CATDOLL : CATDOLL: It is said that the shrimps sold at dozens of yuan per pound in the market are basically impersonated white shrimps. So what are the differences between them?

Among all sea shrimps, prawns are more delicious. Since Chinese prawns were almost wiped out by a viral infectious disease a few years ago, most of the artificially cultivated prawns on the market are whiteleg shrimps imported from abroad. The mud shrimp was originally a new type of prawn cultivated in shrimp farms in Guangdong and other places. Since its body length is generally seven or eight centimeters, people later uniformly called shrimps of this length mud shrimp.

Whiteleg shrimp

The most obvious feature of a healthy white shrimp is that its body is pure white and transparent, with only a red band on the outer edge of the tail fan (this is the most obvious feature of white shrimp), and the two long whiskers at the front are pink. The tail umbrella of the blue shrimp is blue, the two long whiskers are brown, and the body color is closer to dark brown than that of the white shrimp. If you observe carefully, you will find that the shell of the white shrimp is densely covered with fine spots, especially on the 2-5 cm young shrimp.

What is the difference between prawns and shrimps?

1. Juvenile shrimps are dark green to dark green, while adults (over 6 cm) are light brown with dense light brown spots all over their bodies. When choosing, look at the color and spots first. It is easy to identify.

2. The tail of the mud shrimp is colorful and looks very beautiful when unfolded. The tail of the white shrimp is white-gray. When choosing mud shrimp, you must choose green and slightly red ones, which are the best. If the merchant sells you black ones, don't buy them, because they are mud shrimp of very poor quality. 3. If there are thorns on the forehead of the shrimp, it is definitely not mud shrimp. There is a long red ridge on the back of mud shrimp, while only a small section can be seen in the back of the prawn.

What are the appearance characteristics of shrimps and prawns?

Morphological characteristics of shrimp

The body is light brown, with 6 to 9 teeth on the upper margin of the forehead and no teeth on the lower margin. There is no central groove, the whip on the first antenna is about 1/2 of the cephalothorax, the back of the 1st to 6th abdominal segments has longitudinal ridges, and the tail segment has no lateral spines. The first pair of walking legs has pedicels, and the last pair of walking legs has no external limbs.

Morphological characteristics of shrimp

Shrimp belongs to the phylum Arthropoda, subphylum Branchiophylum, class Crustacea, subclass Macula, order Decapoda, suborder Natura, family Penaeidae, genus Penaeus. Chinese Qi Na shrimp is one of the main species of the genus Penaeus, commonly known as "shrimp".

The body of the shrimp is long and slightly flattened. The sexes are different. The adult female shrimp is larger than the male shrimp and has different body colors. The female Chinese shrimp has a gray-green body color, while the male shrimp has a yellow body color. The body of the shrimp is covered with a layer of chitinous exoskeleton carapace, which is secreted by the epidermal cells below it. The body of the shrimp can be divided into the cephalothorax and abdomen, with a total of 21 segments. Except for the first and last segments, each segment has a pair of appendages.

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, 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 fact that these shrimps look similar and are difficult for non-professionals to distinguish, and try to pass off fake shrimps as genuine ones (note: the shrimps sold for dozens of yuan per pound in the market are basically white shrimps).

Prawns are big and expensive. They look similar to white shrimps, but have longer foreheads and are larger in size. Most importantly, their price far exceeds that of white shrimps. Sea-caught prawns are basically sold individually.

The mud 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.

White shrimp are the most abundant, common and cheapest.

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

I hope these corrections and answers can help you!

They have different appearances and different tastes, so you need to be careful when buying.

There is definitely a difference in taste and appearance, but the difference should not be that big.

There is no difference in appearance, but the taste is much different.
