Hairy crab is a kind of food that everyone likes very much, this time of year is the time when a large number of hairy crabs are listed, and with the more and more abundant sales channels, people can buy more conveniently, you can choose the vegetable market exquisite selection, you can also buy from the Internet, but in this case, there are still some sales routines or traps, so as a consumer, how to avoid consumption traps when buying?

First of all, in the past consumption traps, crab version of the god and other issues are one of the major problems, there are some businesses in the operation of crabs, the weight of the crab reached 22%, more than 5% of the reasonable range, if this is the case, then, in the vegetable market, there will generally be a special supervision department, and at this time, you can go to the special supervision department to complain and report, if it is determined that it is the responsibility of the business, then the relevant departments will also punish itAs a consumer, when buying these crabs, you must figure out the rope problems of these crabs, because these ropes for tying crabs may be one of the means for merchants to lack catties and short catties.

Secondly, with the development of the Internet, there are many people who choose to buy crab cards and other ways, because if you buy these monthly cards, you can use them at any time, not that you must use them if you buy them now, but there are some crab cards with high standards and low sales, and the exchange information is not clear, that is to say, when consumers buy these crab cards, but there is a difficult problem for the other party, they cannot be used normally, and the crabs exchanged for these crab cards are also very worrying, and according to the merchant, These crabs can only be guaranteed to be alive when they are shipped, and they cannot guarantee that the crabs will be alive when they arrive at their destination, so if this is the case, it is best to choose to buy offline, and some merchants find that he ran away after selling the card, so this has become a difficult problem to pick up the goods.

Finally, when everyone buys crab cards, in fact, they are driven by some interests, and some merchants in order to attract customers with very low **** crab cards, but due to cost pressure, they can not deliver goods normally, so when buying crab cards, we must recognize the strength of the other party, otherwise there may be a ** road.

Crab card crab coupon information labeling and publicity should be seen clearly Crab card crab coupon is often marked by merchants as "666 type, 1888 type" because of its holiday gift attributes, etc., which is easy to make consumers misunderstand its true value, and consumers should pay attention to screening.

It was probably bought in the evening, because it was all leftovers, but I think the quality is pretty good.

I don't think freedom can be achieved yet, even after the price is reduced by 30%, it is very expensive, and a box of ** can reach between 200 yuan and 300 yuan.

Barracuda crabs have a very high reputation in the society, mainly because the ** is relatively high, and many people basically can't afford to eat pike crabs. When 80% of families eat this food, they basically eat it every once in a while, and they don't eat it often, mainly because it's too expensive.

15 catties of ** is about 300 yuan, from the current market ** can be seen, the US dollar ** is about 20 yuan ** is about 25% higher than pork **, although it is not too expensive, but the amount of some pike crabs is really small. Moreover, this is just a wholesale price, and the ** in the market is higher, so many ordinary people basically will not buy it. <>

Many families are only able to eat once in two or three months. Many families are actually able to eat this food only once every two or three months, and this kind of food has a reputation as a luxury in society. Barracuda crab is actually not too expensive for those rich people, but it is indeed relatively expensive for ordinary people, just like pork ** when it is about 30 yuan a catty, the demand in the market is relatively small.

Sales in the north are relatively small. This kind of commodity is relatively luxurious, for many places in the north, in fact, there is no habit of eating this food, and many people in the north also think that seafood does not match his taste. Generally speaking, people in the south prefer to eat this food, and the sales in the south are relatively high, and the sales in the north are relatively low.

In fact, every place has the habits of every place, and the reason why there will be a decrease in the first place this year is because this year's output is relatively high, and the demand in society has not increased. Under the influence of supply and demand, the ** of pike crabs will decline, which is indeed good news for people in the south.

Of course this is not the case, because this year's pike crab ** is indeed more dropped, but if you want to achieve these freedoms, it is still more difficult, and it is still acceptable to eat once in a while.

Although the pike crab is much cheaper, it is still very expensive for ordinary families, and it is impossible for us to achieve the freedom to eat crabs.

It should be possible, but it is still difficult for people in inland areas to achieve, because it is still very expensive to transport it.

Usually 30 a catty, the price increases by 50% on Sunday

The aquaculture yield is about 200 kg. And now the market production is relatively small, and there are also **, sales are relatively tight.

