What exactly should you do if you want to drown a fish? Can you really drown?

Of course, it can drown the fish.

There are many ways to drown a fish, such as making the water temperature appropriately higher, increasing the salt content in the water, or changing the air pressure, all of which can cause the fish to drown in the water.

To drown a fish, you need to understand how the fish breathe, and most fish do so through their gills.

to absorb the oxygen in the water, so the core of drowning the fish is that the oxygen in the water is not enough to maintain the oxygen needed by the fish, so it will suffocate to death. The way to change the oxygen content in the water is temperature, salinity, and air pressure.

If you want to drown a fish, you can change the temperature of the water, because the dissolved oxygen content of the water is different at different temperatures, and when the fish uses the gills to breathe, the inhaled water contains insufficient oxygen, and the fish will drown due to lack of oxygen for a long time. For example, in reality, when it is very hot in summer, the fish will rise to the surface to breathe, which is because the temperature in the water causes the dissolved oxygen in the water to be insufficient, forcing the fish to breathe out of the water.

The solubility of water to oxygen can also be changed by salinity.

The amount of dissolved oxygen in the water is also different in the case of different salinity, so many freshwater fish.

Once in the seawater, it is difficult to survive.

It is also possible to reduce the solubility of water to air by changing the air pressure, which is more difficult to achieve in reality, but can be proved by real phenomena, such as cloudy days.

, the air pressure will be lower, and many fish will come out to breathe.

So since it is a matter of solubility of oxygen and water, if you want to drown the fish, as long as the oxygen content of the air is reduced, the effect can also be achieved, but the operation will be more difficult, if it is your own small fish tank, the isolation of the air will naturally drown.

What exactly should you do if you want to drown a fish? Can you really drown? Of course, because fish need to inhale oxygen in the water, as long as the solubility of the water to oxygen is changed accordingly, such as temperature, salinity, and atmospheric pressure.

The gills of the fish should be plugged and then the fish should be put in the water, and after a while the fish will drown, which is really okay.

You can sprinkle some salt in the water, so that if you can't breathe some oxygen, you will die. Yes, there are many ways to drown.

Fish cannot drown because fish are very fond of water. The pressure in the body of the fish is very high, and it is impossible to drown the fish.

Most fish breathe with gills, and only when water passes through the gills can the gills extract oxygen from the water. The shark is not a bony fish and can only get more water into its mouth by constantly swimming, so as long as the shark is not allowed to swim, it will drown.

Drowning a fish is essentially making the fish unable to breathe oxygen. Therefore, there are four ways to make a fish unable to breathe oxygen: The first method:

Raise the temperature of the water; The second: sprinkle salt into the water; The third way: change the air pressure; Fourth:

Don't let the fish move.

Put the fish in a plastic bag filled with water, seal it, the air gradually thins out, and the fish whines.

Simply put it in a fish tank and fill the fish tank with air, and soon it drowned

Get out of the water! Haha, forget to adopt.

Everyone knows that fish live in water and are masters of swimming. Humans also imitate the swimming of fish and have made a lot of high-tech equipment. So if someone told you, "This fish is drowned," would you look at him like a fool?

Fish are born to live in water, how can they drown? In fact, the fish will really drown. Next, I will explain to you the scientific truth in detail.

Although fish cannot live without water, fish in the water need oxygen to sustain their lives just like other organisms, but they use their gills to breathe and their swim bladders to adjust their height. If the water they are in runs out of oxygen, the fish will also "braid" every minute. This is a problem that all fish face.

Why do good fish lack oxygen? There are several reasons for this.

First, there may be a problem with the swim bladder. Like humans, fish sinking has a depth limit, and it is not possible to survive at any depth. When the fish sink to a depth that their bodies cannot bear, the strong water pressure will cause the swim bladder to lose its balance, and the instability of buoyancy will make the fish sink deeper and deeper.

There will be less oxygen in deep water, and if the water pressure is too high, the fish will have no choice but to die.

2. A large number of aquatic plants suddenly appear in a normal body of water, and these large numbers of aquatic plants will deplete the oxygen in the water, so that the fish here have no oxygen to breathe at all, and eventually die due to lack of oxygen.

3. It may be that the fish is sick (such as gill rot), so that the fish cannot take in oxygen normally from the water. So that even if there is more oxygen in the water, it will be useless for these sick fish, and they will all eventually suffocate to death.

Fourth, for those fish who are accustomed to living in the deep sea, in order to adapt to the high pressure in the deep sea, the pressure in their bodies is also very great. If they are moved to shallow water for a short period of time, even if they do not leave the water, they may cause relatively high pressure in the body due to the rapid release of external pressure. At this point, they inflate like balloons so quickly that their internal organs may burst and eventually explode to death.

If your fish floats to the surface and opens their mouths to breathe when they are fine, it may be because there is too little oxygen in the water.

