CATDOLL : CATDOLL: Where does the name of the shrimp come from?

In the coastal areas of southern my country, in order to prevent floods, local people built "diwei" to surround the coast; and a species of shrimp, "ma shrimp", likes to hide itself in the mud of the shallow sea during high tide. After fishermen discovered this characteristic of ma shrimp, they built diwei to catch ma shrimp; later, fishermen began to cultivate this kind of shrimp with seawater on the beach, and named it "diwei shrimp".

Unlike wild seafood, prawns are a type of marine cultured shrimp. They are also seafood products, but unlike general seafood, most of them are artificially cultured; while the seafood that people often talk about is naturally grown and artificially caught.

Additional information:

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 spurs, and the last pair of walking legs has no external limbs.

The morphological characteristics of the closely related Neopenaeus are similar to those of the knife-headed Neopenaeus, except that its abdominal swimming limbs are bright red, the male coupling is "Y"-shaped, the female coupling is "C"-shaped, and the central plate is table-shaped.

Wide-ranging temperature and salt content shrimp. Widely inhabits sandy, sandy muddy and muddy sea areas. It is distributed in coastal areas within a depth of 50 meters, and its number is larger within 10 meters. The water temperature range of the Neopenaeus lanceolatus is very wide. It is distributed in the sea area of ​​8-29°C. The best water temperature for breeding is 18-25°C.

The blade-headed shrimp is a euryhaline species, with a salinity range of 0‰ to 34‰. It has a very mixed diet, mainly preying on benthic organisms, and also feeding on bottom plankton and swimming organisms.

Because they like to swim with the tide to the area with slow current under the basal plate to lay eggs, they are called basal plate shrimp.

The mud shrimp belongs to the phylum Arthropoda, class Crustacea, order Decapoda, suborder Natura, family Penaeidae. The maximum body length can reach 19cm. It is a nearshore shallow sea shrimp. It has the advantages of strong omnivorousness, wide temperature and salt range, rapid growth, strong disease resistance, and can tolerate low oxygen and has the habit of lurking at the bottom. It is deeply favored by consumers because of its thin shell, fat body, tender and delicious meat, and can be sold live. It is currently an excellent variety of "marine shrimp light farming".

Morphological characteristics

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 have longitudinal ridges, and the tail segment has no lateral spines. The first pair of walking legs have pedicels, and the last pair of walking legs do not have external limbs. The morphological characteristics of the closely related new shrimp are similar to those of the knife-headed new shrimp, except that its swimming limbs on the abdomen are bright red, the male receiver is "Y" shaped, the female receiver is "C" shaped, and the central plate is table-shaped.

Living habits:

Wide temperature and salinity:

Shrimp. They live widely in sandy, sandy muddy and muddy sea areas, and are distributed in coastal areas within a depth of 50 meters, but are more numerous within 10 meters.

The water temperature adaptability of Penaeus razorbackii is very wide, and it is distributed in the sea area of ​​8-29°C. The best water temperature for breeding is 18-25°C. Penaeus razorbackii is a wide-salinity species, and the salinity range can be between 0‰ and 34‰. It has a very mixed diet, mainly preying on benthic organisms, and also eating bottom plankton and swimming organisms.

Because shrimp like to lay eggs in the dikes built around farmland.

The main distribution of the muddy or muddy bottom sea area along the coast of Fujian, Taiwan, Guangdong and Guangxi in my country. In the coastal areas of southern my country, people also plant farmland. In order to prevent floods, people build embankments around farmland, which are called "muddy embankments". The muddy shrimp likes to swim with the tide to the gentle water flow area under the muddy embankment to lay eggs, so it is also called "muddy shrimp".

The shrimp likes to lurk in sandy or muddy bottom sea areas, preferring to show only two eyes and tentacles. It has a strong ability to adapt to the environment. Although it belongs to saltwater shrimp, it can also survive in semi-salt water and can survive for a long time out of water.

Nutritional value of shrimp

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 to recuperate after illness.

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

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

4. Scientists at Osaka University in Japan recently discovered that astaxanthin in shrimp can help eliminate jet lag caused by jet lag.

In Guangdong, offshore fields are surrounded by dikes to prevent flooding. Shrimp like to swim with the tide to the gentle current area under the dike to lay eggs, so they are called dike shrimp.

Metapenaeus ensis is also called "basic shrimp" and "unicorn shrimp". It belongs to the class of soft armor and the family of Penaeidae. It is about 8cm long. There are many concave parts on the body surface, which are covered with short hairs. The forehead is straight, with only 7-9 teeth on the upper edge. The cephalothorax has obvious cardiobranchial grooves and cardiobranchial ridges, obvious hepatic grooves, hepatic spines, antennal spines and supraorbital spines, and no cheek spines. The first three pairs of walking legs have basal spines, the first leg has a sacral spine, the fifth walking leg has no external limbs, the seventh thoracic segment has lateral gills, and the third maxilla has no limb gills. It is an important economic species and is the object of artificial breeding.

Bamboo shrimp is a kind of shrimp bred in freshwater, cultivated in seawater, and cultivated artificially for food. It is called Bi Tan Bamboo Shrimp. It gets its name from "cultivated in enclosures" and is generally not big in size. This is the only difference between it and ordinary bamboo shrimp.
