Yellow shrimp is male shrimp, cyan shrimp is female shrimp, sea-caught non-cultured Chinese shrimp is generally 30 grams-50 grams, the larger the size, the rarer; The braised prawns made with this shrimp are the most classic and famous food, and the thin shell shrimp meat is crispy and soft, and the aftertaste is long.

Shrimp (scientific name Oriental prawn, also known as Chinese prawn, Chinese prawn and giant prawn) is a shrimp of the phylum Arthropoda, Mollusc, Decapod, Shrimp family, and Litopenaeus vulgaris. Shrimp is a large individual, commonly known as prawns.

Commonly known as prawns, prawns, green prawns (female), yellow shrimp (male), mainly produced 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.

The blood of shrimp does not contain hemoglobin (containing iron), but contains hemocyanin (containing copper), so the blood is blue, and the blood of shrimp mainly relies on divalent copper ions as a carrier to transport oxygen, and divalent copper ions are blue, and the blood of natural shrimp is blue.

To put it simply, prawns are a type of shrimp that used to be used as ingredients often paired **, so they are now called prawns.

White shrimp is freshwater shrimp.

White shrimp is a shrimp that lives in temperate and tropical coastal and freshwater, most of which have high economic value, live in shallow seas, near shore or near estuaries, and are widely distributed in the Indo-Western Pacific, coastal areas and lakes in China.

White shrimp is also known as Huang shrimp, river bald, spring shrimp, the whole body is covered with a carapace, the body is white and transparent, there are slight blue or red small spots, the shell is very slow and thin, but relatively hard, the shrimp body is slightly flattened, and the shell ridge is slightly edged.

Types of white shrimp

1. Spinal tail white shrimp.

The spinetail white shrimp has strong adaptability to the environment, grows and reproduces quickly, and its production is second only to that of Chinese hairy shrimp and Chinese shrimp along the coasts of the Yellow Sea and Bohai Sea.

2. Beautiful white shrimp.

It is a species that lives in pure freshwater and is found in the waters north of China. The breeding season in eastern and northern China is 4 October.

3. Ann's white shrimp.

Anstelleur's white shrimp is only produced in the coastal areas of China, living in brackish waters or pure fresh water near the estuary, the breeding season is between summer and autumn, the yield is not large, there is a certain amount near the Yangtze River estuary, mostly mixed with the spine-tailed white shrimp caught.

4. Oriental white shrimp.

Oriental white shrimp is common in the southeastern provinces of China and the coasts of Japan and North Korea, but the production is not large.

<> shrimp is a kind of shrimp belonging to the phylum Arthropods, molluscs, decapods, shrimpidae, and shrimp genus, also known as Chinese shrimp, Chinese prawn, and Oriental prawn.

1. Morphological characteristics

1. The body is composed of cephalothorax and abdomen, of which the cephalothorax is formed by the healing of 6 segments of the head and 8 segments of the chest, covered with a hard cephalothorax, and the front end has a straight and forward, slender and sharp frontal horn, the frontal horn is flattened, and the upper and lower edges have short teeth.

2. The abdomen is composed of 7 segments, the first 5 segments are relatively short, and the 6th segment is longer. The appendages are composed of abuttal, inner and outer limbs, and the number is 19 pairs.

3. The function of the mouthpart appendage is to hold and chew food, the role of the chest appendage is to prey and crawl, and the function of the abdominal appendage is to swim.

2. Habits

1. Environment. (1) Sedentary shrimp: including Bohai shrimp, Penaeus vannamei, Japanese shrimp, European shrimp, etc., often inhabit the shallow coastal sea, lurking on the sandy bottom during the day, and do not move in a large area.

2) Migratory shrimp: including Chinese shrimp, Penaeus vannamei and Penaeus longiaeus, which often inhabit along estuaries (or turbid sea areas) and often move and migrate in a large area.

2. Eating habits. It is an omnivore, likes to be active at night, foraging, and feeds on polychaetes, small crustaceans, and bivalves in the natural environment, and sometimes feeds on zooplankton and decaying animal carcasses.

3. Reproduction. (1) Shrimp is an oviparous animal, dioecious, female shrimp mostly spawn at night, and the spawning amount can usually reach about 10-200,000 grains.

2) After the female shrimp lays eggs, there are still regenerated eggs of different sizes in the ovaries, and the ovaries can lay eggs again after they mature.
