a sea cucumbers in the tiger's head cliff, farmers are pumping water, ready to clean up the pool again. The main cause of the high temperature and rainfall dilution of the sea cucumber is the main cause of the loan. Many farmers have lost millions in the 108 km coastline of Laizhou City, Yantai, extending countless sea cucumber pools. Successive years of bumper harvest, farmers have tasted the sweetness. The coastal villagers filled the sea to build the pool and fended off the beach. A sea cucumber pool was built up. Many farmers were still building simple houses on the edge of sea cucumbers, guarding the tender sea cucumbers. In early July of this year, a large area of rain began to appear in our province. The high temperature weather has also been accompanied by the early August, which has caused many sea cucumbers to suffer from heavy losses. In the past few days, reporters have learned that besides Laizhou, Dongying, Jimo and other places also have similar situations. Wen / TU reporter Zheng Zhinan from Laizhou, Yantai

three years of investment harvest is "full military failure"
there are two sea cucumber pools in the old Zhou Dynasty. In the morning of August 17th, the pump is pumping water into one of the sea cucumber ponds. The old Zhou's mother did not go home, and the mother of the old Zhou brought up the sea cucumber with the full pool. "The sea cucumbers were dead and none of the sea cucumbers were all, four thousand or five thousand jin of these two sea cucumbers, we lost 4. 5 million."
Lao Zhou's wife squatted at the side of the pool and looked at the pale green pool water. "Now I can't find one. How can we live together?"
old Zhou went home and told reporters that these two sea cucumber ponds were built in 2010. Basically, they had all the family assets and some loans. Old Zhou told reporters that three years ago, he invested so far, he did not return, originally aimed at this year's market, want to sell a good price, but did not think of the return of blood, "sea cucumber culture is two to three years to receive, three years when the Qianhai Shen Chi was built when the sea cucumber seedlings, just when the time, but now all have not."
old Zhou told reporters that the weight of the sea cucumbers he put in three years ago has reached about 22 every spring this spring. Someone wants to buy it, but he doesn't have to sell it. I want to make a little money by waiting for the sea cucumber to sell again this fall. But before the fall, the sea cucumber in the pond has not been able to catch up. "Some sea cucumbers have become lumps, and some have turned into strong pulp. They are all rotten."
in July this year, the sea cucumber began to appear at the beginning of the problem. It was when the rain continued in Laizhou, the rain lasted for more than half a month. "When the sea cucumbers began to die, I also filled oxygen in the sea cucumber pond with oxygen rods, but the sea cucumber died too fast, and oxygenation did not work at all." The old Zhou sighed and said.
now, the old week is going to clean the sea cucumber pond. "First clean the pool. Wait until the weather is stable. I can't help it. It's a big pool. "
millions of people lost millions of people in
Laizhou Diao Long mouth small Shidao near, there are nearly 10000 mu of sea cucumber pool. On the two sides of the little Shidao highway, one after another, the sea cucumber pond has become a landscape in the bay.
reporter noted that only a few of these sea cucumber ponds have pulled up a small area of sunscreen in the pool, and most of them are exposed to sunlight.
Lao Zhang's family has two more than 30 mu of sea cucumber pond, and the recent high temperature and precipitation also made the sea cucumber of lachang Zhang's "grain uncollected." Lao Zhang built a three cement house near the pond. He and his wife lived here all the year round, looking at the sea cucumber pond. After staying there for a while, he felt a burning pain on his face. Lao Zhang and his wife, under the blazing sea breeze and sea breeze, turned their skin black and red. This is the usual color on the faces of sea cucumber farmers.
Lao Zhang's wife said that the sea cucumber died so much that she could not bear to go near the sea cucumber pond. But at noon, Lao Zhang's wife went to the sea cucumber pond and looked at the pond, though the sea cucumber in the pond was running low. Lao song, a farmer, told reporters that this piece of sea cucumber is a sea cucumber pond built by reclamation, and more and more sea cucumbers are raised. "This little Shidao has nearly 10000 mu of sea cucumber pond, and the whole Diao Long mouth is too much." The old song said that each sea cucumber can produce five hundred or six hundred jin of sea cucumbers per acre. Only the old song family lost millions of sea cucumbers. "Only a few sea cucumbers did not grow, and two or three years of sea cucumbers were over." Lao Song told reporters that among the sea cucumber farmers he knew, millions of people lost millions.
