What is the reason for fish pond turning over in rural areas?

Fish pond overturning is caused by a lack of oxygen.

The so-called turning pond is a situation in which all the fish in the pond are almost dead, and the stomach is white and floating on the water. Oxygen deficiency is the most common and major condition that causes this condition, so the author will explain it in the first place. Fish are extremely sensitive to oxygen, and a lack of oxygen can cause a large number of fish to die.

The lack of oxygen in the fish pond is mainly related to the weather, and when the air pressure drops due to various reasons, and the oxygen dissolution in the water decreases, the fish will die in large numbers due to lack of oxygen. Especially in summer and during the change of seasons, when the air pressure is unstable, it is easy to cause a lack of oxygen in the water. The author thinks:

At these points in time, effective precautions should be taken. The usual method is to pump oxygen into the fish pond through an oxygen pump when the weather is unstable, so as to solve the problem of lack of oxygen in the water.

In addition to the lack of oxygen, there are also these reasons that lead to pond turning: electricity leakage, chemical pollution, and the breeding of miscellaneous bacteria in the fish pond. Here's a closer look at these points:

1. Leakage can also cause the fish pond to turn over: because water is a good conductor, whether it is the leakage of the underground cable, or because the interface or wire is accidentally put into the fish pond, the fish can be electrocuted instantly, so the fish in the real fish pond are electrocuted, and the pond will be turned over.

2. Chemical pollution can also lead to the overturning of fish ponds: suppose a fish pond is opened next to a chemical plant or a pharmaceutical factory. At one point, perhaps inadvertently and inadvertently, the sewage flowed into the fish ponds, poisoning all the fish.

3. The breeding of miscellaneous bacteria in the fish pond can also lead to the overturning of the fish pond: if the miscellaneous bacteria breed in the fish pond, there will be these harms: make the fish sick, pollute the water quality, and consume the oxygen in the water.

Either of these is enough to make a fishpond overturn. However, this situation is rare, because modern fish ponds are scientifically managed, and the fish ponds are regularly disinfected and sprayed with antibiotics, so miscellaneous bacteria can hardly grow. The above are the factors that cause the pond to turn over.

This is mainly due to the severe pollution of the water in the fish ponds, and it may also be caused by sudden changes in temperature.

This is usually caused by a large increase in the ammonia nitrogen or nitrite content in the water.

It is generally caused by water quality problems, and the most common reason is that there is too much ammonia nitrogen in the water body.

The most feared thing about fish farming in rural areas is to "turn over the pond", which is called turning the pondIt is a situation in which the whole pond of fish is killed on a large scale and cannot be controlled. Once the pond is overturned, it represents more than half a year's energy "in vain", in a rural proverb, it is "over the pond is more miserable than a large overturn". I will talk about the reasons for the occurrence of "pond turning" and how to prevent "pond turning" in production.

One of the reasons may be that there is a serious problem in the water body. For example, the permanganate index and nitrite content in the water quality seriously exceed the standard, resulting in the fish body being "poisoned" and "turning the pond".

The above sedan chair is an analysis of the key points of prevention and management of the situation of "turning over the pond" in rural fish ponds. It is expected that the farms will do a good job of prevention in the planting situation, and immediately adjust the dexterous adjustment according to the actual situation, and the method of human intervention: open the aeration pump, turn on the aeration pump at the right time, and increase the dissolved oxygen value in the water quality.

Fully considering the sunlight exposure, water quality and temperature difference, and the level of photosynthesis of phytoplankton plants, the starting time of the aeration pump generally follows the standards of starting in the afternoon on sunny days, not turning on at dusk, starting in the morning on rainy days, not moving in the afternoon, and starting at night on rainy days.

Therefore, it is suggested that the farms should do a good job of water quality monitoring on time, and take certain effective measures immediately when they find that the water in the fishing pond is green or the water quality indicators are abnormal. According to the water change of the fish tank or the application of microbial agents to regulate the water body, only when the pond water is "good", the fish in the fish pond can grow and develop physically and mentally. Generally speaking, there will be some signs or "abnormalities" in fishing ponds before the occurrence of "turning over the pond".

