Why do some fish not live long when they are caught and put back into the water?

Hello, because the fish swallows the hook, some of them swallow very deeply, hurting the internal organs, even if you put it back in the water, it will slowly die.

The temper of the fish species is not good. Among freshwater fish, most of the fish that like to toss, such as warped mouths and meal sticks, have short lives, and it is not easy to live if they are hooked. Crucian carp and carp have a relatively longer lifespan, especially crucian carp, which can generally live.

Most fish bite the hook and hurt the gills of the fish, and the respiratory organs of the fish are very affected.

Some fish are caught and put back into the water, but they don't live long, the main reason is that when the fish swallows the bait, the hook hooks the gills of the fish, and it has already been injured, so when it is put back into the water, the fish cannot breathe and eventually dies.

Why some fish are caught and then put in the water it does not live long, because after the fish is caught, its oral system has been specially damaged, then the recovery ability of this fish is not as good as the water nature of his original life, then the pH and physiological characteristics are different, he will soon not recognize, just like people put into a new environment, he is afraid that he will get sick in the future, and in the absence of inhibition, he is not mainly caused by environmental changes.

On the one hand, the mouth is already very injured, and the second is that the fish is too frightened after being caught, so it will not live long if it is put back in the water.

1.Fish that bite too hard: Some fish bite the hook very hard, and they swallow the hook directly into the stomach, so that when the hook is removed, the internal organs of the fish have been injured, and the fish will not survive no matter what!

For example, the black fish and the yellow croaker swallow the hook very hard, and when it struggles to lift the fish up, it is basically seriously injured, so it can't live at all.

2.Some bottom-living fish, because they have a swim bladder on their bodies, the swim bladder is a tool that the fish can lift and lower. If the fish are lifted out of the water, the swim bladder of these fish will automatically swell up so that it can surface and then be released back into the water, because there is no pressure on the surface of the water its swim bladder cannot retract, so it can only flutter on the surface of the water, so it will not live long.

This is why many people use a small bamboo skewer to prick a small eye on the side of the fish's body when they release deep-water fish, and pierce its swim bladder so that the fish can return to the bottom of the water. And the small eye heals quickly, so the fish can still come back to life.

3.Some larger fish: This kind of fish is particularly strong in the water because of its relatively large size, and it struggles badly after being hooked, and the scales and gills are damaged, because the current hooks are barbed, and the more the fish struggles, the heavier the damage.

It is very difficult for such a fish to survive after it is hooked. There are also mackerel, mackerel and perch that move on the top floor, which are relatively gas-like and are also fish that die out of the water.

Some fish were caught and then put back into the water, but he didn't live much, and the internal tissues of his fish mouth had been punctured, and they were susceptible to germs, microorganisms, etc., which made the resistance of the fish's body reduced, so he didn't live long.

In this case, when the fish is caught by the hook, it has destroyed its mouth, thus affecting its predation. And in the water, fish can only rely on their own survival ability to maintain and heal. Very few fish will heal. So, it's basically not going to live long.

Hello landlord if the injury is not too big and put back in the water, you can still continue to live. But there are some fish that have struggled so hard in the process of being hoisted up that they have suffered a lot of internal injuries, so even if you put them back in the water, they won't live for long.

Because these fish have been caught, the hook has damaged the mouth of the fish, especially the gills and scales of the respiratory organs, and the fish have also fallen off, and they have left the water for a period of time, and their body functions have been damaged, so they do not live long.

The fish has caused trauma and it is difficult to ** in the water.

In particular, its scale injuries are more difficult to survive. Some of the fish had wounds on their bodies and blood was coming out. Other fish will attack. These are all reasons why it is difficult to survive.

There are many reasons why some fish are caught and put back in the water for a long time, it may be that the fish is injured and dies due to wound infection; It is also possible that the fish have changed the environment and cannot adapt to the new water environment; It may be the emergency response of the fish, which closes itself out of the water and dies.

