Why do rural elders say that blue crabs can t be bought with a particularly large size?

Because it is very large, the attack power is high, the defense is ridiculously invulnerable, the crab claws can easily trap people to death, but it is difficult for people to deal with the big blue crab.

A: Because the particularly large blue crab may have been manually operated, for example, hormones. This is harmful to our health, so we should not be greedy for cheap, the consequences are still more serious.

This is a rural superstition, and the old people in the countryside will think that the big blue crab is a blessed thing and should not eat it, so they are not allowed to buy particularly large blue crabs.

Because some people think that the blue crab that is too big is the old blue crab, it may be the previous year, and the taste is not so good.

Because the big blue crab ** is very expensive, the old man said that the blue crab should not be bought particularly large.

Personally, I think it's because the big ones aren't delicious, and the nutritional value of the big ones isn't as good as the small ones, in short, the big ones aren't good.

I think it should be a relatively large blue crab, and it is also more expensive, so there is this saying, which means that it is cheaper to buy.

Blue crab. Generally, the bigger the better, and the more interesting it will be, and the smaller the blue crab generally does not produce butter crab.

This kind of blue crab will also be relatively cost-effective. It depends on the size of the blue crab to buy green vegetables and radishes, if you like to buy big, you can choose big, and if you like to buy small, you can buy small, and everyone's hobbies are all different. For example, blue crabs and pike crabs.

I like to eat relatively cheap pike crabs, and the taste of pike crabs will be more delicate. Blue crab is expensive in fact, it is expensive, blue crab will generally be given as a gift crab, because blue crab has a good effect of nourishing and nourishing the human body.

However, the total number of natural blue crabs is now getting lower and lower, so there is no doubt that blue crabs in the wild are more expensive, and artificially bred blue crabs will be relatively cheaper. The nutritional value of blue crab is relatively rich, and the meat texture is particularly delicious, according to the type of blue crab that does not agree, the size has long been the difference between the blue crab, ** is very far apart, it is very likely that the same kind of blue crab, ** will be dozens of times apart. The key reason is because the vast majority of today's artificially bred blue crabs, natural too little, generally the more blue crabs, the higher the proportion of its shell to body weight, and the more blue crabs, the people who sell blue crabs will use thicker ropes to tie, so the net weight is likely to be more loss.

The ** of blue crabs, the blue crabs sold in the normal sales market, generally how much, are about 60-110 yuan per catty, and if these are larger blue crabs, then ** will need to be around 150-200 yuan per catty. Unless you are a rich person, you can buy as many blue crabs as you can eat, after all, even if it is a small blue crab, it tastes very delicious, it is crab fillet.

It's a little less, but the nutrients are the same.

The taste of blue crabs, normally speaking, how many blue crabs are generally there, everyone in the case of eating, the taste should be fresher, and the crab shell is relatively thinner, so it is more convenient to eat it, just like me, sometimes in the case of eating that kind of small blue crab, it is mostly to immediately dip the small crab legs in some condiments, and then you can directly put it in the mouth to chew and the big blue crab Everyone will feel a little more fragrant when eating it, and the crab fillet also needs a little more, but relatively speaking, everyone is in the case of making a big blue crab, It also takes a little longer, and it is slightly inconvenient to eat, after all, the crab shell of the big blue crab has to be peeled off.

It has something to do with **, it has something to do with taste, and now most of them are artificially farmed, so there is such a saying.

Because most of the blue crabs are actually artificially farmed, the larger the size, the higher the weight of the shell, which is relatively not cost-effective.

Because the elderly in rural areas think that blue crabs generally get bigger the older they get, but the older the crabs, the more unpalatable they are.

Do you have a fish tank, it is better to raise it in a fish tank, if not, you can use a basin to raise it, the water is shallow, otherwise it will drown. However, it is better to have water freshly soaked in the shell.

You can put it directly in the basin, and the basin must have a certain height, otherwise it will climb out, or don't put water, it will be easy to lose weight. And now that the weather is cold, I have to find something to cover the basin at night, this thing is afraid of cold.

However, in order to have a more delicious taste, it is best to eat it first and buy it when you need it.

Crabs are omnivorous.

You can feed them fish, whether it's raw or dried. They may also be fed fish feed, bloodworms, dried shrimp, snails, mussels.

