Unclean waters caused by a large number of dead fish by which department control

When found in the waters of a large area of dead fish, if there are still a large number of fish are not dead, visual inspection of the surviving fish in not too bad condition, then the first time to give the fish to increase oxygen. Practice has proved that, no matter what the cause of the large-scale death of fish, to the fish to increase oxygen to have the opportunity to save as many surviving fish. According to the fish pond area, water source and other characteristics of the water, as soon as possible to deploy a suitable oxygenator, 24 hours non-stop running oxygenator, waiting for follow-up rescue measures.　　Diseases, lack of oxygen due to weather causes such as dull and hot air and storms may cause fish deaths, but it is almost impossible for these causes to result in the sudden and rapid death of a large number of fish, let alone an instantaneous die-off. As experienced farmers, basically can distinguish these scourges, weather causes just need to turn on the full horsepower of the oxygen supply equipment to supply oxygen, without too many remedies; they can judge the cause of the disease can be directly to the procurement of drugs to save treatment, they can not judge the disease to seek help from aquatic medical experts. Other unexplained cases, before the following remedial treatment.　　For the unexplained situation, after the full oxygen supply, to immediately collect water samples and dead fish typical samples, sent to the government animal husbandry and aquatic department testing and inspection, in order to be more reliable, the water samples can be sent to the environmental protection, geology, quality inspection and other departments are tested again. In order to prevent tampering with the testing and inspection because of the interests of all parties involved, it is best to keep enough samples to be used as evidence for possible future claims. Only with the correct test results can further correct remedial measures be taken.　　In addition, if it is a large-scale aquaculture fishery, then it is best to send someone to report urgently to the government departments such as aquaculture and animal husbandry, agriculture, and even directly to the local county and municipal governments, in order to get the attention and help of the relevant departments. Also go to the public security department to report to the police, on the one hand, if it is poisoning and enterprise illegal sewage discharge and other reasons lead to dead fish, due to the police intervention, can provide legal and effective evidence, in order to find the murderer and claim for compensation in the future; on the other hand, if invested in commercial insurance, the future of the insurance claims, but also need to be provided by the police of the legal effect of the documents. Farms with commercial insurance will also need to report to the insurance company so that they can send someone to observe the scene and prevent future claims.　　If there is a large-scale death of fish in a fishing farm, it may often cause a stir and panic in the local area, which will attract well-informed journalists from various newspapers, radio stations and television stations, and once the news is reported, it is likely to lead to other unintended consequences.　　Before the test results come out, if you suspect that a company is illegally discharging water, be sure to send someone to the water source before the news reports come out to take pictures of the company's sewage outlets around the record, take water samples as evidence to prevent companies from destroying the evidence.　　The emergence of a large area of dead fish after the news got out, it is likely to attract a large number of people around the salvage of dead fish. If the fish is dead fish factory sewage or man-made poisoning, the fish is not edible, the public do not know accidentally eat will appear health and life may be jeopardized. Some people in the fishing dead fish will go along with the live fish also fish away, a large number of people fishing in an unorganized manner, but also exacerbated by the death of the fish still alive, these will increase the loss of farmers. Therefore, it is important to be prepared to discourage people from acting rashly.　　No matter what the cause of the dead fish, while doing all the emergency work, we must urgently organize manpower to fish out the dead fish to prevent them from rotting and polluting the water quality, thus causing greater losses. Fished up dead fish, if the death of poisoning, it can only be treated as landfill disposal, must not be arbitrarily discarded, otherwise it may lead to environmental protection department fines, adding insult to injury. If the test results are clear that the dead fish is not poisoned, safe to eat, you can salvage a large number of dead fish for sale, in fact, this accidental death of a large number of hard to sell, the best way to deal with the best is to quickly contact the feed mill, sold to the feed mill, or delayed for a long time the dead fish stinks, no one will want to lah, aggravate the loss.　　Some farmers in the occurrence of a large area of dead fish, in order to reduce the loss of consideration, will be a large number of salvage the temporary unaffected waters of the fish on the market for sale, however, due to the death of the fish event to the market, people panic, it is likely that not only the price of wildly falling and no one asked for, which not only delayed the time of the first aid, but also caused the loss of the normal fishponds. Therefore, do not blindly market large quantities of fish when the market is uncertain.　　　　For static water ponds, when the test results came out to determine that the factory is chaotic sewage or man-made poisoning caused by dead fish, it is necessary to drain all the poisoned water as soon as possible, and then replaced with clean water, and at the same time to join forces with the government departments to urge the factory to stop the illegal sewage discharge, and to claim compensation from them. Large fish ponds are difficult to change the water, not all at once to drain the water and then injected into the new water, you should add water while releasing water. While adding water, put an antidote for the fish.　　If the fish have all died out, there is no need to carry out water change operation, but to carry out immersion pond treatment, for poison and pollutants procurement of specialized detoxification agent soak fish pond.
