Yangtzepin "Hero Mother" and "Timing"

Sometimes diving bottom, sometimes out of the water, and sometimes swimming in the water ... At the Baiyu Polch Pavilion of the Institute of Aquatic Biology of the Chinese Academy of Sciences, the "F9C22" of the Yangtze Rolling Dolphin "F9C22" is being played with her mother's "Fujiu", such as the shadow and its 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 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 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 from May to August each year is the peak period of the Baiji Puffer Museum Yangtzepin. In August last year, the scientific researchers of the Institute of Aquatic Academy of Sciences conducted a physical examination of the female Yangtzepin Porchrald through B -ultrasound and confirmed that they had been pregnant for more than a month. The pregnancy period of the Yangtze River is about 12 months. Therefore, 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 "blessing" has increased steadily, and the maximum daily eating amount can reach 3 to 4 kg. In order to meet the nutritional needs of the pregnancy of 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". 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.

"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, head of the Whale Discipline Group of the Aquatic Institute of Aquatic Institute of Aquatic Institute of Sciences, said that in the forty years since the establishment, The research and protection of the Baiyou dolphin and the Yangtze River porpoise has been 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.
