Why are alligator gars afraid of blackfish, and why are alligator gars afraid of guppies?

The official name of the blackfish is snakehead.

It is widely distributed in China from Heilongjiang to the Pearl River and Hainan Island.

Water system. The snakehead is a very ferocious carnivorous fish, with the same rough skin and thick flesh as the gar, and is not afraid of lack of oxygen, but its maximum body length is only about one meter, while the alligator gar is not afraid of hypoxia.

The body length can exceed three meters. From this point of view, it seems that the snakehead can only kneel and call Daddy when it encounters the gar? However, like other snakeheads, they have a short temper and are extremely aggressive towards fish of the same size.

In other words, if two fish of similar size are together, the snakehead may be more ferocious.

A lukewarm piece of knowledge is that the alligator gar invaded China, where the snakehead originated, and the snakehead also invaded North America, where the alligator gar originated—and it is more deeply rooted and more widely distributed, and the local people in North America hate it and are not clean, and it is still unclear when it was introduced. Although physically inferior to alligator gars, snakeheads have extremely rapid sexual maturity, as they are known locally"Northern snakehead.

The fish reach sexual maturity within two years, and the broodstock will take care of them until they reach a body length of 4-5 cm – at which point they are already extremely capable of devouring. Such a high reproduction rate and high survival rate are like hanging compared to the 10-14 years before the gar becomes sexually mature, and the gar has no idea how many rounds of regeneration it has taken in a generation, and its population can snowball in the absence of natural predators.

Grow and grow. In the matter of invasion, the most important thing is overall competitiveness rather than combat effectiveness, and sometimes the invasion of apex predators does not have much advantage because they are too demanding on resources and space. Bosten Lake, Xinjiang.

The apex predator, the barramundi, is squeezed out of the lake by the tiny perch, but this is mainly due to the fishing of the barramundi and the fact that too many perch eat the larvae of the barramundi. In terms of reproduction rate, the vicious-looking alligator gar has basically no advantage other than the poisonous eggs.

Young alligator gars are afraid of snakeheads. Snakehead fish, also known as black fish, is a kind of fish that is very harmful to the natural ecological environment, this kind of fish is fierce, fecundity, appetite is particularly good, and can also eat all other fish in a certain water. The most terrifying thing is that this black fish can glide on land, move to other waters in search of food, and can live in the water for up to three days, and if it weren't for its size, I think humans would be under their poisonous hands.

Young alligator gars are therefore afraid of snakeheads.

Alligator gars are not afraid of blackfish, because alligator gars are very fierce, and blackfish can't kill alligator gars.

Alligator gars are not afraid of guppies, alligator gars can reach several meters in length, and can eat hundreds of guppies in one bite, so alligator gars are not afraid of guppies. The alligator gar has a long lifespan, can live for more than 25 years, and is a hard-lived freshwater fish. Guppies are small, omnivorous species.

They are very resilient to the environment, and are distributed in the lower reaches of rivers, lakes and marshes and ditches in some tropical areas, and their wild habitats are diversified, mainly inhabiting freshwater basins and lakes and marshes.

<> "How scary is the alligator gar?

Monsters in the lake. It all started a month ago, when residents of Ruzhou, Henan Province, photographed a strange large fish wrapped in hard scales and a large, long mouth in Yunchan Lake in mid-July.

Big fish in North America. Native to North America, the alligator gar is named after the alligator gar because of its iconic large mouth resembling a crocodile and a subspecies of the gar family. This large fish has been on Earth for nearly 100 million years and is a living fossil.

But the alligator gar is not as precious as other living fossil species, and it is a rather dangerous invasive species. If you want to say why the whole country is searching for alligator gars everywhere like arresting wanted criminals, it is because the damage to the ecological environment is too bad. Zhuzhou is blind.

Prevention is better than cure. Unfortunately, if the alligator gar does flood our waters, we have no good way to use it, at most we can kill the alligator gar as much as possible, but this is only a palliative solution.

Therefore, it is important to stifle the alligator gar at the source before it is completely overflowing. So, how did the alligator gar, which is native to North America, come to China?

