CATDOLL : CATDOLL: How to distinguish river crabs from sea crabs?

1. How to distinguish river crabs from sea crabs?

Distinguishing method:

1. Look at the appearance

There are many small hairs on the legs and claws of river crabs, but sea crabs do not. There are many types of sea crabs and their colors are different, while river crabs are mostly green and do not have bright colors.

2. Taste

Whether steamed or boiled, river crabs have very firm and delicate meat. Although sea crabs are large, their meat is relatively loose and not as delicious as river crabs. In terms of nutritional value, although both are crabs, sea crabs have higher nutritional value than river crabs.

Saltwater crabs that grow in the ocean are called sea crabs, while freshwater crabs that grow in inland waters such as lakes, ponds, and rice fields are called river crabs. Most of my country's sea crabs are naturally caught products, and are sold as frozen products after being caught during the flood season; river crabs are now mostly cultivated products, among which the Chinese mitten crab (commonly known as hairy crab) is the most famous, and is generally best eaten from the end of September to mid-December each year.

River crabs and sea crabs have their own nutritional advantages. Under the same weight, river crabs have higher content of vitamin A, vitamin B1, vitamin B2 and vitamin E than sea crabs, while calcium, potassium and magnesium are lower than sea crabs. As for cholesterol, which is of most concern to everyone, river crabs have more than twice the content of sea crabs.

It is important to note that crabs live at the bottom of the water and are omnivorous, mainly feeding on aquatic plants, small fish and shrimp, etc. Therefore, certain bacteria may infect the crabs, especially river crabs raised in eutrophic water bodies. Once the crabs die, the infected bacteria in their bodies will multiply in large numbers, and some bacteria may even produce toxins, so "problem crabs" are prone to food poisoning. Therefore, when purchasing crabs, you must pay attention to whether they are fresh, especially river crabs, which must be cooked and steamed thoroughly before eating.

Different living environments: meat crabs live in the sea and have the fattest meat among all sea crabs; while hairy crabs live in freshwater lakes and are considered river fish.

Different in size: In terms of size, meat crabs are obviously larger than hairy crabs.

Different taste: The meat of meat crabs is fuller, but the taste of hairy crabs is more delicious than that of meat crabs.

Meat crabs and hairy crabs: Because they are Yangcheng Lake crabs, the best among crabs, they are naturally more expensive. Yangcheng Lake hairy crabs are a specialty of Suzhou City, Jiangsu Province, and are also a geographical indication product in my country. They are produced in Yangcheng Lake in Suzhou. Crab meat is tender, delicious, and rich in nutrition. The protein content is several times higher than that of pork and fish, and the content of riboflavin, calcium, phosphorus, iron and vitamin A is also high.

The meat of hairy crab is delicious and has great nutritional value. And the production is very low. Scarcity makes things valuable. You get what you pay for. As a famous Jiangnan delicacy, people come from all directions when the crab season comes. After the chef's skillful hands, it successfully appears on our table. It has a fresh color and an attractive aroma. Look at its majestic body, open it in our hands and taste its fragrant crab meat. It is so refreshing.

These two parts are where the most meat is.

The meat of crab meat is the most beautiful. The meat of high-quality crab meat is plump, smooth, fresh and sweet, with a unique fragrance. After steaming, it is bright red, fragrant and delicious. It is also an indispensable delicacy.

Long ago, there were records of eating crabs in the Compendium of Materia Medica. my country has a long history of eating crabs. It is found that the river crabs grown in three regions of my country are of the best quality, namely the ancient Danyang Daze river crabs and Huajin crabs located in Jiangsu and Anhui provinces, the Baiyangdian river crabs in Hebei Shengfang crabs, and the Yangcheng Lake hairy crabs mentioned in this article. In any case, crabs are good as our food. Satisfy everyone's appetite.

4. Are Yangcheng Lake hairy crabs the same as river crabs? What are the differences?

They are different, the size is different, the taste is different, and the price difference is very large.

The two are grown in different places and have different natures. Their nutritional value and nutritional components are also different. The nutritional component of hairy crabs is higher, so hairy crabs taste better.

They are different; different colors, different living habits, different prices, different tastes, these are basically the differences.

In fact, the breeding history of Yangcheng Lake hairy crabs is not long. It should be said that the breeding of Yangcheng Lake hairy crabs began to become popular in the 1990s, but the fame of Yangcheng Lake hairy crabs has a long history. The difference between Yangcheng Lake hairy crabs and ordinary river crabs is indeed quite big. You don’t know until you eat them. But after tasting Yangcheng Lake hairy crabs, you will find that authentic Yangcheng Lake hairy crabs are definitely the best river crabs.

I think the biggest difference between Yangcheng Lake hairy crabs and ordinary river crabs is that Yangcheng Lake hairy crabs have a lot of crab roe, and the meat is tender and tastes very good. Yangcheng Lake is located in Suzhou City, Jiangsu Province, and is a land of fish and rice with a long history. The average water depth is about 2 meters, the water quality is pure, and the aquatic plants are lush, which is very suitable for the growth of hairy crabs.

In addition, with the improvement of the quality of life in my country in recent years, the hype of Yangcheng Lake hairy crabs has been increasing. In addition to the taste of Yangcheng Lake, this golden signboard makes Yangcheng Lake hairy crabs different from ordinary river crabs and hairy crabs, and the price is at least three times that of ordinary hairy crabs.

Due to the inflated prices and huge profit margins, many nouveau riche began to target this market and started their disgusting business. So if you want to eat authentic Yangcheng Lake hairy crabs, it is recommended to consult YUR0327 (VX) to learn about authentic Yangcheng Lake hairy crabs. Now many aquatic product companies are shameless, shipping ordinary hairy crabs into Yangcheng Lake one or two months in advance, and then selling them under the banner of authentic Yangcheng Lake hairy crabs after the Yangcheng Lake hairy crabs are sold. Therefore, the difficulty of buying authentic Yangcheng Lake hairy crabs is one of the differences between Yangcheng Lake hairy crabs and ordinary river crabs.

The production volume cannot meet the consumption, so the price rises. This indirectly raises the quality of hairy crabs to a higher level. It becomes a sincere choice for gifts. Other river crabs cannot be bought at this price, so Yangcheng Lake can be said to have a monopoly on the high-end market.

The surrounding hydrological conditions are favorable and the land is fertile and suitable for growth. That's why it became a hairy crab! The individual crabs are relatively large and rich in nutrients. Compared with other river crabs, they are of better quality.