Most of the output of artificial breeding is not very much, and it is generally only tens of thousands, after all, in the process of breeding, you need to understand this technology, and you must know some of the most basic content when breeding.

The artificial breeding output of pike crabs is about more than 10,000 catties per mu, and the profits are very considerable.

The ** of hairy crabs dropped by half directly after the festival, for example, the price of a two-two line was 25 yuan before, and it only cost 12 yuan to buy it later. The ** diving of ordinary crabs is more serious, and the price of high-quality products continues to rise. From the above situation, it can be seen that there are some things that can only be sold at a certain time, and then the ** will fall back slightly.

However, the decline of crabs has made its sales more popular, because people still like to eat crabs, but they didn't dare to buy them because of ** before, and now they can eat them separately.

In fact, there is an invisible means to control the development of the market, if you feel that the ** of a certain product is particularly high, you should understand that you are now in a seller's market. For example, during the holidays, many people want to give gifts, or buy a gift to take home, which will make the ** of these gifts rise sharply in a short period of time. And after the festival, people's lives will return to normal and will live a budget-conscious life.

At this time, the ** of crabs must decline, otherwise they will not be able to sell and crab farmers will not be able to get benefits.

Some market operators have shown that because the best is very affordable, the number of people has risen sharply, and basically more than 100 can be sold every day. Although it is said that ** is less than before, for example, the price of one is only 12 yuan, but more than 100 are also more than 1,000 yuan. In fact, the hairy crab itself does not have much meat, but the crab roe in it is very delicious, and the thread should also be eaten in season, so that you can feel the sweetness.

Consumers will also focus on cost performance when making purchases, and they will buy two or two local hairy crabs, and the sales of these two crabs are even more impressive.

When eating crabs, you can buy fresh ones, which will be healthier, and you can also steam them directly, which can retain the original umami taste of hairy crabs.

Yes; It will definitely have a great impact on the market, because such a ** will definitely lead to consumers making different choices, so the sales volume will definitely be different, affecting the overall pattern of the market.

This will lead to a polarization in the market, with some hairy crabs continuing to rise, while ordinary hairy crabs are facing significant price reductions.

In the future, hairy crab breeding will continue to be polarized, and farmers who blindly pursue quantity and do not pay attention to high-quality products may be eliminated.

In the Yuegezhuang seafood wholesale market to investigate whether the stall selling crabs has the phenomenon of dead and alive, the reporter bought three pike crabs on the spot, but the merchant said when bagging: "Don't look for me when you go home and find that you are dead, this water is easy to die." The reporter immediately asked to see if the crab was alive or dead, but the merchant said:

There are too many things to sell. Some experts said that merchants have been selling crabs for many years, and their methods are old-fashioned, and they have special methods to deceive consumers.

At the Yuegezhuang Seafood Wholesale Market, an unannounced visit was made to investigate whether the stalls selling crabs were dead or alive. The reporter bought 3 pike crabs, and after the merchant put them in the bag, he suddenly said: "Don't look for me when you go home and find that you are dead, this one is easy to die when it comes out of the water."

The reporter immediately asked to see if the crab was alive or dead, but the merchant said:There are too many things to sell.

Dead crabs in the seafood market become live crabs, dead crabs become live crabs, Yuegezhuang seafood wholesale market, Yuegezhuang dead crabs become live crabs, that is, merchants can earn a profit of yuan by filling life with death in this way. The reporter also remembered that when buying crabs, the merchant's method of taking crabs was very similar to the previous method of filling crabs with dead and alive. In this regard, the reporter asked experts, and experts said that when many merchants took out the crabs, the crab's legs only looked like they were moving, but in fact, the vendors were moving the crab's legs with their hands.

Mainly because a little substance is added to the water to make it look moving.

It is by adding a liquid to the seafood so that their limbs react.

It must have been added to the water with some bad substances, so that the crab could move, although it was no longer alive.

It's just the use of some chemicals to give the dead crab some characteristics of a living body.

It is believed that some chemicals were used to catalyze crab activity.

They just add some additives to the dead crab, which looks like a live crab, but it will actually be more harmful to eat.

Pay attention to the merchant's index finger and little finger. It turned out to be the merchant's fingers, not the crab's legs at all.

The merchant may have added something unknown to the crab, so the crab came to life.
