Can a Fish Drown
In this article We share with you if can fish drown in water ? With directories.
If you can't swim and try to get in the water, there is a high percentage of you being drowned, which is suffocation due to lack of oxygen because you could not breathe - of course.
But this happens because we are not prepared to live in the water, so what about fish that live in their natural environment, how can they survive without drowning, or can they drown at all?
Fish breathe through gills, to get dissolved oxygen in the water, and because they live in an environment in which the air pressure is greater than on land, their structure has been formed to suit that environment, and in the event of a lack of oxygen in the water, they are suffocated and drown.
The fish naturally move to the water saturated with more oxygen, and in certain areas the percentage of carbon dioxide in the atmosphere increases, which means that the water absorption of this gas increases, and the temperature of the water body increases, which negatively affects the presence of fish.
In a study on fish diseases of the Arab Organization for Agricultural Development, it was found that there is a relationship between the water temperature and the percentage of oxygen, as the fish become in danger when the temperature rises to 20 degrees Celsius.
The study found that when the water temperature reaches one degree Celsius, the amount of dissolved oxygen in it is 14.7 mg / liter, the percentage of oxygen decreases to 10 mg per liter if the water temperature reaches 10 degrees Celsius.
The need for oxygen varies according to the type of fish, so the comb fish can tolerate a low concentration of up to 4 mg / liter, and the catfish can tolerate low oxygen up to 2 mg / liter, and for trout, the amount of oxygen must not be less than 7 mg / liter, otherwise these fish suffocate and drown.
Suzan Khalif, professor of marine environment in Alexandria, says: Fish breathe through the gill filaments, and the oxygen in the water moves from the mouth to the gills, so the gills are the organ responsible for the breathing process.
Susan continues that if the oxygen is low, it is natural that this leads to the fish suffocating and killing them, and if the gills stop working for any reason, then it is natural that this leads to suffocation, or to be more precise, "drowning".
She continues: There are types of fish, including the shark, that dies and dies by drowning if it stops swimming, so its breathing mechanism is linked to movement and swimming, and if fish are infected with any disease that affects one of their organs, it may expose them to drowning, and when fish die, they float on the surface of the water, as a result of gas emissions Which are formed in the body of the fish during decomposition.

Why don't fish drown ? Density is how heavy an object is versus its volume, bodies denser than water sink and bodies less dense than water float.
Do not drown fish because it can change the density of their bodies. Inside most fish there is a balloon bag. Known as a swim bag, it is full of gas, and the fish can change the amount of gas in the bag so that the density of its body matches the density of the water around it. When the amount of gas inside the bag is very large, the fish will be more buoyant or buoyant.
And fish do not drown even when they are in a state of immobility because the swimming bag works continuously. Here we point out that the shark, for example, does not have a swimming bag in its body to keep it afloat, so it must swim all the time to avoid drowning. By drowning we mean descending to the bottom of the sea, and not necessarily death.
How do fish breathe underwater?
Like other animals, fish need oxygen to breathe in order to survive. We get oxygen by breathing air into our lungs while fish get oxygen from the water and they breathe through their gills instead of lungs. When the fish swims, it opens and closes its mouth constantly, and when it opens its mouth, it closes its gill covers and enters a large amount of water into its belly, then closes its mouth and opens its gill nests slightly. Water comes out forcefully from the gills on the body of the fish. Meanwhile, the oxygen dissolved in the water enters the fish’s blood, and the gas waste from the gills gets out into the water. The fish's gills can be seen at the bottom of the slit-like opening directly behind the head, protected by gill cover and resembling ailerons.

