CATDOLL : CATDOLL: Which one is more expensive among prawns, white shrimps, and shrimps? Which one is the cheapest?

Which one is more expensive among prawns, white shrimps, green shrimps and shrimps? Which one is the cheapest?

Prawns are the most expensive and the tastiest among these types of shrimp. White shrimps and green shrimps are the cheapest, but it also depends on their size. If they are the same size, then prawns are the most expensive.

Green shrimp is the most expensive, I don't know which one is the cheapest

Prawns are loved by many diners because of their thin shells, fat bodies, delicious meat and a meat yield of up to 60-70%. At the same time, the protein content of shrimp meat is several to dozens of times higher than that of ordinary fish, and it is rich in minerals such as iodine, magnesium, and potassium. The high nutritional value also makes prawns a nutritious product.

I believe everyone has eaten the shrimp in the picture above, and many people love to eat it. So, what do you call the shrimp in the picture above? Prawns, shrimps or white shrimps? There are all kinds of names in the non-professional circle of shrimp lovers, but these three names appear most frequently, so we will focus on them.

In fact, they are three different kinds of shrimps that can be bought in the market. They look similar but their taste and price are very different.

Some small vendors in the market often take advantage of the similar appearance of these shrimps and the difficulty for non-professionals to distinguish them, and try to pass off fake shrimps as real ones (note: the mud shrimps sold for dozens of yuan per pound in the market are basically white shrimps). Therefore, in today's Shrimp Guest Lecture, the Shrimp Guest will break down and compare these shrimps for you, hoping to help you quickly distinguish, accurately express, and understand how to buy in the future.

1. Prawns (Penaeus chinensis)

The native shrimp of our great China, prawns are sea-caught prawns. Because they have very high requirements for water and bottom quality, it is difficult to breed them, the breeding density is low, and the cost of breeding is high, so the price remains high. And the bigger they are, the more expensive they are. Sea-caught prawns are basically sold by the piece (does it remind you of the story of Qingdao prawns?).

Appearance difference:

1. The spike on the head of the prawn (scientific name: sword-shaped spines) is very long, longer than the shrimp's mouth, and the shrimp's antennae are also exceptionally long.

2. Prawns are famous for their large size, the largest of the three types of shrimp. Especially female shrimps, which can be as large as 20 to 30 centimeters each, much larger than white shrimp and mud shrimp. Male shrimps are relatively small, but they are also more than 10 centimeters, still larger than white shrimp and much larger than mud shrimp.

2. Shrimp (Penaeus scaly-headed)

The skin of the shrimp is thin and the meat is tender, which is the best for blanching and making soup. The shrimp is obviously smaller than the white shrimp and is expensive. The market price has been maintained at around 100 yuan or even more for a long time, so it is common to pass off fake shrimp as real shrimp - white shrimps that cost dozens of yuan per pound are used to impersonate the shrimp.

Appearance difference:

1. Look at the forehead

The scientific name of the shrimp reveals an important appearance feature of the shrimp. Only the upper half of the shrimp's forehead has teeth, while the lower half is smooth. The sword has double edges, and the knife has only a single edge. Therefore, the scientific name of the shrimp is called Neopenaeus lanceolatus.

2. Look at the shrimp body and shrimp legs

The mud shrimp also has important appearance characteristics: the adult shrimp is yellowish, and the tips of the shrimp legs are a little red.

3. White shrimp (Penaeus vannamei)

It is a kind of saltwater shrimp originating from South America. As an entry-level seafood, its meat tastes similar to prawns, but its size is larger than that of shrimps. Therefore, it has become one of the three most productive shrimps in the world and the most common shrimp on the market. The most common size of white shrimp on the market is 30-50 heads (i.e. 30-50 per catty), with a thin shell and a normal body color of light blue-gray.

Seeing this, I will give you the key points and briefly summarize:

1. Prawns are large and expensive. They look similar to white shrimps, but have longer foreheads and are larger in size. Most importantly, they are much more expensive than white shrimps. Sea-caught prawns are basically sold individually.

2. The shrimp is small and expensive, with a slightly yellowish body. The easiest way to distinguish it is at the forehead, which has a knife-shaped forehead and teeth on one side. The Chinese shrimp and the whiteleg shrimp both have a sword-shaped forehead and teeth on both sides.

3. White shrimp are the most abundant, common and cheapest.

Normally, if you want to buy prawns or shrimps, you have to carefully distinguish whether there are white shrimps in it. When buying white shrimps, you don’t have to worry about buying prawns and shrimps. After all, Confucius once said: You can only buy the wrong one, not sell the wrong one.