Those situations must be found by the farms to patrol the pond more often, walk more shifts by the pond, and take a few more looks.

For example, the fish in the fish pond suddenly stopped eating, or there were some of themFish are swaying in front of the pond weakly, or schools of fish are "circling" on the surface of the water at the same time. This kind of small abnormal "behavior" of the fish body is an accusation of their discomfort, and if the farm can deal with it in time and take corresponding countermeasures, it can completely prevent the occurrence of "turning over the pond".

If there is an incident of turning over a fish pond, then tens of thousands or hundreds of thousands of investments will be lost. The incident of turning over the pond was a heavy blow to the fish farmer Hu Laoye, and it was also a devastating disaster. Therefore, rural people liken it to a rollover.

When the dissolved oxygen content of the fish pond water drops to milligrams, the fish pond must be oxygenated quickly and quickly, and the aerator must be started to oxygenate the pond, otherwise there will be a pond accident.

If you want to effectively avoid the occurrence of fondant, you must regularly check the water exchange system of your brother and grandson, reasonably control the density of the fish pond, use some aeration equipment as much as possible, and regularly monitor the water body.

It is necessary to intervene artificially, using an aerator, to increase the amount of oxygen in the water.

When the fish pond has too much feed or polluted water quality (such as pig manure water, rotten grass and other rotten substances) into the fish pond in large quantities, siltation is formed at the bottom of the fish pond, and when the weather is too hot, fermentation produces a large amount of biogas, resulting in insufficient oxygen in the fish pond water, so that the fish float up to absorb oxygen, some fish faint due to lack of oxygen, and the phenomenon of tummy occurs, the phenomenon of turning over the pond occurs in the general fish pond, which will cause a large number of fish to die, causing heavy losses, To solve the phenomenon of turning over the pond caused by this reason, it is necessary to pay attention not to make a large amount of rotten material in the fish pond, and to fish and clean it frequently, and at the same time regularly start the air pump to keep a certain oxygen content in the pond.

It is also possible that toxic substances, such as pesticides, enter the fish pond and cause the pond to turn over. In this case, it is less likely to recover losses.

In addition, it may also be a sudden change in the weather, for example, the weather is sunny and suddenly there are continuous rainy days, resulting in oxygen debt in the upper and lower waters, and it will also be fish turning over the pond, the solution is to actively pay attention to weather changes and turn on the aerator at the right time to avoid the generation of oxygen debt.

In daily life, some people will take fish farming as a profession, sometimes rural fish farming is also a technology, in the breeding must take into account all aspects, then many people will encounter the phenomenon of fish Tong tumbling over the pond, I don't know how to deal with the wheel search, so the following is a brief introduction to the fish over the pond is going on?

1. Weather: Sudden changes in weather will affect the dissolved oxygen in the aquaculture water, resulting in low dissolved oxygen content in the water, which may cause fish to turn over the pond.

2. Pollution: The aquaculture pond is deliberately put into the pond with toxic and harmful substances, resulting in the aquaculture water body can not meet the survival of the fish, resulting in the fish turning over the pond.

3. Management: In the process of fish breeding, there are generally some symptoms when turning over the pond, which is mainly manifested as fish floating head or abnormal activity, so it is necessary to take timely measures to minimize the loss.

Fish turning over the pond is usually caused by high temperature or sudden temperature change in summer, and it may also be caused by pollution of the water in the pond, or due to inadequate management and irresistible factors.

Fish ponds are an important resource for many families and tourists in their lives and tourism. These ponds provide fun, beauty, and edible fish, however, this can cause many problems if the pond is overturned.

First of all, a coarsely dumped fish pond can pollute the surrounding environment, as there may be a lot of fish droppings, excess feed and undigested food residues in the water. These substances can cause water quality to deteriorate and even make aquatic life sick or dead. At the same time, the vegetation and land around the fish pond may also be damaged due to pollution.

