Let "Smile Angel" always smile!Hubei Writing World Freshwater Whale Migration Protection only successful example

□ Chutian Metropolis Daily Journalist Chen Xi Correspondent Zhao Hui Xu Chunyong

Everything has its own will.

In 1972, when the Yangtze River flowed through the stone head of the Swan continent, it was naturally cut straight. The rewritten stroke of God laid a foreshadowing for everything that happened here.

The section of Jiangbei cutting bend is called the old road of the Yangtze River. Since 1990, it has become the arm curvature of the Yangtze River porpoise -5 Yangtze River porpoises began to move to the ground for trial support. At present, the Yangtze Rolls Filk family, which has been breeded by 101, occupied the country's porpoise relocation. Protect the number of species group 2/3.

Recently, the rejoiced Yangtze Rolling Tour in the "Wetland Convention" The 14th Conference of the Conference of the Convention on Wetland. Jimu journalists came to the National Nature Reserve of the Baiji Dolphin of the Yangtze River Swan continent in Hubei to listen to the legend of "the only successful example of the world's freshwater whale relocation protection".

The breeze brushed across the old road of the Yangtze River, and the open water surface rippled. The reporter boarded the patrol boat of the dolphin and observed his old dynamics with the staff.

Hu Lianghui, director of the National Nature Reserve of the Yangtze River, Hubei Yangtze River Swan Island, introduced that in 1992, it was established to protect rare and endangered species such as the White Cycut Dolphin and the Yangtze River Porpoch. In 2007, the White Capricorn Dolphin was announced in functional extinction; in 2013, the Yangtzepin porpoise was listed as an endangered level.

The scope of the protected area includes the first section of the 89 kilometers of the Yangtze River stone (local protection) and the 20.9 kilometers of the old road (relocation protection). Therefore, the average water depth of the road is 4.5 meters. At present, due to the abnormal climate, the water level decreases. The protected area is set up by setting up pumping stations to lead the river water supply to allow porpoons to swim smoothly.

During the speech, a gray shadow jumped into the eyes and disappeared instantly.

"That's the porpoise." Hu Lianghui introduced. The Yangtze River Pills, commonly known as "Jiang pigs", is a small tooth whale with a life span of about 20 years. It looks like a dolphin, with a body length of about 1.2 meters and a maximum of 1.9 meters. The head is blunt, the forehead is bulged, the kiss is short and wide, and the whole body is gray or gray. Live temperament is distributed in the middle and lower reaches of the Yangtze River.

In 1990, the fishermen organized by the Institute of Aquatic Institute of Chinese Academy of Sciences captured 5 porpoons (3 female 2 male) in the Shishou and Jianli River section, and moved to the old road of the Yangtze River. This is the world's first whale relocation protection area.

On both sides of the road, Yanglin, willow tree, etc. are planted, and the green waves are swaying with the wind. This is the result of comprehensive remediation and ecological repair in the reserve.

The cruise went back and forth, and the reporter discovered the figure of the dolphin three times.

Data show that in the past 32 years, the peels of the Yangtze River's hometown have continued to grow: the number of census in 2010 was 28, 60 in 2015, more than 80 heads in 2018, and 101 heads in April 2021.

"The porpoise census was counted after the water came out of the water." Hu Lianghui said. At present, the carrying capacity of porpoons has been saturated in the Yangtze River.

In the first section of the Yangtze River stone that was looking at each other across the continent, the porch porpoise protection results were also very rich. There are more than 20 porpoons inhabited here all year round, and they often appear in groups. "They have been at ease here." Hu Lianghui said.

Trying artificial breeding from the ice disaster in 2008

Fun, blessing, blessing; blessing, disaster.

Swan continent porpoise porpoise cage

In 101 porpoons, some are the results of artificial breeding, and this fate was in the 2008 ice and snow disaster.

There is a porchyle in the reserve with a long, width of 15 meters, and 7 meters deep. It is the cradle of artificially breeding porpoons.

At present, the father and son of the porpoise "every day" and "Meng Meng" live here. In summer, "nanny" Ding Zeliang will feed them small fish at 6:00, 11:00, 16:00, and 20:30 every day. Before feeding. He will disinfect the salt for the small fish.