Because some fish bite very deeply, the injury is serious, and if you put it in the water, it will be bitten by other fish, which is one of the reasons, in addition, like the meal stick, and other freshwater fish have a very short lifespan, after tossing and frightening, so once it is caught, and then put back into the water, it will not live for a long time.

After all, it hurts, and if there is a deep hook, it will hurt the esophagus.

In addition, after being hooked, the fish will be very careful to eat, which will also cause malnutrition and eventually survival of the fittest. It depends on the type of fish. For example, Lingyu will die quickly, and basically can't live a few times without leaving the water, for example, a carp can live longer than Lingyu, for example, Fushou fish can live a long time.

Because he had been in the company for a long time since he was transferred, his scales were almost all gone. So even if it is put back in the water, it will not live for long.

This is because after the fish is caught, there is a wound on his body, and a large number of viruses and bacteria in the water will infect the fish's body through the wound. In addition, because his mouth may be adjusted to affect his eating, even if he is asked to be released, he will not live for too long.

The fish is caught, first of all, his mouth is broken by the hook, resulting in damage, and it may fester, affecting the fish's eating and normal life There is also the fish being caught, and at the same time being frightened, which has an impact on the fish's psychology, because the fish is a more sensitive animal, it will cause their physiological habits to be destroyed, and they will not live long.

The fish that has just been caught dies after a while, and it is the cause of the air pressure, when the fish is in the water, the water pressure is there, and the swim bladder regulates the body. After coming out of the water, the atmospheric pressure and water pressure are different, the fish float is broken, the fish only live for a short time in the summer, the temperature is high, the dissolved oxygen is low, the hot weather is hot, the fish will cost oxygen, just change the water for a while!

But if you don't die, don't put it where the sun can reach you! It is recommended to prepare a basin of water in a basin, so that it is also beneficial to dry it for a day, and you change the water every day, do not dry the water, the professional is called trapped water, there is chlorine in the water, which is very bad for the fish, and will seriously lead to the death of the fish.

As the saying goes, fish farming starts with water! The most common causes of fish mortality are fish disease, lack of oxygen, poisoning and electric shock. The differences between dead fish for various reasons are as follows.

Fish disease: Only species that are sick and have reached a severe level of illness will die. The fish has the basic characteristics of fish disease before death, such as swimming alone, abnormal body color, movement, and swimming style; The number of dead fish is increasing day by day; or environmental changes can reduce deaths; Deaths tend to occur during the onset season.

Lasts for a long time. Hypoxia: Hypoxic dead fish, that is, "turning the pond" and "flooding the pond".

This kind of dead fish, at first, appears as a floating head ("water", "howling water"), and if the oxygen in the pond is not replenished in time, the lack of oxygen will worsen, and death will occur. Generally, the water quality is too fertile, the breeding density is too large, in the high temperature season, such as strong winds, rainfall and other drastic weather, the pond water is mixed and circulating, and it is very easy to cause hypoxia and dead fish. There is a clear order of hypoxic dead fish, first bream, silver carp, then grass carp, herring, and finally carp, crucian carp, if polyculture of green shrimp, mandarin fish and other species that are not tolerant to low dissolved oxygen, they tend to float first.

The duration is shorter, only a few hours from the moment of floating head to death. Aeration measures can save a portion of the fish.

I have an outdoor fish pond in my house, and there are hundreds of fish, big and small, that I catch and play with. Large to koi, grass carp, catfish, yellow mulberry fish, crucian carp, small to white fish, goby, gourd slices. Now they have all bred a bunch of small fry.

So don't take a peek at the leopard and talk about it on paper. Everything has to be seen with your eyes, observed with your heart, and then written and said. Don't let your ignorance affect the ** person.

A false proposition from someone who doesn't know how to fish. If you catch a fish, put it in the bucket and don't put it in the bucket, and when you leave, you will pour it back into the water, and the fish will not die.

Lots of. The small fish I caught were raised in a small pond, and there were more and more fish in the pond. Now there are probably hundreds. Note. This pond was dug last year when the sand was being dug. I saw that the water had not dried up for half a year, so I put it in to raise fish.

