by it.
Originating from North America, the alligator eel is a ferocious, large carnivorous freshwater fish with the title of "killer in the water", and as long as it exists in the waters, other fish inside will suffer. An adult alligator eel can eat dozens of pounds of freshwater fish a day, not to mention a pool, even in the river, the fish is not enough for it to eat, the ecological harm to the fishery is very large.
The mainland has long had a clear stipulation that it is forbidden to breed and release crocodile eels, and once found, it will be punished. Fishing fishing, seeing, catching, should be immediately notified to the relevant departments, but also can be eliminated by themselves. Finally, the fish eggs, internal organs, teeth, and teeth of the crocodile eel are toxic, but the meat is not poisonous, if you want to eat, you must treat the toxic parts cleanly, so as not to cause the risk of poisoning after eating, we must remember.
