After 10 years of banning fishing in the Yangtze River, can white sided dolphins still appear? How l

10 years after the ban on fishing in the Yangtze RiverWhite-sided dolphins may still appear, but the chances of population recovery are relatively smallBecause for such a situation, in fact, everyone can see that the Yangtze River white-sided dolphin is actually on the verge of extinction, but now there may be many scientists who think that there are still white-sided dolphins, but the number may be relatively small, and they do not live in the Yangtze River basin, but for such a situation, in fact, each of us feels unacceptable, because each of us is wrong and negligent to cause their genocide. If it's because of us humans, wait for us humans to become a member of the ** food. If the extinction of human beings is caused by other work, it is also a disguised punishment?

I don't really care about things like this, but there are some animal lovers or animal protectors who actually think that such things are our responsibility, but it is true that this matter is ultimately our problem. If we don't hunt or catch them on a large scale, then I won't have such a problem, for such a situation, in fact, it does not mean that it can be produced overnight, but the evolution of the situation over a long period of time can only show that each of us, this protection of nature is not enough.

Most people may have this feeling or this kind of thinking, but each of us should also go to such a thing, is we not good enough, I am doing well, we need to change, including now we have an attitude towards animals, sometimes we may feel that there is nothing, but really think about it yourself, in fact, this kind of thing is different for each of us, most of the time we take it seriously, And for animals, I don't think of them as our friends, it's not like enemies, and we can't treat them as eaters, and each of us has a responsibility to protect them.

Although it may be more difficult to protect them, as long as we are attentive enough, as long as we work hard enough, to do such a thing, in fact, it is not difficult, in the face of such a situation, each of us can do the same, for such a situation, in fact, most people should take it seriously, it is how each of us to take it seriously, of course, we may have a lot of problems and a lot of mistakes, It's just that if we can repent again, then these things may be changed for me after 10 years of banning fishing in the Yangtze RiverWhite-sided dolphins may still appear, but the chances of population recovery are relatively small

The white-sided dolphin has become extinct, and scientists declared it functionally extinct when the captive white-sided dolphin from the Wuhan Research Institute died of aging in 2002.

The white-sided dolphin in the Yangtze River is at the top of the food chain and has no natural predators, so its disappearance cannot be caused by natural causes, but in fact, it is human activities such as overfishing, water transportation, and pollutant discharge that cause the disappearance of the white-sided dolphin. More than 90% of the white-sided dolphin specimens collected over the years were directly caused by human activities.

Causes of the extinction of the white-sided dolphin:

The endangerment of the white-sided dolphin is partly due to internal reasons, and the other part is the external cause of the human environment, the first internal reason is that the white-sided dolphin has a long reproductive cycle, they can live up to 30 years, so they are sexually mature at the age of six, and the total number of white-sided dolphins is not much, so the inability to reproduce in large numbers has become an important reason for the extinction of the white-sided dolphin.

The 2017 finless porpoise conservation team spent 30 days searching for information about the finless porpoise and investigating the white-sided dolphin, but it is said that they have never seen one in ten years, and this one in 2018 brought hope to countless volunteers.

I think it is possible to recover, because now that the ecological environment has improved, their number has begun to increase gradually, so there is a possibility of restoration.

I guess it's right!! It's a pity!!

In January 1980, fishermen in Jiayu County, Hubei Province, caught the world's first live male baiji dolphin on the Yangtze River near the mouth of Dongting Lake, and he was immediately sent to the Institute of Hydrobiology of the Chinese Academy of Sciences in Wuhan, Hubei Province, to raise in captivity. On July 14, 2002, the baiji dolphin died. A female cub was captured in 1986 and died of pneumonia two and a half years later.

In 1995, a sexually mature female white-sided dolphin was caught in the Shishou River section of Hubei Province and stocked in the Yangtze River Ancient Road White-sided Dolphin Nature Reserve in Shishou Tianezhou. In the summer of 1996, the Yangtze River flooded, and the white-sided dolphin died after touching the net.

November 6, 2006 On December 13, 2006, nearly 40 scientists from China, the United States, the United Kingdom, Japan, Germany and Switzerland investigated the 1,700-kilometer section of the main stream of the middle and lower reaches of the Yangtze River from Yichang to Shanghai, and did not find a single baiji dolphin. From 1997 to 1999, the Ministry of Agriculture organized large-scale monitoring operations for three consecutive years, and found 13, 4 and 4 baiji dolphins in three consecutive years. The result of this expedition was 0.

1979: China declared the baiji dolphin an endangered species.

1983: Legislation made it illegal to hunt baiji dolphins.

1986: 300 heads remaining 1990: 200 heads remaining.

1997: less than 50 (23 found).

1998: Only 7 were found.

2004: In July, the stranded and dead body of the Baiji dolphin was found in the Nanjing section of the Yangtze River.

2006: almost 0 heads.

2007: The Yangtze River Baiji dolphin was officially declared extinct on August 8.

Not ...... though2007: On August 19, a citizen in Tongling, Anhui Province, stumbled upon a Baiji dolphin in the river section of the Tongling Freshwater Dolphin National Nature Reserve and photographed it with a digital camera.

In 2007, the white-sided dolphin was declared functionally extinct, and even faced the possibility of extinction, but in 2017, the white-sided dolphin that had disappeared for 10 years reappeared in the Yangtze River area, which attracted great attention from the world, but it remains to be verified whether it is a real white-sided dolphin.

The white-sided dolphin, also known as the white-sided whale, white-sided dolphin, white flag, white clip, blue-finned dolphin, Jiangma, Chinese finless porpoise, Yangtze finless porpoise and Yangtze river pufferfish, is an endemic freshwater cetacean in China, which is only produced in the middle and lower reaches of the Yangtze River. In the 80s of the 20th century, due to various reasons, the population of white-sided dolphins plummeted, and in 2002 it was estimated that there were less than 50 individuals, and they were known as "giant pandas in the water". The white-sided dolphin is a family of its own, listed as a national first-class wild protected animal, and one of the 12 most endangered animals in the world.

Fifty years ago, white-sided dolphins could still be seen in groups on the Yangtze River, but now, not even a single white-sided dolphin can be found. Since the death of the last captive-bred white-sided dolphin in 2002, no real white-sided dolphin has been seen. On August 8, 2007, a report was published in the journal "Royal Society Bioletterhead", officially announcing the functional extinction of the white-sided dolphin.

The so-called functional extinction is due to the destruction of the living environment, the number is very scarce, resulting in the basic loss of the ability to maintain reproduction in the natural state, and even the loss of the ability to maintain survival, if not rescued in time, it may be completely extinct.
