 The Changjiang goddess of the white dolphin, which has disappeared for many years, has been photographed? Experts give advice


The baiji, known as field functional extinction, has been photographed. 21 p. m. on May 2nd The Chinese green hair Club micro-blog sends out this message Immediately arouse the attention of the people in the circle Some people cheered and some were doubtful. If it was a white dolphin, it meant a great deal! White Dolphin A member of a small individual in the cetacean family Freshwater cetaceans endemic to the Yangtze River in China Constant temperature animals, pulmonary breathing Known as the giant panda in the water The last captive Baiji dolphin Qi Qi reporter Gao Baoyan Zhang Xianfeng source: Changjiang Daily image natural studio As early as in ancient times, there were records about the white dolphin. In the ancient book Er Ya, the white dolphin was described as the goddess of the Yangtze River. Due to the excessive development and pollution of the Yangtze River, the number of them has declined rapidly in the last century. Because of the rare number, the white dolphin is not only classified as a national first class protected animal, but also one of the 12 most endangered species in the world. In 2006, the Institute of aquatic biology of the Chinese Academy of Sciences organized 6 scientists from the United States, Switzerland and Germany to investigate the main stream of the Yangtze River with world - class technology, but did not find the white dolphin. In 2012, a white dolphin was found at the Yangtze River Estuary in Shanghai. The Shanghai aquarium and expert rescue failed. The last captive Baiji dolphin Qi Qi reporter Gao Baoyan Zhang Xianfeng source: Changjiang Daily image natural studio Experts believe that the Yangtze River dolphin may have a functional extinction. After the release of the news, the Time rated the extinction of the Yangtze River white dolphin as four of the ten adults in 2007, the first large aquatic vertebrate that had disappeared on the earth in 50 years, and the first large mammal that had been killed by human activities. Expert opinion: its just a high degree of doubt The source of the photo taken: the Chinese green hair Society The Chinese green hair Association, WeChat, showed that the freshwater dolphin protection campaign, launched by the Chinese green hair Association photographer EPNF, was launched in Wuhu, Anhui in April 13th, and made a major breakthrough in April 18th. The image evidence obtained by Jiao Shaowen was confirmed by an expert, the picture of the white dolphin, which has been lost for years and is recognized as a functional extinction. In April 23rd, the reporter of the Changjiang Daily was informed of the matter. In April 23rd, he immediately joined experts in the Aquatic Biology Institute of the Chinese Academy of Sciences and the cetacean group of Chinese Academy of Sciences, which participated in the identification of pictures, and carefully understood the process of identification of the scene. Experts agree that hope is true and requires public approval and more evidence. The pictures were blurred by the photographers and volunteers. The images were coarser, the important features of the White Dolphin - the dorsal fin had not been seen, and the scenes from the parties were different from that of the white dolphin. Only from this picture is the white dolphin, which should be a white dolphin. The same is true of Tongling freshwater dolphin National Nature Reserve in Anhui. Functional extinction is not one in the wild Although the dolphin was identified as functional extinction by experts in 2006, it was not in the wild. The last captive Baiji dolphin Qi Qi reporter Gao Baoyan Zhang Xianfeng source: Changjiang Daily image natural studio Functional extinction is an objective and accurate description of the living conditions of the living species. The main meaning is that there is no individual in the remaining population, or because of the small population, the disturbance of human activity and the influence of genetic factors, the loss of the species in the natural environment, and eventually to extinction. . Functional extinction is not one in the field. Scientific definition means that the species is destroyed by its living environment, so that the number of the species is very rare, so that the ability to maintain the population reproduction is basically lost in the natural state. The life cycle of the white dolphin is 30 years -50 years. In the early 80s of the last century, there were about 400 fish in the Yangtze River. Before 2006, the Yangtze River dolphin had appeared in the Eight Mile River waters of the Jiujiang section of the Yangtze River. It is more important to protect the natural environment of the black sand bar Only two species of cetaceans exist in the world: the Yangtze River and the Amazon River. Due to the love for the goddess of the Yangtze River, the investigation of folk dolphins in China has been very popular in recent years. The white dolphins graceful posture has made many volunteers become its fans, eager to find the fairy track of dolphin. In the dry season of 2-5 every year, a group of volunteers looking for Baiji live in the black sand island area of Anhui in the history of Baiji. For example, Song Qi, a volunteer in Beijing, gave up his holiday for three years in a row, and organized 2017 folk White Dolphin inspection team at their own expense. He also raised funds online to maintain their daily expenses. Zhang Zhengrong, a journalist from Shanghai, was also a white dolphin fan. He contacted all walks of life to make a field record of the river reconnaissance survey team. China green hair Association and some enterprises not only invested 200 thousand yuan to subsidize photographers to take pictures at Hei Sha Chau, but also offered a reward of 100 thousand awards to photographers of Baiji pictures. The folk expedition team rented an inspection ship to carry on the carpet search along the Bank of the black sand bar. At the most popular time, the photographers had dozens of long cannons on every inch of the river, and many observers assisted the scans of the river. The folk investigation team took more pictures of the Yangtze finless porpoise at Hei Sha Chau. However, experts are of the view that the importance of protecting the natural environment of black sandbanks is more important. The black sand continent is not the main waterway of the Yangtze River. The hydrological environment, the rich biological diversity and other geographical conditions are the good foundation for the establishment of the dolphin protection area, and the relevant government departments should be able to further coordinate the management. It seems that the protection of our ecological environment is still a top priority. We hope our Changjiang goddess will come back to us a day!
