Guyun New Voice of the Yangtze River | Famous Zoologist Zhou Kaiya's "wish"

When referring to Zhou Kaiya, a senior zoologist and a senior professor at Nanjing Normal University, he could not turn around the rare mammal "white and dolphin" in the Yangtze River. Correcting the knowledge of the industry's white and the scope of the distribution of dolphins, and establishing the Bai and Dolphin family, which is the "rectification of the name" for the white and dolphins ... It can be said that his life is running for the research and protection of white and dolphins.

In Zhou Kaia's memories, he was able to associate with Bai and Dolphin at first, from a "strange fish" displayed in the specimen room displayed in Nanjing Normal University (later "Nanjing Normal University"). This "strange fish" was arrested by Nanjing fishermen in 1956, and was immediately sent to Nanjing Normal University to make specimens. It is not only huge in size, and the proportion of bones is rare. There is still a long beak at the front end. At that time, no one could call the name of this "strange fish". As a result, Zhou Kaiya checked a large number of literatures for research and visited the fishermen in Nanjing to determine that his identity was white and dolphin. "Before that, no one had reported the news that there were white and dolphins in the Nanjing section of the Yangtze River. At that time, the industry generally believed that white and dolphins only lived in the waters of the Yangtze River in Dongting Lake and nearby." He ran a number of museums to find clues, and finally saw the specimen of white and dolphins in the Shanghai museum. "These evidences can prove that there is also white and dolphin in the lower reaches of the Yangtze River." So in 1958, Zhou Kaiya published "White and Dolphin Found in the lower reaches of the Yangtze River" in the "Science Bronze" to correct the inherent views of the international academic circles and the distribution of dolphins. The middle reaches "eastward to the" lower reaches of the Yangtze River near Nanjing -Shanghai ".

In 1974, the Editorial Editorial Committee of the Chinese Academy of Sciences invited Zhou Kaiya to be responsible for the writing tasks of multiple species entries including "White and Dolphin", and provided a research funding. Jiangsu, Anhui, Jiangxi, Hunan, and Hubei retrieved the clues of white and dolphins. "Every time I go, I ran to the local fishery communes, fishery brigades and fishery bureaus to inquire about the situation, and ran for more than 3 months." Zhou Kaiya said that the local fishermen when I walked to Yichang confirmed that the local old fishermen confirmed to be in the nearby Huangling Temple. I have seen white and dolphins near the waters. It can be seen that the distribution of white and dolphins is much larger than the original knowledge. , Even Bai and Dolphin have been in the area of ​​Fuchunjiang, Zhejiang Province. "

With the continuous deepening of research, Zhou Kaiya gradually explored the tentacles of scientific research to the name and classification field of white and dolphins. "The earliest white and dolphins in the record were discovered by an American with a gun in Dongting Lake. Local fishermen called this fish 'white and" white flag "because of their words. Its name is White Flag Dolphin, that is, 'white flag dolphin'. "Zhou Kaiya introduced that although Chinese scholars changed the" white flag "to" white fin "during the translation process, its fins were not white, so such naming also had deviations. Essence At the same time, the international academic community has always believed that the types of white and dolphins salvaged in Dongting Lake, China were the same as the "Asian Puffer Department" in the Amazon River in South America, and also questioned this week Kaia.经过不懈努力，在中文系教授的帮助下，周开亚在古籍《尔雅》里找到了相关表述：“鱀，䱜属也，体似鲟，尾如鱼。喙小，锐而长，齿罗生, The upper and lower titles, the nose is on the forehead, can make sounds, less meat, more paste, viviparous, fine fish, big and long -sized bunny. "Then, through systematic research, it has proved that white and white and white and white and whiteness Dolphin bones, stomach and other structures are different from Asian puffer fish. In 1978, Zhou Kaiya wrote for the first time that white and dolphins were the existing representatives of another type of ancient tooth whale, and they should be divided into "white and dolphins" separately. Through years of hard work, it is finally "rectified" for the rare mammals in the Yangtze River Water of the Yangtze River in China.

The Bai and Dolphin Protection Blood written by Zhou Kaia that year

The torrent of the times has rolled forward. With the development of the economy, after the 1980s, the ecological environment along the Yangtze River continued to deteriorate, bringing a huge survival crisis to white and dolphins. In 1982, Zhou Kaiya published the "Protection of White and Dolphin", pointing out that the number of white and dolphins was only 400, and proposed to relocate the protection plan, hoping to raise white and dolphin circles to establish artificial breeding technology. "During the inspection along the river, we saw the sewage outlets that passed through the river, and the white and dolphin trapped by illegal use of fishing gear, and we were anxious." Zhou Kaiya said that with the help of public welfare organizations such as the World Nature Foundation (WWF) He and his colleagues wrote printed and printed propaganda paintings and popular science books about white and dolphins, and distributed them to fishermen and primary and secondary schools along the river. However, these efforts cannot change the current situation of the number of white and dolphin population year by year. "The front end is a long beak, with a triangle -like dorsal fin. White and dolphin as aquatic mammals need to breathe with the lungs, and regularly surface to air on the surface. Therefore, if there is a surviving white and dolphin in the Yangtze River, then it It is easy to be seen when jumping out of the water. "Zhou Kaiya clearly remembered that as early as 1989, he also witnessed the scene where porpoons, white and dolphins swim on the river at the same time, and captured this precious picture with a camera. Become the most precious memory in my life. " With the death of the last white and dolphins in 2002, it is difficult for the world to find the trace of white and dolphins.

Time, to this day, Zhou Kaiya is nearly ninety. In his eyes, in recent years, the ecological environment of the river has undergone tremendous changes. "In 2020, I took the boat to the river again, and I couldn't see the sewage outlets and fishing fishing boats along the Yangtze River. I am particularly happy that our country proposed the policy of the Yangtze River" ten years for fishing '. It is really important to restore the rare aquatic animals such as the Yangtze River fish resources and protect the porpoons. "At the same time, the whole society has a great leap in ecological protection. Environmental work. The "Frequently Aquatic Wildlife Identification Manual of Nanjing", which knows the binding binding binding binding and booked a beautifully published in the near future, said happily: "Compared with the protection of the past, it is one in the sky and one in the ground." Seeing the Yangtze River seeing the Yangtze River. The protection of porpoises is good year by year. Zhou Kaiya said that now his biggest wish is "I hope porpoons can accompany the people in Nanjing for a long time."

Ancient and modern blending, showing a different "beauty of the Yangtze River". The "Ancient Rhyme New Voice of the Yangtze River" column is one of the series of activities of the "Yangtze River Protection · Green Growth Growth" action plan. It is launched every week.

The "Yangtze River Protection · Green Growth" action plan was co -sponsored by the Jiangsu Provincial Department of Ecological and Environment, the Propaganda Department of the Provincial Party Committee, the Provincial Civilization Office, the Provincial Education Department, the Communist Youth League Jiangsu Provincial Party Committee, the Provincial Women's Federation, and Xinhua Newspaper Media Group. The environmental protection publicity and education center, the Provincial Institute of Environmental Sciences, and the Jiao Dian News jointly launched on June 5, 2019. This theme activity is from the perspective of children's growth. The "Yangtze River Protection Small Meaning" will continue to record documentary records for 12 years, which will reflect the improvement of the quality of the ecological environment of the Yangtze River.
