"F9C22", hello, warmly welcome!

Xinhua News Agency, Wuhan, July 6 (Reporter Wang Ziyi, Tan Yuanbin) Sometimes diving, sometimes exposing the water, sometimes traveling in the water ... In the Baiyou Dolphin Pavilion of the Institute of Aquatic Biological Research of the Chinese Academy of Sciences, the Yangtze dolphin "F9C22" is in the mother Playing with "Fushou", the mother and daughter are like a shadow and their fun.

On the 6th, the Chinese Academy of Sciences Passing through Xinhua News Agency for the first time released the "hero mother" - "Fujiu" gave birth to a new baby's entire process monitoring video. The birth of this little porpoise was a new result of artificially raising the Yangtze River in the Yangtze River.

The Yangtze River porpoise is a national first -class protection of wildlife. The results of the 2017 Yangtze Relief Ecological Science Expedition showed that the number of porpoons in the Yangtze River is only about 1012 heads. 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 also 6 Yangtzepin porpoises, three of which are the Yangtze River porpoons born in the artificial environment, including the first second -generation Yangtian Polor "YYC" born in 2020. This In order to understand the basic biology and reproductive physiology of the Yangtze River, it has provided important conditions.

It is reported that May to August of each year is the peak period of the Baiyou Porch Pavilion Yangtzepin Breeding. In August last year, scientific researchers of the Institute of Aquatic Academy of Sciences conducted a physical examination of the female Yangtzepin Porchrald through B -ultrasound to confirm that it had been pregnant for more than a month The pregnancy period of the Yangtze River is about 12 months, so it is estimated that its due date may be around mid -to -late June this year.

Hao Yujiang, an associate researcher at the Institute of Aquatic Institute of Chinese Academy of Sciences, said 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 pregnancy in pregnancy, scientific researchers have added freshness to "Fujiu". The bait fish and supplement vitamins, mineral elements and other nutrients.

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 that 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 that night, and the number was "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 relationship between mother and daughter 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" of this "F9C22" was a female porpoise. Essence

"The theoretical knowledge and basic technologies accumulated through the artificial accumulation of porpoons are essential for supporting the land and relocation of the porpoons of the Yangtze River." Wang Kexiong, the head of the Whale Discipline Group of the Aquatic Institute of Aquatic Institute of Aquatic Institute of Chinese Academy of Sciences, said that the institute has always insisted on the white puffer dolphin and The research and protection of 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.
