Video spoilers history, starting with the blitzkrieg on Poland

A new sky appeared.

The camera slowly moves into a pool of turbid water.

An ugly and ferocious fish face covered with rough shield scales emerged from the bottom of the water.

An ugly fish head covered with dark brown spots broke out of the water.

That suction cup-shaped mouth and a body covered with hard scales like armor.

Apparently, it was the infamous scavenger!

I saw this scavenger fish greedily clinging to a rock, its scales glowing with a strange metallic luster in the sunlight.

At first glance, many ancient people were disgusted!
Outside the sky.

Song.

Song Huizong, who loved ornamental fish, couldn't help but frown and feel nauseous when he saw the scavenger fish on the sky.

Then he complained:

"What kind of fish is this? It's so ugly!"

"No, not only is it ugly, it's even ugly to the point where it makes me feel uncomfortable."

"Although I have collected a lot of strange fish in my life."

"But this ugly fish is definitely the ugliest fish I have ever seen."

"what fish is this?"

"Are there many ugly fish like this in the future?"

"I hope there won't be such ugly fish in China in the future!"

And the sky curtain began to tell the story slowly.

【It looks like an alien creature. 】

[Its body is covered with ugly scales, its mouth is like a suction cup, and it can live freely in stinky ditches. ]

[Even out of water, it can still survive for a long time. 】

[It can eat 5000 fish eggs a day, causing the extinction of native fish in an entire area of ​​water, and can be called the terminator of freshwater ecology. ]

【It is a scavenger! 】

【An alien invasive species hated by countless people. 】

[But some people still release animals out of ignorance, causing ecological disasters! ]

【Being ugly can cause great harm. 】

[Why is the scavenger so arrogant? 】

[The catfish, scientifically known as Silurus sutchus, is native to the Amazon River basin in South America. ]

[It was introduced to China as an ornamental fish in the 80s.]

[In 1990, Guangdong took the lead in introducing catfish from South America. ]

[It was originally chosen for its ability to clean algae, food scraps, and other fish waste from aquariums.]

[Thinking that it could help keep the aquarium clean, I named it "Scavenger." 】

[However, this seemingly "hard-working" cleaner. 】

[Once entering natural waters, its ferocious nature is immediately revealed! ]

[Not only does it not eat garbage, but it specifically eats fish eggs and fry. ]

【Because the climate conditions in southern China are similar to the tropical regions where it originates. 】

[Especially in the Pearl River area, the water temperature and other environmental factors are suitable. ]

[This provides excellent conditions for the survival and reproduction of scavenger fish. ]

[Soon, catfish began to multiply in large numbers in rivers and reservoirs in the south.]

[Not only in Guangdong, but also in rivers in Guangxi, Hainan and other places, their presence has gradually appeared. ]

【Later, the distribution range of the catfish became wider and wider. 】

[It was caught in the Fuchun River in the 20s and appeared in a reservoir in Zhoushan, Zhejiang in 90.]

[Nowadays, their traces can be found in rivers in Hubei, Sichuan, Shanghai and other places. ]

[Even in Yilan, Taiwan, the catfish has multiplied in large numbers and has become a dominant species there.]

[Originally, the scavenger fish was only supposed to be kept as an ornamental fish in aquariums, but now it has settled in the natural waters of southern my country.]

[What’s even more terrifying is that scavengers have almost no natural enemies. ]

[Its body is covered with hard scales, which even large fish find difficult to swallow. ]

[Its stomach can assist in breathing, allowing it to survive for several days out of water.]

[It can live freely in oxygen-deficient stinking ditches, and can even reproduce wildly in severely polluted waters.]

[Its diet is also extremely diverse, and it can be called the "garbage can" of the water. ]

[It feeds not only on algae, but also on small crustaceans and nutrient-rich humus. ]

[They also eat the feces of other fish, and even their eggs.]

[This characteristic of eating everything gives it a great advantage in obtaining food. ]

[When competing with native fish for food resources.]

[Native fish are often no match for it.]

[In some rivers in Guangdong, fishermen cast their nets and caught only scavengers, with native fish almost extinct.]

[In 2022, at the Chengbi River Reservoir in Baise, Guangxi, several people who released animals took a small boat and poured a bag of scavengers into the water, shouting "Everyone who sees it will be blessed." ]

[As a result, this large reservoir of 11.5 billion cubic meters suddenly faced an ecological crisis.]

[In the 2022 Guangxi reservoir incident, the person who released the animals actually said: "I don't know the scavenger, and I don't know it is harmful." 】

[Local ecological experts once expressed despair: "Once the scavengers enter the open water, it is almost impossible to completely remove them."]

Outside the sky.

Warring States Period.

Xunzi, who attached great importance to environmental protection, saw the ignorant man on the sky curtain releasing the scavenger.

My blood pressure instantly rose.

"Even an ancient like me knows that if humans want to obtain better natural resources, they must optimize the environment."

“Later videos also mentioned the importance of protecting the environment many times.”

"But why are there still people so stupid as to release ugly invasive fish species like scavengers into natural waters?"

“Is it because human nature is evil, or is it because human nature is stupid?”

"Anyway, the people who released the scavengers are too stupid. It's annoying just to watch them. Kill them all!"

“Also, why didn’t he stop the person who filmed this sky-high video?”

"Kill them too, kill them all!"

……

The sky continues.

【Why is the scavenger so difficult to deal with? 】

【First of all, the reproductive capacity is amazing. 】

[It lays eggs twice a year, more than 2000 eggs each time. The eggs can hatch in 4 days, and the survival rate is extremely high. ]

【The second is its brutal hunting method. 】【The scavenger fish has an amazing appetite and can eat 3000 to 5000 fish eggs a day. 】

[For native fish species that have weak reproductive capacity and a small number of eggs, this is undoubtedly a disaster.]

