    eve of the Chinese New Year, a message pleased and cheered Xu Xudong, a researcher at the
    National Committee of the Chinese People's Political Consultative Conference
    and the China
    Institute of Aquatic Biology.
    February 5, the State Forestry and Prairie Administration and the Ministry of Agriculture and Rural Affairs jointly issued a public announcement, officially announcing the revised National List of Key Wildlife Conservation (hereinafter referred to as the Directory). This is the first large-scale adjustment of the Directory since its release in 1989. In the adjusted Directory, 65 kinds of animals, such as slugs and Yangtze River porpoises, have been upgraded from the second-level protection of wild animals to the protection of wild animals at the national level.
    "upgrade" of the Yangtze River porpoise, there are Xu Xudong and others for many years to call for the figure. As early as 2015 on the national
    , Xu Xudong in the submission of the General Assembly's written statement "the Yangtze River owns its own golden road, the Yangtze River has its own fish and dolphin township" pointed out that the Yangtze River basin is facing a serious water ecological crisis, white finfish, white slugs, mackerel has not been seen for many years, porpoise only about a thousand head, about a <2>% of the Yangtze River species into the endangered list.
    Yangtze River porpoise, commonly known as river pigs. It has existed on Earth for 25 million years and is the only freshwater porpoise left in the Yangtze River basin. Since the 1990s, the population of the Yangtze River porpoise has declined rapidly. "In 1991, the number of porpoises in the Yangtze River was more than 2,700. In 2006, a joint international survey found that there were less than 1,800 porpoises in the Yangtze River. The results of the 2017 ecological scientific survey of the Yangtze River porpoise show that the population of the Yangtze River porpoise is about 1012, of which 445 are in the Yangtze River main stream, 110 are in Dongting Lake and 457 are in Poyang Lake. Xu Xudong cites a set of data that confirms the growing endangered yangtze river porpoise.
    Porpoise is a mammal at the top of the food chain of the Yangtze River ecosystem and is very sensitive to environmental changes. Its number is a mirror of the health of the Yangtze River ecosystem. In Xu Xudong's view, the yangtze River porpoise population is critically endangered is the result of a variety of human activities, such as river and lake barriers and cold fishing led to a sharp decline in fish stocks, porpoise food shortage, rapid development of the shipping industry interfere with the sonar communication of porpoise, water pollution reduces porpoise reproduction, fishing gear and boats mistakenly injured porpoise.
    protect the porpoise, in a sense, but also to protect the Yangtze River. During the 2017 national
    , Xu Xudong jointly submitted a joint proposal to the National Committee of the Chinese People's Political Consultative Conference
    , proposing to raise the protection level of the Yangtze River porpoise from the second level to the first level. At the 2018 National
    , Xu Xudong once again suggested that the key protection of animals and plants from the institutional mechanism to solve the problem of revising the "old difficulties", as soon as possible the Yangtze River porpoise into the national level to protect wildlife list. "According to China's Wildlife Protection Law, the level of protection of wild animals is different, in terms of protection and management are different. It is of great significance to raise the protection level of yangtze river porpoise, strengthen its protection and curb the rapid decline of porpoise population. Xu Xudong pointed out.
    January 2021, a 10-year fishing ban was introduced in key waters of the Yangtze River basin. In March 2021, the Yangtze River Protection Law will come into force. A flurry of good news has left Xu Xudong optimistic about the prospects for the protection of the Yangtze River porpoise. He said that the CPPCC Central Committee has also included the implementation and effectiveness of the 10-year fishing ban on the Yangtze River in the future long-term follow-up research topics.
    " at present, the Yangtze River protection has become the main tone, but from a national perspective, some government departments still pay more attention to water quality, not enough attention to water life. Aquatic biodiversity is an important aspect of the integrity of water ecosystems. "Based on years of sustained concern for aquatic life, xudong's current proposal still focuses on aquatic conservation and water environmental protection.
    Xu Xudong stressed that biodiversity is one of the necessary foundations of benign ecosystems, and the realization of water ecosystem functions also needs to be supported by biodiversity, such as the self-purification of water bodies, fishery output of rivers and lakes, etc., which depend on biodiversity and biological dependence. Protecting biodiversity and protecting the survival and reproduction of different species is also part of human civilization. "If there is only water, there are no living things, how can we call it 'water ecology'?" Xu Xudong has been on the road for the protection of aquatic organisms with drums and huh.
