On November 14, 1976, a bus departed from Manaus and was traveling through the Brazilian jungle. After driving fatigue for several days in a row, the driver felt very tired, so the tragedy happened.
A bus of people rushed directly into the Brazilian Amazon River. The most terrifying thing was that piranhas in the river rushed directly into the bus and ate almost everyone. It is said that only one person escaped through an open window of the bus.
Most of a day later, when the bus was dragged up from the river, people found that all the corpses had been eaten horribly, and some passengers even had only bones left.
Piranhas and other carnivorous fish are generally found in the freshwater of the Amazon River Basin in South America and are rarely seen in other parts of the world.
However, with the expansion of human footprints, many ferocious fish in American watersheds have been taken away from their original living environments and moved to other waters around the world. Little do they know that there is a huge crisis hidden here.
A few days ago, about 200,000 to 300,000 cubic meters of lake water was drained from the Central Park in Ruzhou, Henan, just to salvage a fish: crocodile gar!
According to eyewitnesses, this fish is a "large fish monster" that looks very similar to a crocodile. Don't underestimate this fish. It is not our local fish, but an invasive species. Like piranhas, it comes from across the Pacific Ocean. of the American continent.
Many people don’t understand why it costs so much to catch this fish. In fact, the reason is very simple: safety.
First, the dangers of native waters.
The crocodile gar is a type of gar. Because the crocodile gar is covered with hard scales and has a long mouth full of sharp teeth, it is indeed somewhat similar to the crocodile . is a ferocious fish.
It traveled across the ocean as " ornamental fish " and came to other countries other than my country and its place of origin.
A crocodile gar fry of a few centimeters costs about ten yuan online. Many people buy it home and raise it. After a period of time, they lose interest and abandon it or release it in the wild.
This is why in recent years, fishermen and wild fishing enthusiasts often find alligator gar.
What they don't know is that behind this small action of releasing animals, there is actually a huge crisis hidden.
The alligator gar has sharp teeth and is highly aggressive. Even in the waters of the Americas, it is at the top of the food chain. This "freshwater killer" has no natural enemies in our country's waters for the time being. Its existence will bring fatal harm to all fish existing in the waters.
A fisherman from Chaoshan once discovered an alligator gar in his own fish pond. The fish in the entire pond were basically wiped out, and other freshwater fish became its food. It was really overbearing! To this day, it is still an “enemy” that fishermen strictly guard against.
Therefore, once this kind of killer enters an unfamiliar open water area in the wild, it can easily cause devastating damage to the local native waters and seriously damage the entire ecological balance.
Second, crocodile gar not only attack fish, but also humans.
The crocodile gar is a large omnivorous fish that eats anything and is very easy to feed. It is generally 1 to 2 meters in length. The largest adult crocodile gar can grow to about 3 meters, and it is also the largest among gars.
Their bodies are very long, cylindrical, blue-gray in color with dark black markings, their mouths are relatively wide, and they look ferocious, making them extremely difficult for humans to capture.
They like to live in fresh water and feed on freshwater fish. When hunting, they always swim slowly, like a stick floating in the water. When the time is right, they rush over quickly and open their long mouths with sharp teeth. , capture prey.
They have super swallowing abilities and can swallow creatures larger than themselves, even comparable to snakes.
The crocodile gar is a carnivore and may eat humans if attacked by humans. It has been rated as one of the ten most ferocious freshwater fish in the world.
In the river basins where it is mainly distributed, incidents of fish injuring people often occur, and the murderer is the crocodile gar. Especially during its spawning period, if someone messes with it, it will attack humans after being frightened.
Third, poisonous.
The gar is a taxonomically classified species of the family Gar. A 120-million-year-old Cretaceous gar fossil has been discovered in Europe. Therefore, it is also known as the "living fossil" among fish.
If an ordinary species can survive for such a long time, everyone knows that it is definitely not a kind species. In addition to its extremely ferocious attack power, it is also related to its poisonous nature.
The fish eggs laid by crocodile gar contain highly toxic and are green in color. They usually adhere to aquatic plants or gravel. If people eat it by mistake, it will be poisoned and even life-threatening. If you are a human being, just imagine if you can survive if you eat other fish?
In addition, some of its internal organs are also poisonous . Humans can only eat a small amount of meat from its back, and the gar meat is said to not taste very good.
If is during the ovulation period of , the risk of poisoning will be increased. Therefore, its risk of being predated is also greatly reduced. Attributes like
are destined to have too few enemies, and even humans can't do anything about it.
Such a ferocious and poisonous fish can really be said to be at the top of the fish pyramid, but there is one thing it is also afraid of, and that is the charged electric eel.
The electric eel can launch multiple electric shocks in one second. Even if it is as ferocious as a crocodile gar, it cannot resist it and can only run away.
Nature has its own laws of elimination. Creatures that have adapted to one ecological environment will enter another ecological chain at will. Sometimes it is not a new life, but may be destruction and destruction. Such destructiveness may not be repaired for a long time.
Therefore, I would like to remind all friends who love fish farming, not to release or discard invasive alien species at will, especially the ferocious species at the top of the food chain.
It is possible that what you think is a good deed a day and a happy deed will bring disaster to the local " fish and health people".
An unintentional move on your part may bring huge butterfly effect to and .
hopes that the warning brought by the "Alligator Gar" incident can be seen by more people and alert more people to . In addition, it is also hoped that relevant management departments can strengthen and standardize the management of exotic ornamental fish.
