There used to be two species of cetacean in the Yangtze River， one was white-flag dolphin， the other is the only freshwater finless porpoise subspecies in the world -- Yangtze finless porpoise. They only live in the Yangtze River. White-flag dolphin has been declared to be functionally extinct， but the Yangtze finless porpoise still has hope…
On November 27， 2014， the official website of the Ministry of Environmental Protection of China announced that in order not to affect the finless porpoise， the Ministry of Environmental Protection has not approved the second phrase environmental impact assessment （EIA） report of the treatment of the waterway of Anqing River. The project which cost 0.5 billion was paused. Once the announcement that project construction gives way to ecological environment was released， domestic and foreign media all reported it eagerly. People feel gratified， and their eyes are fixed on finless porpoise， who is known as "smiling angel" and their living status again.
"There are two reasons why the second phrase environmental assessment report of the treatment of the courses of Anqing River cannot be approved by the EIA： the project is launched in a place where the ecological environment is very sensitive， the project will occupy the important ecological environment of aquatic organisms such as finless porpoise， and the effectiveness of the protecting measures of finless porpoise cannot be ensured." the official website of the Ministry of Environmental Protection of China says. Being unable to pass the EIA makes the project construction institution – Changjiang Waterway Bureau very anxious. Li Qingyun， of director of Changjiang Waterway Bureau said when he received the interview of the reporters of China Youth Daily， " the Anqing River is deep in both ends and shallow in the middle， it stops the ships at the two ends like a bottleneck. For the local government which is in urgent need of economic development， this waterway is very important. If the project is not conducted， the implementation of the objectives of 2020， ‘6–meter deep water to Anqing’ will be affected directly...... it also has relationship to the next step， as for whether ships of 5000-ton level can go to Wuhan after the project 6–meter deep water of Anqing is conducted.
It is also in the Anhui section of the Yangtze where the density of finless is the highest. It is said that there gather about 200 finless porpoises， accounting for almost 40% of the total number of the Yangtze river. "It is because in the past， the speed of economic development of the area was not fast， and there were abundant lakes and tributaries， which could become the refuge for finless porpoises at a critical time." introduced by Zhang Xinqiao， who has attended the 2012 Yangtze freshwater dolphin expedition. The current situation of Yangtze finless porpoise is worrying
Yangtze finless porpoise is the only freshwater finless porpoise subspecies in the world， which is known as the "living fossil" and "panda in the water" of the ecology of Yangtze River. In as early as 1988， it was listed as the second class national-level protected animal of China. In November to December of 2012， by the Ministry of Agriculture of China， the Institute of Hydrobiology， Chinese Academy of Sciences and some other institutions organized jointly the Yangtze freshwater dolphin expedition project， which took 44 days. At that time， Wang Ding， General Commander of the expedition and researcher of Wuhan Institute of Hydrobiology， Chinese Academy of Sciences pointed out，" The speed of extinction of finless porpoise is increasing. The barrier of shipping makes it difficult for finless porpoise to migrate， the construction of water conservancy facilities leads to changes in the hydrological situation of the midstream and downstream of the Yangtze River， the rivers are blocked up， the bottomlands that are suitable for finless porpoise to live reduce. If we do not speed up the pace of finless porpoise protection， they may get extinct within ten years. Therefore， the protection of finless porpoise needs the participation of the whole society."
According to preliminary estimates， with the deterioration of the living environment， the amount of finless porpoise has gradually drops from 3600 in 1990 to 1800 in 2006， with the declining rate of 6.5% per year. After 2006， the declining rate is 13.7%. 2012 Yangtze freshwater dolphin expedition project found that， there were about 500 finless porpoises in the trunk stream of Yangtze River， about 450 in Poyang Lake， 90 in Dongting Lake and 1040 in total. At present， finless porpoise has been listed by the International Union for Conservation of Nature as one of the "critically endangered species".
With the increasing number of people who become familiar with Yangtze finless porpoises， their living situation is drawing more and more attention of people. Yu Daoping is one of the numerous guardians of finless porpoise. He is currently a professor of Life Sciences of Anqing Normal University. At the same time， he is the Technical Director of the Xijiang River finless porpoise rescuing center of Anqing. If you ask him whose call is the most terrible， he will say it is not his superiors’， friends’ or relatives’， but the call from the Fishery Bureau. Because most of the calls from the Fishery Bureau are to inform that the bodies of finless porpoises are found somewhere， and his help with anatomy is needed. It is said that in the past 30 years， Yu Daoping has dissected about 200 finless porpoises. Particularly in recent years， he often finds while dissecting finless porpoises that there is nothing in their stomachs. In addition， their skin has various degrees of injury， "It is for catching fish， that they took the risk of diving into the stone crevices. The anti-flood walls， water conservancy projects all use large blocks， and the mouth of finless porpoise is very short， now they even want to eat the fish in the stones crevices." Thus， it is not difficult to imagine what Yu Daoping sees when he dissects finless porpoises.
Water-concerning projects threaten the life of finless porpoise
Who on earth is the cause of the deaths of finless porpoises？ In this regard， the relevant experts told the reporter that， the main killer who damages the residential environment and fish resources as prey of finless porpoise is large water-concerning projects. Zhang Xinqiao， Project Specialist of the finless porpoise project of World Wide Fund For Nature said in an interview of the media that， in China， when there are national and local construction projects， aquatic organisms often give way for them. For example， in the Xinluo Section of the Yangtze River， a national conservation area has seen 20 to 30 water-concerning projects which needs to be approved and conducted since 2006. At present， the entire Yangtze River Basin has fewer than a thousand finless porpoises. One important reason is the impact of human activities such as project construction.
The threat of water-concerning projects to finless porpoises is permanent， on the one hand， the changes of hydrological condition will cause the degradation of fishery resources， and directly result in foot shortage of the Yangtze finless porpoises， on the other hand， the finless porpoises like reproducing in channels， and places with pits and holes， but during the waterway regulation projects， high strength materials such as stones， concrete， concrete iron and so forth are often used to harden and cover the bottomland and bank slopes， which damages the breeding habitat of finless porpoises directly. After the project is completed， the following intensive shipping will bring a more direct threat to finless porpoises. According to the introduction of Zhang Xinqiao， in the drought period when water surface narrows， finless porpoises which need to breathe， often and squeeze to the same place of ships， thus， shipping becomes the most direct killer. Sometimes these intelligent mammals will hide themselves in the bunkers left by the constructions， however， the situation often occurs that， when the water level drops， some finless porpoises that cannot leave in time are trapped in these bunkers， dying of thirsty and starvation.
