Li Dazhou, a villager at the Yingjun Village Committee in Xinzhou Town, Danzhou City, usually relies on shrimp farming to earn money to support his family. On the morning of the 13th, he came to the shrimp pond as usual to prepare for work, but the scene in front of him directly frightened him.
Li Dazhou, a villager in Yingjun Village, Yingjun Village Committee, Xinzhou Town, Danzhou City: When I came down in the morning, I found that all the shrimp were dead.
Li Dazhou introduced that this shrimp pond covers an area of about 4 acres, a month ago put about 300,000 shrimp fry of Penaeus vanilla, originally there were two or three months, you can go on the market, did not expect that overnight the shrimp in the shrimp pond, including some of the remaining green crabs in the last season, all died.
Li Dazhou's eldest son: The day before my father came to feed this shrimp, he had not yet found it, and when my father came in the morning yesterday, he found that all the shrimp in this shrimp pond were dead. As soon as I came in, the water turned all green and smelled very smelly.
From the video taken by Li Dazhou on the same day, it can be seen that the water in the shrimp pond is green, and a large number of dead shrimp float on the surface of the water, and the body length of these shrimp is about 5 or 6 centimeters. A pool of shrimp at the good end suddenly died, and everyone suspected that it was not normal.
Li Dazhou's eldest son: There is absolutely nothing related to the weather and water temperature, all the seawater is entered, and then when dad puts shrimp and rice, dad cleans it, and then drains all the seawater in, and then puts shrimp fry.
Li Dazhou's second son: My father has been raising shrimp for more than twenty years and has never seen such a thing. My dad raised these shrimp with a loan, so now I don't know what to do.
According to Li Dazhou's statistics, if this pool of shrimp grows up, according to the current market price, it can probably sell for more than 100,000 and 200,000 yuan, but I did not expect that it would now be lost. Contacting the abnormality of the shrimp pond before, everyone searched for the shrimp pond and found a suspicious place.
Li Dazhou's second son: Seeing that these shrimp are all dead, then look around, and then see here, there are two pesticide bottle caps, and then there is a footprint here.
In view of these circumstances, the parties have reflected the situation to the Xinying CoastAl Police Station in the jurisdiction, and the police have taken samples of the water bodies for inspection to determine the cause of death of these shrimp and crabs.
Danzhou Municipal Public Security Bureau Xinying Coast Police Station Police Officer Huang Yuxiang: After making the transcript materials, we have contacted the relevant departments at the first time and sent the samples for testing. The next step is that if the water quality is tested, there is indeed a situation where pesticides are released, resulting in a large-scale death of the shrimp pond of the police, and we will file a case for investigation at the first time.

In order to help Li Da's family figure out the cause of the shrimp death, the reporter also reflected the situation to the Danzhou Animal Husbandry and Fishery Service Center. Technicians came to the scene to inspect and introduced that the Penaeus vannamei shrimp farmed by Li Dazhou is the main species of shrimp farming in China, while the marine shrimp culture in Xinzhou Town is about 15,000 mu, but sudden death like this rarely occurs.
Danzhou Animal Husbandry and Fishery Service Center Technician Huang Shixiong: According to normal diseases, it will not die like this, the disease is gradual and gradual, a small number of deaths, it is a night to die, a few hours to die, it is impossible. To rule out hypoxia death, because it is shrimp, crab and fish have died, so this is suspected to be poisoning death .
According to the staff, the cultivation of Penaeus vannamei is suitable for aquaculture in Hainan, suitable for breeding in seawater at 20-40 degrees Celsius, and it is usually necessary to use a breeding machine to increase the oxygen content in the shrimp pond and monitor diseases. According to the situation of the on-site investigation, the cause of the sudden death of the shrimp in this large area is not caused by the natural environment.
Danzhou Animal Husbandry and Fishery Service Center Technician Huang Shixiong: This farmed aquatic animals, especially pesticides, are very sensitive to drugs, especially pesticides, because pesticides are pesticides, 0.01 (mg) per cubic body of water, it will appear this phenomenon of poisoning, because we crustaceans, it will also change shells, you are like shrimp and crabs, it is relatively weak, in infancy.
According to the staff, for the aquatic aquaculture industry, the proximity of pesticides and other items must be strictly controlled near the fish pond shrimp pond, and in view of the situation that there may be toxic drugs such as pesticides, it must be taken seriously and handled in advance to avoid affecting the follow-up breeding work.
Danzhou Animal Husbandry and Fishery Service Center Technician Huang Shixiong: Can not start raising immediately, if it is pesticide, toxicity is not eliminated so quickly, at least half a month later, but afraid of affecting other shrimp ponds, you better not drain the water. Through the sunlight, through these natural, it will naturally also, after a month of soaking, it will also fade away.
Technical personnel suggest that after a period of soaking and drying treatment, before starting to release the next batch of shrimp fry, it is best to put a small amount of test products, observe, confirm that there is no abnormal situation, before the normal breeding work, the specific work Danzhou Animal Husbandry and Fishery Service Center will also provide certain technical help.
Danzhou City Public Security Bureau Xinying CoastAl Police Station Police Huang Yuxiang: Our public security organs remind the majority of farmers, usually strengthen their own shrimp pond (management), set up guardrails around the periphery, or arrange people to guard the side, strengthen patrols, if there are unknown personnel near the shrimp pond, to call the police at the first time, if there is a condition, it is better to install a camera monitor.
