High temperatures in summer. Fish in the fish pond. Die every day. What is the reason?

There are many reasons for dead fish in summer, among which high temperature, lack of oxygen, microbial proliferation, bacterial corrosion, and virus outbreak can all cause death.

Fish are easy to die in hot days mainly due to the high temperature on hot days, low pressure during thunderstorms and cloudy weather, and they are easy to die of lack of oxygen; It may also be due to the fact that hot weather is the most likely season for bacteria to multiply, and they are prone to infection and death; Or because the hot day is the peak season for fish to eat, and the fish are greedy and easy to die.

Fish are ectothermic animals, and their body temperature varies with the water temperature, usually 1 degree Celsius from the water temperature. The temperature in summer is generally relatively high, the temperature of the water will rise after being exposed to the sun for a long time, and sometimes the temperature of the water even exceeds the normal body temperature of people.

Fish tend to die in hot weather, and they are generally farmed at home. The fish raised in the home are generally in a relatively small fish tank, and the area available for activity is not so large, and the water is only twenty or thirty centimeters deep at most, even if the fish swim to the bottom of the water, the temperature can not be reduced much, so the fish are easy to die in hot days. And if it is in the hot summer, basking for an hour or two, especially when the sun is so strong at noon, is not good for the growth of the fish.

In summer, the fish in the fish pond with high temperature are dense and lack oxygen, and the fish are prone to disease. Therefore, in the summer season, when the temperature is high, the fish pond must be oxygenated by an aerobic pump, and the mortality rate of the fish will be reduced.

Sunburned. When the water is hot, there is no cold oxygen, and the fish will definitely die.

There are many reasons for this, and specific problems need to be analyzed.

1. In summer, the weather is too hot and the pond water temperature is too high, resulting in the death of fish caused by lack of oxygen in the water body.

Second, the number density of fish in the feeding pond may be too large, resulting in hypoxic dead fish.

3. It may be fed too frequently, the fish cannot finish eating and the excrement decomposes, resulting in the water quality index exceeding the standard, causing the death of fish in the DU.

Fourth, feed safety, high temperature and humid weather feed is prone to spoilage and acidification, which may also lead to dead fish.

5. Pay attention to the infestation of natural enemies, such as snakes and birds, which are infected with germs and die after being bitten by fish.

Sixth, the water body is too fertile, and there are too many algae and other organisms, which cause death in the old algae water.

7. The high temperature flora is active, and the fish are infected with related bacteria. Wait a minute.

There are many reasons, the water temperature is high, the oxygen is insufficient, and there is no water to supplement the water flow for cooling!

First, the temperature is high in summer, and the thunderstorm and cloudy weather are low, which is easy to die of lack of oxygen;

Second, summer is the easiest season for bacteria to multiply, and they are easy to get infected and die;

Third, summer is the peak season for fish to eat, and fish are greedy and easy to die.

Attention should be paid to water changes:

1. The water should be dried for 1 to 2 days to remove chlorine and eliminate the temperature difference;

2. As long as the water does not deteriorate, draw one-fifth of the bottom every day and add the same amount of new water;

3. The use of oxygenation filtration device can reduce the number of water changes.

Fish are easy to die in hot days mainly due to the high temperature on hot days, low pressure during thunderstorms and cloudy weather, and they are easy to die of lack of oxygen; It may also be due to the fact that hot weather is the season when bacteria are easy to multiply, and it is easy to get infected and die; Or because the hot day is the peak season for fish to eat, and the fish are greedy and easy to die.

1. If the water temperature is too high, it will directly heat to death. It can be shaded, used by a fan or chiller, and increased water exchange.

2. The dissolved oxygen content decreases and suffocates due to the increase in temperature. Dissolved oxygen can be supplemented by increasing water change and air pump oxygenation.

3. Heating causes decay to accelerate ammonia nitrogen exceeding the standard and poisoning. Water can be changed more, feeding can be reduced, and the filtration system can be strengthened.

4. Rising temperature causes a large number of pathogenic microorganisms to multiply and die. It can be prescribed according to the type of disease.

Hello, the biggest reason why the fish in the fish tank are easy to die in the summer refrigeration,It's a sudden drop in temperatureIf the fish don't adapt right away, there will be a lot of death

Suddenly changing the environment in which the fish live requires a transition period, and if the temperature difference between the water is too large, the fish will become sluggish, stop eating or catch a cold, or even die as a result. Therefore, to keep the water temperature stable, the temperature difference should not exceed 3. The most important thing for fish to change the environment is to maintain the original environmental state, water temperature, pH, is the most influential factor, if you can't be sure, you need to slowly pass the water until the fish adapts, so that the fish can survive.

SolutionWhen the refrigerator is turned on, you can turn on the low power first, and then, only for a few minutes, let the fish get used to it. If the temperature is very high that day, then you can turn on the refrigerator for a while, and after 5-6 consecutive days, let the fish get used to the temperature, and you can continue to turn on the refrigerator to work.

Secondly, pay attention; In summer, fish farming should first pay attention to avoiding light, light has the greatest impact on temperature, and at the same time, oxygen pumps should be used to oxygenate at all times, so as to avoid the death of fish due to lack of oxygen. In addition, daily feeding should not be too much, otherwise it will accelerate the growth and reproduction of bacteria, and the uneaten food should also be cleaned out.

The fish in the tank always die in the summer, which may be caused by poor water quality, when the temperature rises, the bacteria in the water grow faster, and the water quality deteriorates faster. In addition, when the temperature is high, the oxygen in the water will also be lost faster, and it is easy to suffer from hypoxia, so the keeper needs to fill the tank with oxygen.

In the hot summer weather, bacteria grow faster than usual, and if too much food scraps and excrement accumulate in the fish tank, it is easy to pollute the water quality, and the fish are more susceptible to bacterial infection, resulting in death. Therefore, the keeper should clean the fish tank frequently in the summer.

When the temperature is high, the oxygen content of the water also decreases, and if the keeper does not add oxygen to the tank or change the water, the fish are prone to hypoxia. It is recommended that the keeper regularly fill the tank with oxygen or install an oxygen pump during the summer when the temperature is high.

In addition, the fish may also die, when the temperature is too high in summer, the desire to eat will be reduced, if the keeper feeds too much feed, the fish may die due to indigestion, so it is recommended that the keeper feed the fish with small meals and frequent meals.
