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.

1. The variety is different from the first; 2. Different nutritional value.
1. Big Flower Dragon: The front and back of the head and chest armor are clear eggplant with color patterns, the body size is larger, each only 5 to 7 catties, you can make a lobster head with soy pepper, soak lobster balls in oil on the flesh, and then cook lobster soup at the tail. Generally, the first and second years of the year are high, because it is said that the business of eating flowers and dragons will be prosperous during the New Year, and the dragon spirit and tiger are fierce.
Da Qinglong: It's small, it's all shells, it's not delicious, and it's not cheap.
2. Big Flower Dragon: The lobster in the ocean is rich in protein, minerals and vitamins A and C, and the fat content is very low, which has the effects of tonifying the kidney and strengthening yang, nourishing blood and consolidating essence, dissolving stasis and detoxifying, nourishing qi and nourishing yang, and relieving pain in the main shed of the Tongluo key. Da Qinglong:
Rich in protein, with the ability to maintain potassium and sodium balance; Eliminates edema. Boosts immunity. Regulate blood pressure, buffer anemia, and be conducive to growth and development.
Both the flower dragon and the green dragon are extremely delicious foods.

The biggest difference between lobster and crayfish is that the area is different. 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.

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.

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.
Vinegar + salt: When cleaning lobsters, we need to choose the right cleaning supplies, at this time, you can put the carefully selected crayfish in water mixed with vinegar and salt to soak for 15 minutes, forcing the lobster to spit out the dirt on the cheeks. After soaking, the crayfish is basically very clean, at this time rinse with clean water 3 times, and it can be sent to the kitchen. >>>More
Crayfish is not recommended to be eaten overnight. Crayfish is rich in protein, protein is easy to denature, may produce protein degradation substances during the overnight period, may damage the human liver, gastrointestinal and other organs, eating overnight crayfish may cause diarrhea, abdominal pain and other symptoms. Crayfish also contain high levels of purines, and if consumed too much, it may aggravate the uric acid content in the body, causing gout or aggravating gout.
Lobsters are divided into freshwater seawater, and lobsters that grow in the sea are seafood, and those that grow in freshwater are not seafood. >>>More
Crayfish and pineapple are not recommended to be taken at the same time, and those with allergies should not eat them. And because the oxalic acid in pineapple will turn into calcium oxalate, it is easy to cause symptoms such as bloating or stomach bloating! The two should be separated by at least half an hour.
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.