Ding Zeliang recalled that in the severe ice disaster in January 2008, the old road of the Yangtze River of Swan Island was frozen in large areas, and the porpoons were severely damaged. Among them, the injured male porpoons "every day" and "Zhouzhou" were treated, and were fed in the cage. Soon, "Zhouzhou" was placed in nature.

In 2010, the female dolphin "E''e" came to the cage and lived with "Everyday". In 2013 and 2014, "E''e" had miscarriage twice. According to analysis, it turned out to be a water temperature: the water temperature of the cage is 16 ° C, the water temperature of the upper layer is 37 ° C, and the porphyol is suitable for the water temperature of 28 ° C, so the water body exchange needs to be performed. In May 2016, "E''e" finally successfully gave birth to the female dolphin "Babe", marking the success of the webpage porpoons' artificial breeding, which is the world's first.

In June 2020, "E''e" gave birth to the male porpoise "Meng Meng". In July of that year, after the 4 -year -old "Beibei", after the field training, he returned to the hometown of Swan Island. In August of that year, "E'e" may be frightened because of lightning strikes, refused to eat, and died a month later.

The first porpoise "Babe" for breeding of cages

Ding Zeliang's office is next to the cage. In the refrigerator of the office, there are vitamin C, vitamin B, Huoxiang Zhengqi and other things, which are prepared for porpoons in the cage.

Hu Lianghui proudly said: "Our protected area has obtained two national patents, namely webbage to raise porpoons and porpoons breeding technology."

Fishermen have been transformed into porpoons to protect God

The highest building in the protected area is a 6 -storey high -looking observation tower, and the cameras take care of the surrounding movements. In the room of the video surveillance center, 80%of the protected areas can be seen.

There is also a protection force, the patrolmen of the day and night inspections. The 41 -year -old Wang Yongfu and Sun Haiwen changed from fishermen to dolphin in 2019.

"Fishing affects porphyol food ingredients, grazing affects water quality, illegal reclamation and damage the environment, which is to stop when we inspect." Wang Yongfu introduced. Illegal fishing is also seasonal, with fewer winter and more summer. Therefore, they arranged the frequency of inspection in a targeted manner. In summer, they patrol from time to time in the morning, morning, noon, and evening. The trace of the fish. Sometimes when they meet acquaintances, they are threatened, but they still take photos. Sun Haiwen said that in the past, he was a fisherman, and he could make 70,000 to 80,000 yuan a year. Now he is a patrolman, with a monthly salary of only 3,000 yuan, and he has to make up for farming. "Protect the ecology, you must respond." Sun Haiwen said.

Examination for porpoons

Ding Zeliang also changed from a fisherman to a "nanny". The former fishermen have successively became the "protecting God" of porpoises.

Exchange dolphin improvement of population genetic structure

There are five domestic dolphins moved to the ground. The old lane of Shishou Swan Island is the largest number of porpoons and the most output.

In order to improve the genetic structure of the peels and wealth of the group of peels, the group genes in the peels of peels have begun, and in 2015, the Swan Island Reserve has successively reached the Yangtze River Xinluo Section (Hubei Honghu City, Chibi City, Jiayu County, and Linxiang City, Hunan Province). Hewang Temple, Anhui Tongling and other protected areas, as well as other suitable habitat output to output 24 porpoons. Among them, 18 heads were exported in April 2021, and 8 heads were introduced from Poyang Lake, Jiangxi. In accordance with the "Yangtze Relly Dolphin Rescue Action Plan", the protected area will continue to adopt the Yangtze Rolls output and move in measures to improve the porchye group.

32 years of relay, local protection, relocation protection and artificial breeding, fruitful. Experts at home and abroad unanimously identified that the Swanzhou Reserve has written the only successful example of the world's freshwater whale relocation protection.

At present, the number of porpoons in the Yangtze River is about 1,000. Thirty standing, standing at a new starting point, Hu Lianghui said that the protected area will focus on porpoons and survival environmental protection as the center, improve the level of protection management and science and technology, and create a world small whale relocation protection demonstration base, China Freshman dolphin natural protection education education The base and the export of mass resource output bases in the base of the Yangtze River in the Yangtze River. "The ultimate goal is that the porpoise returns to the embrace of the mother river of the Yangtze River, keeping the" Smile Angel "always smile."
