The gar is an alien species that can infest native fish Why the country has not banned the influx

There are a lot of alien species in China, and the gar is just one of them, and a lot of the alien species are introduced as food, as pets, and so on, because of profits.

At present, species that are overflowing in China and have threatened the water environment include Brazilian turtles, water hyacinths, and so on.

The two examples that I'm going to give you are very familiar with and that you can see everywhere are Brazilian tortoises that have no natural predators in China's freshwater, and they're very ferocious and capable of devouring native Chinese grass tortoises and native Chinese fish stocks.

Water hyacinth was first introduced to improve water quality, but later it was discovered that it began to erupt in a large area every year in a certain season, resulting in a large number of water hyacinth floating on the water surface, hindering the photosynthesis of aquatic plants, lack of oxygen in the water, causing water to deteriorate, stinking, fish began to die, ships could not sail, and so on!

Because as the previous two said, gars are imported into China as pets and are profitable. Why don't piranhas allow gars to be introduced, you ask? Because piranhas have relatively low profit margins, people are stunned when they see them or hear their names, who will raise them or buy them to eat?

Oh, that's far away. The gar has a peculiar appearance and is very profitable as a pet, so the state will treat it like any other alien creature and treat them openly.

Gars are introduced as pets, not bought and released...

Of course, it is an invasive alien species, if it is not for this species to appear in the interior of our country, then it is impossible to cause damage to the environment, and it is impossible to cause pollution to the natural environment. It is unlikely that so many people will be arrested.

The alligator gar is not an invasive species, and there are no breeding records in the wild in China, so it does not meet the definition of an invasive species.

Of course, this alien species will not only damage our environment, but also cause damage to the ecological nature of our country, and will also affect the waters of our country and affect the survival of many animals.

The alligator gar is considered an invasive alien species, so he has no natural predators in the area, which leads to the gradual growth of his team.

Alligator gars are known as killers in the water, they can eat everything they can see, all the creatures that are weaker than them, so they can grow very large without natural predators, and he can lay eggs at one time This is very terrible, so if such a creature is found in the wild area, then it must be reported to the relevant departments and let them destroy this creature, because this is an invasive alien species, which has a very serious destructive power to our local ecology. It can be said that an adult alligator gar, which can reach two meters in length or even longer, in such a situation, it is only a matter of time before they can eat the entire lake for him. So the question is, why do high-risk alien organisms invade China?

Let's talk about this topic for a while. <>

There are a lot of invasive alien species, such as the Fushou snail that we often see, it is an invasive alien species, this snail is extremely destructive, they have few natural enemies, so in such a comfortable environment, they can grow quickly, and lay many eggs at one time. But such creatures will only bring serious damage to the local ecological environment, causing a sharp decline in local species, because competitors appear, they will not have enough to eat, and slowly the population will decrease. This is very unfriendly to every country, just like crayfish, an invasive alien species, we humans find them delicious, so we eat them to be extinct in the wild, and we have to achieve our appetite through artificial breeding.

But there are some invasive alien species that he can't eat at all, such as the Fushou snail, which has a large number of parasites in his body, and even if it is all cooked, there is no guarantee that he can eat it. <>

Most of the invasive alien species are brought back to China by individuals, or experts for cultivation or breeding, and if individuals bring some invasive species back to China, raise them for a period of time, and find that they are not good to raise, they may be thrown into the wild. In general, all invasive alien species are human-induced, because they cannot do it by themselves, or even across the ocean.

An alligator gar can eat the whole lake of fish, and the reason why high-risk alien creatures come to China has a lot to do with the lax supervision of relevant departments.

It may be due to the fact that some residents brought it here, or someone bought the creature abroad and accidentally released it.

Alligator gars come to our country and other countries outside of North and Central America through ornamental fish**. Unfortunately, people usually buy it, raise it, observe it for a while, then lose interest in it, and then abandon it indiscriminately, or release it freely into wild waters. According to local experts, it is possible that the alligator gar found this time was first raised as an ornamental fish and then released in Danzao Xianhu.