Secondly, overturned fish ponds may cause injury or death to the fish. Fish are very sensitive to the environment in which they live, and they are affected when the depth or quality of the water changes. If the fish are covered in overturned silt or debris, they may be suffocated or killed.

If your fish pond is overturned, you should take immediate action. First, assess the extent of the damage and contamination, which may require some professional help. Then, before removing the sediment and debris, you can check for any injured or dead fish that can be taken to the veterinarian or thrown away.

If needed, you should replace it with some new water**, filters, and disinfectants to purify the water. Finally, you should pay attention to the environment around the fish pond and ensure that the water and land are properly treated and protected.

In conclusion, if a fish pond is overturned, do not take it lightly and take swift action to minimize environmental pollution and fish loss.

Summary. I am happy to answer for you, dear, it has an impact, and the remaining fish after the fish turns over the pond have an impact.

I am happy to answer for you, dear, it has an impact, and the remaining fish after the fish turns over the pond have an impact.

Fish turning over the pond is usually caused by high temperature or sudden temperature change in summer, and it may also be caused by the pollution of the water in the pond and the annihilation of ants, or because of inadequate management and irresistible factors.

Does it affect the growth of fish?

Kiss, influence.

What are the implications.

Kissing is to affect the growth and weight of the fish.

Is it slow to grow, not to grow much.

Dear, yes.

Do fry have a big impact?

Kiss, influence.

What to do.

1.Rapid aeration Where there is an aerator, turn on the aerator immediately. 2.

Fish ponds without aeration equipment can be beaten by boats or people swimming in the pool, and small water surfaces can be hit with sticks to hit the water surface for artificial aeration. 3.Replace the water immediately Where the water source is better, all possible measures should be taken to fill the water with new water; Fish ponds with poor water source conditions are irrigated by mechanical pumping or irrigated by two ponds with human bend to increase the amount of dissolved oxygen in the water.

4.The application of alum, quicklime, salt, yellow mud to turn over the pond is not very serious, apply 1 1 5 kg of dissolved alum water or 20 50 kg of quicklime per mu of water surface, and can also apply 2 5 kg of salt or splash yellow mud. 5.

For fish ponds that are seriously turned over, the good fish should be quickly transferred to the pond and filled with new water.

It is necessary to check whether the water exchange system is perfect and whether it is operating normally, ensure the normal operation of the inlet and outlet of the fish pond, and change the water regularly.

Preventing the occurrence of flooding ponds is an important task of pond management. Prevention and rescue work can be done in the following aspects.

1. Pond fish farming, especially intensive high-yield ponds, generally stocked with a large number of fish species and a large density. However, the stocking density must be reasonably adjusted, and it is strictly forbidden to exceed the maximum fish storage capacity of the pond. Do not blindly use a large amount of fertilization to continuously increase plankton mass or a large number of artificial feed to increase the yield, that will only lead to deterioration of water quality, increase the risk of hypoxia, so pond aquaculture should be reasonable and dense, depending on the specific situation of fertilization.

2. The applied farm fertilizer, especially manure, should be used after fermentation; Feeding feed should be scientific and reasonable, and do not blindly rely on more feed to improve production. For ponds with deteriorating water bodies, they should be flushed frequently to reduce the risk of flooding. The silt at the bottom of the pond should not be too thick, and its depth should not exceed 10cm.

For the silt that is too deep in the pond, it must be dried and removed from the pond every year.

4. During the breeding period, without affecting the fertility of the pond water, new water should be added uninterruptedly to keep the water quality of the pond to meet the requirements of fertilizer, liveliness and coolness.

5. Implement the "rotation fishing and release" aquaculture method, implement the fishing of large fish and keep small or catch large to make up for small, and timely pump the amount of fish stored in thin ponds, which reduces the danger of flooding ponds and increases the output of pond fish.

6. Equipped with aerators and water pumping equipment, regularly fill with new water, and regularly start aeration to increase the ability to prevent hypoxia "flooding ponds", and at the same time can timely and effectively treat flooding ponds when they occur, so as to minimize the losses.