[Many native fish populations have suffered drastic declines due to the predation of fish eggs by scavenger fish.]

[They are even facing the danger of extinction.]

[Some small fish that were once common in rivers are now rarely seen.]

[The species diversity of the entire aquatic ecosystem has been greatly damaged because of scavengers.]

[Not only does it eat fish eggs, it also uses its suction cups to attach itself to other fish, causing their death.]

【Then, scavengers may even damage the water ecology. 】

[They chew on water plants, swallow large amounts of algae and other food resources in the water, causing a shortage of food for native fish.]

[It spreads diseases, causes lack of oxygen in water bodies, and turns entire water bodies into dead water.]

[In Donghu Park in Quanzhou, Fujian, staff once caught 400 to 500 kilograms of scavengers mixed with invasive species such as red-eared sliders and crayfish, and the native fish were almost gone.]

[In the Pearl River Basin, scavengers have long been a disaster, and fishermen are even too lazy to catch them. ]

[Because they can neither be eaten nor sold, they are garbage if they are fished out.]

【There is also a hot topic on the Internet. 】

【That is the life force of the scavenger. 】

[There was a video circulating online: a street cleaner was exposed to the sun for 3 days, and then it was "revived" after being watered! ]

[Although experts have clarified that this is just an exaggeration, the scavenger's tolerance is indeed amazing. ]

[Even netizens say: The scavenger fish can’t be killed by the sun or starvation? ]

[In fact, the scavenger can survive out of water because its stomach can assist breathing and it can survive for several hours out of water.]

【With its strong anti-pollution ability, it can be thrown into stinky ditches or industrial wastewater areas. 】

【Still live a comfortable life. 】

[As a fish, it is even resistant to low temperatures! ]

[Although it prefers warm waters, short-term low temperatures will not kill it. ]

[This "invincible cockroach" characteristic makes it a nightmare for freshwater ecosystems. ]

[Even more sadly, scavengers are neither edible nor economically valuable:]

[Because there is little meat and many bones, it is difficult to handle and the edible part is very small. ]

[And bacteria often exceed the standard. ]

[Since scavengers often eat garbage and feces, their bodies contain high levels of parasites and heavy metals. ]

【The key is that it really doesn’t taste good. 】

[The scavenger doesn’t look tasty, and it actually tastes bad. 】

[The meat is so smelly that even the poor Indians eat scavengers with Dubai knife skills. ]

[Therefore, even though the scavengers have become a disaster in some areas of the south, no one is willing to catch them, and they can only let them wreak havoc. ]

[Faced with the serious problem brought about by the invasive species of catfish, relevant departments have taken a series of measures to deal with it. ]

[According to the Criminal Law Amendment, it is clearly stipulated that the illegal release of alien invasive species may be subject to a maximum sentence of three years in prison.]

[In the "Regulations on the Management of Aquatic Biological Propagation and Release" promulgated by the Ministry of Agriculture and Rural Affairs. ]

[It is explicitly prohibited to release aquatic species that do not meet ecological requirements, including the catfish. 】

[Reduce the chances of scavenger fish entering natural waters from the source. ]

[Since 2015, Guangdong fishery management departments have launched several large-scale cleanup operations every year, killing scavenger fish through manual fishing and other methods. ]

【But the task of preventing and controlling scavengers is still arduous. 】

[It can be said that there is still a long way to go. 】

[The ecological crisis caused by scavengers stems from humans’ blind introduction and arbitrary release. ]

[It could have lived safely in the Amazon River, but due to human error, it became a "trash fish" that everyone wanted to kill.]

[When we see someone releasing scavengers, we must resolutely stop them. ]

[Because releasing animals in this way is not a good deed, but a sin. ]

【To protect our aquatic ecology, we need the joint efforts of everyone. 】

The video ends here.

Barrages of comments also appeared one after another.

"This thing is really ugly."

"It gave me goosebumps."

《Ornamental fish? This fish is not ornamental at all!》

"How to deal with the scavengers?"

"Take it to the feed mill and mash it up."

Is it true that street cleaners will never die?

"I used to fish for scavengers. I would throw the fish I caught on the side of the field in the morning, and when I left at night, I found that they were still alive."

"I tested the physical resistance of the street sweeper. I ran it over twice with an electric vehicle, but it was not hurt at all. I took a rubber hammer and hit it dozens of times before it died."

"How cruel! ...The hammer is also life!"

"Why does the scavenger in my fish tank die so easily?"

"I like watching videos of people killing Suneo online the most. It relieves my stress."

"The shell of the scavenger can be made into shoes, scavenger leather shoes!"

"I watched a video. I am a compassionate monk. What's wrong with saving the souls of street cleaners?"

"How was the salvation accomplished? Was it a physical hammer or a magic electric grid?"

"By the way, what does the scavenger taste like?"

"It's edible, but the shell is hard, the meat is very small, and it has a fishy smell. It's difficult to handle, unpalatable, and unsafe."

《I want to eat... hehe.》

"You dare to eat the scavenger, which is almost the periodic table of elements. You are really brave, bro."

……

And outside the sky.

At the end of Ming Dynasty.

Chongzhen stared at the scavenger fish wriggling in the sky and was somewhat interested.

"Tianmu's scavenger fish are very easy to raise and reproduce very quickly."

"They can survive by eating dirt and feces. If they are released into ponds in locust-infested areas, even if they taste bitter, they are better than Guanyin soil."

"Should we, the Ming Dynasty, take the initiative to introduce scavengers?"

"If it works, even if it is fished out of manure, the people will have to swallow it."

"It's better than starving to death."

"In this way, it can be regarded as my efforts for the people, right?" (End of this chapter)
