Over the years, porpoons have been in Wuhan

Many interesting stories have always happened

Now this "smile angel" little cute

Still writing wonderful in Wuhan

Wuhan released

"Smile Angel in Wuhan" column second phase

Tell you the story of porpoons and Wuhan for you

Number "F9C22"

Welcome, baby dolphin baby

Number "F9C22"! This is the number of newly born porpoons! With a burst of blood water, the umbilical cord connected between the porpoise and the mother of the porpoise and the mother of the porpoise was disconnected. The porpoise was like a shell, and it quickly ejected the water surface. After breathing the first air, it quickly returned to her mother. They were accompanied by each other, sometimes diving, sometimes exposing the water, sometimes swimming in the water ... The "F9C22" of the peculiar dolphin "F9C22" of the Yangtze River is playing with her mother's "Fujiu". They are like a shadow and they are happy.

On July 6, the Institute of Aquatic Institute of Chinese Academy of Sciences passed the Xinhua News Agency for the first time "Hero Mother" - "Fujiu" gave birth to a new baby's entire process monitoring video. The birth of this small porpoise was a new result of artificial breeding of the Yangtze River dolphin.

On the left side of the monitoring screen, at the moment of childbirth, a bloodwater sprayed, and the small dolphin ejected the water surface like an artillery shell, and quickly swam back to the water.

The Yangtze River porpoise is a national first -class protection of wildlife. The results of the 2017 Yangtze Relief Ecological Science Investigation showed that the number of porpoons in the Yangtze River is only about 1012 heads, which is rare than giant pandas. Over the years, many Yangtzechin research and protection institutions in the United Nations of the Chinese Academy of Sciences have continued to explore the artificial cultivation of the Yangtze River Porpoons.

At present, in addition to the newly born "F9C22", there are 6 Yangtzepin porpoises in the White Cycles Pavilion of the Chinese Academy of Sciences, three of which are the Yangtze River porpoons born in the artificial environment, including the first second second. On behalf of the Yangtzepin "YYC", this provides an important platform for understanding the basic biology and breeding physiology of the Yangtze River.

Hao Yujiang, an associate researcher at the Institute of Aquatic Institute of Aquatic Institute of Chinese Academy of Sciences, introduced that since pregnancy, the amount of "Fujiu" has grown steadily, and the maximum daily eating amount can reach 3-4 kg. In order to meet the nutritional needs of the pregnancy of pregnancy, scientific researchers have increased their fresh ones to "Fujiu". Bait fish, and supplement nutrients such as vitamins and mineral elements.

At 16:00 on June 27, "Fujiu" appeared obvious appetite decline, shorter breathing interval, and floating. At the same time, the trainer found that the color liquid overflowing in the reproductive cracking area was overflowed. Corresponding plan. At 19:35 on the same day, the tail fins of the young dolphin were delivered. After about 2 hours of delivery, the young dolphin was successfully delivered at about 21:35 on the same day and was numbered "F9C22".

Hao Yujiang said that after the "F9C22" was born, "Fujiu" showed a strong maternal nature, and has been actively following the care, guiding the "F9C22" diving and accompanied by it. Under the guidance of "Fujiu", the parent -child relationship was gradually established. "F9C22" ate the first bite of breast milk around 4:30 the next day. After more than a week of observation, her mother "Fujiu" and her newborn baby "F9C22" are currently healthy.

It is reported that "Fujiu" was moved into the White Cycles Pavilion of the Chinese Academy of Sciences from Poyang Lake in 2011. It is currently 14 years old and is in the age of age. On the third day after the birth of the porpoch, after observation and confirmation of scientific researchers, the "F9C22" born of "Fujiu" was a female porpoise. Essence

"The theoretical knowledge and basic technologies accumulated through the artificial accumulation of porpoons are essential for supporting the ground and relocation of the porpoons of the Yangtze River." Researcher Wang Kexiong, the person in charge of the Whale Discipline Group of the Aquatic Institute of Aquatic Institute of Aquatic Institute of Sciences Adhering to the research and protection of the Baiyou dolphin and the Yangtze River porpoise is currently the research team with the longest time to engage in whale protection biology research, the most complete discipline category, and the most active international cooperation in China.

