It’s easy to take fish for granted “Can fish drown”. You forget how impressive it is that they manage to live in an environment very different from ours. When thinking about the life of a fish, many questions arise like ‘ how do fish mate ? ‘and’ do they sleep? ‘
The common expensive people of Anther ask 2: “Can fish drown ?”
Fish need oxygen just like humans do, but they don’t seem to live in water, so they can drown. They have adapted gills that allow them to extract oxygen from the water , so is it possible to drown when they can breathe water?
This article will investigate the question by looking at important things like whether the fish have lungs, how the fish breathe and much more.

1. Do fish really need oxygen?
As human beings, we need oxygen to breathe ; fish are no different. Instead of taking oxygen from the air like we do, they collect dissolved oxygen from the water while swimming.
There is much more oxygen in the air than in water. This makes it much easier to get oxygen when living on land, but fish have developed gills that allow them to survive in water.
Breathing water has its problems , the salt levels of the water can vary a lot.
- Saltwater fish absorb a large amount of salt while breathing because it is in the water. As a result, they need a special system to remove excess salt from their body.
- Freshwater fish have the opposite problem. There is not much salt in the water, so they need a mechanism to retain as much of it as possible.
Fish need oxygen for the same reasons humans do. Without it, they will struggle to breathe and eventually die. Oxygen combines with other elements to create proteins and even form new cells.
By breaking down food in the body , oxygen is used to convert and store its energy. This energy is used in all active processes in the body.
Fish do not need as much oxygen as we do, as they are cold blooded. Warm-blooded animals need extra energy to keep their bodies warm. Fish do not need this energy , so they can survive on less food and oxygen.
There is a finite amount of oxygen in a body of water. The larger the mass of water, the greater the surface area and, as a result, the more oxygen.
In an aquarium, this can be a big problem. There is only a small amount of water, which means you can run out of oxygen quickly. This is just one of the reasons tank size is so important .
Aquarists can use plants to introduce some oxygen into the tank while they photosynthesize.
Air pumps are also useful as they bring oxygen-free water to the surface, forming a small circulation.
This aquarium air pump works in total silence in the aquarium, it is a 4 foot design against jumping and helping to stop vibration. It has an air compressor with advanced air compression system, shock absorption and design.
It has a 1.8 L / min high air outlet rate. Low energy consumption and efficient energy saving.
2. Fish have lungs and what are the organs of the maze?
Fish do not normally have lungs. Most of those you will ever see or hear will have a pair of gills on each side of their body; however, this is not the case for all fish.
There is a group of fish called Lungfishes. As you might guess from the name, they have air-breathing lungs instead of gills .
They are a small group of six freshwater species that can only be found in Africa, Australia, and South America.
African and South American species can survive the desiccation of their habitat by burrowing into the substrate and entering a state similar to hibernation. They do this by slowing down your metabolism to 1/60 of its normal rate.
Lungfish are not the only fish that can breathe air, some have a labyrinthine organ. This organ acts like a lung, allowing fish to take in oxygen from the air instead of the water. Not usually present in juveniles, they start with gills and then develop labyrinthine organs .
Many aquarium fish have labyrinthine organs, such as kissing gouramis and crow-tailed bettas . While breathing air is a primitive trait for fish, it can allow them to live in waters that no fish breathing in polluted water could survive.
Most places in the water are perfectly safe for fish to breathe if healthy and fit, so they don’t need lungs to breathe air because there is enough oxygen in the water.
Instead, fish have gills , which are perfectly adapted to collect this oxygen.
One of the ways to achieve a healthy environment is to reduce organic contamination of the water and favor the cycling process with this natural soil made of neutral clay minerals.
This product prevents the soil from compacting and gives countless benefits to the rapid rooting of plants, providing nutrients to their roots.
3. How do fish breathe and get oxygen?
Before answering the question “can fish drown?” we must observe how fish obtain oxygen and how they breathe. Since there is less oxygen in water compared to air , you need more efficient gas exchange surfaces to collect it.
