Why do the fish die when they go ashore, and do the fish die if they leave the sea?

The reason why the hairtail fish "dies when it comes out of the water": after the hairtail fish is quickly caught ashore, the external air pressure becomes smaller, and the internal pressure is still very large; The extreme pressure difference causes oxygen and nitrogen in organs and tissues to precipitate out of the blood, blocking blood circulation and even causing organ rupture, resulting in the death of hairtail fish (commonly known as "decompression sickness").

Since we talk about hairtail, let's make a recipe for hairtail:

Pan-fried hairtail] Ingredients] hairtail, eggs, flour, green onions, ginger, Sichuan peppercorns; Refined salt, cooking wine.

Steps] Step 1: Select the hairtail with firm flesh and bright appearance, remove the internal organs and wash them, then cut them into sections and drain them for later use.

Step 2: Shred the green onions and ginger for later use.

Step 3: Put the hairtail fish into a basin, add cooking wine, refined salt, Sichuan peppercorns, green onion and ginger shreds and stir well.

Step 4: Beat in an egg, add an appropriate amount of flour, and mix well. Evenly hang the fish with egg powder batter. Marinate for an hour.

Step 5: Before putting into the pot, pick out the green onions, ginger shreds, and peppercorns, and put the marinated hairtail segments on a plate.

Step 6: Boiled a little oil in the pot, the oil temperature is 6 into the hot into the hairtail section, after the outside is set, change to medium-low heat and fry, repeatedly turn over to make the hairtail section evenly heated, fry until golden on both sides, and then dip it in pepper and salt to eat.

Cooking tips:

1. Put the pot in the pot at high oil temperature to instantly shape the outside of the hairtail and achieve the purpose of non-stick.

2. After the outside is set, turn to medium-low heat and fry. The surface of the high-temperature fried hairtail, and the inside of the low-temperature fried hairtail.

3. Wrap the egg batter before frying the fish, which can make the hairtail section produce a crispy flavor and can also be used as a heat insulation material.

Protects the tender flesh of the fish.

Fried hairtail, some people coated with starch, some people coated with flour, in fact, it is not delicious, teach you the most fragrant method. This fragrant fried saury is ready, hang the whole egg batter, no pot will stick to the pan, the charred and crispy fish meat is tender, it is really satisfying.

Because the water pressure in the deep-sea area is very large, the hairtail fish living in the deep-sea area has adapted to this water pressure, and once the fish is fished ashore, the internal organs of the hairtail fish will suddenly become less due to the pressure, so the hairtail fish caught ashore are dead.

It's true that the fish will explode when they come out of the water, and they will die when they come out of the water. Hairtail is a deep-sea fish.

It is also a kind of fish that we often eat. Hairtail fish is delicious whether it is braised or fried, and there are relatively few fish bones, and deep-sea fish is very nutritious, so it is very suitable for children. However, it is rare to see live hairtail, and the hairtail that you can buy is usually frozen.

The hairtail we bought looked similar to other fish, but it was actually very beautiful when it was alive, and it had colorful waves on its body. <>

However, it is rare to see a living hairtail, because as soon as the hairtail fish comes out of the water, it dies immediately. Because the hairtail fish lives in the deep sea, the water pressure in the deep sea is very large, so after they are caught, they have no way to withstand such a low air pressure on the coast, and their bodies will explode. In fact, self-explosion is just a relatively exaggerated statement, because everyone has the impression that the self-explosion is without bones, but it is impossible for hairtail fish to have no bones, because everyone still has to eat it.

Therefore, the hairtail fish that everyone catches will basically crack a little bit, but there will be no special damage. However, the hairtail we buy at the seafood market rarely bursts, because everyone now chooses to breed the hairtail in order to increase the production of the hairtail. And not all the treatment is deep-sea fish, because the ** with fish is very cheap, if it is really a deep-sea fish, then everyone has to dive into the deep sea when fishing, which is very dangerous, and for the physical fitness of divers.

It's also a big test. In this way, the cost of hairtail fish will definitely increase, and the ** of hairtail fish will definitely not be as cheap as it is now. <>

Therefore, the hairtail fish we eat is generally a hairtail fish that lives in shallow water, because there are many types of hairtail fish in shallow water, and there will be no self-explosion. The treatment of shallow waters will also be easier when fishing, and there will be no complete hidden dangers for fishermen.

Ribbon fish is not really out of the water will explode on its own, the species of ribbon fish inhabit different sea areas, generally we catch shallow sea ribbon fish, so when out of the water will not change much, but there will be a lack of oxygen; The hairtail fish will really die as soon as it comes out of the water, because the air pressure in the environment where it lives is large, and when the hairtail fish is caught and brought out of the water, the pressure in the air is too small, and the hairtail fish cannot withstand the pressure, resulting in the rupture of the swim bladder inside the fish's body.

