What is the difference between shrimp and base tailed shrimp, and what is the difference between chi

Penaeus orientalis, also known as Penaeus chinensis and giant shrimp. Arthropod phylum, Crustacea, Decapod, Shrimpidae, Shrimp genus. Shrimp is a large individual, commonly known as prawns.

The female grows up to 16 22 cm in length and weighs about 50 80 grams, and the largest can reach 30 centimeters and weigh 250 grams; Males are smaller, with a body length of 13 to 18 cm and a weight of 30 to 50 grams. Shrimp is a wide-temperature and wide-salt marine animal. The body of Penaeus vannamei is long and cylindrical, with flat left and right sides, and the body is divided into head, thorax and abdomen, and is composed of 20 segments.

The abdomen is long, muscular, and segmented distinctly.

Shrimp are saltwater shrimp with fatty flesh, delicious flavor, and rich in protein. Dissolve phlegm and relieve cough, clear milk and raw milk, aphrodisiac and waist, tonify kidney deficiency, and stomach, tonify kidney.

Metapenaeus ensis is also known as "base shrimp" and "new one-horned shrimp". Molluscs, prawns. The body length is about 8cm.

There are many sunken parts on the body surface, and short hairs grow on them. The frontal angle is straight, with only 7-9 teeth on the upper margin. The cephalothorax has a distinct branchial sulcus and branchial ridge, and the hepatic sulcus is distinct, with hepatic spines, antennal spines, and supraocular spines, and no buccal spines.

The first three pairs of foot feet have basal ganglion spines, the first step foot has base segment spines, the fifth step foot has no external limbs, the seventh thoracic segment has lateral gills, and the third foot has no limb gills. It is an important economic species and is the object of artificial breeding.

Jiwei shrimp is rich in nutrition, its meat is soft, easy to digest, and it is an excellent food for people who are weak and need to recuperate after illness; Shrimp is rich in magnesium, which can protect the cardiovascular system, it can reduce the level of cholesterol in the blood, prevent arteriosclerosis, and at the same time dilate the coronary arteries, which is conducive to preventing hypertension and myocardial infarction; Shrimp meat also has the effects of tonifying the kidney and strengthening yang, promoting milk and anti-toxin, nourishing blood and solidifying essence, dissolving stasis and detoxifying, nourishing qi and nourishing yang, relieving pain, appetizing and dissolving phlegm.

<> cocktail shrimp and jiwei shrimp.

There is no difference, its scientific name is the knife forehead of the new shrimp bridge sun.

It is mainly distributed in the southern coastal areas of China and has strong economic value. This shrimp has a wide range of adaptations to water bodies, can survive in low-salt water, and can also tolerate high temperatures and low dissolved oxygen. In captivity, it is generally fed 3-4 times a day, one third of the cong stove should be fed during the day, and two thirds of the osmotic elimination should be fed in the evening.

The differences between Penaeus vannamei and Jiwei shrimp are as follows:1. There are brownish stripes on the surface of Jiwei shrimp, and the shrimp tail also has patterns; The color of the shrimp body of Penaeus vannamei shrimp is more transparent, and there is no obvious pattern on the surface. If you compare them together, it's easy to see.

2. After cooking, the stripes on the Jiwei shrimp are still obvious, and the white shrimp has no patterns.

Litopenaeus vannamei shrimp, commonly known as white-limbed shrimp, resembles Chinese shrimp and Penaeus vannamei shrimp in appearance, and the average life span can be at least more than 32 months. The adult body can reach a length of 24 cm, the carapace is thin, the normal body color is light blue-gray, and the whole body does not have markings. The feet are often chalky, so they are called white-limbed shrimp.

It belongs to the subgenera of Arthopoda, Crustacean, Decapoda, Natantia, Penacidae and Penaeus.

Jiwei shrimp, generally refers to the knife forehead new shrimp, commonly known as sand shrimp, mud shrimp, belongs to the coastal shallow sea shrimp, mainly distributed in the southern coastal areas of China. In the offshore fields of these areas, a base fence is usually built to protect against flooding, and there is a type of shrimp that likes to swim with the tide to spawn in the area where the water flow is gentle under the base area, and people call this kind of shrimp "base shrimp".

