"Smile Angel" is in the same frame with Huanghelou!

We have reason to believe

Porpherfins love Wuhan deeply

Just like Wuhan deeply loves porpoons

Porpherp and Yellow Crane Tower perfectly "same frame"

"Oh, look at it, it's a porpoise!"

In recent years, the figure of porpoons can often be seen in the Wuhan section of the Yangtze River, and the porpoise even has a rare "same frame" with the Yellow Crane Tower.

Since 2022, the Wuhan section of the Yangtze River has been discovered many times in the Wuhan section of the Yangtze River. It has appeared three times in March alone.

October 21, 2018

At 14 o'clock, more than ten porpoons appeared near the river near the Erqi Yangtze River Bridge. After staying for an hour, swimming up.

August 2020

Some citizens took more than a dozen dolphins to jump in the Wujin embankment section of Wuhan Bridge in Wuhan.

September 17, 2020

On the same day, Jiangtian was hazy and rare. On the upper reaches of the Wuhan Yangtze River Bridge, a group of dolphins jumped in the rain.

There are about 200 meters from the shore in the porpoise water, and the number is 4 to 6 heads. There is a pair of mother and child dolphins, one, one, and one small, and follow. This is the first time that the porpoise has appeared in the center of Wuhan in recent years.

October 26, 2022

At 18:30, after more than a month of squatting, the reporter Bao Gaoyan, a reporter from the Yangtze River Daily, took a video of 5 dolphins in the Baishazhou waters in Wuhan, Yangtze River, and the picture was very clear.

Wang Kexiong, a researcher at the Institute of Aquatic Institute of Chinese Academy of Sciences, said after watching the video that this video is the highest -definition picture of the porpoons in Wuhan section, which is very precious. "It can be seen in the video that the porpoise is out of water, the posture is complete, and the image is clear. It has high scientific value for the number of porphor population in the Wuhan section, the water distribution, and the habits of the living habits."

March 11, 2022

Some citizens took the porpoise in the Xinzhou section of the Yangtze River.

March 23, 2022

At 9 am, the Jiangxia Jinshui River estuary, and the fishing administration law enforcement staff was surprised to find that there was a group of porpoons flipped back and jumped on the sparkling river surface to catch up with the prey on small fish and shrimp. The staff introduced that after the "ten years forbidden fishing", they met porch twice in the same waters, but the first time in groups were still the first time.

Cao Wenxuan, an academician of the Chinese Academy of Sciences, who advocated the "ten -year -old fishing forbidden fishing" in the Yangtze River, also said that since the "ten years of fishing for fishing" in the Yangtze River, the porpoons who have eaten fish have frequently appeared in the Wuhan River surface of the Yangtze River, indicating that the ecological environment of the Yangtze River has continued to improve.

March 25, 2022

From 11:00 to 14:00, Wuhan used the fishery administration Tianwang information system to continue to take the porpoise surface at the East Jinghekou of the Yangtze River. It was initially judged that there were about 4 to 5 heads in this population.

Wang Kexiong, a researcher at the Institute of Aquatic Institute of Chinese Academy of Sciences, introduced that in 2006, 2012, and 2017, the three large -scale Yangtian dolphin scientific examinations were not observed in the Wuhan River section. However, since 2020, with the in -depth advancement of the ban on arrest of the Yangtze River Basin, the aquatic ecological environment and fishery resources of the Wuhan section of the Yangtze River have become better. "Playlintes of a family of three in porpoises" have become the topic of citizens' competition. Many citizens stop on both sides of Baishazhou and Parrot. 02

Foraging and strolling

They may come from the upstream to eat fish

In the Wuhan section of the Yangtze River frequently, porpoons are frequently showed. First of all, due to the improvement of the environment after the ban on the Yangtze River, there are more fish in the river. In addition, the rising water during the flood season expands the porch's migration space.

The porpoise has the habit of migration, and the scope of migration of scientific research is 25-90 kilometers. About 80 kilometers from the upper reaches of the Wuhan Yangtze River Bridge, it is the National Nature Reserve of the newly snail section of the Yangtze River in Hubei. There is a Jiang Xinzhou named Tuanzhou in the reserved area. It is opposite the Bayzhou Bay. It has been inhabited 8-10 dolphin population for many years.

"The porpoons seen in the Wuhan section of the Yangtze River may come from the upstream to eat fish. The porpoise is a barometer of ecological health of the Mother River of the Yangtze River. Seeing the Yangtze River in the river in the middle of the river, it can make Wuhan citizens truly feel the Yangtze River more. The results of great protection. "Wang Kexiong said.

F9c22 is born

The world's first "live" porpoons childbirth

Over the years, porpoons and Wuhan have inextricable connections, which has deep feelings.

On July 5, 2005, in Wuhan Baiyu Pochon Pavilion, the porpoise "Taotao" was born! It is the first porch that was born in the artificial environment, and it is also the first porch that has survived for more than 10 years in the world. It has created a scientific record for artificial breeding and breeding porpoons. This year, Taotao is 17 years old.

