A complete list of various types of shrimp, foodies who like shrimp, how many do you know?Time of issue : 2019-12-11
There are many kinds of shrimp, wild, farmed, deep-sea, shallow-sea, and imported. There are many kinds. Shrimp eaters, there are several you know, which one do you like?
[Place name] prawn, prawn, meat shrimp, yellow shrimp (male), green shrimp (female shrimp), prawn.
[Morphological characteristics] The body grows large and flat on the side. The female body is 18 to 24 cm long, and the male body is 13 to 17 cm long. The carapace is thin, smooth and transparent, the female body is blue-blue, and the male body is brownish yellow. Female individuals are usually larger than males. The whole body of the prawn is composed of 20 knots, 5 knots for the head, 8 knots for the chest, and 7 knots for the abdomen. Except for the tail section, each section has a pair of appendages. There are 5 pairs of feet, the first 3 pairs are clamp-like, and the rear 2 pairs are claw-like. The center of the front edge of the head breastplate protrudes to form the frontal horn. The upper and lower edges of the forehead are serrated.
[Origin, season] Mainly distributed in the Yellow Sea and Bohai Sea in China and the western coast of North Korea. China's Liaoning, Hebei, Shandong Province and Tianjin's coastal areas are important prawn production areas. In the past, the fishing season was divided into two seasons, spring and autumn, with spring flood from April to June; autumn flood from September to October. The mid-to-late October is the peak flood season.
At the end of 70 years, Chinese aquatic science and technology workers broke through the artificial breeding technology of prawns and solved the problem of artificially cultured prawns. At present, the Chinese shrimp farming production has been carried out on the coast of China from Dandong City in the north to the coast of Hainan in the south. The output is about 200,000 tons, which greatly exceeds the fishing volume in natural waters.
[Economic value] Fresh food can cook red braised prawns, fried prawns, prawns, pipa prawns, fried shrimps, etc. It is processed into dried seafood, dried shrimps, etc. which are excellent seafood. Chinese shrimp is the main product of China's aquatic products exports.
[Place name] grass shrimp, flower shrimp, beef-shaped shrimp. The Food and Agriculture Organization of the United Nations is known as the giant tiger prawn.
[Morphological characteristics] The body is dark brown and khaki horizontal stripes pattern. The upper margin of the frontal angle is 7-8 teeth, and the lower margin is 2-3 teeth. The frontal lateral sulcus is quite deep, extending behind the upper thorn of the eye, but the frontal lateral spine is lower and blunt, and the central sulcus of the posterior frontal ridge is obvious. There are obvious liver ridges and no stomach ridges.
[Origin, season] The distribution area is very wide, from southern Japan, South Korea, China's coast, the Philippines, Indonesia, Australia, Thailand, India to the east coast of Africa. There are two spawning periods in China's coastal areas from February to April and August to November each year.
[Economic Value] is currently the most common breed in the world. Two crops can be raised along the southern coast of my country. The shrimp grows fast, has strong adaptability, and has a variety of eating habits. It can tolerate a long time of dry dew, so it is easy to work and sell. The shrimp is the largest individual in prawns. The largest individual found is 33 cm long and weighs 500 to 600 grams. Mature shrimp are generally 22.5 to 32 cm long and weigh 137 to 211 grams, and are popular among consumers. The nutritional value is similar to other major shrimps.
[Place name] Prawns, White Prawns, Red Tail Prawns, Red Prawns, Daming Prawns, the United Nations Food and Agriculture Organization is commonly known as Red Tail Prawns.
[Morphological characteristics] The body is light brownish yellow, with 7-8 teeth on the upper edge of the frontal horn and 4-6 teeth on the lower edge. The lateral view of the base of the frontal horn is higher than that of the Chinese prawn and lower than that of the prawn Mochi. The posterior ridge of the frontal horn extends to the vicinity of the posterior edge of the head breastplate without a central groove. The first antennae whip is slightly longer than the head breastplate. The male prawns have long brush-like long hairs on the third palate, which is 1.2 to 2.7 times the length of the second section. There are intermittent depressions on the frontal ridge. The warts on the top of the front piece of the female connector are smaller than those of Penaeid Mochi.