Alligator garMainly living in North American waters, it is not difficult to see that the crocodile eel is an invasive species, in fact, crayfish and bullfrogs are also invasive species, and the scientific name of crayfish is crayfish. The meat of crayfish is delicious, rich in protein and metal elements, and has edible value. But even more notorious is the fact that where the crocodile eel was found, other fish species have also become extinct.

The alligator gar is a ferocious predatory fish that attacks if its prey is less than half its length, and the alligator gar can also be an adult alligator gar"Food"。"The alligator gar does not move when it hunts, and until its prey is close enough, it will bite it like a bullet, agile and fast.

In general, an invasion of a species is acceptable if it does not disturb the local ecological balance, but due to the alligator gar's notoriety, it will certainly have a serious impact on the ecological balance. First of all, as we said earlier, the alligator gar is a carnivorous fish that is aggressive and destructive by nature, and it is nothing compared to piranhas. Although the alligator gar has fangs and is not capable of chewing, it can swallow about a quarter of its size at a time, feeding mainly on fish, although it is not picky and will eat any living creature in the water.

It is understood that there are several main reasons why the alligator gar has gone from being an ornamental fish to a bioinvasive species. First of all, this is due to artificial release into the water. At first perhaps due to the novelty of reproduction, but as the appetite grew, the size increased, it became a predator, and it was considered too expensive to reproduce, it was abandoned and released.

Second, during the introduction and development process, it is indeed inevitable that some fish that slip through the net will escape to the natural waters outside due to weather or other uncontrollable factors.

Since the reform and opening up in the 80s, China has been in frequent contact with countries around the world, so since then, the alligator gar has unexpectedly broken into Guangdong, and then it has grown explosively.

It is because it is smuggled that it invades our country, and this animal is particularly rampant in our country, because our country has no natural predators at all.

Some residents of the country bought these fish for stocking because of their curiosity, which led to their invasion.

In fact, we took the initiative to attribute this thing to our China before, because the ecological chain was destroyed at that time, so we wanted to use it to recover, and we didn't choose to breed on a large scale.

The internal organs and eggs of alligator gar are extremely toxic, and if accidentally ingested, it is very likely to cost their own lives, but this fish can be hungry in critical moments, and it must be handled correctly.

The alligator gar is a highly adaptable alien species, which can quickly reproduce for the winter after entering natural waters, and will also have a very negative impact on the local aquatic ecological environment. At the beginning of the introduction of the alligator gar was raised as an ornamental fish, but in the process of breeding, you will also find that the size of the alligator gar continues to increase, the cost of feeding gradually increases, there will be the idea of releasing it, after people in the wild will catch the alligator gar, because of their ignorance will also appear to cook it, but in Guangdong there is a boy who accidentally ate the alligator gar and sent himself to the ICU, which can be seen that this fish is not handled properly in the process of processing, It is very likely that it will affect your normal life.

Alligator gar is best not to eat.

Alligator gar is a carnivorous fish, with strong destructiveness, if released into natural waters, it will cause a great threat to the local aquatic ecological environment, and alligator gar has a very big difference from other ordinary fish, that is, it likes to grow in a dirty environment, and over time it will also cause the flesh of the alligator gar to become very rough, and in the process of growth, a large number of toxins will accumulate in the body, accidentally ingested, which may endanger their own lives.

What is my personal opinion?

I think that the alligator gar in the water, everything is inhabited waters, but also will lead to few other fish can survive, resulting in fishermen's harvest damage, in artificial lakes or other lakes, we found the alligator gar should also be reported to the local authorities in time, so as to strangle the danger in the cradle, for ordinary fish lovers, in the process of raising alligator gar, it is best not to discard or release the idea of wantonly. It is hoped that China can introduce corresponding laws to regulate people's behavior and avoid wanton release and affect environmental safety.

This creature is not edible, and it is highly poisonous among them, and if you are not careful, you may be poisoned.

