Recommendation for the Protection of the White sided Dolphin Urgent 10

1. Ex-situ conservation of white-sided dolphins: relocate as many white-sided dolphins remaining in the main stream of the Yangtze River as possible to semi-natural environments with similar environmental conditions to the Yangtze River, which are easy to be controlled and improved manually.

2. Protection of the habitat of the white-sided dolphin: Although the environment of the Yangtze River is deteriorating and it is difficult to change this situation in the near future, it is beneficial and necessary to designate the section of the river where the distribution of the white-sided dolphin is relatively concentrated and the environmental conditions are more suitable for the white-sided dolphin nature reserve to protect the existing habitat of the white-sided dolphin and delay the extinction rate of the white-sided dolphin.

Once a breakthrough is made in the ex-situ conservation and rearing of white-sided dolphins in the future, the Yangtze River will still be the preferred location for the reintroduction of offspring bred under rearing or in semi-nature reserves.

Daily activities: The baiji dolphin is timid by nature, easily frightened, generally far away from ships, difficult for humans to approach, coupled with the sparse population and wide activity area, so the research on its living habits in the wild state is very limited.

The baiji dolphin has a constant body temperature of around 36. It has high requirements for water temperature conditions, and often stays in a fixed area for a period of time, and then moves to another area after the water temperature changes. It prefers to move in small groups of 2-16 individuals, and it is common to swim with finless porpoises, especially during mating.

They are accustomed to inhabiting deep waters in the center of rivers, and will also enter the confluence of lakes, tributaries and main streams. Mainly active during the day and resting at night. Timid and shy, it rarely approaches the shore and boats, but often swims to shallow waters in the morning and dusk to hunt for fish and shrimp.

Rely on its own ultrasonic signals to spot food and devour it in a surprise manner.

1.Establish a nature reserve for white-sided dolphins.

2.Reduce the discharge of "three wastes" into the Yangtze River.

Although we can't directly protect the baiji dolphin, we can protect water resources and indirectly protect the baiji dolphin.

Shut down chemical factories along the coast, punish illegal sewage discharge, ban hunting, establish nature reserves, and establish breeding centers.

Summary. Hello dear [smile] The white-sided dolphin, a rare freshwater cetacean, is of great value for maintaining the ecological balance of the Yangtze River system and for scientific research. Because when protecting the white-sided dolphin, you need to protect it by changing their living environment.

And the environment in which they live is also the environment in which we humans live, and protecting the environment in which they live is to protect the environment in which we humans live, which can also be said to protect us human beings.

Only when the living environment improves, these species will not become fewer and less, and finally become extinct, and these species will not become extinct, then human beings can also survive in this environment.

If the environment is not protected, but becomes worse and worse, then in the future, humanity will be greatly threatened.

In our opinion, the white-sided dolphin basically lived in the Yangtze River basin, and in the beginning, it was also very numerous.

These white-sided dolphins live in the waters of the Yangtze River, in addition to some natural substances in the Yangtze River Basin, it is the existence of these animals, the entire Yangtze River Basin has a relatively complete ecological chain, animals have their own predators and eaters, in the process of their reproduction, there are also white-sided dolphins ** food, at that time, the number is relatively reasonable.

Why white-sided dolphins need protection.

Hello dear [smile] The white-sided dolphin, a rare freshwater cetacean, is of great value for maintaining the ecological balance of the Yangtze River system and for scientific research.

And the environment in which they live is also the environment in which we humans live, and the environment in which they live is the environment in which we humans live, which can also be said to protect us from hail and excite human beings themselves.

Only when the living environment improves, these species will not become fewer and less, and finally become extinct, and these species will not become extinct, then human beings can also survive in this environment.

The white-sided dolphin has a history of more than 20 million years, which is far older and rarer than the national treasure giant panda, so it is called the "giant panda in the water".

In recent years, the Yangtze River's fishery resources have been decreasing, the shipping industry has developed rapidly, large-scale water conservancy projects have been built, industrial pollution has become increasingly serious, and the ecological environment of the white-sided dolphin has deteriorated, resulting in a sharp decline in the number of white-sided dolphins, and the population has declined rapidly in recent years.

More than 400 were reported in the early 1980s, which decreased to 300 in 1986, more than 200 in 1990, more than 130 in 1993 and less than 100 in 1995.

In 2000, it was estimated that there were only twenty or thirty white-sided dolphins left, and they were listed as endangered animals.

In December 2000, the people of Anhui Province approved the establishment of the Tongling Freshwater Dolphin Provincial Nature Reserve on the basis of the Tongling White-sided Dolphin Conservation Farm in Anhui Province.

In June 2003, the State Environmental Protection Administration approved the establishment of the National Environmental Protection Yangtze River Key Aquatic Wildlife Conservation Center.

In February 2006, the provincial reserve of freshwater dolphins in Tongling was approved to be promoted to a national nature reserve.

In August 2008, the Tongling Freshwater Dolphin National Nature Reserve Administration was formally established.

The newly established Tongling Freshwater Dolphin National Nature Reserve Administration and the State Environmental Protection Yangtze River Key Aquatic Wildlife Conservation Center implement two brands, one set of people, and the joint office reserve has begun to take shape after years of construction, with a high-quality professional and technical team, and the infrastructure construction is complete, in recent years, it has made certain achievements in the ex-situ conservation of the finless porpoise, and has achieved the world's first artificial management and protection of the finless porpoise.

In addition, the reserve also restores the degraded tidal wetlands in the Tongling Freshwater Dolphin National Nature Reserve to further play the role of wetlands in nurturing species and controlling pollution. At the same time, we should conscientiously monitor the water quality of the Jiajiang River, disinfect it regularly, and limit human activities to prevent the impact of pollutants on the water body, so as to provide the possibility for the recovery of the freshwater dolphin population in the Yangtze River.