But when buying white shrimp, choosing shrimp is also a skill. What kind of shrimp tastes better? What kind of shrimp can be stored? Why do some shrimps have visible shrimp threads, while others do not? In the near future, the shrimp guest will popularize science for everyone, how to choose the most beautiful shrimp, stay tuned, welcome to share.

What is the difference between prawns and shrimps?

the difference

1. Different living habits

Green shrimp is a pure freshwater shrimp, which is distributed almost all over the country. Among them, the ones produced in Baiyangdian area of ​​Hebei Province and Taihu Lake of Jiangsu Province are the most famous. There are two types of shrimps: sedentary and migratory. The former live in shallow coastal waters, often diving into the sandy bottom during the day and do not move over a large area; the latter live in turbid waters along estuaries and often move and migrate over a large area.

1. Different prices

The difference between red shrimp and green shrimp is also the size. Green shrimp is larger than red shrimp, and the price of the two is also very different. Green shrimp has tender meat and soft shell, but it is not easy to transport over long distances, and the mortality rate is higher than that of red shrimp.

2. Different colors

Red shrimps are called red shrimps because of their red skin. The difference between red shrimps and green shrimps is that red shrimps taste a bit earthy and not very fresh. Green shrimps are tender and delicious, rich in nutrition, and contain 16.40 grams of protein per 100 grams of edible part. Nutritionists believe that it has a certain brain-boosting function. Green shrimps taste fresher than red shrimps and do not have an earthy smell.

Nutritional Value

1. Shrimp is rich in nutrients, and its meat is soft and easy to digest. It is an excellent food for people who are weak or need recuperation after illness.

2. Shrimp is rich in magnesium, which plays an important regulatory role in heart activity and can protect the cardiovascular system very well. It can reduce the cholesterol content in the blood, prevent arteriosclerosis, and at the same time dilate the coronary arteries, which is beneficial for preventing hypertension and myocardial infarction.

3. Shrimp has a strong lactation effect and is rich in phosphorus and calcium, making it especially beneficial for children and pregnant women.

4. A very important substance in shrimp is astaxanthin, which is the red component on the surface. Astaxanthin is the strongest antioxidant discovered so far. The darker the color, the higher the astaxanthin content.

the difference

1. Different physical characteristics

Shrimp is an arthropod with a body length of 15-20 cm and a thin and transparent shell. The whiskers on the second pair of antennae are very long. The meat is delicious and is one of my country's specialties. It is mainly produced in the Yellow Sea and Bohai Bay. In the past, it was often sold in pairs in the market, so it is called prawns. It is also called prawns. Green shrimp, also known as river shrimp, is scientifically known as Japanese swamp shrimp. It is named because of its blue-green and translucent body color.

2. Different population distribution

Prawns are mainly distributed in the Yellow Sea and Bohai Sea in China, Lushun, Liaoning, Hebei, Shandong Province and the coastal areas of Tianjin. They are important production areas of prawns. Green shrimps are also called river shrimps, swamp shrimps, and Japanese swamp shrimps. They are a major economic shrimp species widely distributed in freshwater waters. They are rich in nutrients, tender and delicious, and are a precious aquatic product that is deeply loved by people. Green shrimps are widely distributed in my country, including Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Jiangxi, Guangdong, Hunan, Hubei, Sichuan, Hebei, Henan, Shandong Tianjin, Yunnan and other places. They live widely in freshwater lakes, rivers, ponds, and swamps. The green shrimps produced in Baiyangdian, Hebei Province, Taihu Lake, Jiangsu, and Weishan Lake, Shandong are the most famous.

3. Different ecological habits

Shrimp can be divided into sedentary types (such as Japanese shrimp, broad-grooved shrimp, European shrimp, Bohai shrimp, etc.) and migratory types (such as Chinese shrimp, black shrimp, long-haired shrimp). The former live in shallow coastal waters and often dive into the sandy bottom during the day without making large-scale movements; the latter live in turbid waters along estuaries and often move and migrate in large areas. Shrimp mainly feed on benthic invertebrates, such as polychaetes, small crustaceans and bivalve mollusks, and sometimes also catch zooplankton.

Macrobrachium sphaeroides are omnivorous aquatic animals, partial to animal feed, and are mainly fed with commercial feed in artificial breeding. The most suitable water temperature for their growth is 18-30℃. When the water temperature drops to 4℃, they enter the wintering period. When the water temperature rises above 10℃, their vitality increases and their feeding gradually increases. They live on the bottom and like to live in slow-flowing places with dense aquatic plants. The water depth they live in ranges from 1-2 meters to 6-7 meters. In summer and autumn, macrobrachium sphaeroides forage and reproduce in shallow waters near the shore. In winter, they move to deeper water areas to hibernate, and rarely eat or move.