Natural delivery for more than ten hours

Mother porpoise is very hard

Dr. Hao Yujiang introduced that "Fujiu" came from Poyang Lake to the aquatic office in 2011, and was 14 years old. This time it was not a first -tired. Before that, it had experience in childbirth. When the first child was born, there was a small number of porpoons. He was a little scared and often avoided the small dolphin. Due to his insufficient experience, he could not successfully breastfeed. First, the first. It is a pity that the fetus has not succeeded.

During childbirth, clearly visible small tails.

From May to August each year is the peak period of the Baiyou Dolphin Museum Yangtzepin. In August last year, scientific researchers in the Institute of Aquatic Academy of Sciences conducted a physical examination of the female Yangtze Rolls in the B -ultrasound and confirmed that they had been pregnant for more than a month. The pregnancy period is about 12 months, so it is estimated that its due date may be around mid -to -late June this year.

During the peculiar breeding period of last year to July, according to the male and female combination, the researchers put the two male porpoons in a pool with "Fujiu" at the same time, looking forward to the spark of love.

One is "Taotao", which was born in the Wuhan Baiyou Dolphin Pavilion on July 5, 2005. It is the first porpoise born in the world in the artificial environment. The other end is "E wave". Born in 2018, he just entered the sexual maturity period. But who is Dad? After the "F9C22" state is stable, it can be determined after DNA detection. The tail of the porpoise comes out first, which is clearly visible.

There will be some typical behavioral characteristics before childbirth. One is that the appetite decreases, and it rarely eats from 12 hours to 24 hours. C -shaped is a manifestation of contractions.

"Fujiu" before liked to swim against the time of clockwise, it became a clockwise swimming before giving birth. It may also adjust the body because of pain. It will rotate the body while swimming to adjust the position of the fetus.

Fujiu has been swimming in the clock in the pool.

There are three stages of natural childbirth. The first stage is that the uterus is frequently contracted, and the parent dolphin will swim and jump quickly when it is painful. The second stage is the fetal membrane out of the mother's body. The tail of the young dolphin comes out first. When the navel is born, the pawn will suddenly accelerate, throw the entire body of the young dolphin like a shell, and then the umbilical cord will break. Breathing out of water for a while, the entire outbound process is about 1 hour to 2.5 hours. After the young dolphin is born, it will take another 7.5 hours to 8 hours to fall off the entire placenta. The entire labor process was about ten hours, and the mother dolphin was very hard.

After the porpoise is born

Three firsts of "Dolphin"

The porpoons born in the water must complete the first step of the three major "prescribed actions" of the three major "prescribed actions" of the three major "prescribed actions" in the first time in the first time, the first breathing air, and the first sucking breast milk.

Break free from umbilical cord

According to the conventional, after the young dolphin is naturally delivered, the umbilical cord will be disconnected automatically with the pull of the umbilical cord.

Breathe the first air

After the umbilical cord is disconnected, the young dolphin will quickly rush to the water, breathing the first air after leaving the mother.

Almost at the same time, the mother dolphin will quickly travel with the young dolphin, or hold the young dolphin together, and the mother and son began to communicate for the first time.

Sucking the first breast milk

Within a day of birth, if you ca n’t eat breast milk, you will be in danger of life. However, the first bite of milk needs to be completed by collaborating with the mother and son of the porpoise.

The nipples of the mother dolphin are hidden in an injecting structure. The professional name is "cream", which is located at both ends of the abdominal reproductive cracks.

Wang Ding, a researcher at the Institute of Aquatic Institute of Chinese Academy of Sciences, introduced that when porpoons breastfeeding, young dolphins need to close the abdomen of the mother dolphin, and the mother dolphin slightly sides to the side, exposing the fins on one side, and bulging in the abdomen to wipe the young dolphins. In order to attract young dolphins and close the nipples close to the mouth of young dolphins.

When the young dolphin finds the mother's nipple position, the tongue will be rolled up in the upper jaw to form a tubular space, and then the beak is drilled forward into the mother's cream, and the "tube" is put on the mother's nipples. Different from terrestrial animals, the pawn contracted through the muscle around the cervix and spray milk into the young dolphin's mouth.

At the beginning, the pair of dolphins also shot the emulsion outside the young dolphin, and a ray of white mist appeared in the water. This shows that the young dolphin's first sucking skills are very sparse, and the inhaled breast milk is not sufficient. At this stage, the number of young dolphins will be very frequent. If the young dolphin gradually reduces the number of sucking times, it means that the young dolphin has mastered the suction skills.