The reserve arranges special personnel on duty to patrol day and night to prevent people from stealing fish in the Jiajiang River and then harming the white-sided dolphins. At the same time, the frequency of feeding is increased, which can effectively resist the cold. When encountering a dolphin with poor health, researchers immediately prescribe the right medicine and treat it in time. White-sided dolphins.

White-sided dolphins. Protective countermeasures:

1) Ex-situ conservation of white-sided dolphins: As many white-sided dolphins remaining in the main stream of the Yangtze River should be relocated to semi-natural environments with similar environmental conditions to the Yangtze River, which are easy to be controlled and improved artificially.

Go in. Through investigation, it is found that some of the old Yangtze River channels along the Jingjiang River in the middle reaches of the Yangtze River not only have the environmental characteristics of the main stream of the Yangtze River, such as natural river water and fish, but can also avoid the influence of human activities such as shipping and fishing, which are ideal places for ex situ conservation of white-sided dolphins. After further analysis and comparison, the Yangtze River Tianezhou Ancient Road located in Hubei Province was selected as a national white-sided dolphin nature reserve.

2) Research and reproduction of white-sided dolphins under rearing conditions: despite the protection of endangered species under natural conditions.

It is the most promising measure, but as far as the status of the white-sided dolphin population is concerned, the breeding of white-sided dolphins in captivity has its special significance, the number of white-sided dolphins is too small to be seen in the wild, and the corresponding research is difficult to be effective, and under the conditions of captivity, some studies that are difficult or impossible in the wild are easy to operate effectively, based on this guiding ideology, a conservation measure for the study and breeding of white-sided dolphins in captivity is included in the second of the three major conservation measures.

3) Habitat protection of the baitian dolphin: Although the environment of the Yangtze River is deteriorating and it is difficult to change this situation in the near future, it is beneficial and necessary to designate the section of the river where the distribution of the baiji dolphin is relatively concentrated and the environmental conditions are more suitable as the baitian dolphin nature reserve, so as to protect the existing habitat of the baitian dolphin and delay the extinction rate of the baitian dolphin. At the same time, once a breakthrough is made in the ex-situ conservation and rearing of white-sided dolphins in the future, the Yangtze River will still be the preferred place to reintroduce the offspring bred under rearing or in semi-nature reserves.

IUCN Red List.

Listed as: CR (critically endangered, possibly extinct).

White-sided dolphins. It is one of the only four species of freshwater dolphins left in the world.

The one with the smallest number of remaining states is a national first-class wild protected animal in China. In 1996, it was listed as one of the 12 most endangered animals by the International Union for Conservation of Nature (now known as the International Union for Conservation of Nature, abbreviated as IUCN), and was also listed on the International Union for Conservation of Nature Red List of Threatened Species, the International Convention on Endangered Species (Appendix I) and the National Endangered Species Act of the United States.

Status: The white-sided dolphin is the most endangered cetacean in the world.

The finned dolphin is a mammal of the cetacean order, which is endemic to China and the smallest of the freshwater dolphins in the world. It is a national first-class protected animal, and is currently only distributed in the middle and lower reaches of the Yangtze River, from Zhicheng in Hubei Province to the Yangtze River estuary of about 1,600 kilometers. Feeds on fish, moves in groups, small groups of 2 3 heads, large groups of 10 16 heads.

The population has declined rapidly in recent years. According to reports, there were more than 400 in the early 80s, reduced to about 300 in the mid-80s, about 200 in the 1990 survey, more than 130 in 1993, and less than 100 in 1995, and is listed as a world-class endangered animal.

While some scientists and wildlife managers in China are bravely trying to save the dolphin, it will be difficult to succeed without a bolder and more aggressive approach to conservation. And the extinction of this species would be an irreparable tragedy. Such a reason is sufficient for a large conservation operation.

At the same time, the white-sided dolphin is an important flagship species in the conservation of aquatic animals in China and around the world, and if we do not do our best to protect this species, it will send the message that humans believe that they can afford to lose the precious and irreplaceable components of aquatic life, including freshwater and marine life.

Recommendations: Carefully identify the "hot spots" that often occur in the white-sided dolphin and concentrate all conservation efforts in these areas, including strengthening the implementation of existing fisheries management systems in these areas; While the assessment of a major population is interesting, the first consideration should be to monitor several known populations of baiji, which can be done using flight expeditions or other new techniques; **Identification technology may be used to assist in the implementation of the above measures. Monitoring of individual individuals can provide information to determine patterns of movement, which will help identify important habitats and can be used to determine whether an individual is threatened; Geographic Information System (GIS) techniques and methodologies should be used to help identify protected areas, and the geo-referenced data that needs to be analysed should include:

Fishing activities, the agglomeration of white-sided dolphins, the fishery reserves of the Yangtze River, the natural characteristics preferred by white-sided dolphins (e.g., river confluence, Jiangxinzhou), pollution sources, and the level of vessel activity; In addition to the social scope mentioned in the Action Plan for the Conservation of the Dolphin issued by the Ministry of Agriculture, assistance should also be provided to the residents living in the vicinity of existing and soon-to-be-established protected areas——— especially in areas where established protected areas and where populations of dolphins are common, and where ——— are converted to fisheries; Non-governmental organizations should work together with organizations and local populations to manage conservation in white-sided hotspots, including monitoring and conservation activities.

Measures: 1979: China declares the white-sided dolphin an endangered species 1983: Legislation makes it illegal to hunt the white-sided dolphin.

2007: During a reassessment on 8 August, the white-sided dolphin was labelled extinct in the wild.