There was a carp in England that was caught and released hundreds of times in its life, and it was said that it died from spawning problems.

The loaches are all eaten in the stomach, and they are still a fart, anyway, none of the fishermen I have seen have been released, and I have seen many unscrupulous fishing.

How can there be so many ignorant people? Have you ever fished? The fish in the black pit fish pond are released after fishing, and the fish pit boss buys and then puts them back into the fish pond to sell fish tickets for fishing friends, all of which are alive, called back to the pot fish, and the same is true for wild fishing.

Because the physiology of the fish has been destroyed.

It takes a long time to go ashore, and the fish lack oxygen and the weather, so they don't live long.

Because the environment we live in is not accepted by the fish.

It can be seen that it is a rookie among anglers.

I guess I was frightened and scared. After all, the fish lived a peaceful life and did not jerk out of the water.

Most of them can live, only a few squeamish ones can't. The water you said should be the vegetable pot at home.

It shows that you don't know how to talk nonsense when you pee, those who just put the buckets, and you don't live long if you don't fish.

What kind of ignorant brainless person would ask such a brainless question?

Because the fish gets injured when they catch it, they don't live long if they are left in the water.

This proposition is ignorant and has no scientific basis, and it has a certain pertinence.

Because it is no longer adapted to life in the water.

Crucian carp without lips is often caught.

Because they are out of their own living environment.

No, some fish can still live for a long time.

He didn't live long before he died. Even if the fish are put back in the water, there are many reasons why the fish will die after not being in the water for too long. AlthoughTheoretically, fish caught can survive when they are put into the water, but in real life, the mortality rate of fish released back into the water is very high, eighteen out of every 100 fish die.

At the same time, in the ** data, the fish types counted are all marine fish and freshwater fish, regardless of the environment in which the fish live, the release mortality rate is surprisingly the same. From the perspective of these data, it can be determined that the fish caught will inevitably die if they are put into the water. In some cases, fish that seem to be caught are still alive, and when they are put back in the water, they will die.

At present, there are more than 32,100 species of fish known to mankind, and although the living habits of these fish are not the same, they all have the common denominator of low oxygen tolerance. When a fish is caught, it needs to fight people, and a lot of oxygen is consumed in the process. Including some fish that themselves need a lot of oxygenEven if it doesn't fight a person, it will be deprived of oxygen for a short time after leaving the water, and even if it is put into the water, it will die after a short time.

There are also some anglers who like to put the fish they catch in the net, believing that the net can prevent the fish from suffering from oxygen shortages by placing them in the water. In this case, it can only be said that one factor is overlooked, that is, the space of the net pocket is relatively small, and many fish placed together in the water will still cause the fish to lack oxygen, and they will not live long after being released before they die.

There are two types of hooks used at this stage, one is a barbed hook and the other is a barbed hook. Regardless of the type of hook, it can cause damage to the mouth and the lining of the mouth. Of course, of these two types of hooks, hooks with barbs are more damaging than those without barbs.

The biggest advantage of a barbed hook is that it is not easy for the fish to unhook after swallowing the hook into the mouth.

In this process, the fish will try to swim in different directions to break free, and the barbed hook will hook deeper the more it breaks free. It directly causes damage to the inner wall of the fish's mouth and mouth, which in turn leads to the situation that the fish cannot forage for food, so that even if the fish are released again, they will not live long before starving to death.

In short, even if the fish is put back in the water, it will only live for a short time and will eventually die. Therefore, we call on everyone to prohibit overfishing and establish awareness of the protection of water biodiversity and fish resources. If the method of catching and releasing fish is used to protect the ecological resources of fish, it is recommended to release the fish as soon as possible to significantly reduce the mortality rate of fish.

If the fish are put into the water, some of them will still die, and some of the injured fish will rot and die because of their mouths or infected with bacteria, but some of them will not die, and their vitality will be more tenacious, and they can live in the water for about 5 or 7 days; If the fish is more tenacious, it will not die, but if it falls up again, the fish will be infected with bacteria because of the broken mouth, and it will slowly rot and die.
