Why is there no live hairtail?

Question 1: I want to ask why there are no live hairtail in the market. Because hairtail lives 50-80 meters underwater, it belongs to carnivorous fish. She eats the same kind. Because the water pressure in the place where he lived was very high, the water pressure on it was not enough, so he died as soon as he was salvaged. He can't be educated. Hairtail now lives in the East China Sea and South China Sea of China. Artificial culture is difficult. If possible, it will cost a lot of money. No need to cultivate.

Question 2: Hairtail lives in the deep sea. Why can't live hairtail be seen in the fish market? Because of the high water pressure in the deep sea, hairtail is flat. After the hairtail is salvaged, the pressure in its body is enough to crush it, just like people will not adapt after diving.

Question 3: Why are there no live hairtail and yellow croaker on the market? Yellow croaker and hairtail are fish that live in deep sea. They can withstand much greater pressure than in our air. When they are fished out of the sea, due to the sudden drop of external pressure, a series of changes have taken place in the fish, which makes its volume expand and burst. In addition, in the blood of these fish, the oxygen originally absorbed by blood cells also presents a special "boiling" state due to the decrease of external pressure. Therefore, deep-water fish such as yellow croaker and hairtail died as soon as they were taken out of the sea. So what we see is iced!

Question 4: Why are there no live hairtail on the market? I've never seen anything alive. Look at it. When hairtail was caught, it died immediately because of the great pressure change.

Question 5: Why did live hairtail (non-ornamental) not sell on Taobao, but died after being caught from the sea? There has never been a live hairtail.

Question 6: Why didn't the hairtail you saw live? Hairtail lives in the deep sea and is used to the pressure in the water. Suddenly lost pressure and died when he was caught. Deep-sea fish basically die out of water, such as yellow croaker and pomfret.

And if people dive into the deep sea and suddenly come up, they will die.