At present, the more reliable theory is that the alligator gar was introduced into China as an ornamental fish, this strange fish is fierce in appearance, lively and active, and has been welcomed by many ornamental fish lovers in China in recent years.

There is nothing wrong with keeping alligator gars in fish tanks, but a small number of irresponsible fish farmers will discard them in nearby waters after they are tired of them, and the surviving alligator gars have invaded our ecology.

The alligator gar is rated as one of the top 10 most ferocious freshwater fish in the world, and the fierceness of the alligator gar can be heard by calling this nameless name, the alligator gar is the largest of the seven species of gar in North America, and can grow up to 3 meters. It is mainly found in the waters of rivers and estuaries along the Gulf Coast from Mexico to Florida, the lower reaches of the Missouri and Ohio rivers, and two lakes in Nicaragua.

So in these waters, there are occasional things that happen when some ferocious fish hurt people, which is the alligator gar. After all, the alligator gar is a carnivorous fish that is extremely destructive, and if it is released into natural waters, it will bring disaster to the local water ecosystem, "as long as it is a living creature in the water, it will eat almost everything". Moreover, its eggs are highly poisonous.

If a person provokes it, or if it is frightened, it will attack the human.

The alligator gar is a gar fish and is the largest of its kind. Don't think that the name is similar to that of an eel, in fact, the alligator gar has a crocodile, and its ferocity is no less than that of a crocodile. The alligator gar is one of the most fearsome freshwater fish, growing up to three meters tall and threatening to attack people.

Alligator gars are carnivores, and if they are attacked by humans, they may eat humans, but they generally do not actively attack humans. Alligator gars generally swallow a quarter of their own food in one bite, and the size of humans is generally not the target of alligator gars, so many rumors that alligator gars are similar to sharks are inaccurate, and there is no phenomenon of alligator gars eating people.

Because the alligator gar is an invasive alien species, once released into natural waters, it will bring disaster to the ecosystem of the water body.

The alligator gar is an extremely dangerous invasive alien species, and the harm it may bring is mainly to destroy the original ecological balance. Not only does it eat everything, but the green fish eggs it lays are also highly toxic, but it is also tenacious, can live for more than 25 years, and is not picky about water quality, whether it is fresh water or saltwater ecology, it can also breathe air, and can still persist for at least two hours without dying when leaving the water.

As a result, they have now been included in the list of "invasive alien species" by many countries in the world, and their introduction and cultivation are strictly regulated, and they are prohibited from entering the natural environment where they are not originated. After this "killer" fish came to China, it temporarily had no natural predators in China's waters.

A basic introduction to alligator gars

Alligator gars are taxonomically belonging to the gar family. It is an ancient fish, and fossils of Cretaceous gars have been found in Europe for hundreds of millions of years, when gars were widely found in almost all the world's waters. For this reason, gars are also known as "living fossils" among fish.

However, only the alligator gar and six other species of gar remain in this ancient fish, and their distribution range is limited to eastern and central America.

The alligator gar is a large carnivorous freshwater fish, the largest of the seven species of gar, which can grow up to 3 meters and weigh more than 90 kilograms. The alligator gar is covered with hard scales, has a long upper and lower jaw, and has sharp fangs, which are said to have more teeth than crocodiles, and are also sharper, so some people call it "sharp-billed crocodile" or "rocket fish".

The alligator gar is a type of gar.

It belongs to the genus of gars of the gar family, but the alligator gar is relatively large, and its body length can reach about 3 meters after adulthood.

Wild-grown alligator gars mainly live in freshwater, and even oaks enter saltwater and are more adaptable to water quality.

They are usually dark green or olive green in color, with grayish-white sides of the back and some parts of the belly that will be pink.

This fish belongs to exotic creatures, some are known as killers in the water, and have no natural predators. Alligator gar, a carnivorous fish, is highly destructive and has a very complex diet. As long as it is a creature that lives in water, it can be its food.

This is a large number of species, which will not only damage the ecology, but also lead to a rapid decline in the total number of freshwater fish, which needs to be hunted in time.