The mother -child and child of the porpoise peer on the side of the water, and the mother dolphin will alternate breastfeeding with both sides of the nipples. These underwater breastfeeding processes are completely carried out during swimming, which is very similar to the aircraft air.

How long is the age and life of porpoons?

At the age of 4-9, it has matured and has a life span of about 20 years. But a porpoise named Abao is already over 25 years old, so there is also a difference in the life of the porpoons.

Will porpoons have twins?

Won't. The fertility rate of whale dolphins is lower than other smaller animals. Each child has only one porpoise "baby". It is generally 70 cm in length and weighs 5 kg, and it must be pregnant for 12 months.

Does the porpoise know that he has a child?

In the porpoise group, the porpoise father generally does not know that he is a father. Porpherd is a typical seasonal breeding animal. It will breed from April to October and is concentrated in July to September. During the breeding season, male porpoons have certain aggressiveness for female porpoons, but porpoons are very mild animals, and aggressive behaviors can basically be ignored. However, in order to ensure safety during pregnancy, scientific researchers will arrange their mother to give birth in a pool alone.

The porpoise's eyes are so small, isn't the eyes not good?

Porpherd's vision is not good, but the hearing is great. When the dolphin emits sound waves, when the sound waves meet the surrounding objects to reflect back, they can judge the location of the surrounding objects. This special ability is called echo positioning.

Dolphin does not sleep?

Different from other animals in the porpoch's sleeping, they rest alternately on the left and right brains. When the left brain controls swimming, the right brain rests, and the right brain controls the swimming, the left brain rests.

How do scientific researchers interact with porpoons?

There are often scientific research in the Polor Pavilion. The trainer is responsible for the daily life of the porpoise. Based on the porpoise's interaction with them, at the same time assist medical examinations, conduct non -infringement of physical examination, collect samples such as blood, feces, urine, etc. , Physical condition, etc. At the same time, it can help scientific researchers to study the living habits of porpoons, and how to mate, reproduce, childbirth, etc., so as to better study the current situation of porpoons' field protection.

The ecological environment of the Yangtze River Economic Belt improves

Protect the ecological environment of the Yangtze River Economic Belt and protect the Yangtze Rolls, which has attracted more and more attention.

At a press conference held today, Zhai Qing, deputy minister of the Ministry of Ecology and Environment, introduced: Central Ecological Environmental Protection Inspector has taken the ecological environment warning film for the Yangtze River Economic Belt for 5 consecutive years, and rectification of the problems listed in the alarm film. Promote the solution of outstanding problems in various places, promote the adjustment of the industrial structure throughout the 11 provinces (cities) of the Yangtze River Economic Belt, accelerate the improvement of the coastline and pollution prevention. In 2020, the dry flow of the Yangtze River achieved the first time the entire line reached the Ⅱ water quality. This is not easy. Biological diversity has been significantly enhanced, the "Smile Angel" porpoons appear in groups, and the ecological environmental protection of the Yangtze River Economic Belt has changed.

Zhai Qing, deputy minister of the Ministry of Ecology and Environment, introduced at a press conference that the "Smile Angel" porpoons appeared in groups, indicating that the ecological environment of the Yangtze River Economic Belt is improving.

Zhai Qing emphasized that the central ecological environmental protection inspector paid close attention to the implementation of ecological environmental protection requirements in the implementation of the major strategic implementation of the region, and focused on conducting inspectors around different positioning and characteristics. For example, when inspecting relevant provinces in the Yangtze River Economic Belt, we closely focus on the requirements of "grasping the big protection and not engaged in big development", focusing on the "ten years of fishing for fishing", shoreline protection, water ecological protection and repair, and pollution prevention. The Yangtze River warning films have pointed out 623 outstanding issues, including bad fishing, shore destruction, illegal occupation of nature reserve, etc. These issues have been rectified as of now.

"Family Portrait"

This is a big family

The National Aquatic Wildlife Protection Branch, the Yangtze River Daily Newspaper Group, and the Wuhan Education and Science Research Institute are jointly drawing the "Yangtzepin Qiplin" hand -picture book. In addition to the porpoons selected yesterday, the porch delivery, breathing and other chapters, as well as the "family portrait" series of porpoons. This is also a big family!
