What do you think is the difference between a crayfish and a lobster?

Generally speaking, the ** of lobsters is expensive, and they are all hundreds of dollars a catty. The lobster grows in the sea, the lobster has a very high economic value and nutritional value, the lobster contains very little fat and a lot of protein. Crayfish is a kind of freshwater shrimp, and the ** of crayfish is relatively economical, generally at most dozens of yuan a catty.

Sea shrimp is the most easily confused shrimp with lobster. Although the claws of the sea shrimp are very conspicuous, large and wide, like a pair of plate axes, but its size is as huge as the lobster, and the same life in the ocean, so many sea crayfish are simply named lobster in the market**, the most famous is the American sea prawn known as the "Boston lobster", and the lobster, their price is also very high.

Compared with crayfish, Australian lobsters are the real "lobsters", compared with the crayfish we often eat, this kind of marine lobster has its distinctive characteristics: including belonging to the decaptome with 5 pairs of feet and 5 pairs of swimming feet; The blood has no red blood cells and is blue; The shell contains a lot of astaxanthin, which is red when cooked. Although the meat quality of the cooked Australian lobster is also very delicious, and the edible part of the Australian lobster can be dozens of times more than the pitiful tael of meat on the crayfish, but the ** of the Australian lobster is enough to discourage ordinary people.

The term lobster is a collective term for more than a dozen species of marine lobster, while crayfish refers more specifically to the crayfish that has been widely eaten in recent years. Here you should clearly see that the relationship between lobster and crayfish is still very close, but the crayfish where the lobster is located are without big pincers, which is the most intuitive difference between lobster and crayfish. Lobsters in the strict sense of the word do not have claws (large pincers).

Lobsters and crayfish belong to the decapod order with 5 pairs of feet and 5 pairs of swimming feet. Both have blue blood, a large amount of astaxanthin in their shells, and red when cooked. Depending on whether it molts or not:

When crayfish grow to a certain stage, they will molt and become soft-skinned shrimp, which lobsters generally do not. Depending on the living environment, crayfish live in fresh water, whereas lobsters live in seawater.

In fact, no one ate crayfish in China a long time ago, and crayfish could generally be found in ditches and rice fields. However, crayfish eating has since emerged, and its variety of cooking methods and tender meat have attracted a large number of loyal diners, especially female customers. Foreign lobsters are basically dominated by sea shrimp, and they are generally larger.

There are also crayfish similar to those in China, but crayfish are basically not eaten abroad, because they feel that this kind of crayfish may carry germs or other harmful substances to the human body.

Crayfish is a favorite delicacy of many people, and when it comes to crayfish, many people are so hungry that their mouths drool. The lobster we often talk about is not a real lobster in biology, its scientific name is crayfish, also known as red crayfish, and crayfish is its common name. Australian lobster is the real lobster in biology, its scientific name is Australian rock lobster, belongs to the genus of arthropod phylum rock lobster, its size is much larger than that of crayfish, the two put together, the difference looks very big, Australian lobster is fiery red throughout, the claws are golden yellow, the meat is very delicious, and it is also a precious freshwater edible shrimp species.

1. Region.

The biggest difference between lobsters and crayfish is that they are located in different areas. The former is shrimp in the sea, and the latter is shrimp in the river. That is, one is seafood, and the other is river fresh.

2. Appearance. Large lobsters don't have big pincers, which is the most intuitive difference.

Crayfish: Crayfish resemble a shrimp with a hard carapace, the adult body is about centimeters long, dark red, the carapace part is nearly black, and there is a wedge-shaped stripe on the back of the abdomen.

3. How to eat. The main meat of lobster is the waist and tail, so many restaurants sell lobsters only on the lower body. But because the crayfish has a large pincer, the meat of the pincers is very sweet except for the tail accident.

4. Taste. Crayfish have a slightly fishy smell because they grow in freshwater and swamps. So whether you eat it boiled or stir-fried, add some chili peppers or other spices to suppress the fishy smell. And the lobster lives in the sea, which is better.

Crayfish live in freshwater, and large lobsters live in the sea, one is freshwater and the other is saltwater!!

Crayfish has always been known as the crayfish of an invasive alien species. Its ancestors first lived in the Americas, and has a domineering scientific name, but salt shrimp. There are many types of lobsters, rock lobster, splendid lobster, rippled lobster, honey mango lobster, etc., and we also have many types, sweet crayfish, spicy crayfish, beer crayfish, stir-fried crayfish and so on.