Sea shrimp and Jiwei shrimp are actually very similar, but there are still certain differences, how to distinguish between sea shrimp and Jiwei shrimp?

If it is raised in fresh water, it should be desalinated shrimp seedlings, which can be raised in fresh water. Again, sea shrimp and river shrimp are all nutritious. It is generally believed that the nutritional value of sea shrimp is higher, and many marine species have desalinated seedlings, and now, freshwater aquaculture of marine species has been very common.

The shrimp is rich in nutrients, sweet and salty, slightly warm in nature, and rich in nutrients than the shrimp.

The shell of the shrimp is thick. When buying shrimp, as long as you pinch it gently, you will feel that the shell is relatively hard, and it is very elastic that it is shrimp. The calcium content of farmed shrimp should not be as good as that of sea shrimp, so the feeling of shrimp shell to the touch is that it will feel thinner.

A bunch of shrimp of different sizes is more likely to be, if the size is more symmetrical, it may be artificially farmed, that is, Jiwei shrimp.

1. Species differences.

In essence, they are not a species, the scientific name of shrimp is Penaeus orientalis, also known as Oriental prawn, green shrimp, yellow shrimp, etc., and is a genus of prawns in the family Litopenaeus. The scientific name of Jiwei shrimp is Litopenaeus knife, and the common name is more flower shrimp, tiger shrimp, red claw shrimp, etc., so its breeding method is collectively referred to as Jiwei shrimp in business.

2. Appearance difference.

The size of the shrimp is larger, generally 16-22 cm long, up to 30 cm, the weight is between 30-80 grams, the weight is half a catty, its abdomen is long, muscular, the shrimp body is long and cylindrical, and the left and right sides are flattened. Generally, adult shrimp female shrimp are larger than male shrimp, and their body color is also called that there will be a difference in limbs, the female shrimp body color is gray and green, and the male shrimp body color is yellow. The size of the shrimp is smaller than that of the shrimp, the body length is generally 10-15 kilograms, and the end of the shrimp is slightly red, which is the biggest difference with the shrimp, and they can be distinguished by it when buying.

3. Taste difference.

The two are more popular varieties among consumers on the market, the meat quality of shrimp is relatively elastic, chewy to eat, and the common cooking methods in life are salt, oil stew, barbecue, frying and so on. The biggest feature of Jiwei shrimp is that the shell is thin and the meat is fat, its shell is thinner, and the meat is more tender, which is suitable for boiling, soup, barbecue, etc.

4. Differences in breeding environment.

Shrimp is a kind of sea shrimp, for the breeding environment requirements are higher, water quality, substrate and breeding density have certain requirements, the cost of breeding it is relatively high, so the first is also relatively high. Although Jiwei shrimp is also a kind of sea shrimp, it has low requirements for the salt content of the water body, and can also be cultivated in the fresh water of the hall, which is suitable for inland aquaculture, and the scale of breeding is also larger, and it is slightly cheaper than the shrimp.

Although shrimp and Jiwei shrimp belong to shrimp, these two are still different, so what is the difference between shrimp and Jiwei shrimp?

The new shrimp is commonly known as hemp shrimp and Jiwei shrimp, and there are more people called Jiwei shrimp. Jiwei shrimp is freshwater breeding, seawater enclosure culture, and its name is due to "enclosure culture". Shrimp are mainly found in the Yellow Sea and Bohai Bay.

In the past, it was often paired in the market, so it was called prawns. Also called prawns.

Among all the shrimps, the taste of the shrimp is more delicious. Due to the fact that Chinese shrimp were infected by a viral infectious disease a few years ago, almost all of them were wiped out, and most of the artificially farmed shrimp on the market at present are South American white shrimp imported from abroad. Jiwei shrimp was originally a new shrimp cultivated in shrimp farms in Guangdong and other places, because its body length is generally seven or eight centimeters, and later people called this length of shrimp Jiwei shrimp.