Which fish can live outside the water?
Long-billed fish is found in mud. They are happy to be outside the water, and these fish live in mangrove swamps (tropical trees) located at the headwaters of some tropical rivers, and these fish begin to jump out of the water into the mud when the tide recedes in search of worms, insects or snails that feed on them. These fish breathe by keeping Their mouths and gills are full of water, as they regularly switch between mud and stagnant water to replenish their mouths and gills with a fresh burst of water. This type of fish can also. Like frogs, they take oxygen through their outer skin, and to breathe this way they need to keep their skin moist by soaking in the mud.
Where does the fish sleep?
Fish cannot close their eyes because they do not have eyelids, but they still need to sleep like humans. Some fish lie on the sea floor or bury themselves in its sand, while others shelter in the crevices between the rocks or sleep among the seaweed bushes. In this way, it protects itself from hungry animals that go hunting at night.
The parrot fish lives among tropical marine coral rocks near the surface of the water, and it takes its name from its hard beak mouth, with which it cuts coral blocks to feed on. And the parrot fish sleeps in secret places that show intelligence, as it secretes a transparent mucous bubble around its body like a sleeping bag. And the mucous material comes out of certain glands inside her mouth. The construction period of this thickened sleeping bag takes about half an hour and like that to get rid of it in the morning. Scientists believe that sleeping bags help prevent other invasive fish, such as eels, from smelling them. This way, you sleep in safety.
There is a type of fish known as the lungfish that goes into a deep sleep during the hot African summer, when the swamps and rivers in which it lives dry up. These fish can survive until the rains again. This type of sleep is known as summer sleep. When the water level decreases, the lungfish dig a hole for itself in the mud at the bottom of the water.
And it creates the entrance to the burrow with mud and then turns itself to become the head up, then it secretes around itself a mucous sac similar to the parrot fish, and leaves an opening for its mouth only to be facing towards the surface, and it breathes from the air that comes from the entrance to the burrow and the lungfish has to live in this way for a few months Although it has been known about some of its species that it lives on this pattern for a period of up to 4 years. During this period, this fish lives on its muscle tissue, which is transformed into food. This food remains on the heart, lungs, and the rest of the body alive. These fish have lungs to breathe when outside the water, and they also have gills to breathe when in the water.

Does fish die drowning if you stop moving ?
When watching your aquarium fish in an aquarium, it is not uncommon for you to see that one of these fish does not move, and if it happens and stops do not worry, it may take some rest from swimming just as most fish do not drown if they stop swimming, but the number Few fish must swim in order to be able to breathe, because the fish needs water in order to make their gills able to breathe, let us look at how the fish breathe, when the fish takes oxygen from the water and enters it into its mouth and then flows through the gills and the fish can breathe at that time. Inside the gills are hundreds of gill filaments.
Fish resting from swimming:
Many fish have life cycles, just like wild animals, so we find that some are active during the day and sleep at night, and others do not do that and like to move and be active in the dark, as most fish do not have eyelids and cannot close their eyes, and if they want to rest, they become It is steady and goes down to the bottom and rides a gentle stream, of course the aquarium does not have this kind of currents, but the fish can anyway find themselves a special spot to rest in.
How do fish gills work?
Gills are a tool for oxygen delivery to fish, which is the respiratory organ in many aquatic animals. When fish draw air from the water, blood passes through the gills through tiny blood vessels, and the blood then absorbs oxygen and releases carbon dioxide.
Sharks sink if they stop swimming:
Sharks are a prime example of fish that risk their lives and risk drowning if they stop swimming. The gills of sharks are slightly different from the gills of other fish, and the reason why the shark is different from others is that water does not flow into the gills if it does not swim, and this applies to some other fish Like blue tuna.
In fact, most sharks actually need to continue swimming to be able to survive. If they stop swimming, they will drown, because they do not have the mechanism that allows them to breathe during sleep, as they swim to push water through their mouths where oxygen is extracted.
As a result, when the shark stops moving, the gills also stop getting water and thus stop obtaining oxygen, which is the reason that it is alive. It is really a very stressful job for a shark, is it not? !!
Signs of disturbances in ornamental fish:
As we mentioned before that your fish is difficult to drown if it stops swimming, but it is possible that its normal activity may decrease, here is evidence of a problem and it must be known immediately, many fish start their movement slowly or stop swimming if they are sick If you notice these signs on your fish, you must check for other signs of disease such as a change in the color of the skin or withered eyes, in this case try changing the water, it is possible that this will help revitalize your fish, or you will need treatment such as antibiotics, Sick fish must be separated from healthy fish as soon as possible, to prevent the possibility of any infection spreading among them.
