The Yangtze white sturgeon has been declared extinct, why can t people avoid its extinction even if

First of all, I need to tell you a little bit!

Wei Qiwei, chief scientist of the Yangtze River Fisheries Research Institute of the Chinese Academy of Fishery Sciences, said: There has been no successful case of artificial breeding of the Yangtze white sturgeon. In the past, due to insufficient technology and hardware conditions, the captive-bred Yangtze white sturgeon only survived for a maximum of 29 days, but later all the conditions were met, but we never caught the live Yangtze white sturgeon.

If the Yangtze sturgeon rescue pond had been repaired earlier and with more foresight, and the Yangtze sturgeon would have been raised after it had been caught, there might have been hope for the Yangtze sturgeon. Now we still have a lot of technical reserves, as long as we can still find live Yangtze white sturgeon, there is a glimmer of hope.

Yangtze white sturgeon. The inability to reproduce is the main cause of the extinction of the Yangtze sturgeon. The Yangtze sturgeon usually spawn in the upper reaches of the Yangtze River and forage for fattening in the middle and lower reaches of the Yangtze River, but the construction of the Gezhouba Dam in 1981 cut off their migratory passages, and the juvenile Yangtze sturgeon can still forage through the dam to the middle and lower reaches, but the adult Yangtze sturgeon can no longer return to the upper reaches to spawn.

The second factor is the development of the fishing industry in the Yangtze River, which makes the big fish and small fish all in one net, which directly leads to the death of the Yangtze white sturgeon, or leads to the Yangtze white sturgeon less and less food. This is a key point, because the Yangtze white sturgeon is known as the king of freshwater fish, its body is meters long, and it needs a lot of food every day to survive, and now the Yangtze River has been designated as fish-free!

The third is shipping, the vibration of the machine and ship is very large, there are more and more ships, and the waterways are staggered, not only the propeller of the machine may directly harm the Yangtze River white sturgeon, but also the shipping projects derived from shipping, such as channel improvement, reef blasting, and bank protection, have a great impact on the habitat of the Yangtze white sturgeon.

On January 24, 2003, the Yangtze River Fisheries Research Institute of the Chinese Academy of Fishery Sciences received news that a fisherman in Nanxi, Sichuan Province had caught a Yangtze white sturgeon in the Yangtze River, and Wei Qiwei, the chief scientist of the Institute, immediately led an ambulance team to the local area, and it was confirmed that it was a female Yangtze white sturgeon about 4 meters long and weighing more than 150 kilograms, and there were a large number of fish eggs in its belly.

At that time, the Yangtze white sturgeon was carried around on the fishermen's boat because it was caught by mistake, and it was already seriously injured, its abdomen was all congested, and there were obvious scars on its head and tail. It was sterilized and the wound was sutured, and then placed on a nearby cage fish farm. After a day of rearing, the Yangtze white sturgeon recovered from its injuries and finally decided to release it and install ultrasonic tracking equipment on it.

It was intended to be continuously tracked and monitored, but later the tracking ship ran into a reef and was damaged, and the signal eventually failed. Since then, there have been no reports of sightings of the Yangtze sturgeon in China.

In addition, habitat loss and fragmentation caused by lake reclamation, water pollution, urbanization and aquaculture are all important factors that threaten the survival of the Yangtze white sturgeon.

The extinction of the Yangtze sturgeon is no less serious than the extinction of the giant panda, and it is a heavy blow in the history of Chinese biology!

Artificial breeding may prevent the extinction of the Yangtze sturgeon, but it will do little in some waysOtherwise, how could there still be so many endangered species that have not been solved until now, because in some technical aspects, they are not yet at the level that can save a species.

As a living fossil-like creature in China, the Yangtze white sturgeon has lived with our culture for thousands of years and has witnessed the history of human civilizationBut now the Yangtze River white sturgeon is extinct, and the news of the extinction of the Yangtze River white sturgeon has also attracted the attention of hundreds of millions of us some time ago, which also shows that people are now paying more and more attention to the ecological environment.

