Hairtail is a fish that lives in the deep sea. The deeper the water, the greater the pressure, so the pressure in hairtail is equivalent to that in the deep sea.
When hairtail is caught by us, because the pressure in the outside air is much smaller than that in the hairtail, when the net is off the water surface, it can't bear this pressure at once, causing fatal injuries inside the fish, such as the sudden expansion of the swim bladder, which leads to rupture and rapid death.
Question 2: Where can I buy live hairtail? The hairtail we usually see is frozen hard and lying on the ice. Why can't we see the live hairtail? Just because hairtail lives in the deep sea, the body of hairtail bears huge ocean pressure in this water area. In order not to be crushed to death, the body of hairtail will also release huge pressure outward. When fishermen catch hairtail from the beach, the water pressure in the shallow sea is low, but the internal pressure of hairtail is still very high. The pressure in the swim bladder will burst the swim bladder, and then the blood vessels of hairtail will rupture, so most hairtail will die before landing. This characteristic also determines that it is impossible to cultivate hairtail artificially.
Question 3: Who has eaten live hairtail? . As a person who lives by the East China Sea, I can tell you clearly that there are live hairtail. The smaller hairtail only lives about 50 meters underwater, and occasionally comes to Shanghai for air. At this time, it can be caught alive, but it can't be kept for a long time.
Eat it raw and not silly, but cook it on the boat. It's very sweet.
Question 4: Why can't I buy live hairtail? In the deep sea, due to the great pressure generated by the gravity of seawater, hairtail must ensure the integrity of its body in order to survive there, that is, it will not be crushed to death by such a great pressure, so its body also has a great pressure to compete with the external liquid pressure to ensure its normal body. When people fished it up with a net, the pressure in the body was still very high, and the external pressure decreased sharply, which caused its body to be damaged and died soon, so it was impossible to see live hairtail in the market.
Question 5: Hairtail lives in the deep sea. Have you ever seen live hairtail? Why? The deeper the water, the greater the pressure, so the pressure in the hairtail is different from that in the deep sea.
When hairtail is caught by us, because the pressure of the outside air is much smaller than that in the hairtail, hairtail usually dies because of abdominal rupture.
Question 6: Hairtail is a kind of deep-sea fish that lives at a water depth of about 60 meters, but you haven't seen live hairtail in the market. The water pressure at the depth of 60 meters is about: p = rhogh =1000×10× 60 = 6×10.5pa, and hairtail is in this pressure environment. When the fish is caught, because the external pressure decreases, the pressure in the body is far greater than the external pressure, and it dies under the action of a large pressure difference.
Question 7: Why are there no live hairtail for sale in the market? Hairtail's life habit is that hairtail is a deep-sea fish. It lives on the seabed, and the pressure on the seabed is very high. After the hairtail is salvaged, the pressure is relatively small, and the body cells swell and rupture.
Question 8: Why are there no live hairtail for sale in the market? When the hairtail is caught, it dies immediately because of the huge pressure change.
Question 9: Why are there no live hairtail for sale in the market? These are two encyclopedias. Look, why are all frozen hairtail in the market? 1. Fresh hairtail is silvery gray and shiny; However, some hairtail sticks a yellow substance on the silvery luster. This is because hairtail is a kind of fish with high fat. When it is not well kept, the fat on the surface of the fish is oxidized rapidly due to a large amount of air, and the product of oxidation is to make the surface of the fish yellow.
2. When buying hairtail, try not to buy hairtail with yellow color. If you buy hairtail, you should eat it in time, otherwise the fish will rot and stink quickly.
That is to say, it is still alive, but it is very difficult to keep, and it will soon deteriorate. Why not send it by air?
Question 10: Are there any live hairtail for sale in the market? No, because hairtail needs to live in a high water pressure environment. When the hairtail is salvaged, it is already dead due to the change of pressure. So there is no live hairtail for sale in the market. ..
