No. 4448 Legend: 25 years old+porpoise Abao ushered in the "Fourth Date"

In 2007, the porpoise Abao lived in the White Cycles Pavilion (Data Map) at the aquatic Hydra. A reporter from the Yangtze River Daily reporter Gao Baoyan "At the White Cycles Pavilion of the Aquatic Institute of the Chinese Academy of Sciences, a small porpoise was recently born, number F9C22, which is the hope of the new life. Abao, it comes from the nature environment to the artificial breeding environment, and then returns to the Da. Naturally; it has been in the same hall, with 5 children, 10 grandson, and 2 great -grandson generations. It is a veritable "great -grandfather"; it is 25 years old+older, refreshing our awareness of the age of porpoons; ...

Wang Ding, the leader and researcher of the Discipline Group and Researcher of the Institute of Aquatic Biological Research Institute of the Chinese Academy of Sciences, told Abao's story on many occasions. He said: "In the field of animal protection, wild animals can return to their natural state and successfully reproduce The formation of ethnic groups is considered the best protection. "

Hubei Shishou Swan Capital Baiji Dolphin National Nature Reserve (hereinafter referred to as "Swan Island Reserve") is the world's first whale animal relocation protection area. In 1990, the five Yangtze River dolphins moved here.

In 1996, the White Rippochemical Pavilion of the Institute of Aquatic Biology of the Chinese Academy of Sciences (hereinafter referred to as the "Aquatic Institute") began to raise porpoons. At that time, there was a total of two female porpoons in the Baiyou Porch Museum.

In 2004, scientific researchers conducted a census for the porpoons in the Swan Island Reserve. Take this opportunity to pick up the strong and young male porpoons Abao, hoping that it can participate in the artificial breeding of the aquatic house and the dolphin hall. Breeding groups are prepared for the birth of small dolphins.

Abao is not afraid of people, and has a strong adaptability. Before departure, it was temporarily raised in the cage of the Swan Island Reserve for two weeks, and quickly adapted to artificially feeding bait fish.

Move to Wuhan, the self -familiar Abao has a new friend

In mid -October 2004, Abao "moved". At that time, the transportation conditions were relatively backward and rude. Scientific researchers transferred Abao to the stretcher cloth and put them into a sponge water tank. From the Swan Island Reserve to Wuhan Baiyu Dolphin Pavilion, long -distance transportation of 6 hours is very smooth.

Abao was temporarily put in a pair of ponds in the white and dolphins. It can communicate with the other three other porpoons in the main cure pool through the fence. Abao, who is familiar with, often "talks" with his partners and frequently communicates.

After half a year of breeding training, scientific researchers raised Abao and other three other dolphins. I hope Abao can find a partner and be a father earlier. Abao also quickly played with the other three dolphins.

There are little dolphins born one after another, but unfortunately Dad is not Abao

Good news soon came: mother dolphin crystal is pregnant! This is the first time that the Yangtze River Porchplay has successfully conceived in an artificial environment. Everyone guess, maybe Abao is a father.

On July 5, 2005, the little dolphin was born. This is the first Yangtzepin porchian in the world's artificial breeding environment to successfully breed through natural mating. The parent -child appraisal results show that Taotao's father is another male dolphin Afu.

By 2010, there were three small porpoons in the Bai and Dolphin Pavilion, but these small porpoons had no blood relationship with Abao.

Soft release technology research, let Abao return to his hometown

At this time, scientific researchers carried out a soft release technology research. The main purpose was to test the porpoons living in an artificial breeding environment, and whether they could adapt to the living environment of nature again. After comprehensive consideration, I decided to put Abao back to the hometown of Swan Island.

In the early days of soft release, Abao first needed to domesticate in floating cages, because for artificially raised high animals, returning to the natural environment again was a severe survival test. Scientific researchers are worried that Abao has lived in the artificial environment for nearly 7 years. Can it still fish by itself? Can you combine with other wild dolphins?

In 2011, before the porch "Abao" was put back in nature, the researcher Wang Ding (third right in the front row) of the Institute of Aquatic Institute of Chinese Academy of Sciences did the last physical examination (data chart).

Starting in March 2011, scientific researchers have carefully designed Abao's wildization process: first feed Abao in the white and dolphins, about one month, Abao can already capture live fish himself by himself ; In April, the adaptive domestication of Abao was transported to the cage of the Swan Island Reserve, and Abao adapted to only 2 weeks; then, Abao was put in a large fence. This is a closed natural environment. Small fish can be able to Drilling into the fence in and out of freely, Abao preyssing smoothly.

Researchers did the last medical examination for Abao. After confirming that its weight and other indicators were completely normal, they installed permanent miniature chips for Abao. The number of chip numbers was 4448. This is its ID card.