And now people are constantly developing new technologies that can allow endangered species to be protected, and corresponding ecological nature reserves will be established, but why is the Yangtze white sturgeon still extinct under so much protection?Or is it because the Yangtze sturgeon has actually been showing signs of extinction very early, and people did not have the technology to breed them in captivity.

The last time the Yangtze sturgeon was found, it was about 2000, when the Yangtze white sturgeon almost did not exist, and there were no more than 1,000 in the world.

But after it was later released into the Yangtze River, no trace of it was foundThis shows that the Yangtze sturgeon may have had an extremely harsh living environment at that time.

It may be because it is difficult for white sturgeon to survive and it is not suitable for captive-bred white sturgeon, so this is the case.

Because their ecological environment requirements are too strict, it is difficult to breed.

This is mainly because China's artificial reproduction technology is not mature enough.

Because there is no way to artificially breed the Yangtze white sturgeon, it is extinct.

The first is illegal fishing, which humans used to catch in large quantities for economic gainYangtze white sturgeon. , and at this time the state has not issued a clearRestraining Orders

Yangtze River Basin. The phenomenon of large-scale fishing by the surrounding residents is one of the direct causes of the extinction of wild white sturgeon.

The second is habitat loss, with dams built in the Yangtze River basin blocking their migration routes, unsustainable sand and gravel mining destroying their spawning grounds, and habitat loss.

There is less hope for the resurrection of the Yangtze sturgeon. The reason for the extinction of the white sturgeon is that it is no longer adapted to today's environment.

The white sturgeon, an ancient species that has survived for more than 100 million years, prefers a cooler environment, and has become extinct due to environmental changes caused by human activities and other factors.

Overhunting by early humans was an important reason for the extinction of the Yangtze sturgeon. In the past, people prioritized food. The Yangtze white sturgeon is deeply loved by consumers because of its large size and delicious taste.

Many local fishermen cater to these consumers in order to survive. , had to catch the Yangtze River white sturgeon.

The reason for the extinction of the Yangtze white sturgeon is because of environmental pollution and poor water quality.

It may be that the environment changes too much, which affects the survival of marine life, and eventually leads to the extinction of species.

Human overfishing has led to a decline in their populations. Various human activities on the Yangtze River have destroyed the habitat of the Yangtze sturgeon, depriving them of the environment on which they depend. The remaining Yangtze sturgeon gradually moved away from human range and could not be detected by humans.

Because the environment of the Yangtze River has changed a lot, and the Yangtze white sturgeon cannot adapt to this change, it will become extinct.

Because of the wanton killing of human beings, there is no end to predation, which will make many animals extinct.

The Yangtze white sturgeon has been officially declared extinct, which is a very sad news environment, and the impact on people is very great. Rivers and freshwater organisms are valuable resources for people, and the continued loss of biodiversity reflects the harshness of the natural environment to a certain extent. According to the relevant regulations, if a species is not capable of reproduction, and the life span of the species has reached the end of the time, and no other individuals are found in the process, then the species is considered extinct.

In 1989, the white sturgeon was already considered a national first-class protected wild animal, and in 1996 it was considered critically endangered, and in 2009, it was re-evaluated that the white sturgeon was in a state of possible extinction. The sturgeon is a very rare fish, the last time it was seen was in 2003 and it has not been seen since. Illegal fishing and dams have blocked the sturgeon's routes, destroyed spawning grounds and lost habitat for bears.

The extinction of one species will inevitably affect the biological chain in nature, and at the same time cause the extinction of other organisms. The relationship between species is very close, and people cannot use an intuitive method to judge that the extinction of species will change the ecosystem a lot, and at the same time, it will also make the ecosystem have the possibility of collapse, and human beings will lose a lot of resources. People can't always ask for things from nature, and the harm done to nature will eventually be returned to humans, so people have to change their behavior.