Fish have gills that can absorb oxygen when it is only 5 parts per million (ppm). We breathe air, 21% of which is oxygen (210,000 ppm).
However, it is not just about efficiency, gas exchange surfaces (such as gills and lungs) must be able to cope with the environment it is in (air or water). For example, our lungs can force air in and out, but we would suffocate if the water filled them.
So how do the gills work ? Well, first of all, water has to pass through them, which is controlled by the operculum (this is a flap of skin that acts as a boundary between the mouth and the gills). The fish lowers the bottom of the mouth. This makes the pressure in the mouth lower than the pressure outside, so water is sucked in.
When the fish lifts the floor of its mouth, the internal pressure becomes higher than the external pressure. This causes the water to flow out of the mouth through the operculum and through the gills.
If you have fish at home you can see this happening, the operculum moves with each breath. This view is one of the many reasons to have fish .
The gills require a large surface area to extract oxygen from water.A larger surface area means that as much water as possible can come into contact with the gills for oxygen to diffuse.
When water comes into contact with the gills, oxygen is transferred from the water to the blood through the edge of the lamellae. Each gill arch supports rows of filaments and lamellae, creating an appearance similar to an automobile radiator.
Gill anatomy can get a bit confusing, but here’s a basic overview .
Fish require a suitable environment to breathe and the living and cleaning bacteria biologically reduce the water in the tank in an active and natural way, ensuring a healthier and cleaner aquarium for longer.
It keeps the filter biologically active and keeps it clean for a longer natural time. This product stops the actions in the tank of ammonia, nitrite and organic contaminants from fish excrement, food residues and dead living beings.
Eliminates dirt on the filter, promotes bioactivity in the substrate, prevents deterioration and reduces maintenance.
4. So can fish really drown?
With humans, when water enters our lungs , we cannot get oxygen from it, so we cannot breathe and therefore we die.
However, we have already learned that fish can extract dissolved oxygen from water, so fish are physically unable to drown .
If the fish are removed from the water, they will die, but not by immersion or inhalation of water, so they do not drown.
If there is not enough dissolved oxygen in the water, they will die because they cannot breathe. One could argue that the fish has died from “water immersion and inhalation “, because the inhaled water does not contain enough oxygen. However, this does not fully meet the definition.
So if you’ve wondered if fish can drown , the answer is probably no.
A more accurate term is probably that fish “suffocate” when there is not enough oxygen to breathe. For suffocate it is defined as “dying from lack of air or inability to breathe.”
5. Choking and drowning fish
Algae blooms in a river can reduce the amount of oxygen available to fish in the water. When the fish are out of the water, they still have access to oxygen and in a much higher concentration. You may wonder what causes their death if they can still breathe. Well the answer is that they cannot breathe, but it is not due to a lack of oxygen.
They can’t breathe because the gills aren’t designed to process air , but that doesn’t mean they can’t. The problem is that the air dries them and they can no longer function properly.
It’s like being dehydrated. When it lives in water, a fish’s body remains wet . Since the gills are designed to be wet, they don’t work if they dry out without water.
A fish can suffocate both in water and out of it. There are many ways this could happen. Any damage to the gills will reduce their efficiency in gathering oxygen, potentially to a point where they can’t get enough to survive. The damage could come from fights or illness.
Other causes of suffocation are things that lower the oxygen concentration in the water. An increase in population size is a good example, more fish are breathing and consuming oxygen.
Oxygen can be depleted if it is not replenished quickly enough. In an aquarium, this can happen quickly because they generally contain a very small body of water. In a natural environment, pollution can cause rapid deoxygenation of water that cannot be replaced quickly enough.
If we are critical, the fish cannot really drown ; but taking a fish out of the water is similar to putting a human in it.
In both cases, the subject cannot breathe in the new environment. The gills and lungs are designed to be used in water or air , and they are much more efficient in their natural habitat than the other.
By considering the word “drown,” you realize that fish do not die from inhaling water . So while fish cannot drown, they can go through a similar experience when they run out of water or oxygen.