[Origin, season] Mainly distributed in the Indian Ocean and the western Pacific from Pakistan to Indonesia. China's Fujian, Taiwan and the eastern coast of Guangdong are the most common. The sea fishing season is from October to January each year. At present, it is the
Tips to go to the shrimp lineTime of issue : 2019-12-11
Method / Step
Prepare a toothpick to pick the shrimp line. Use a toothpick to pass through the shrimp body from the joint of the shrimp head and shrimp body to the third joint (the joint of the shrimp head and shrimp body is counted as one joint)
Tips to go to the shrimp line
Take the shrimp in one hand and the toothpick in the other hand and gently pick out the shrimp line to pick it out.
The result of picking is generally that the shrimp line near the side of the shrimp head will be selected first
Slowly pull the shrimp line by hand, the end of the shrimp line near the tail will be pulled out
There is a super sharp thorn in the middle of the top of the shrimp head, be sure to cut it off, otherwise be careful to stab the hand or mouth
Use scissors to cut the joint between shrimp head and shrimp body
Use a toothpick to rinse the black tissues of the head while picking up the water pipe. Some internal organs are concentrated here, and there are sandbags, which are also dirty parts.
Compare the untreated shrimp, cut off the shrimp's whiskers, shrimp spines, shrimp feet, pick the shrimp line, clear the internal organs of the head.

How to eat oysters
Wash the fresh oysters in boiling water, rinse and blanched, dipped in seafood juice or spicy soy sauce containing ginger and pepper.
Tang burning oysters: use ham, chicken, scallops, lean meat to cook for 3 hours, and add peony, green onion, wolfberry and other ingredients. The alcohol stove ignites the broth. According to personal preference, raw oysters can be eaten raw, dipped in Japanese mustard, or they can be served with fresh flavorings.
The practice of ginger onion iron plate oysters: first peel the oysters, wash and cut them, then boil them until they are eight mature and drain them. Use Cantonese shallots and ginger to saute for 3 minutes. Drop the oysters on the iron plate and drizzle with hot oil.
How to cook oysters in Thai sauce: Wash the oysters and marinate them with ginger wine and seasoning for 5 minutes. Cook on the pan. Drizzle with Thai juice.
The practice of natural oyster soup: Wash 60 grams of fresh oyster meat and cut into small pieces. Wash laver into a large bowl, add clear soup, oyster slices, green onion, fine ginger shreds, steam in a steamer for 30 minutes. Remove and add refined salt, monosodium glutamate, pepper, Shaoxing and mix thoroughly.
How to wash oysters
You can use tap water for cleaning. The oyster meat is easy to rot. It is not recommended to keep it for too long. It is best to eat it as soon as possible.
Oysters generally don't need to let them spit. When cleaning oysters, it is best to wear latex gloves, put the oysters in water, and use a brush to clean the mud attached to the oyster shell.
If you buy fresh oyster meat, which is often mixed with broken oyster shells or other impurities, as long as the appropriate amount of vegetable oil (peanut oil) is dripped into it, it is easier to clean it.
It depends on which kind of oyster you are. If it is half-shell oyster (frozen), you do n’t need to wash it. If you think it is not clean, you can rinse it with tap water; Edible.
Conclusion: Raw oysters can not only play a tonic role, but also calm the mind and brain. There are many ways to eat oysters, you can eat them raw, stir-fried and simmer soup. When cleaning oysters, we should pay attention to wearing latex gloves, and then brushing the mud on the shell.