Hairtail fish really explode as soon as they come out of the water, because they live in relatively deep water, and the air pressure in the water is different from that on land. If you really get out of the water, you will die.

It will not be out of the water, and it will not die as soon as it comes out of the water, and the hairtail fish caught in the sea will not be immediately **, nor will it die immediately.

Yes, hairtail fish will die once it leaves the water and rot within three hours, so refrigerate it immediately after purchasing it.

It is not only the seawater that causes the fish to die when they leave the water, but also the changes in the atmosphere in the water. Many deep-sea fish will even be squeezed out of the internal organs after they are caught, and the process of raising them is very difficult. They have a unique habit of swimming in the near sea during the day and sinking to the bottom of the sea at night, which has certain requirements for water pressure.

Therefore, in daily life, many farms are reluctant to raise hairtail fish, and most of them are caught from the deep sea.

It is not a deep-sea fish, but when it reaches the sea level, the pressure decreases and the internal organs break and die.

When the fish reaches the surface of the water, it dies because the pressure becomes smaller.

Yes, strictly speaking, it will die in shallow seas.

Because the hairtail fish was originally a fish living in the deep sea, the pressure in the deep sea is generally relatively large, and the hairtail fish that is accustomed to living in a high-pressure and strong environment will become lower due to the pressure on the sea surface after being salvaged;

The swim bladder that controls the rise and fall of the body of the hairtail will burst, and the hairtail will soon die. Therefore, freshly caught hairtail is cleaned and stored in a frozen environment, and only frozen hairtail is seen in the market, but there is no live hairtail.

The live ribbon fish is shining silver in the water, and its body swings quickly and slightly when swimming, which is very graceful. After the hairtail fish is fished ashore, it can survive for several hours, and it is also very active at this time, and the twisting is also very violent.

Hairtail is a deep-water fish that lives at a depth of 40 to 50 meters below the surface of the water, as is the yellow croaker.

Hairtail fish is a fish that lives in the deep sea, and the deeper the water, the greater the pressure, so the pressure in the body of the hairtail fish is equivalent to the pressure in the deep sea.

When the hairtail fish is caught by us, because the pressure of the outside air is much smaller than that of the hairtail fish, when the net is off the water, because the pressure in the air is too small, it can not withstand this pressure at once and cause fatal injuries to the inside of the fish body, such as the sudden expansion of the swim bladder to rupture and die quickly.

Hairtail fish bears huge water pressure underwater, but there is also a pressure on the water that swells outwards in the body, so it will not be flattened, and the atmospheric pressure is much smaller than the water pressure, there is a pressure difference, the air pressure is small, and the pressure in the body of the hairtail fish is large, so the pressure in the body of the hairtail fish rapidly expands outward, and the hairtail fish dies.

Because the pressure of the sea and the land are different, the hairtail can only adapt to the pressure of the sea, and once it reaches the land, the pressure is too small and the abdomen distends and dies...

Because hairtail fish live in deep water.

Adapted to pressure.

Due to the low pressure in the upper part.

So if you don't adapt, you're dead.

Hairtail fish is suitable for living in water with high pressure, but once it hits, the pressure becomes smaller, so the body cannot adapt and finally dies.

Hairtail fish is a deep-water fish in the ocean, which is subjected to tremendous water pressure underwater, and also has outward pressure in the body to fight against water pressure. When the hairtail is caught on the water, the atmospheric pressure is much lower than the water pressure, and the external air pressure of the hairtail is small and the internal pressure is high. At this time, the pressure in the body of the hairtail fish will rapidly expand outward, and eventually the internal organs will be broken, and the hairtail fish will die.

Why are all hairtails dead?It doesn't matter if we go to the supermarket or the seafood market, the hairtail fish is dead. All other fish are alive, why are they all dead? This is because hairtail fish is a deep-water fish in the ocean, which is subjected to huge water pressure underwater, and there is also outward pressure in the body to fight against water pressure, so it will not be flattened.

When the hairtail is caught on the water, because the atmospheric pressure is much smaller than the water pressure, there will be a situation where the external air pressure of the hairtail is small and the internal pressure is large, at this time, the internal pressure of the hairtail fish will rapidly expand outward, and finally rise through the internal organs, so the hairtail fish will die.

Can you eat a fish when it dies?It's not good to eat dead seafood, but can you eat dead hairtail? Of course, you can eat it, but you can't eat live hairtail at all. Generally speaking, hairtail fish are caught and frozen directly in the freezer.

