Here's how to tell the male and female of a crab:

Natural enemies of crabs

1. Crab-eating fox: living in South America, the main food is crab meat, and occasionally eats some fruits, birds, insects, lizards, etc.

2. Goby: It is a carnivorous fish, which will live near shallows, reefs or corals filled with seawater, and some live in freshwater lakes or swamps, and these places are also the main habitats of crabs.

3. Squid: Although it is a mollusk, the wrists and feet of the squid are very powerful, and they can even break the shell, but most of the squid choose to use the beak mouth to bite the crab shell directly and eat.

4. Plover: It is a kind of water bird, living near the beach all year round, and its favorite is some small fish and shrimp, especially the crab is the favorite of the sand plover, as the natural enemy of the crab, it will pick up the crab and throw it out violently, until the shell of the crab is broken into pieces, and then use the sharp mouth shell to eat.

In the blink of an eye, it is the season to eat crabs, and the pike crabs we have here have begun to be listed in large quantities, the disparity is relatively large, ranging from more than ten yuan to fifty or sixty yuan a**, some people will feel that their different sizes have caused their ** differences, in fact, there are differences in crab sex and fatness, so how should we distinguish male crabs, female crabs and fin crabs when we choose pike crabs? What season is the fattest crab? What to do to make it the most delicious?

The sex of the pike crab.

Many people know that crabs are divided into male and female, but they don't know that there is a third gender of pike crabs, that is, fin crabs, fin crabs are female crabs that have not gone through mating, and after mating, fin crabs can be called female crabs, in this way, everyone should know it, so how do we distinguish male crabs from female crabs and fin crabs? Don't worry, let's move on.

Male crab: The navel of male crab is long, the individual is relatively large, and the meat is very firm, so it tastes the most delicious.

Female crab: The navel of the female crab is relatively large, and it is very round, and there will be patterns, but the female crab in the qualified season has just produced crab roe, and the meat is not fatty, and after the Mid-Autumn Festival in August, it will become fat and have crab roe.

Fin Crab: The navel of the fin crab is triangular and relatively small, but the taste is the fattest in this season.

In this way, we can distinguish their fatness, the crab has just been listed, the female crab has not yet crab roe, it is relatively thin, the male crab is very delicious, and the fin crab is the fattest, don't look at its size, but the meat quality will definitely bring you a lot of surprises. Crab is a kind of seafood, of course, to eat seafood, we must pay attention to freshness, steaming this method is the best way to retain the freshness of food, so crabs should be steamed to taste more delicious.

Many people will find such a situation when steaming crabs, that is, the crabs will be heated and struggling in the process of steaming, so that the crab legs will fall off, which will affect the beauty of the crabs, in order to solve this problem, we don't put the live crabs directly into the pot to steam, we must first use a sharp weapon to pass through the crab's mouth, so that the crab will die, and then steam it in the pot, so that the crab will not lose its legs.

Of course, you can also put the crab directly into the refrigerator to freeze for an hour, at this time the crab will not die, will only be frozen and fainted, and will not be heated and struggle to break the leg when steaming in the pot, and it will taste better in this way, here we should pay attention to it, if the crab is tied with a leather band, then we must take it off, if it is a straw rope and cotton thread, it doesn't matter, after all, the leather ring and the crab are steamed together, which will affect the taste of the crab, and it will also produce harmful substances after high temperature, It will have a certain impact on physical health.

This hairy crab is still quite good, ** is also very reasonable, although the male and female are random, but each one will have yellow cream, it tastes very fresh, and it is worth compensation when it dies.

Observed shape: The abdomen of the male crab is triangular, and all eight legs are hairy, while the abdomen of the female crab is round or oval, and only the front two legs have hairs. Observe the crab roe:

Crab roe is peculiar to female crabs and is yellow or orange-yellow in color. Observation of crab paste: Crab paste is the accessory gonads of male crabs and their secretions.

1. Observe the appearance

There is a clear difference between the appearance of male crabs and female crabs, the main difference is in the abdomen and legs, usually the abdomen of male crabs is triangular, and the eight crab legs are all hairy, while the abdomen of female crabs is round or oval, and only the front two crab legs have hairs.

2. Observe the crab roe

Crab roe is unique to female crabs, which is the ovaries and digestive glands of crabs, and the color is yellow or orange-yellow, and the crab roe contains crab eggs that are not excluded by female crabs, which has extremely high nutritional value, and mature female crabs are full of crab roe.

3. Observe the crab paste

The male and female of the crab can also be judged by the crab paste, because the crab paste is the accessory gonads and their secretions of the male crab, which is blue-white translucent jelly-shaped, and after the male crab matures, the accessory gonads are abnormally developed and will lift the crab shell.

