On the 26th of this month, at the Wenzhou Xiaojiang Toll Station of the Yongtaiwen Expressway in Zhejiang Province, a driver transporting fish was stopped by the staff, saying that the fresh and not fresh fish he transported were mixed together and did not belong to the fresh agricultural products stipulated by the state, so they had to charge tolls.
The driver was very emotional, holding half a fish in his left hand, saying "None of you said that the fresh fish was fresh, the leader came not fresh, you see..." Later, the driver posted the video to the Internet, saying that he unloaded the ship at noon and loaded the car, and arrived at the toll station at 4 p.m., but was said not to be fresh fish, so angry that he ate half of it, and then he was released for free.
Half a fish stirred up thousands of waves, the video quickly fermented, triggered a hot discussion and likes from netizens, the hottest of which is that "taking the fish out of the water is basically dead", so it cannot be said that the fish is fresh or not alive.
To search the Internet, the most popular saying is that the fish will explode when they come out of the water, because the fish live in the deep sea, bear great pressure underwater, and after reaching the surface of the water, because the atmospheric pressure is much smaller than the water pressure, it will explode itself, and the internal organs will rupture and die. There is also a saying that the fish seen in the market are often broken stomachs, which is self-detonated.
So, does the fish really explode as soon as it comes out of the water? Do fish really die when they come out of the water? The driver unloads the boat at noon and loads the car, and arrives at the toll booth at 4 p.m., is the fish alive?
First bringing a fish out of the water and blowing itself up is definitely an exaggeration. Striped fish are not deep-sea fish, deep-sea fish generally refer to fish living below 200 meters in the water depth, while the living environment of the striped fish is 20 meters to 100 meters deep offshore, and the breeding period will also swim to 15 to 20 meters near the surface layer.
Because the "pressure" of life is too great, once the deep-sea fish is "invited" by humans to come to a place with little "pressure" near the sea surface, the internal organs may be squeezed or squeezed out of the anus or mouth, or the gas in the body fluids will become bubbles, just like human decompression sickness, resulting in embolism or some small blood vessels rupture, and then die quickly.
Since real deep-sea fish will not explode, turning into a pile of flesh and blood blurred fragments, it is really too exaggerated to say that the fish will explode on their own. In fact, the fish caught by fishermen do have intestines and stomachs, but it is not self-detonation, most of them are squeezed and scratched in the fishing nets, and the death of the fish is more because the speed of being brought to the sea is too fast, and the internal organs and blood vessels of the body cannot withstand the pressure changes and rupture and die.
So the answer to the second question also comes, with fish are not all out of the water on the death, in fact, netizens from the shallow sea fishing up the fish not only live jumping, but also very fierce, after all, people are predatory fish in the ocean, so when catching, you must be very careful, otherwise it is easy to be hurt by it.
And the fish that have just been caught are very beautiful, like a silver-blue sword, reflective like a mirror, really, you may never have seen such a beautiful fish, the ancient seaside place where fish are sold, one by one hangs there, and many people think that they are selling weapons from a distance.
But it doesn't last long after taking the fish out of the water, even if you put it in a larger tank, so the best way to keep it fresh is to put it on ice after it comes out of the water. After the fish dies, the beautiful appearance will also disappear, and it will slowly become the white gray we usually see.
The driver said that unloading the ship at noon and loading the car, arriving at the toll booth at four o'clock, four hours, there may indeed be a lot of fish dead, those with broken stomachs, fish heads dropped, it is indeed possible that it is not a mixture of fresh and not fresh, but caused by fishing. How to define it is indeed a test for the staff of the checkpoint. However, since I don't know how the fish in the car are transported, the statement here is only a family statement, so please understand it carefully.
China is a big country in the consumption and fishing of striped fish, in 2009 the world fished 1.3 million tons of striped fish, China accounted for 1.2 million tons, is definitely a nightmare with fish, fortunately, the strip fish seems to be able to really grow and raise, the output has been relatively stable. But there are also people who are worried about the fish in the sea, so it is recommended that artificial breeding, many people may have to sneer, take the fish out of the water to die, it is impossible to artificially breed.
According to news reports, in 2017, the Zhejiang Zhoushan Landscape Research Institute has successfully bred and survived a batch of fish fry in a 1.1-meter-deep pool, growing to 30 or 40 centimeters long, and achieving phased results.
The team's fish-carrying fry came from cages in the sea, about one or two centimeters long, about six or seven hundred. After a period of rearing, it was put into a transfer box and transported to the institute, and after 4 hours of transportation, more than 100 died, and then many died, and about 300 survived in the end. However, how the research is going now, there is no follow-up statement found on the Internet.
But from this incident, we can guess that the driver of Zhejiang who "eats raw" fish may still be alive in the fish transported, so he is very angry: "There are one or two broken and U-turns in a box, and when taking pictures, he is specially broken, and he does not take pictures." "Life is hard enough, let's stop making it difficult for each other."
Therefore, there is really no scientific reason for taking a fish out of the water and exploding itself; even if you take a fish out of the water and die, it depends on how you understand, what fish does not die when it comes out of the water? It can only be said that after taking the fish out of the water, you can't live in the water for a long time like other fish, but you will die quickly. The real cause of its death may need to be studied in more depth.
