◆Arctic shrimp◆

Also called Arctic sweet shrimp. It is named because it is produced in the sea near the Arctic and has a faint sweet taste

◆Jiwei shrimp◆

The new shrimp is commonly known as hemp shrimp and Jiwei shrimp. It is more popularly known as Jiwei shrimp. Shrimp are bred in freshwater and raised in seawater. The reason for their name is "enclosed culture". The shape of the prawn is like that of a prawn, but its shell is softer than that of a prawn, and its body is not as big as that of a prawn. It is generally as big as the middle finger. The yield is higher in the estuary areas along the coast of Guangdong, and its body is fat and the shell is thin, and the meat is delicious and delicious. Juvenile shrimps (no more than 6cm) are dark green to dark green, and adult shrimps (above 6cm) are light brown, with their bodies covered with dense light brown spots. Some js on the market use white shrimp (prawn) to pretend to be prawns. When choosing, you should pay attention to: first, look at the color, and second, look at the spots. It's easy to identify.

◆Prawn◆

Arthropod, with a body length of 15-20 cm and a thin and transparent carapace. The barbels on the second pair of antennae are very long. The meat is delicious and is one of our country's specialties. Mainly produced in the Yellow Sea and Bohai Bay. In the past, they were often sold in pairs in the market, so they were called prawns. Also called prawns.

Penae shrimp is a genus of the family Penaeidae in the superfamily Penaeidae of the order Decapoda. There are 28 species in the world, 7 species in the Atlantic coast of America, 6 species in the Pacific coast, 14 species in the Indo-Western Pacific, 1 species in the Pacific and Mediterranean, and 1 species in West Africa. There are 10 species in China, inhabiting tropical and subtropical shallow seas. The genus Penaeus is large in size and is commonly known as prawn. The growing females are generally 16 to 22 cm long and weigh about 50 to 80 grams. The largest ones can reach 30 cm and weigh 250 grams. The males are smaller, with a body length of 13 to 18 cm and a weight of 30 to 50 grams. In northern China, they are often sold in pairs, so they are called prawns. According to ecological habits, shrimps can be divided into resident types (such as Japanese shrimps, broad-channeled shrimps, European shrimps, etc.) and migratory types (such as Chinese shrimps, Mexican shrimps, and long-haired shrimps). The former type lives in shallow coastal waters and often dives during the day. They do not move on a large scale in the sandy bottom; the latter species inhabit the turbid waters along the estuaries and often move and migrate on a large scale. Prawns mainly feed on benthic invertebrates, such as polychaetes, small crustaceans and bivalve molluscs, and sometimes zooplankton. The most special species of the genus Penaeus is Penaeus sinensis, which is distributed in the edge areas of subtropical waters. It has strong adaptability to the environment and has the habit of long-distance migration. Under temperature conditions below 10°C and above 30°C, Still able to survive. Spawning sites are located near river mouths and in low-salinity sea areas along the coast. They breed and lay eggs around May in the Yellow and Bohai Sea. The fertilized eggs hatch into nauplii. The body is oval, unsegmented, and has only 3 pairs of appendages. It has no resemblance to adult shrimps. After six molts, it becomes It is a flea-like larvae; it molts three times to become a mysid shrimp larvae, and then molts three times to become a juvenile shrimp. Its morphological structure is similar to that of an adult, with a body length of less than 5 mm. It lives a floating life and molts several times before sinking. Live under the sea. Larvae are often concentrated in low-salt waters of estuaries and intertidal zones. They can enter the estuary and return to shallow seas after reaching a body length of 30 mm. The larvae grow rapidly and can mate by the end of October. The males stuff their sperm pods into In the female's copulatory organ, after about 5 months of winter, fertilization and development will occur when the eggs are reproduced and laid in May of the second year. Prawns are warm-water species and cannot adapt to low water temperatures. After long-distance migration, they migrate to the deeper waters of the southern Yellow Sea to overwinter. They gather in large groups in late autumn before migrating, creating favorable fishing conditions and fishing seasons. The world's annual shrimp production is 300,000 to 400,000 tons, occupying an important position in marine fisheries. At present, shrimp farming production is developing rapidly around the world. China's shrimp farming output reached more than 80,000 tons in 1986. In 1986, the aquaculture production of Penaeus monodon in Taiwan alone exceeded 40,000 tons.

Really delicious. Prawns come in all sizes and are marinated in garlic, lemon oil or peri-peri. Prawns are cheap and you should try them at least once during your trip. South Africa imports most of its prawns from neighboring Mozambique to the north. Mozambique was a former Portuguese colony.

◆Green shrimp ◆

Green shrimp, also known as river shrimp, scientific name is Macrobrachium japonicum. It is named because of its blue and translucent body color.

Plain shrimp has a wide distribution, strong adaptability, high fecundity, miscellaneous feeding habits, and fast growth. In addition, the meat is tender, delicious, nutritious, and has high protein content (according to analysis, per 100 grams of fresh shrimp meat , containing 16.4 grams of protein, 1.3 grams of fat, 0.1 grams of carbohydrates, 1.2 grams of ash, 99 mg of calcium, 205 mg of phosphorus, 1.3 mg of iron), and also contains a variety of vitamins that are indispensable to the human body, so it is very popular among consumers. . Green shrimp is a year-round consumption species with no seasonal restrictions. Its processing and cooking methods are diverse and its taste is adaptable. Therefore, the supply of green shrimp has been in short supply in the market for many years, and its sales continue to increase. The price continues to rise. It is a kind of Breeding species with great market potential. Vigorously developing the artificial breeding of fresh shrimps is not only an important measure to adjust the fishery structure and promote the fishery to a new level, but also opens up a new way to get rich for the majority of fishermen (farmers).

River shrimp is generally a general term, but sometimes it also refers to grass shrimp. The grass shrimp has two claws that are extremely long, exceeding the length of the body. Therefore, it can only move forward or backward, and it is inconvenient to move left and right. The body color is dark green.