Lao Song told reporters that this year he measured the highest temperature of the sea water reached 33 degrees, and the rain and high temperature this year together became the dead enemy of the sea cucumber, "the original temperature is too high, but there is no such large area of death, this year more rain than the previous year, two reasons only led to the sea cucumber harvest." Lao Song said, after the rain, the salinity of the sea cucumber pool is less than 20 per thousand.
a reporter in Laizhou found that, in addition to the tiger head cliff and Diao dragon mouth, the aquaculture area of the Cui Jia village of Jin Bin street, Zhu by the aquaculture area of the open sea cucumber culture also suffered huge losses.
reporter survey
precipitation and high temperature superposition caused the death of sea cucumber
in the hall of the Laizhou Oceanic and Fisheries Bureau, posted the high temperature yellow warning issued by the Laizhou Meteorological Bureau in August 5th. The staff of the Fisheries Department told reporters that the average temperature of the sea water reached 29.5 degrees centigrade this year, 0.6 degrees centigrade higher than the average sea water temperature of 28.9 degrees centigrade last year. The reporter learned from the Laizhou marine and Fisheries Bureau that the average seawater temperature in August 17th reached 29.7 degrees Celsius.
the staff of the Fisheries Department told reporters that the main cause of the massive death of sea cucumbers this year was the rising temperature of the sea water, the heavy rainfall this year and the decline in salinity of the sea water, which led to the death of the sea cucumber. Sea cucumbers cultured in ponds can be cooled by underground water and ice, or by shading nets to relieve high temperatures.
the staff also said that Laizhou's sea cucumber can be harvested in rotation mode for two or three years, producing about 3000 tons a year. The sea cucumber's death this year will have an impact on the output of sea cucumber in the next two or three years. The specific loss situation, the staff member said, is still in the statistics.
reporters learned from the Hydrology Department that from July 1st this year, as of five p.m. yesterday, the precipitation in our province reached 388.2mm, which is 34.6% higher than that in the same period. The hot weather also lasted from the early August to the present.
local fishermen told reporters that in the process of sea cucumber breeding, when the water temperature exceeds 20 degrees, sea cucumbers will enter "hibernation" state, do not eat or drink. Once the water temperature exceeds 28 degrees, sea cucumbers are easy to die. At the same time, the increase of precipitation leads to the sudden drop of salinity in the pool, the lack of oxygen at the bottom of the pond, and the deterioration of the culture environment, which greatly increases the risk of marine culture diseases.
at the same time, the reporter found that a large number of water systems into the Laizhou Bay of Bohai, 19 fresh water from the Laizhou bay into Bohai, a large increase in precipitation also easily affect the sea water salinity of the coastal areas. In addition, some aquaculture farms have expanded the sea cucumber pond to the sea, and also affected the replacement of sea water in the sea cucumber pond, which has affected the healthy growth of sea cucumbers.
the emergency measures
similar situation related departments have issued preventive measures
reporter survey found that in addition to other areas, there are many other regions that have caused the massive death of sea cucumbers because of high temperature and heavy rainfall.
reporter noted in the dynamic columns of the official website of the Provincial Department of ocean and fisheries, the recent phenomenon of the death of such sea cucumbers appeared in Jimo, Binzhou, Binzhou, Wudi and some cities in Yantai and Weihai.
in August 16th, the Fisheries Department of the Department of marine and Fisheries of Shandong Province issued the emergency prevention measures for the high temperature disaster of Shandong province. The measures indicated that the death and skin of the cucumbers are mainly caused by abnormal changes in the water environment caused by extreme weather, and do not belong to the explosive diseases. Oxygen agents, substrate modifiers and anti stress preparations. According to the forecast of the meteorological department, the recent hot and muggy and wind free weather will continue, the influence may be further expanded, and the producers of the cucumbers can take the harvest and reduce the loss.
