They protect Qinghai Lake Squid (young people in the protected area (23))

  Figure 1: The staff of Qinghai Lake Naked Ambulance Center is chiseling. Figure 2: Qinghai Lake in winter. Figure 3: Li Chaowei observed the situation on the ice. Our reporter Liu Yurui’s core reading Qinghai Lake naked, is an important species of ecological security in Qinghai Lake.

Emoegen yield, they will collectively travel, find a suitable environment and prosperity.

  In Qinghai Lake National Nature Reserve, there is a group of young people. They combat illegal fishing, build a tour channel for Qinghai Lake naked, and conduct manual proliferation, effectively accelerate the recovery speed of its population.

  Qinghai Lake naked, common famous fish, is an important species for the ecological safety of Qinghai Lake.

  Every year, the Spring and Summer of Spring, Qinghai Lake has to collectively travel, rushed to the Buha River, Shaowei River, Quanji River, etc. mainly flowing into the upper reaches of Qinghai Lake River. In the early years, Qinghai Lake is sharply reduced due to human killing. After decades of continuing protection, by 2020, the amount of naked resource in Qinghai Lake has exceeded 100,000 tons, which was nearly 40 times higher than the beginning of this century.

  Anti-stealing, in the riverside, Jiangxi Township is located in the south of Qinghai Lake, which is a comprehensive criminal investigation law enforcement brigade of the Hainan Tibetan Autonomous Prefecture.

  One day in January, the reporter drove from now on. After ten minutes, they drove the national road, and they entered a mud that was frozen. In short, it went to the Qinghai Lake, and the law enforcement team played on the ice, and they called "on the ice point". I haven’t waited for the reporter from bumps, and Li Chaofei, the law enforcement brigade of the same car, has jumped off the bus, his neck hangs a telescope, ready to elapse. At the National Nature Reserve of Qinghai Lake, Li Chaofei and other three colleagues were responsible for the patrol mission of 186 kilometers of lake on the south bank of Qinghai Lake. One of their main work is to combat illegal behavior against the naked peaks of Qinghai Lake. Li Chauling is 41 years old this year, and the words are very dark.

Long-term plateau work, let him have some vicissitudes.

  "Generally, the criminals are mainly cutting the ice, the number of ice is uncertain from the lake, and the number of ice is uncertain. At least once, the patrol lake players in the South Bank have discovered 12 kinds of ice, the most time It is 180. "Li Chaofei said," Every ice is usually put 1 to 2 plates, and the naked snakes will be difficult to escape.

Because there are more equipment, it is not easy to overlook the iron fenceside of the lake, so the criminals will basically walk the same route as us.

"The 186-kilometer patrol lake line, the east is from the Husong Yangchang, the west to the Buha River, there are 8" Ice Point ", Li Chaowei and the team members are at least 4 at least every day.

  "The first thing to go on ice is to find footprints and ruts.

"Li Chaowei said around," Changxiao is often snowing in the winter night, and the criminals are generally dispatched at night, and it is easy to leave clues. "Walking by the lake, the more like walking into the white desert, turn around, it seems to be far away from the lake.

Li Chaofei said: "Take a few kilometers, the mountains of the lake can’t see it, but don’t be afraid, we have passed in the evening.

"Once, I won the people, the players were dispatched at night, and they were 5 hours behind the cold lake.

"Frozen is not your own.

Li Chaofei smiled. "Summer is not easy. "Li Chaowei told reporters," At that time, a lot of plentiful fish gathered in the estuary area to prepare for the tour, and it was easy to be sturdy, and we lived on the river, not sleeping all night.

"Multiple trials, the construction of the Tour Channel reporter rushed to the stepped fish passage of the Shaowei River, the water has been frozen. Ten levels of steps run through the river, flowing into ice, so that the stairs seem to be smooth and smooth. 6, July, July This is common here that Qinghai Lake naked into a group of prosperous teams traced trace, and is described by locals as "half-river water half-river fish".

  "Qinghai Lake naked a peculiar, and the water quality of Qinghai Lake has a distinctive relationship.

"The Winter Sale of the Technician of the Environmental Protection and Forestry Water Conservancy Bureau of the County," the lake is high, the suppressive gland is mature, even if the ovulation, the infiltration pressure is affected, and the fertilized egg cannot be carried out. Naked in naked drops urged their gonads, in addition, the upper river water is low, and it is also suitable for fertilized egg development. "From the 1960s, the river, the Buha River, Shaowei River, and the Harcum River, etc., the river is mainly infused into the river, which is used for farmland irrigation around the river, but this also blocks the green sea lake. Tour channel, becoming an important reason for the decline in nakedi resources. In 2008, the winter songs and colleagues were in the help of experts, designed the full metal overfish channel.

This kind of fish passage is more than ten meters long, 1 meter wide, 60 cm deep, and put it on the baking dam, put it in the water under the dam, tilting, far from the "riding" on the dam. After the passage is completed, the winter songs and colleagues are guarded by the river all night, and observe the pass rate of the nakedi of Qinghai Lake. After countless test, the appropriate slope was found, but due to narrow channels, the effect of the fish is not ideal.

They immediately started the construction of the second generation of fish channel – stepped fish passage. "Taking the Shaowei River as an example, the original dam is two meters, according to the slope test results, the river dam is decomposed into a taller, the length of more than one meter, the step is designed as a groove, and the naked You can get a break, "Winter Song said," Now, 95% of Qinghai Lake naked can pass.

"" The construction of the stepped fish passage is effectively protected the natural reproductiveness of the green lake in Qinghai Lake. "Winter Song said," This is an important way to solve the problem of decline in naked tract resources in Qinghai Lake.

"Take care of care, strengthen artificial proliferation in winter, 9 o’clock in the morning, the staff of Qinghai Lake Naked Ambulance Center will take the eucalyptus hammer head, and cut a hole in diameter about 3 meters on the frozen outdoor breeding tank. Feeding feed for the dried tens of thousands of lakes.

  Qinghai Lake Naked Ambulance Center is mainly responsible for the monitoring of Qinghai Lake fishery ecological environments and the ambulance of fish germplasm resources in Qinghai Lake. The important part of the work is the proliferation and disclosure of Qinghai Lake.

  "The proliferation and disclusion of Qinghai Lake is selected. It is selected to grow to 10 cm in the ambulance center. It is investing in the Lake River." Saifan Technician Yan Hongfang said, "In order to speed up the recovery speed of Qinghai Lake naked, artificially breed , The work of proliferation is very necessary.

"Mid-April, the peaks around Qinghai Lake melting, the water volume of the lake, the water volume of the lake, gathered to the estuary, starting to trace the tour, the artificial proliferation work begins. The skilled person stands in the water of the ice After selecting a good maturity, after the relevant operation procedure, after hatching the fry, the rescue center is transported to the outdoor pond in the rescue center. "Generally, the newly hatched fish can only eat some small floating plants.

"Yan Hongfang introduced that before and after the outdoor pond, as the fry continued to grow up, the fisher seedlings in the pond rose, and the staff will choose about 70% of the fry transportation to the factory cultivation in the park. .

The supporting machine is opened 24 hours in the circulating water, and the same water area can withstand higher breeding density than the outdoor pond.

In June of the second year, the fry is about 10 cm long and can work.

  According to statistics, since 2002, Qinghai Lake Naked Ambulance Center accumulated more than 100 million tails of artificially breeding naked cargo, and the contribution rate for resource recovery reached 23%. (Editor: Yang Qihong, Chen Mingju).
