Why do fishmongers add diesel to their water?

In fact, there have been reports about "diesel fish" in many parts of the country, and some friends may think that this fish is caused by environmental pollution, which is actually a wrong view. After all, the number of diesel fish is very large, even if there are hundreds or thousands of provinces, cities and counties in the country, it is impossible to have such a phenomenon as diesel fish in every place. So how exactly did diesel fish come about?

1.Adding diesel fuel is mainly to keep the fish alive

In fact, if you look closely at the diesel fish, you will find that most of these fish are half-dead, and the traders add them to the water.

Diesel is designed to make these fish more energetic.

As we all know, the density of diesel fuel is smaller than that of water, and if the diesel oil is dripped into the basin where the fish is sold, it will float on the surface of the water and form a layer of insoluble oxygen-induced oil film. The fish in the basin were dying, but the lack of oxygen in the water forced them to struggle and jump out of the water to absorb enough oxygen to survive longer.

At the same time, in the eyes of outsiders, this "energetic" live fish must be physical.

The better it is, the easier it is to sell.

2.What exactly are the dangers of diesel fish?

As we all know, diesel is definitely inedible, so the fish that drink diesel will naturally not be able to eat anymore, otherwise it will easily lead to some problems in the body.

Among them, the most harmful is benzopyrene, an organic substance in diesel.

As well as a variety of heavy metal substances that are highly polluting, people will cause harmful substances to react in the body after eating these diesel fish, and then cause chest tightness.

Vomiting and diarrhea and other symptoms, which in turn seriously threaten our health.

At the same time, our human body excretes heavy metals relatively slowly, and once we eat too much diesel fish, it may also lead to our heavy metal poisoning.

3.How can you tell the difference between diesel fish?

Diesel fish is actually very simple to distinguish, from **, whether the fish smells good or not, and whether it is a mobile vendor.

Because diesel fish is a fish that is about to die, it will be cheaper than normal fresh fish on the market by one or two yuan; If you find that the fish is sold at a price lower than the market price, then you must be vigilant.

The second is to smell the smell and look at the surface, there will be an obvious diesel smell around the stall of diesel fish, and the body of the fish is relatively smooth, and it feels like a hand of oil, this kind of fish must not be bought.

Finally, don't buy ingredients from itinerant vendors, most of them do a one-shot deal, and as soon as something is sold, they will run away. By the time you find that there is a problem with the ingredients and want to find after-sales service, they will have long since disappeared. For the sake of everyone's health, it is recommended that everyone go to the regular vegetable market.

Or the supermarket to purchase ingredients, although ** will be more expensive, but eat at ease and rest assured.

In general, diesel fish is still relatively easy to distinguish, but diesel fish has been thoroughly ** by TV stations due to the routine, and this practice of adding diesel fuel to the water is becoming less and less. As long as you are a little careful when purchasing, you will generally not buy diesel fish.

Why do some small fishmongers fill their water with diesel?

In fact, few fishmongers will add diesel fuel to the water, if the diesel is injected, the fish will die quickly, and the ** of the dead fish is naturally very low, which is not what the fishmonger wants to see, in fact, this statement is just a rumor.

Diesel can isolate oxygen, so that the fish can breathe less, the fish will eat less, you can save some money, and the meat will not be firewood.

Because adding diesel fuel can make the dying fish fresh, the fishmonger can increase their profits, after adding diesel to the water, the air in the water becomes thinner, and the fish will keep drinking water and exhaling bubbles in order to get more air, so that the fish looks alive and jumping, like fresh fish.

Some unscrupulous businesses, in order to make the dying fish continue to act as fresh fish**, add diesel fuel to the water to make the appearance of the fish look fresher.

Diesel is less dense than water, so it can float on the surface, which causes the air in the water to become thinner, making the fish more active (in order to survive, the fish in the pond have to swim hard to look more alive), and they drink and foam faster to get more oxygen."

It is said that the fish are poured before the fish are dying, in order to increase the intensity of the fish contention and give customers the illusion that the fish is active. In more than a decade, I have bought this fish twice (once with silver carp and once with bream). The taste is not obvious before cooking, and it is difficult to swallow when you eat it.

The lesson tells me not to buy the kind of fish that is struggling in the shallow water on the beach at any time).