In 2019, Tao Tao and a mother dolphin gave birth to female dolphins code -named F9C. Unfortunately, the F9C died of illness when he was 4 months old. On June 3, 2020, Tao Tao's love crystals and mother dolphins were born, and the male porpoons codenamed YYC were born, marking the successful survival of the second generation of porpoons born in the artificial environment. Tao Tao can grow up healthy and successfully breed the second generation, allowing people to see the fate of the endangered species of porpoons, the last mammal of the Yangtze River section.

On July 6, 2022, the Institute of Aquatic Institute of Aquatic Academy of Sciences first released the surveillance video of the new baby's new baby. This is the first time to the world for the first time in the Yangtze Rolfin delivery process. Ten million netizens have witnessed the sacred moment of "National Treasure Timing Ding".

The new porpoise is called F9C22, which is a female porpoise, which brings new hope to the artificial breeding group of the Yangtze River.

What is the significance of the world's first porch "Timing" live broadcast?

Wang Kexiong, a researcher at the Institute of Aquatic Institute of Chinese Academy of Sciences, explained that "Queen is a national first -class protection of wildlife. This time, the surveillance video of the entire process of peak delivery in the Institute of Aquatic Institute of Aquatic Institute of Aquatic Institute of Aquatic Institute can not only intuitively understand the whole process of the breeding and growth of porphyols, but also do its best It may be possible to reduce the impact of artificial interference in the process of breeding of porpoons, so that the public can better understand, care and protect porpoons, and jointly protect the habitat of porpoons, so that the porpoons become the 'frequent visitor' in the Wuhan section of the Yangtze River. "

Hao Yujiang, an associate researcher at the Institute of Aquatic Biology of the Chinese Academy of Sciences, introduced that artificial breeding is one of the important ways for porpoons to protect. At present, the main measures of porpoons' protection include local protection, relocation protection, and artificial breeding. Local protection is the fundamental goal. Migration protection is an important component. Artificial breeding is mainly to provide technical support for local protection and relocation protection. By raising porpoons in the artificial environment, understanding the growth and breeding and environmental needs of porpoons, and providing guidance for local protection and relocation protection.

The smooth production of the porpoch this time is inseparable from the long -term understanding and research on the rules of porpoons breeding. The next step is to strengthen the study of the system mechanism of porpoons breeding survival. Especially the F9C22 born this time is a female baby, which also brings new vitality to the breeding of porpoons.

Pretellasia is naturally a "smile angel"

The porpoise is a small dental whale mammal of the genus Rippochemical family, including the three subspecies of East Asian porch porpoise, Indian porpoise and the Yangtze River porpoise. Among them, East Asia's dolphins are mainly distributed in the Yellow River, East my country Sea, Bohai Sea, and Japan Sea. Indian Pills are mainly distributed in waters from the Taiwan Strait and the South China Sea to the Indian Ocean. Only N. A. Asiaeorientalis (N. A. Asiaeorientalis), living in the large river of land, is the only rat dolphin living in freshwater in the world.

According to the "Chinese Animals", the porpoons of the Yangtze River were settled from the long ocean to the last ice period of 10,000 to 20,000 years ago.

For a long time, they are one of the most prosperous species in the Yangtze River. No wonder Han Yu will write a very angry sentence in "Yueyang Tower Bie Si Zhi" in "Yueyang Tower". Unlike the White Cycles and Chinese White Dolphin, the porpoise of the Yangtze River is short and wide, without the dorsal fins, and the whole body is lead -gray or gray -white. Because of long -term living in relatively turbid fresh water, the eyes of the Yangtze River porpoise are very small, but they have the iconic rising arc mouth shape, which also gives them the name of "smile angel".

In terms of life, the Yangtze Rolls in the Yangtze River are eaten with small fish such as dining fish and blue -scale fish. They can adapt to the water temperature in the range of 4 ° C to 20 ° C, and the vitality is very tenacious.

However, it is such a tough and cute creature that faced the crisis of survival. In the 1970s, as human production activities such as shipping and fishing continued to intensify, the environment in some areas of the Yangtze River Basin deteriorated sharply, and it also brought a fatal blow to many aquatic creatures living here. According to statistics, the number of porpoons in the Yangtze River decreased from 2700 heads in the early 1990s to only 1012 heads in 2017. In 2013, the Yangtzepin was listed as an extremely endangered species by the International Nature Conservation Alliance (IUCN).

Wuhan is one of the important habitats of porpoons

The length of the length of the world and the first (6300 kilometers) in Asia, the Yangtze River with an area of ​​about 1.8 million square kilometers, not only nurtured nearly one -third of the country's population, but also one of the most concentrated areas of my country's biodiversity.

According to statistics, there are about 424 types of fish in the Yangtze River, of which 183 are unique. As the species and umbrella species of the health system of the Yangtze River Tamsui ecosystem, the growth of the Yangtze River porpoise is one of the important criteria for evaluating water quality and aquatic biological diversity.