The blue-black crayfish is called Lagu, and some people call him spicy bones. Although these two look alike, they are not their teammates, unlike my invasive species, it is an authentic Northeast shrimp, this guy has a habit of cleanliness, I can live in polluted water, chew carrion, gnaw aquatic plants, eat mud, crayfish can't, so the team of crayfish is getting bigger and bigger, and they are all about to be endangered.

Many people think that foreigners don't eat crayfish, but in fact, at the beginning of the 16th century, that is, in 1523, Sweden became independent, just founded, poor, so their boss began to encourage the common people to be a kind of crayfish that can be seen everywhere in their local area, the result is really fragrant, and later they also specially organized a crayfish festival. Later, crayfish began to become popular in Europe, and the United States became the first country to breed crayfish.

In 1927, crayfish were introduced to Japan as feed for bullfrogs, and life was boring and boring, but we did not give up on ourselves, and still continued to work hard to improve ourselves. The Japanese and Korean teams began to grow day by day, and after a few years, the crayfish finally came to Nanjing, China, which didn't seem to be very tasty, but I believe that in such a country with a long history of food, any kind of beautiful ingredients will not be buried forever.

In 1993, the people of Jiangsu had an epiphany, they developed a way to eat thirteen spiced crayfish, and we finally became an instant hit and became the most popular Internet celebrity food in the country. However, as the so-called shrimp red is too much, the sewage of crayfish living is too dirty, the crayfish heavy metals exceed the standard, and the crayfish eat garbage. In fact, it is just better adapted to the environment than ordinary animals in the water, because we contain astaxanthin in our body, and the astaxanthin content is directly proportional to the harshness of the surrounding environment, which can help us enhance our survival ability.

Regarding the problem of heavy metals, the body of crayfish exposed to the heavy metal environment will indeed be enriched with some harmful elements, but most of the heavy metals in their bodies are distributed in the head, that is, the visceral part and the shell, these parts will indeed have the risk of excessive heavy metals, but the heavy metals in the meat are in line with safety standards, so we don't eat the head.

I've eaten both lobster and crayfish. And the difference between lobster and crayfish is as follows:

1. From the point of view of appearance, lobsters do not have large tongs, and crayfish have tongs.

2. Lobsters are more expensive, and crayfish's are more affordable.

3. Lobster has less fat content and contains high-quality protein, which has a very high edible value for the human body. And crayfish, although rich and delicious in taste, is not as good as lobster in terms of edible value.

The difference between crayfish and lobster is mainly size, habitat, color.

The difference between crayfish and lobster is mainly the difference in origin, appearance and so on.

1. The difference in origin.

Crayfish is often said that the kind of red crayfish, the individual is not as big as the lobster, mainly produced in China, now China's Fujian, Guangdong, Guangxi, Jiangxi, Hubei, Anhui, Zhejiang and other places are cultivated, and crayfish like to grow in relatively shallow rivers, and lobsters are relatively large, mainly live in the sea area, now the bureau letter is distributed in Central and South America and Mexico, Zhejiang Zhoushan area is also distributed, the amount of artificial breeding is not much.

2. Difference in appearance

The shell of the crayfish is hard and dark red, and stripes generally appear on the back, the juvenile shrimp is gray and has long chelera, while the lobster is red all over the body, with a large body, a thick shell, and a relatively clear texture.

3. Differences in living habits

Crayfish adapt to the strong rotation of tung trap, live in an environment of 10-30, like to eat some plankton, which can help crayfish fatten quickly, and most of the lobsters live in seawater, its body size, fast movement, low oxygen tolerance, like to eat planktonic mollusks and bait, lobster production is high.

Techniques needed to raise crayfish:

1. Scientific and reasonable fishing

Lobster harvesting must be determined according to the stocking season, but it is generally possible to fish in June-July and November-December each year. You can also catch the large lobster fishing ruler sail that has reached the market size first, and then continue to release new lobsters, so that you can catch lobsters all year round.

2. Do a good job of breeding planning in advance

If wild lobster species are introduced, they must be domesticated for a period of time in advance before stocking. Generally, the first year of crayfish breeding is mainly to do a good job in breeding, stocking shrimp seedlings is generally carried out in summer, and lobsters that grow up in the early stage of autumn and winter and spring are mainly stocked.

Lobsters are seafood that grows in the sea, and crayfish are freshwater creatures that are produced in ditches and canals. A pound of lobster costs more than 300 yuan, and crayfish costs 30 yuan.