On June 1, 2011, the fence opened, and Abao returned to the natural waters of the Swan Island Reserve. Abao quickly swims out of the fence, not far away, and turns around to enter the fence and go around, looking around reluctantly. In the end, after several outlets, Abao disappeared into the water. ▌Five

After 4448, the reunion of the reunion was 4448.

Can Abao adapt to the survival environment in the wild? Is Abao okay? Researchers always care about Abao.

In November 2015, scientific researchers conducted a comprehensive group census on the porpoise in the hometown of the Swan Island Reserve.

On November 20, the eighth head of the porpoise was water. It was relatively large. The tail was outside the stretcher cloth. A familiar scar on the tail immediately attracted the attention of scientific researchers: this is the symbol of Abao!

4448! It was confirmed by the scanning instrument that the number of chip numbers was 4448. "Abao, this is our Abao!" Researchers shouted excitedly.

During the porpoise census in 2015, Wang Ding (first right in front row) of the Institute of Aquatic Institute of Chinese Academy of Sciences (first row) and Abao reunited with Abao (data map).

Everyone is very excited, as if looking back at children who have been disappeared for many years. For more than 4 years, Abao's weight has almost changed, 46.8 kilograms, still fat and embarrassing. During the entire medical examination, Abao did not struggle, and cooperated very well, as if recognizing his old friends, remembering the artificial breeding life of the White Poly Porch Museum for nearly 7 years.

After the census, scientific researchers built a close relationship with the porpoons of the Swan Island Reserve through molecular biotechnology. As a result, it was even more surprising that Abao was in Swan Island and was already the same hall in the fourth generation!

Before leaving the old way of Swan Island in 2004, Abao breed at least two sub -generations. After returning to his hometown in 2011, he breeded at least 3 sub -generations. In particular, it is very happy that the children who breed before 2004 gave Abao at least 10 grandson (female) and 2 great -grandson.

Abao is full of children and grandchildren, and is the "great -grandfather" of the fourth generation.

Last year, I saw Abao again, it was 25 years old

"The magical special, the legendary life." Dr. Hao Yujiang, an associate researcher at the Institute of Aquatic Institute of Aquatic Academy of Sciences, summarized Abao's experience in this sentence.

Hao Yujiang said that Abao's tail was injured, so there was a scar, which also became a very important appearance feature of Abao. During the 2015 Grand Census, Abao had already had the same hall and had a large family. At that time, it was 17 or eight years old, and it was a middle -aged and elderly individual.

In 2021, scientific researchers conducted another physical examination of the porpoons of Swan Island, and Abao was caught again. According to calculations, Abao's age should be over 25 years old. "Generally, we believe that the age of porpoons is about 20 years old. Abao once again refreshed our awareness of the age of porpoons. know."

Abao is the only porpoch who has experienced the artificial breeding and relocation of the Yangtze River in the Yangtze River. Now it may also live in the Swan Island Reserve healthy. In the future, scientific researchers plan to re -introduce the peclust in the relocation protection area to the Yangtze River.

Abao's story tells us that the long -term breeding of the Yangtze River porpoons in the artificial environment can still re -adapt to the natural environment through scientific adaptation and domestication, and can successfully reproduce. The porpoise's breeding plan provides strong technical support. The protection experience of the Yangtze River in China has also won the high affirmation and active promotion of international organizations.

Abao's legendary life has become a model of scientific protection of porpoons. Wang Ding, the leader and researcher of the Discipline Group and Researcher of the Institute of Aquatic Biological Research Institute of the Chinese Academy of Sciences, told Abao's story on many occasions. He said: "In the field of animal protection, wild animals can return to their natural state and successfully reproduce The formation of ethnic groups is regarded as the best protection. "Although it is still important, the research and protection of the Yangtzepuki in China has ushered in" dawn hope "for more than 40 years.

At the first International Fresh and Dolphin Protection Biology Conference held in Wuhan in 1986, Chinese scientists proposed the three major protection measures that combined local protection, relocation protection, artificial breeding and reproduction research.

In 2016, the "Yangtzepin Porch Rescue Action Plan" came out. In 2021, the "National Key Protection Wildlife List", which has been renamed for the first time in 2021, officially upgraded the Yangtze River Polustion into a national first -class protection animal. Since 2021, the Yangtze River has officially opened the "Ten Years Ban Fishing". The Wuhan Municipal Government has also introduced the "Top Ten Measures" to promote the return of the Yangtze River in the river section of the Yangtze River. Protection and repair.

Since 2017, the trend of accelerated decline in the population population of the Yangtze River has been curbed. The number of porpoons in the Yangtze River is currently stabilized at about 1,000 heads. 10 dolphins have been built in the middle and lower reaches of the Yangtze River. One -third of the river section is also the most important water area for the recovery of the peels of the Yangtze River in the future.