Male and female can be distinguished by the belly, legs, roe, paste, etc. of the crab.

The abdomen of male crabs is triangular, and the abdomen of female crabs is round or oval. The male crab has dense hairs on all eight legs, while the female crab only has fine hairs on the front two legs. Because the crab roe is the ovaries and egg cells of the crab, the male crab does not have the crab roe, and the female crab does.

Crab paste is the accessory gonad of crabs, so male crabs only have it, but female crabs don't.

China has a very long history of eating crabs, and the resources of crabs are also abundant. Autumn is the best time to eat crabs, when the crabs are ripe. The question of whether male crabs are delicious or female crabs is delicious varies from person to person, some people like to eat crab roe, and some people like to eat crab paste, or you have to choose according to your own preferences.

Precautions for eating crabs

Do not eat dead crabs, after the crabs die, they will produce a large number of bacteria, which will speed up the deterioration and decay of the crabs, and they cannot be eaten even if they are cooked. These four parts of the crab's gills, intestines, stomach and heart should not be eaten because these parts contain the excrement of the crab, so they cannot be eaten.

Crabs should be cooked thoroughly before they can be eaten, otherwise there will be bacterial residues that make them inedible. Crabs should be steamed and eaten, do not store, even if they can't be eaten, the rest must be kept in a clean, cool and ventilated place, and they must be returned to the pot and steamed again when eating. Do not drink tea when eating crabs and within 1 hour after eating crabs, because boiling water will dilute stomach acid, and tea will cause some components of crabs to coagulate.

There are two ways to distinguish male and female crabs, in fact, from the appearance, it can be very good to distinguish male crabs from female crabs. One is to look at the abdomen and the other is to look at the legs.

1. Distinguish male and female from the abdomen, in most cases, the shell of the abdomen of the male crab is generally pointed, while the shell of the abdomen of the female crab is round, through this method, it can be judged well. In addition, when judging male and female crabs, you can look at the bottom of the lid of its abdomen, the more pointed and narrow ones are male crabs, and the wide and round ones are female crabs.

2. It is also very easy to distinguish from the legs, the female crab only has fluff on the front two legs, and there is a gray-black pile of fluff on the two chelae, but the female is only this hair, and the rest of the legs are smooth. The male crab has fine hairs arranged like a brush on its eight legs. Compared to this method, it is relatively simple.

How to tell if a crab is *** bad.

1. Look at the color: The back of the crab is the best cyan shiny.

2. Look at the weight: not the bigger the crab, the better, when you buy it, you can compare the same big crab which is heavier, and the heavier meat is more.

3. Look at the tail: the tail of the female crab with more crab roe is thicker.

The distinction between male and female crabs is as follows:

1. The listing date is different: female crabs are generally sold before male crabs; Around mid-to-late October, the female crab is basically already round, and the quicksand version of the crab roe is very gluttonous and the best at this time. Until mid-to-late November, it can basically be said that it is the world of male crabs.

At this time, the yellow of the female crab can be regarded as too hard; And the male crab is thick in cream.

2. The abdominal cavity is different: Generally speaking, the abdominal cavity of a giant crab has a crab navel that can be opened, while the abdominal umbilicus of male crabs is triangular and the top is sharp, but the abdominal cavity of female crabs will be smoother because they must reproduce offspring, so they will be more round, round or oval.

3. Crab legs are different: Generally, the eight crab legs of male crabs still have gathered hairs, and the crab legs feel good and look very round, but the crab legs of female crabs only have hairs on the front two legs.

4. The texture of the meat is different: the taste of male crabs is firmer, the taste of female crabs is softer, and only male crabs will have crab roe, and crab roe will only be found by female crabs.

5. The difference in nutritional composition between male crabs and female crabs: for example, the roe of male crabs generally does not contain a little carbohydrate, while the crab roe of female crabs contains carbohydrates. Secondly, male crabs also have female crabs, and its crab roe is also rich in human fat chemicals and its protein also has vitamins, so its nutrients are generally very rich and diverse.

6. The difference between the eating method of male crabs and female crabs: when taking male crabs, the general forest liquid can be taken by exploding male crabs. Clean up the giant crab, and then separate the male crab shell and feet, put it in the middle of the pot for an oil explosion, add a little condiment, and the oil will be fried for ten minutes, and it can be directly out of the pot.

This uproar. For female crabs, it can generally be taken by steaming, and there are a lot of crab roe ingredients in female crabs. Steamed female reed crab can also ensure that it is raw.

Notes:

If you want to see at a glance, it is best to distinguish from the legs, the female crab only has fluff on the front two legs. Male crabs have fluff on all 8 legs.