Yes, the fish will drown. Fish drinking water is not really drinking water, but filtering the water through the gills to attract oxygen inside, if the pressure in the water is relatively low, the oxygen is insufficient, the fish will die.

No, because the fish can fly freely in the water, and the water is the most suitable environment for it, and it has already understood such an environment with ease.

Yes, there is not much oxygen in the water now, and if the fish had been living in such a space, then they would have drowned.

Yes, there are certain situations in which fish can drown.

No, because the fish has gills to breathe in the water, which prevents it from drowning in the water.

01 If you want to drown a yard of fish, in fact, it is essentially to make the fish unable to breathe oxygen. If the fish can't breathe oxygen, firstly, the amount of dissolved oxygen in the water will be reduced, and secondly, the fish will have problems with the respiratory system: for example, the temperature of the water will increase; sprinkle salt in the water; change the air pressure; Don't let the fish move.

How do you drown a fish? The topic sounds a little ridiculous, the fish itself lives in the water, how can it drown? Tell you, there is a way to be faithful.

Trying to drown a fish is essentially making the fish unable to breathe oxygen. Therefore, if the fish cannot breathe oxygen, the amount of dissolved oxygen in the water will be reduced, and the second will cause problems in the fish's respiratory system.

The first method is to raise the temperature of the water.

If you have goldfish at home, you can throw the fish into the heated water and it won't be long before you drown. This is also the reason why you can't use boiled water to raise fish, boiled water precipitates a large amount of dissolved oxygen at high temperatures, and it is difficult to return to normal oxygen content at room temperature with the change of time, so it is not suitable for fish farming.

The second method: sprinkle salt into the water.

If you don't want to change the temperature of the water, you can also change the salinity of the water and add salt to the water. The salinity in the water body also affects the amount of dissolved oxygen in the water, and the increase in salinity in the water body is accompanied by the decrease in the dissolved oxygen saturation of the water body, which is one of the reasons why freshwater fish cannot run into the sea water casually, because there is a possibility of suffocation.

The third method: change the air pressure.

Theoretically, the amount of dissolved oxygen in the water body can be reduced by changing the air pressure, and the lower the air pressure, the lower the amount of dissolved oxygen in the water. However, it is too difficult to operate in real life, so it is not recommended to drown a fish by lowering the air pressure. In the natural environment, the air pressure will be lower on cloudy days, so the fish will also probe out to breathe.

Ant wheel. The fourth way: don't let it move.

For cartilaginous fish, you can only get enough oxygen by swimming around non-stop. So if you want to drown a shark, in addition to changing the amount of dissolved oxygen, there is another way, which is to prevent the shark from swimming. This happens from time to time in the sea, because sharks are sometimes trapped in the nets and unable to move because they can't get enough water into their mouths and end up drowning.

That's why, when catching sharks, it's important to plug a pump into their mouths and pump water directly through their gills to prevent the shark from suffocating.

Drowning a fish is essentially making the fish unable to breathe oxygen. Therefore, there are four ways to make a fish unable to breathe oxygen: The first method:

Raise the temperature of the water; The second: sprinkle salt into the water; The third way: change the air pressure; Fourth:

Don't let the fish move.

If you understand the role of gills, you know that increasing the speed of the water can drown the fish, and that freshwater can drown the fish in the sea, and that the sea water can drown the freshwater fish, etc.

Fish do not drown. For most fish, they have to pass through water to breathe, and water does not block their gas exchange, so there is no drowning. However, fish can suffocate in the water, and if the water is deprived of oxygen, the fish will die due to disease in their gills or changes in water quality.

At this time, it is necessary to oxygenate in time, use drugs for **, and regularly change the water and clean up the garbage at the bottom. <

Fish do not drown. Drowning is death caused by suffocation when water enters the respiratory system, affecting gas exchange. For most fish, breathing requires water to pass through the respiratory system, their gills, and through the blood vessels in the gill filaments to complete the gas exchange, so drowning is impossible.

Although the fish will not drown, that does not mean that the fish will not suffocate in the water.

1. Hypoxia in water: Hypoxia in water is the main reason for fish suffocation, and the amount of dissolved oxygen in the water is low, which can be due to the large demand for oxygen due to the number of fish, or too few aquatic plants, and the oxygen produced by photosynthesis is not enough. In either case, timely oxygenation is required, along with some aquatic plants.

2. Caused by disease: If the fish suffers from some gill related diseases, such as gill rot, or is invaded by parasites, it will also cause it to suffocate due to hypoxia. In this case, it is necessary to use medication**, insecticides can be used for parasites, and if it is caused by bacteria, it is necessary to sprinkle antiseptic drugs, and also pay attention to disinfection.

3. Changes in water quality: Poor water quality will also affect the breathing of fish, resulting in hypoxia. Regularly remove the garbage at the bottom, but also to feed reasonably, control the amount of feed, usually can splash lime water to improve water quality, but also pay attention to check the pH in the water, if the alkalinity is too strong will also cause breathing disorders, you need to adjust in time.
