For some invasive alien species, it has attracted a lot of attention on the Internet, and there are many enthusiastic species in the water, which will have a certain impact on the living space of some organisms in the body, bring some bad harm to the ecological balance, and may even bring some harm to humans, these invasive alien species not only have alligator gar, but also other species. <>
The invasive species area is for everyone's ecosystem and organisms to survive, due to the introduction of other species to these original organisms caused some harm, so that some of China's deep environment has been affected. It has caused damage to the development of agriculture, forestry, animal husbandry and fishery. There are many kinds of invasive alien species, not all of them are as vicious as the alligator gar, and there are some very inconspicuous fish and shrimp, etc., which may also pose a certain threat to the ecological balance.
In fact, some of the food we eat on the daily table is invasive alien species, which also has some economic value, but if they are released into the wild at will, it will cause great damage. <>
For some alien organisms, there are generally some characteristics, that is, their living environment is very wide, they can survive in many environments, and for some survival resources that cannot be used by other organisms, these alien organisms can be used. These alien creatures are generally relatively small in size, and their life cycle is relatively short, but they reproduce very quickly and spread very quickly. These alien creatures can quickly adapt to the environment when they go to different environments, and survive and reproduce in this place, causing some damage to the local ecosystem.
The crayfish that everyone likes to eat in longevity is actually an invasive alien species, and if the crayfish are put into the wild at will, it is easy to affect the local ecosystem, but now many crayfish have been served on the table and have played some economic roles. For these organisms that are not native to China, it is better not to introduce them easily.

Brazilian turtles and piranhas cannot be released casually, and they will destroy the ecology.
-
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.
-
The Brazilian tortoise, for example, is also an invasive species, and once released into the water column, it eats a variety of native creatures, from invertebrates to fish and frogs.
-
Alien species cannot be released at will. Brazilian tortoises, bullfrogs, large snapping turtles, small snapping turtles, gars, leopard wing catfish, tilapia chile, bluegill sunfish, these species are extremely vigorous, and their impact on environmental resources is very destructive.

Recently, the alligator gar has aroused the attention of many netizens about the invasion of alien species, and the animals that cannot be released at will are; Brazilian tortoise, piranha, gar ,
-
There are snails, Brazilian turtles, piranhas, gars, scavengers, tilapia, mulberry carp, Egyptian pond fish, mosquito fish.

The alligator gar is an exotic species that belongs to the order of gars, the gar family, and the large gars. It is the largest of the seven species of gar in North America and can grow up to 3 meters. The crocodile is a large and ferocious fish that lives mainly in pure freshwater and occasionally in saltwater.
Loved to stay alone. The eggs are poisonous, green in color, and attached to aquatic weeds or gravel. After hatching, the larvae remain hanging on the anchorage.
Edible fish. It is found mainly in the rivers of the Gulf Coast and estuarine waters from Mexico to Florida, the rivers of Lower Missouri and Ohio, and the two lakes of Nicaragua.
1.The alligator gar is an alien species and cannot be released privately. Many people have become a favorite aquarium fish because of their unique appearance.
But due to the fast growth rate of crocodile skin, it can reach a maximum of 3 meters. It is difficult for an ordinary fish tank at home to accommodate such a large and ferocious fish. Moreover, this fish has a large demand for food, so it is difficult for many people to have the motivation to keep it all the time, and then secretly find the waters to release it, without knowing the serious consequences that may be caused.
2.One of the important reasons why alligator gars can quickly appear in many places is that they are easy to buy and sell, the threshold is low, and the release behavior is unscrupulous. Feel free to buy it, and if you don't like it, put it everywhere.
It's all voluntary anyway. No one cared, and no one asked. You can do what you want.
But what these releasers ignore is that when they release crocodiles, they also destroy the lives of other fish and cause damage to the environment.
3.Alligator gars do have natural predators, but they are all American crocodiles, large birds of prey, and otters. It is easy for everyone to find out that its natural enemies are in our country, and there are no them at all.
In fact, many alien species in China have no natural enemies. There is only one reason why they did not spread, and that is that they can be eaten by the Chinese and brought to the table. The crocodile's mouth has a strong survivability and a long lifespan.
It is neither a picky eater, but has a large appetite. After it enters the natural waters, it can be said that all the creatures in the water are on its foraging list, and it is easy to disrupt the natural balance of the waters.
Alligator gars are not good animals, nor are they protected animals, they are harmful to rivers and are not recommended for people to keep them.
-
Alligator gars have no natural predators in China, and if they are found, they should be fished and removed as soon as possible, and they must not be released at will. It is extremely destructive.
-
Because this fish is an alien species, it may damage the ecological environment and cause some impacts on the ecological chain.
-
The alligator gar is a large, ferocious fish that lives mainly in pure freshwater and occasionally in brackish water. Prefer to live alone. The eggs are poisonous, green in color, and adhere to aquatic weeds or gravel.
After hatching, the larvae are still hanging from the holdings. Fish viscera and eggs are highly poisonous. There is no alligator gar in China, which is an invasive alien species and is extremely harmful.
-
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.

