With the advent of summer, the Yangtze River Poyang Lake Aquatic Biological Protection Base "Neophocaena Bay" in Hukou County, Jiangxi Province is becoming more and more bustling. An endless stream of tourists and teams of students who come to study form a long queue at the entrance of the visit. Hukou County is located at the junction of the Yangtze River and Poyang Lake, and the "porpoise bay" is being built near the water. "Only half a year after its opening, the museum has received more than 100000 tourists. This popularity is inseparable from the charm of the finless porpoise," said Lu Weijun, member of the Standing Committee of Hukou County Party Committee and head of the Publicity Department. It turned out that in February this year, two Yangtze finless porpoises were found trapped in the Songmen Mountains of Poyang Lake. In order to rescue the two "water treasures", Hukou County turned a branch of Poyang Lake into a temporary breeding base for the two Yangtze finless porpoises to paddle in the water. Yu Xianhua, director of Hukou County Yangtze River Poyang Lake Aquatic Life Protection and Rescue Center, said that this is the first time Jiangxi has carried out ex situ protection of Yangtze River finless porpoises. "A special person will patrol every day, and 3000 jin of fish fry will be put in every month to feed them." The scientific survey data of Yangtze finless porpoise in the whole basin of the Ministry of Agriculture and Rural Affairs in 2022 shows that the population of Yangtze finless porpoise is 1249, including about 595 in the main stream of the Yangtze River, about 492 in Poyang Lake. The river section of Hubei, Jiangxi, Anhui and other provinces is an important habitat for Yangtze finless porpoise. According to Wang Ding, an expert in the study of Yangtze River finless porpoises and a researcher at the Institute of Aquatics of the Chinese Academy of Sciences, there are currently three types of protection measures for Yangtze River finless porpoises: on-site protection, ex situ protection, and artificial breeding. Among them, the key point of on-site protection is to take measures to create a good Lebensraum for the wild reproduction of Yangtze finless porpoise; Artificial breeding mainly provides theoretical and technical support for the protection of finless porpoises through scientific research; Ex-situ protection refers to the artificial migration of the Yangtze River finless porpoise to areas more suitable for its growth, helping it achieve population expansion. At present, significant progress has been made in various protection measures for the Yangtze River finless porpoise. ——China's ex situ conservation of the Yangtze River finless porpoise has been released to the Yangtze River for the first time. The ultimate goal of ex situ conservation for the Yangtze River finless porpoise is to return it to its original habitat and achieve natural reproduction and reproduction. On April 25th of this year, four ex situ protected Yangtze River finless porpoises from the former route of Tian'ezhou on the Yangtze River were released into the Xinluo and Shishou sections of the main stream of the Yangtze River in batches, successfully completing the final key technical loop of the Yangtze River finless porpoise protection technology system. ——The number of finless porpoises in ex situ protected areas is rapidly increasing. Entering the Anqing Xijiang Yangtze River Porpoise Relocation Protection Center in Anhui, 21 relocated Yangtze River Porpoise were playing along the clear and clear Xijiang Yangtze River Old Road. Deputy director of the center, Yu Yousheng, took out his phone and took several consecutive photos of the water surface, capturing the joyful scene of several Yangtze River Porpoise chasing in the water. At present, there are over a hundred Yangtze finless porpoises that have been bred, exported, and relocated to protected areas along the old Yangtze River routes, including Anqing Xijiang and Hubei Tian'ezhou. ——Scientific breakthroughs have been made in the full artificial breeding of the Yangtze River finless porpoise. Arriving at the Baiji Porpoise Hall of the Institute of Aquatics of the Chinese Academy of Sciences, the little finless porpoise "Xiaojiujiu", codenamed "F9C22", celebrated its first birthday. On June 27th last year, "Xiaojiujiu" was born under the close monitoring of scientific researchers, and billions of netizens collectively watched its birth through online live streaming. At present, the number of artificially raised Yangtze River finless porpoises in the Baiji Porpoise Museum has reached 11. Among them, four are Yangtze River finless porpoises born in artificial breeding environments. The in-situ protection of the natural population of the Yangtze River finless porpoise is closely related to the natural ecological environment of its habitat