Ten Hot Issues in the Global Shrimp IndustryTime of issue : 2019-12-11
In 2017, total global shrimp production exceeded 4.3 million tons, an increase of approximately 7.5% year-on-year. Among them, China, India, Ecuador, Vietnam, Thailand, Indonesia and other six major producing countries exceeded 80% of global shrimp production. More than 80% of China's farmed shrimp production comes from Penaeus vannamei. So far, Penaeus vannamei has been developed in China for more than 20 years and has formed a huge industrial chain. However, in recent years, the disease of Penaeus vannamei has been endless. According to the survey data of the Global Aquaculture Alliance (Figure 1), diseases and aquaculture costs are the main difficulties and challenges facing global South American aquaculture. How to improve the survival rate of P. vannamei farming and reduce the cost of farming is a necessary way to improve the international competitiveness of P. vannamei farming in China!
With the world's leading bio-fermentation technology, the Biochemical Business Unit of the Xijie Group has uniquely developed and produced a single Bacillus aerobic fermented protein powder, Soytide, at home and even globally. Suyopeptide is an aerobic solid-state fermented soybean meal product of Bacillus. Bacillus grows fast and has strong protease secretion ability. It is the preferred strain for soybean meal fermentation. Bacillus fermented products have complete degradation of anti-nutritional factors (Figure 2) and crude protein The characteristics of high, high digestion and absorption rate, and good water stability (Figure 3). Suyide contains 107 high-temperature-resistant bacillus, and there are still live bacteria after high-temperature granulation or even puffing (Figure 4). After feeding, aquatic animals improve their intestinal health, enhance immunity, improve water quality and reduce shrimp mortality . Through the practice in the culture of Penaeus vannamei, we found that Suyopeptide can replace fishmeal in shrimp culture and reduce the cost of culture; it has significant effects in enhancing shrimp intestinal health, reducing mortality and improving water quality.
Study on the feasibility of substituting fast peptide for fish meal
1. Experimental design
Choose 480 healthy Penaeus vannamei juveniles, initial weight 0.5g, 3 repeats per feed treatment, 40 shrimps per repeat. The diet of juvenile shrimp includes a control group (fish meal group) and three test groups (speed peptide, fast peptide (sterilized) and fermented soybean meal D instead of part of the fish meal group). The dietary formula is shown in Table 1. The experiment uses full feeding, feeding 4 times a day for 8 weeks. The test environment is 27.0 ± 1 ℃, equipped with a seawater circulation device (salinity 33ppt).

2.1 Effect of Suyopeptide on Growth Performance of Juvenile Shrimp
Regardless of whether it is sterilized or not, Su Yi peptide has successfully replaced 9 points of fish meal. The non-sterile Su Yi peptide group also significantly increased the weight gain and specific growth rate of Penaeus vannamei (P <0.05), After sterilization, the fast peptide still improved the production performance of Penaeus vannamei to a certain extent. The results showed that the improvement of the production performance of Litopenaeus vannamei benefited from the degradation of probiotics and product antigens.
2.2 Effect of Su Yi peptide on nonspecific immunity of juvenile shrimp
There was no significant difference in the inhibition rate of superoxide dismutase between the groups (P> 0.05), but the lysozyme activity of the juvenile shrimp in the fast benefit peptide group was significantly higher than that in the fish meal and fermented soybean meal group D (P <0.05). Among them, the lysozyme activity of the Su Yi peptide (sterilized) group was significantly higher than that of the fermented soybean meal D group, and it was also improved to a certain extent compared with the fish meal group (Figure 6).
Study peptides applied to the survival rate and water quality improvement of Penaeus vannamei
1. Experimental design
Select 120 healthy Penaeus vannamei, the initial weight is 4.08 + 0.12g, 3 replicates in each group, 10 juvenile shrimps in each replicate. The diets were divided into control group, control & probiotic group (control group (+)), fish meal replacement group (speed peptide group), fish meal replacement & probiotic group (speed peptide (+)), in which probiotics were derived from A commercial brand B (Table 2). The test uses full feeding, feeding 4 times a day, the test period is 4 weeks. The test environment is 27.0 ± 2 ℃, equipped with sea water circulation device (salinity 33ppt).
