"It means the dolphin's populations are reproducing normally and heading toward effective recovery." Jiang said that they also excitedly witnessed interactions between mother and baby dolphins in Nanjing, Zhenjiang, Yangzhou and Jingjiang. "A more continuous population distribution throughout the middle and lower reaches of the Yangtze River will facilitate the migration and exchange of different dolphin groups," Liu told China Central Television on Thursday. The water areas where Yangtze finless porpoises live and move are getting larger and becoming more connected, Jiang said.Īccording to Jiang, the porpoises used to live in the cities of Nanjing and Zhenjiang in Jiangsu, but this time they observed the dolphins in several other cities along the Yangtze River, including Yangzhou, Taizhou, Wuxi, Suzhou and Nantong.Īccording to Liu Xiaoqiang, a researcher from the Ministry of Agriculture and Rural Affairs, the survey also found groups of the porpoises for the first time in the city of Wuhan in Hubei and the Chongming district in Shanghai. Six scientific research teams were sent to Central China's Hubei, East China's Anhui and Jiangsu provinces, as well as the Dongting Lake in Hunan Province and Poyang Lake in Jiangxi Province, to study the population and natural habitat of Yangtze finless porpoises from September 19 to mid-October. "Compared with the number observed in 2017, we saw more Yangtze finless porpoises in the Yangtze River in the 2022 survey, especially in terms of mother and baby dolphins, and this indicates that the natural population has partly recovered," Jiang Meng, secretary-general of the Nanjing Yangtze Finless Porpoise Conservation Association, who participated in the survey in Jiangsu, told the Global Times on Thursday. Their activity areas were also found to be larger, with many first seen in some river sections. More Yangtze finless porpoises, the critically endangered freshwater dolphin species endemic to China's longest river Yangtze, were observed during the latest scientific survey.