As we all know, it is illegal to release alien species in natural waters, but there are always some people who have a fluke mentality and like to challenge the bottom line of the law. There is a man in Guangxi who actually released a scavenger in a reservoir, and he also filmed all the process of his release. As expected, after some netizens found out that the man was released as an alien species scavenger, they condemned him, and the local relevant departments also noticed the incident and finally arrested the man.
I have to say that the man is indeed too ignorant, and the alligator gar incident that occurred not long ago is still vivid, and many people know the harm of alien species to the natural ecological environment. But the man had no idea that what he was doing was wrong, and this time he should have been impressed. Scavengers and alligator gars are also alien species and can be very harmful to natural waters.
If you want to say who has the stronger vitality between the scavenger or the alligator gar, I think it should be the scavenger.
It is said that some netizens filmed a ** about scavengers, exposing them to the sun or leaving the water for a few hours, or even putting them in the refrigerator to freeze, and putting them in water after taking them out, it is likely that they will survive. Moreover, scavengers are very adaptable to the living environment, even if they survive in stinky ditches or harsh conditions, they can still grow and reproduce normally. It is conceivable that the vitality is indeed very tenacious.
Although the alligator gar also has a strong vitality, it is still slightly inferior to the scavenger. Moreover, scavengers may be more harmful to the natural ecological environment than alligator gars. Because scavengers will eat the eggs of other fish everywhere once they appear in natural waters, coupled with their very strong reproductive ability, it will not be long before the number of other fish living in the water will be greatly reduced.
The number of scavengers is increasing, and it is easy to become overwhelmed.
-
Scavengers are tenacious and can survive for a long time even if they are out of water, and they do not have any requirements for water quality, even if the water is dirty, it can survive.
-
The vitality of the scavenger will be stronger, the scavenger is an omnivorous fish, and can adapt well to some environments.
-
The scavenger is more vigorous, and he is also very reproductive, often threatening the living space of some creatures.
-
They breed in large numbers and pose a threat to the local ecological balance. These alien species have no natural predators and will reproduce rapidly after release. They can also have a serious impact on the local ecosystem, disrupting the ecological balance.

The main reason behind the behavior is a lack of cognition combined with the traditional view of behavior.
In itself, scavengers and alligator gars first entered our country's flower and bird market as ornamental farmed fish, which is also the premise for the release of people, and if you want to analyze the reasons for the detailed analysis, I personally think that there are still the following three points.
First of all: the market value of scavengers and alligator gars is low, and there are material conditions for their occurrence.
As ornamental two kinds of fish, scavengers and alligator gar market sales are not high, dozens of yuan or hundreds of yuan can buy fish species of different quality, and the first value of ornamental fish is difficult to be used as the first choice of released species, so such a low market value first laid the objective economic conditions for scavengers and alligator gars to be released, that is to say, many people have such purchasing power.
Second, the lack of awareness leads to a lack of awareness among freers about the ecological damage of scavengers and alligator gars.
In fact, many people are completely unaware of the destructive nature of these two fish to the environment and ecology before the release of scavengers and alligator gars, and once the releasers are discovered, they will immediately be condemned by others or condemned by netizens, and these releasers often cry and say that they do not know, and all the consequences will be borne by themselves, which can only show that these releasers lack the actual cognitive ability of ecology, and they will mistakenly believe that all creatures can coexist peacefully.
In the end: the conventional wisdom has been the driving force behind the release.
Release is only the final result of the behavior, and even if the above two points are satisfied, the ideological motivation can not be ignored at all, this kind of thinking is the traditional accumulation of virtue and good deeds to protect their own thoughts, the act of release is not uncommon in our country, there are freshwater fish to the Yangtze River, there are also turtles, goldfish to the temple, so speaking, the focus of the release of the person's thoughts is only on the release of this matter, and the fish species after the release are not edible in the future, This skewed mindset led them to completely ignore all other factors, which in turn increased the number of scavengers and alligator gars being released.
-
Because these are ornamental fish that many people like to raise, the fish tank can't be put down or they don't want to be raised after they are raised.
-
Many people look at things regardless of the big things and think that they don't want to raise them. As long as it is put back into nature, there are still people who have a revenge mentality.
-
Because people are not aware of the impact of releasing these fish on the ecological environment, they are repeatedly released without realizing the importance.
-
The reasons for the release of alligator gars: pet abandonment, religious release.
1. Pet abandonment
Alligator gar is a common ornamental fish in the market, almost every aquarium that sells tropical fish has alligator gar**, many people buy it, but because the alligator gar grows fast and eats a lot of food, some people cannot afford to continue to raise it when they grow up, so they abandon it to natural waters.
2. Religious release
Many popular religions in China have a culture of animal release, believing that life release is to accumulate virtue and do good, merit is immeasurable, and it will also bring good fortune, so many believers often buy various animals for release, but they do not know the types and hazards of releasing animals.
Hazards of releasing alligator gars
1. The alligator gar is a carnivorous fish, and it is very ferocious and destructive, and will prey on native species, especially fish in waters. Moreover, this alien species lacks natural predators, and the fish in the waters will be eaten, and if there is a shortage of food, the alligator gar will even attack humans.
2. The scales of the alligator gar are very hard, which can resist the sharp blade, it is very difficult to obtain fish meat, and the meat is rough and has no economic value, and the alligator gar will use toxins to protect its eggs from being eaten, so its internal organs and eggs are highly poisonous, which is extremely harmful to other organisms, and cannot be eaten.
Most invasive alien species, such as alligator gars and scavengers, as well as snapping turtles and man-eating pomfret are not suitable for release. >>>More

<> scavenger scavenger fish is also called sucker fish, garbage fish, anglerfish, and is easy to reproduce in large numbers in rivers. Scavenger fish in the aquarium The scavenger fish often attaches to the aquarium wall or aquatic plants to lick moss, so it is the best "scavenger" in the aquarium. Since the scavenger fish is an alien species, there are no natural predators in the country, which will threaten the survival of native fish. >>>More
No teeth. Scavengers are omnivorous fish that feed on algae, benthic animals, and water waste, and large scavenger fish can devour eggs and fry in large quantities. In the aquarium, it is often attached to rocks, glass to stabilize the body and suck algae, and also looks for benthic animals (such as water earthworms), and is a loyal "cleaner" in the aquarium. >>>More