It is often said that everyone has a responsibility to take care of the environment, but not everyone can take responsibility and put ideas into action. Protecting biodiversity is a vital matter, and people need to be conscientious and need to restrain their behavior. Although the lives of wild animals are far away from people, it is clear from some small details that wild animals are important to people's lives.

People need to learn to respect life, revere nature, do what they can, and save energy and reduce emissions in their lives.

It warns us not to go fishing casually, and we also need to be aware of our responsibility to protect all living things on the earth, the extinction of species is also a hint of the future of mankind, we should not think of ourselves as the king of the food chain.

Tell us that we must protect endangered animals, protect nature, and only by solving the problem at the root can we reap some benefits, and do not litter.

The environment in which we live has changed. Many wild animals are facing extinction. We must protect wild animals, not let them face extinction, and live in harmony with nature to protect our common home.

The Yangtze River white sturgeon was officially declared extinct, and seeing the news made many netizens feel sorry. After the Yangtze sturgeon was officially declared extinct, what warnings did it bring to people? There are three warnings about this incident:

The first point is to create a good ecological environment, the second point is to protect the ecological balance, and the third point is that the state must vigorously publicize and raise the awareness of protecting wild animals.

1. Create a good ecological environment. In fact, a good ecological environment needs to be maintained by everyone, not only a small number of people, so that the ecological balance cannot achieve a real balance. Because just like most people are maintaining the ecological balance, but a small number of people will destroy the balance and destroy far more than the area that people want to maintain.

In this case, it is easy to make it impossible to complete a good ecological environment. Especially like China's four major environmental pollution, if it continues to continue, if it is not effectively controlled or solved, then more and more species will be on the verge of extinction or extinction in the later stage, when the food chain is broken, in fact, it is not only the organisms themselves but also human beings.

2. Protect the ecological balance. In fact, ecological balance is a constant condition, and it is also a natural law. Nature itself pays attention to the law of the jungle, which no animal can escape.

In fact, for human beings, it is also an animal, if a certain animal chain is forcibly destroyed, then it will lead to the imbalance of the entire ecological chain, and finally threaten itself.

3. Vigorously promote the awareness of wild protected animals. In fact, from the relevant data and people's perception of wild animals, China's awareness of wildlife protection is not very high, and the publicity is not very large. In fact, now that the ** continues to develop, you will find that many people have found some rare animals, but they don't know how many levels of protected animals this is, or even whether they are protected animals?

Therefore, the state can carry out 1 or 2 wildlife protection publicity and their first display every year, so that people can learn more about wild animals, and at the same time, people can also recognize them.

The Yangtze sturgeon has been officially declared extinct, and the warning is that it is urgent to protect endangered animals, otherwise there will be fewer and fewer animals in the world, and in the end there will be incalculable consequences.

The extinction of the Yangtze sturgeon was caused by overfishing and habitat destruction.

The functional extinction of the Yangtze sturgeon, and humans bear the greatest responsibility. First, human overfishing has led to a decline in their populations. Second, human activities on the Yangtze River, such as sand mining, dam construction, and ship navigation, will destroy the habitat of the Yangtze sturgeon, depriving them of the environment in which they depend.

The story of the Yangtze white sturgeon:

Standing at the top of the Yangtze food chain, the Yangtze white sturgeon can reach 7 to 8 meters in length and weigh hundreds of kilograms. The Yangtze white sturgeon was once very popular. As early as the 70s of the last century, the Yangtze white sturgeon was caught in large quantities as a food fish.

By 1983, the Yangtze white sturgeon, whose population had declined dramatically, was listed as a protected animal and their fishing was banned. Even though people no longer fish for the Yangtze sturgeon, due to the continuous destruction of the ecological environment, by the end of the last century, the number of Yangtze white sturgeon has plummeted, and only a few hundred remain.

In 2002, a Yangtze white sturgeon was caught. In early 2003, scientists released him. However, what they never expected was that this would be the last time people would see a live Yangtze white sturgeon.

Since then, the search for the Yangtze white sturgeon has yielded nothing, and fears have begun that this extremely rare species is on the verge of extinction.