It is best to feed some grass-based foods frequently, such as bitter grass, eloso, etc.

As long as the feeding is OK, there is no need to worry about the rest, the crabs are very easy to raise.

Blue crabs are not big gates.

E68a84e8a2ad62616964757a686964616f31333366303733 crab, are two varieties of crabs. Blue crabs belong to the category of sea crabs, and hairy crabs belong to freshwater crabs.

The difference between blue crab hairy crab.

1. The dorsal carapace of the blue crab is horizontally oval and the sides are sharp. The nail surface is smooth, the forehead has four teeth of equal size, the anterior lateral margin contains the external teeth of the eye socket with a total of 9 large teeth, and the fourth step foot is flattened and specialized into a paddle-like swimming foot, which is suitable for swimming. chelicerae smooth, asymmetrical, right foot slightly larger than left; The metacarpal segment is swollen and smooth, with 2 granular ridges on the dorsal surface, each with 1 spinous at the end.

The first three pairs of feet are toothless, and the anterior and posterior edges of the knuckles have short brush-like hairs.

2. The cuirass of the hairy crab's head is round and square, and the back half is wider than the front half. The dorsal area is raised, the frontal and liver area is depressed, and the front of the stomach area has 6 symmetrical protrusions, each with granules. The gastric area is sharply demarcated from the heart, and there are pitts around the former.

The forehead is broad, divided into four teeth. The upper edge of the eye socket protrudes near the middle and is triangular. anterior margin with four acute teeth, the last one the smallest, and introduces a ridge line, obliquely running on the lateral side of the gill region; There is also a bulge along the inner side of the posterior margin.

Chelicera, male and female, densely villous on the inside and outside of the base of the metacarpal and phalangeal segments, with a sharp spine at the inner terminal corner of the carpal segment, and a sharp spine at the proximal end of the dorsal edge of the long segment and the long segment of the foot. The last three pairs are relatively flattened, with bristles on the dorsal and anterior margins of the carpal and anterior segments, and bristles on the dorsal and ventral margins of the anterior segments and the base of the knuckles in the fourth step. Abdomen, male round and male pointed.

The cephalothorax was 54 6 mm long and 61 0 mm wide.

Of course not. Blue crab: The scientific name is saw-edge blue crab. The male is called a meat crab, and the female is called a cream crab. It's a sea crab. The scientific name of hairy crab is Chinese mitten crab, which is a river crab and a lake crab. It is smaller than a blue crab and has golden fur on its claws.

The difference between blue crabs and hairy crabs is that blue crabs are in the sea, while hairy crabs are in rivers.

The reason why blue crabs are expensive is because of the high transportation cost of blue crabs, the difficulty of breeding, and the high nutritional value. Blue crab is generally produced in coastal cities, to transport it to inland cities for sale, the transportation of material and manpower is relatively large, and in the transportation, blue crabs are likely to die part, so it will be relatively high after entering the inland area.

Why are blue crabs so expensive

Blue crab is rich in protein, amino acids, vitamins, calcium, phosphorus, iron, potassium and other trace elements.

As burrowing aquatic crustaceans, blue crabs prefer to inhabit muddy beaches, mangroves or marshes in the intertidal zone.

Blue crabs mainly use small fish, shrimp, crabs, shellfish, etc. as bait, and are widely distributed in the Pacific Ocean and Indian Ocean.

An old farmer who has been raising crabs for 20 years told me that if you eat crabs in October in the countryside, you better buy female crabs to eat. Because before October in the agricultural calendar, the yellow of this female crab is the fullest, and the taste is the most fragrant. At this time, the male crab has relatively little crab white gelatin, and it is not so good in taste.

So during the Mid-Autumn Festival, if you want to eat crabs more deliciously, it is best to buy female crabs.

The picture above is the blue crab I bought in the vegetable market recently, although this blue crab is only 3 taels of town Tong attack, but there are a lot of crab roe in it! See if it makes you hungry?

If you want to buy crabs to eat after the tenth month of the lunar calendar, you have to choose male crabs to eat, because at this time, male crabs have more gelatinous texture and become extra fat, which is the best time to eat! At this time, the female crab has less meat because she has given birth, and it is the time when the taste is the worst.
