What kind of shrimp is Penaeus monodon? What are the morphological characteristics and where are the

Penaeus monodon is the largest individual in the shrimp genus, also known as nine-node shrimp, flower shrimp, ghost stick shrimp, etc., in the biological classification belongs to the biological kingdom, arthropods, molluscs, decapods, shrimp family, shrimp crustaceans, generally 350 400 grams of individuals, larger individuals up to 500 grams, with strong edible value and economic value.

The epidermis of Penaeus monodon is smooth, the shell is slightly thicker, the body color of the fish is reddish-brown, light brown, dark cyan or light green, there are 9 white transverse bands on the body, the forehead is straight, the end is thick, slightly bent upward, the cephalothorax has tentacle grooves, cervical grooves, tentacle spines, liver spines, gastric spines, the 1st and 4th pairs of feet have outer limbs, the 5th pair of feet have no outer limbs, the tail segment is slightly better at the 6th segment, the tail end is pointed, and there are no lateral edge spines.

Penaeus monodon is widely distributed in Asia, Europe, Africa, Oceania and North America, including China, India, Pakistan, Sri Lanka, Malaysia, Thailand, Australia, Japan and other places, and China is mainly distributed in Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Hainan and other places, especially in the eastern, southern, southwestern and Qiongzhou of Hainan Island.

Environment: Penaeus monodon is a marine crustacean, adult shrimp live in muddy or sandy deep sea, inhabit the deep depth of generally within 60 meters, young shrimp and juvenile shrimp live in shallow water along the coast, often a large number of clusters in the middle of aquatic weeds or adherent weeds.

Carnivorous: Penaeus monodon is omnivorous, of which animal food is mainly bivalves, monovalves, long tails, short tails, rotifers, etc., small fish species, etc., and plant foods are mainly algae and branches and leaves, fruits, and debris of aquatic flowers.

Breeding: Penaeus monodon is an oviparous shellfish, dioecious, test-tube baby, the breeding season is 3 November, with 7 September as the peak period, the female shrimp is pregnant with 30 1.2 million eggs, the water temperature is 27 29, and the salinity is 29 and hatches into nauplii in about 20 hours.

In terms of price, the giant shrimp will naturally be scarce and expensive due to the strict regulations of the growing environment. Therefore, the price of giant shrimp is a little expensive. In most areas, the price of giant shrimp basically fluctuates around 120 yuan a catty.

The price of grass shrimp is already relatively cost-effective, and it can be bought at about 30 yuan.

Giant prawn, also known as black tiger prawn. Judging from the appearance of the giant shrimp, it has obvious red and yellow lines, which is also a major feature of the giant shrimp. But in the case of grass shrimp, you can only see the horizontal texture on the grass shrimp, which is quite average.

Penaeus monodon has a smooth skin, a slightly thicker shell, and a reddish-brown and light brown body color, which is widely distributed in Asia, Europe, Africa, Oceania and North America, including China, India, Pakistan, Sri Lanka, Malaysia, Thailand, Australia, Japan and other places.

It belongs to the giant shrimp and is mostly distributed in India, Sri Lanka, Pakistan, Thailand, and Australia.

The body is slightly flattened, the carapace is thicker, and it generally grows in places with a lot of seaweed.

Spotted shrimp are sea shrimps. Spotted shrimp is a saltwater species that belongs to the family of marine shrimp. Giant shrimp is mostly produced in domestic and foreign areas, including foreign production in the Philippines, Thailand, India, Australia, Indonesia, the east coast of Africa and other places, and mainly in China's coastal areas.

Nutritional value of giant shrimp:In addition to being the same as ordinary shrimp, the content of astaxanthin is about 20% higher than that of ordinary shrimp, so it is relatively high during the Spring Festival, astaxanthin is one of the strongest antioxidants, which itself can significantly enhance the survival rate and spawning rate of shrimp, as well as the ability to resist the harsh environment outside.

Similarly, the consumption of shrimp meat high in astaxanthin in humans and animals can also significantly improve diseases such as atherosclerosis.

Spotted shrimp belongs to the category of marine shrimp. It is found off the coast of China, southern Japan, south Korea, the Philippines, Indonesia, Australia, Thailand, India and the eastern coast of Africa. The spawning period of giant shrimp is from February to April and August to November in China's coastal areas every year.

Mature giant shrimp are generally centimeters long and weigh 137-211 grams. The largest specimen found so far is up to 33 centimeters long and weighs 500-600 grams.

Features:

The giant shrimp has fast growth, strong adaptability, and mixed diet, and has low requirements for the protein content of the bait, only about 35%, and can tolerate a wide range of salinity and temperature. The salinity ranges from 10% to 20% for optimum salinity; The optimum temperature is 25 -32 and it is more tolerant to low oxygen.

Wild-caught monodon shrimp are generally very large in size and are mainly caught by bottom trawling. The artificially bred monodon shrimp are generally small in size when they are marketed due to their slow growth and long breeding cycle.

The body of the shrimp is long and slightly flattened, dioecious, and the adult female shrimp is larger than the male shrimp, and the body color is also different; The body color of the female shrimp of Penaeus chinensis is gray and green, and the body color of the male shrimp is yellow. The shrimp body is covered with a chitin exoskeleton carapace, which is secreted by the epidermal cells underneath it.

The body of the shrimp can be divided into cephalothorax and abdomen, with a total of 21 segments. With the exception of the anterior and last segments, each segment has a pair of appendages.

1. Some of these small shrimps are transparent and glass-like, which is grown up by Tongju; Some are a little gray-black, and even have mud on their backs and tails, and moss, which is old, and everyone calls it a thousand-year-old shrimp.

2. They are very careful when eating, always touching the food lightly with tongs first, then quickly retreating, then touching again, and retreating again until they feel that there is no danger, and then use two tongs to hold the food and eat. The well-fed shrimp seem to be very comfortable, some swim around alone, some chase each other, and some rest close to the tank wall.

3. The shrimp in the tank are very interesting. Some of them swing around alone, some chase each other, and some cling to the walls of the tank. If you use a small bamboo branch to move the small shrimp that are resting, they will immediately jump to another quiet corner, as if they are angry, and keep dancing the slender feet in front of them along the way.

4. The pair of pliers at the end of the feet are one by one, and the beard is swinging one by one, and even the eyeballs are protruding. If you run into a companion who is wandering around in a casual game, you may have to fight. The fight of the shrimp is very fierce, and it is not uncommon for them to jump out of the water, and sometimes they will jump to the ground outside the tank.

5. Sometimes a fallen leaf on the grape trellis falls into the tank, and after a while, many small shrimp will gather under the leaves.
