According to an expert from the Jiangxi Provincial Academy of Sciences, the died porpoise was discovered by a donkey friend on the evening of September 3, and then the porch corpse was transported away by the Jiangxi agricultural department. According to reports, this died porpoise has no trauma and has been frozen. Experts will dissect it to determine the cause of death.

Pretellasia is a national first -class protection of wildlife. According to the data, the results of the Yangtzepin ecological sciences in 2017 showed that the number of porpoons in the Yangtze River was about 1012 heads, of which 457 Poyang Lake heads. The death of porpoises is sad and worrying. Some netizens said that fishing in the Yangtze River Basin was originally restless. Who knows that it is difficult to encounter drought again, and the fish is too difficult.

According to reports, although the death of porpoons is not yet determined to be related to the drought of Poyang Lake, the negative impact of drought on porpoons is very obvious. Since the beginning of this year, Poyang Lake does have a few porpoons have died. There are both natural reasons and non -natural reasons. Most of the non -natural deaths have died for stranding the cause, and no porpoise death caused by artificial factors.

Fish is inseparable from water. The middle and lower reaches of the Yangtze River have encountered a rare "flood season" phenomenon this year. Many water levels are the lowest in history since hydrological records, and it is inevitable to worry about the fate of fish.

Earlier, there were media reports that during the drought, "Dongting Lake's retreat was too fast, which caused many fish to retreat into the main river channel and was trapped in some small ponds, causing many fish to die in oxygen."

On August 22, the staff of the State Nature Reserve Management Bureau of Dongting Lake, Hunan, said that the water level of Dongting Lake retired to the position of previous winter at the end of July. The water area was significantly reduced. Essence If the drought continues to develop, the water level of Dongting Lake will not be effectively supplemented, and the death of fish may increase.

A staff member of Yueyang Junshan Fisheries said that this is the worst drought in Dongting Lake in the past 50 years. Recently, their main work is to inspect the unattracting ponds in the Lake of Dongting. After the dead fish are found to be salvaged in time, and then buried the dead fish concentrated to prevent the water pollution.

According to reports, since the drought occurred in Poyang Lake, the local porpoise protection department has adopted the sensitive map of the porpoons to strand the water in the relevant cities and counties, put the small fish to supplement the porpoise bait resources, and increase the propaganda and protection of camping enthusiasts and fishermen. Response measures to overcome the adverse effects of drought on porpoons.

It is necessary to strengthen the protection of porpoons, fish and other aquatic animals during the dry period. The Yangtze River Protection Law clearly stipulates that the relevant watershed management agencies of the Water Administration Department of the State Council shall incorporate ecological water into the annual water scheduling plan to ensure the demand for basic ecological water for rivers and lakes, ensure that the ecological flow of ecological flow during waters and fish spawning periods, and the water volume of important lakes. And water level. It can be seen that the survival of fish that protects the dry period is the meaning of the should be the meaning of the topic and the legal obligation.

In addition to ecological water adjustment, relevant measures can also strengthen inspections of key fishery waters, timely help or rescue stranded aquatic animals from being trapped, and prevent illegal capture activities of "taking advantage of the danger of fish".

According to reports, due to the lack of water body during the dry period, porpoons move to deep water in the deep water area, the water areas are easy to cross and the shipping waters are crossing, and the accidental arrests or past ships cause pollution. Essence

Poyang Lake's death of death in the foundation is also worrying, which is also a warning. Related parts must take further measures to protect this precious species as much as possible.