As we all know, the density of diesel is generally, and the density of water is 1kg dm, that is to say, the density of diesel is lower than the density of water, so that there will be a phenomenon that diesel with low density will float on the surface of the water, resulting in the thinning of water and air, and the fish will be very active in the absence of oxygen, and this activity is only a temporary surface phenomenon. If the fish is left in this environment for a long time, in this active process, the fish will absorb a lot of water, which will invisibly increase the weight of the fish itself.

Therefore, adding diesel fuel has become a means of "increasing income", it is already the twentieth day of the lunar month, and there are still 10 days to enter the lunar month. For rural people, entering the wax moon is the countdown to the New Year. Brothers and sisters who are working outside the home will rush home one after another, and the family members will also start to prepare rice, noodles and meat oil for the Chinese New Year.

After all, the Spring Festival is the most important festival for rural people and is highly valued. When preparing New Year's goods in rural areas, many people often see stalls selling live fish at rural gatherings.

When buying fish at these stalls, everyone basically buys one type of fish. This fish smells like diesel. I believe that many friends are familiar with this situation, so why does good fish smell of diesel?

In fact, to be honest, the fish eaten at home in the past were all caught in the wild pond or harvested in the fish pond in the New Year's Village, and they were all fresh. Now, the fish is bought on the street, and it is still alive when it is bought. When it is cooked and eaten, it has a smell of engine oil and the taste becomes very poor.

Basically, I bought it twice and it smelled of diesel. They also said that the fish were specially dragged back from the field and were fresh. To save money, fishmongers may use diesel engines to drive aerators.

When the density of fish is high, the aerator needs to work continuously. After a long time, the air pumped up will take away some of the diesel smell, and then it may be inhaled by the fish. After a long time, the smell of diesel is difficult to dissipate, and naturally there is the smell of diesel.

Because fish is a food, the demand of the public is relatively large, and they will buy it every once in a while.

Because diesel can increase the freshness of the fish, but the density of diesel fuel is less than that of water, if you add water from it later, it will float on the water, which will cause the air to be thinner, in fact, it will become very active in the absence of oxygen, so that customers will think that the fish is fresher and more lively.

Mainly to increase the freshness of the fish, diesel can play a role in oxygen supply, which can ensure the state of the water flow. The main thing is to ensure the freshness of the fish, and the fish can be sold to **.

This can make the fish more fresh, and at the same time, in order to make better use of the oxygen supply machine, it can save electricity.

No, I don't know at all, it's terrifying.

On the news, there is a gentleman from Zhejiang. Bought a silver carp at the market. It cost 50 yuan for more than 8 catties.

He went home and stewed the fish with tofu. I didn't expect to eat a strong smell of diesel. I took a bite and threw it all away.

This diesel fuel can be felt in terms of taste. The gentleman was very angry and went to the vendorThe vendor argued. If you don't add diesel, the fish will die quickly.

Fish that are dying with diesel fuel will be alive. In fact, it is because diesel fuel is denser than water. If you add diesel fuel and float on the water.

There is even less oxygen underwater. Then the fish will jump to the death in order to breathe oxygen. It's not about how fresh the fish is.

Consumers must keep their eyes peeled before buying fish. Don't be fooled anymore.

When buying, you should smell the smell first, and do not buy when you find that there is a peculiar smell such as diesel, and the fish swimming in the water of diesel fuel is shining with oil, because the oil is insoluble in water, and the fine oil beads are attached to the fish scales, and the brightness is relatively obvious.

When buying fish, you should tentatively ask the merchant whether to put diesel into the fish, and then see the seller's reaction.

This is not necessarily what you said, 1, it is said that the fish will jump randomly if you put diesel oil, and the fish that have been jumping are not easy to die (tell a scientific truth: there is a person who transports some kind of live fish for a long distance, and a lot of deaths after a few days, they think of a way, put a few natural enemies of this fish in each tank, and the fish will keep escaping, and the result is that the fish die very little ---this matter is true) So put diesel, I just heard on the Internet, and it has not been confirmed.

2, the second is during transportation, or when using an oxygenator, unintentionally drip into diesel 3, growing in polluted water.

I once bought one, it was live, 3 pounds of silver carp, after cooking, it smelled of diesel, the whole body smelled, the nose could not smell it, only it could be eaten, and it was thrown away.

Typing is so tiring, add points!