The pepper of the Yangtze River is mainly inhabited in the middle and lower reaches of the Yangtze River, and the two large and lakes, Poyang Lake and Dongting Lake. At present, nine porpoons have established nine porpoons along the Yangtze River to provide the Yangtze River porpoons with labor breeding, local protection and relocation protection for the Yangtze River.

Wuhan, which has the five large rivers of the Yangtze River, Hanshui, Water River, Laoshui River, and Langshui River in the territory, has also become one of the important habitats that like the Yangtze River porpoons who like to move at the junction of Jiangzhou. Wuhan is the Yangtze River hub, where the Han River is merged into the Yangtze River, it is Dongting Lake to the west, and the east is Poyang Lake.

The Institute of Aquatic Biological Research, which has long been committed to the study and protection of the Yangtze River Porkeys for a long time, is also located here. Starting from a professional research perspective of the aquatic Sciences of the Chinese Academy of Sciences, long -term field patrols were carried out, and artificial intervention measures such as breeding and breeding were carried out to maintain the genetic diversity of porpoons. Its elaborate "Yangtze Relic Rescue Action Plan (2016-2025)" has become a program of action for the Yangtze River Polorner Protection.

Ten Years Ban Fishing

Followed porpoons appeared in Hubei River

In order to restore the negative impact of the Yangtze River ecology and reduce the negative impact of human economic activities, on January 1, 2020, the Ministry of Agriculture and Rural Ministry officially released the "Ten Years of Fishing Projects of the Yangtze River".

Creating a water environment that can breathe safely for porpoises is the main direction of slowing down its decline. The Yangtze River Banfish is a good news for the Yangtze River Polorner. They can not only taste a variety of fish meals, but also provide a natural survival defense line for this group of young guys to protect their lives. , Let them swim more securely.

In the first year of fishing, porpoons repeatedly appeared in the river in Hubei. In Wuhan, there have been many dolphins in the river section of the Yangtze River area; in Jingzhou, the porpoise group of the old road of the Yangtze River in Shishou Swan Island has continued to expand; in the Qianjiang section of the Hanjiang River, the first time in the past 30 years has appeared in the porpoise ...

Experts said that porpoons are the indicator species of the Yangtze River, and its frequent appearance reflects the improvement of the ecological environment brought by the ban on the arrest of the Yangtze River and the Han River. According to incomplete statistics, since 2020, the Yangtze River porpoise has appeared in the river section of Wuhan City over 20 times, nearly 100 for the first time. On July 1 of the same year, the Wuhan section of the Hanjiang River in the Yangtze River officially opened the "Ten Years of Fishing", with a total banned area of ​​330.25 square kilometers.

Protect the porpoons

Wuhan did these things

/ Start the work of "Porpherman Return to Jiangcheng"

In November 2020, Wuhan officially launched the work of "Praphs to Return to Jiangcheng", and scientific research units such as the Institute of Aquatic Biological Research of the Chinese Academy of Sciences to launch a comprehensive scientific investigation plan for water ecology such as porpoons in the Wuhan section of the Yangtze River. Scientists adopt the method of observation of water surface and underwater sound wave monitoring. In the river section of the Mountain Bridge from the Wuhan River Bridge to the Yangluo Bridge, the underwater acoustics instruments are placed every 5 kilometers. Wuhan proposed a repair plan for ecological and resource recovery.

Scientists have suggested that Wuhan should speed up the implementation of habitat restoration, fish resources recovery, and stricter shipping management measures to build Baishazhou and Tianxingzhou into the core habitat of porpoons, so that "porpoons' smiles" are stationed in Wuhan. /Establishing a technical research center for the Yangtze Rolk Breeding Preparation Technology Research Center

On May 22, 2022, the Wuhan Agricultural and Rural Bureau and the Chinese Academy of Sciences signed a co -construction cooperation agreement. Important content of work.

The Institute of Aquatic Biological Research of the Chinese Academy of Sciences, as the "national team" protected by rare aquatic animals such as the Yangtze River Freshplasm, has its national or even global leading artificial breeding and reproductive technology. Establishing the "Wuhan Yangtze Rolfne Breeding Technology Research Center" will further promote the technical advantages of the Institute of Aquatic Institute of Aquatic Academy of Sciences with the strong combination of Wuhan regional advantages. More domestic and foreign scientific research, protection and social institutions participated in the research and protection of the Yangtze River porpoise, and laid the technical foundation for artificial breeding individuals to finally return to the Yangtze River.

/5 years of census, this year announced the latest number of porpoons in the Yangtze River

According to Zhang Pianping, a researcher at the Institute of Aquatic Biological Research and Wuhan Science Popularization Regiment of the Chinese Academy of Sciences, the number of porpoons in the Yangtze River section of the Yangtze River in 2017 was about 1012. According to the arrangement of the 5 -year census, this year, the Agricultural and Rural River Basin Fisheries Administration and Management Office is about to lead and organize a large -scale Yangtze River ecological scientific examination, and then the latest number will be announced. "Let's look forward to it. Okay, the number of porpoons has risen steadily. "