It's all frozen, and the ones you buy at the supermarket are even frozen, so you have to thaw the hairtail fish first. The belly of the fish is then shaved open, the internal organs are removed, the gills and scales are removed, and after washing, it can be used for cooking.

Hairtail fish are pelagic deep-water fish and cannot be farmed. Therefore, fishing boats are fishing in the open sea. Deep-sea fish like this are unable to live in the shallow depths of the sea due to their different adaptations to stress, so they cannot survive in the tanks of fishing boats, and they die soon after they are caught.

It takes a long time for fishing boats to return to their seas, so they have to be frozen to keep them fresh.

Why does the hairtail fish expose itself? In fact, it is an exaggeration to say that it blew itself up, and I used a hairtail fish as an example in my answer before because everyone is more familiar with it, and it and whales do not have a swim bladder.

First of all, you have to know why it blew itself up. The reason is that the fishing net quickly pulls it out of the water from the deeper sea area when fishing, and the internal pressure cannot keep up with the external pressure. And then, bang. In other words, if you float slowly, you can go to shallow water.

The principle of self-detonation is similar to that of human diving disease, the gas in the body fluids quickly turns into bubbles due to the change in air pressure, and the main effect is gas embolism, which will burst some small blood vessels in serious cases. For example, the gills will be broken. It's trivial to blow up internal injuries and bleed, some can be disemboweled, maybe there is gas in the digestive tract, I don't know very well.

However, the power is definitely not so powerful that it explodes into a cloud of fireworks. So of course it's complete, ** is an exaggeration, but it's actually an internal injury.

As an aside, in fact, many products in the fishery can be caught alive, such as hairtail, you slowly float up, and the water can be alive. However, it is not necessary. Being alive often means lower efficiency and higher costs.

Therefore, there is no live hairtail, and self-explosion is the direct cause, but the fundamental reason is that there is no need for live hairtail.

01 Because the hairtail is a deep-sea fish, after it is caught, due to the sudden change in water pressure, the swim bladder bursts, so the hairtail fish dies as soon as it comes out of the water.

Hairtail is a deep-sea fish, so what are the characteristics of hairtail? What does it usually eat? Why do ribbon fish die as soon as they come out of the water, instead of jumping around like other fish? Let's answer these questions one by one.

What are the characteristics of hairtail?

Hairtail is a ferocious carnivorous fish, also known as swordfish. They are flattened like a ribbon and silvery-gray in color, with dorsal and pectoral fins light gray. The tail is elongated, like a thin whip.

The dorsal fin of the ribbon fish is long, the pectoral fin is small, the scales are degenerate, and its swimming is not done by the movement of the body like other fishes, which rely on fins. They move freely, not only forward, but also up and down.

Hairtail is a non-picky fish and feeds mainly on hairy shrimp, squid and other fish. They are gluttonous and sometimes kill each other. When fishermen catch hairtails, it is common to see that the tail of this hairtail is bitten by another hairtail, sometimes one bites, and a large string is mentioned.

It is said that due to the nature of the hairtail fish to kill each other and the large-scale fishing of humans, it is rare for them to live to the age of 4, and even less to the age of 8.

How many meters does the hairtail fish live on the bottom of the sea.

As deep-sea fish, hairtail fish usually live 60-100 meters underwater. There are also differences between different species of hairtail, and there is a deep-sea hairtail that lives in trenches at depths of 1,000 meters all year round.

The difference between hairtail farmed and wild.

As far as the hairtail fish is concerned, there is no farmed hairtail fish, all of which are deep-sea wild, the main reason is that there is no way to give the hairtail water pressure to the hairtail, and the hairtail fish is a deep-sea fish, so it cannot be raised, although there is a precedent for the survival of artificially cultivated hairtail fish, but the cost is too high, and there is no way to appear on the market.

Why are all hairtail fish dead?

Because the hairtail is a deep-sea fish, after being salvaged, due to the sudden change in water pressure, the swim bladder bursts, so the hairtail fish dies as soon as it comes out of the water.

The practice of taking fish.

When many families eat hairtail, they usually wrap it in flour and eggs for dry frying, but in fact, there are many ways to eat hairtail, such as: braised hairtail, sweet and sour, chopped pepper and so on. Let's take a look at what you can do with hairtail.

There are pan-fried hairtail, soy pepper hairtail, braised hairtail, chopped pepper hairtail, sweet and sour hairtail, bitter chrysanthemum honey sauce hairtail, steamed hairtail, Lao Gan Ma roasted hairtail, five-spiced hairtail, garlic hairtail, scallion baked hairtail and so on.