According to experts, it is best not to try to eat this fish lightly, because its eggs are highly poisonous, so it cannot be ruled out that its flesh will also be poisonous.

This fish is not edible, this fish is aggressive to humans, and we don't know about it, it may be highly poisonous.

The recent news about the alligator gar has attracted much attention, and it has been found in many regions of the country, and it is said that in order to catch the alligator gar, Henan Province even spent a lot of time and energy draining the lake to catch it. The main reason for this is that the alligator gar is too harmful to the ecosystem of the local natural waters. Due to their ferocious temperament and the absence of natural predators in the waters, it will not be long before the number of other fish living in the waters will be greatly reduced.

In the past, people may not have known much about alligator gars, but the recent frequent appearance has made people deeply aware of the dangers of these alien species. In fact, in addition to alligator gars, there are many animals that must not be released at will, such as scavenger fish, which are even known as invincible opponents who eat all over the world, and the reason why they are so called is because they eat almost everything in the water.

Once scavenger fish appear in natural waters, they will eat a large number of eggs of other fish, seriously disrupting the ecological balance of natural waters. What's more, scavenger fish are similar to alligator gars, and have almost no natural predators in natural waters, so it is conceivable that if this fish is released at will, the harm it brings is self-evident. In addition, there is the Brazilian tortoise, which is a common invasive species in life, and many people like to buy a Brazilian tortoise as a small pet.

As everyone knows, if the Brazilian turtle is released at will, it will also cause serious harm to the ecosystem, because their survival ability and reproductive ability are particularly strong, it is easy to break the ecological balance.

In addition, there are bullfrogs, which must not be released at will. Most bullfrogs have a very strong ability to survive, not only will bring extinction to the native frogs, but also all the fish and shrimp living in the pond are not spared, which is also very detrimental to the ecological balance. There are also tilapia, large pencil fish, and fushou snails, all of which cannot be released casually.

Fushou snails, Brazilian tortoises, African giant snails, tilapia, largemouth bass, these animals are not allowed to be released and may be illegal.

For example, animals such as crayfish and catfish cannot be released because they will have a certain impact on the ecological environment.

Destructive animals, animals that can pollute the environment, animals with viruses, animals that pose a risk of infection to the environment, alien species.

The only reason why the alligator gar, an alien species, appears in our country's waters, and that is from artificial release. Some domestic aquarium breeding enthusiasts choose to keep alligator gars as "pets" because of their ornamental properties. When you get tired of it, or when it is difficult to raise a huge alligator gar at home, you will choose to release it.

In this way, the alligator gar came to the waters of our country and wreaked havoc on the ecological environment.

In order to catch the alligator gar in the lake, Ruzhou, Henan Province did not hesitate to spend a month draining all the water in the lake. Such an approach has aroused heated discussions among netizens, and some people feel that whether this method is worth it is not suspected of wasting resources; Some netizens also think that this is a good way, and for the alien species that destroy the ecological environment, we should uphold the attitude of eliminating evil and completely eliminate it.

The alligator gar is an ancient species that has lived on Earth for more than 100 million years. This species did not originally belong to our country, but it was raised as a pet by people who like to breed aquariums, and then introduced to our country, and then because they were released, the alligator gar became an invasive species.

The alligator gar has been found to behave like a fierce enemy, and this is because the alligator gar has a fierce temperament, as long as the water is rich in food, it will continue to grow, and the body length can grow up to 3 meters. This species has no natural predators in domestic water, and can become its food for anything, so it has the ability to seriously damage the ecological environment.

Because of the overflow of kindness of domestic personnel, some foreign creatures have living space and opportunities in our country. The release personnel did not fully understand the species they had released, so they directly released the species into the wild. As everyone knows, they are not doing good deeds, but doing bad deeds, making good intentions become bad intentions.

In the face of our unfamiliar organisms, we must not blindly release, before the release, we need to understand the name of the species, as well as their living habits, so that the release is assured, and the ecological environment will not be damaged due to release.
