Whether the nine section shrimp is wild or farmed, and whether the Jiwei shrimp is a breeding method

Both wild and farmed are available.

Shrimp is rich in nutrients, its meat is soft, easy to digest, and it is an excellent food for people who are weak and need to recuperate after illness; Shrimp is rich in magnesium, which protects the cardiovascular system and reduces blood cholesterol.

content, prevent arteriosclerosis, and at the same time dilate coronary arteries, which is beneficial to prevent hypertension and myocardial infarction.

Shrimp meat also has tonifying the kidney and strengthening yang, promoting milk and anti-poison, nourishing blood and solidifying essence, dissolving stasis and detoxifying, nourishing qi and nourishing yang, channeling and relieving pain, appetizing and phlegm.

Both wild and farmed.

Jiujie shrimp is mostly found in the southern region of Fujian, especially one of the seafood loved by Cantonese people. Its real body is a tabby shrimp. Legend has it that the nine-section shrimp is very festive.

Eating nine-section shrimp Cantonese people depends on the freedom of the shrimp and the place where they live. The degree of freedom is to see whether the shrimp is wild or not, and the taste is wild. Wild shrimp have a dark red pattern, while raised shrimp have a much lighter color.

Jiujie shrimp is mostly found in the southern region of Fujian, especially one of the seafood loved by Cantonese people. Its real body is a tabby shrimp. Legend has it that the nine-section shrimp is very festive.

After being put on the water, it will spit out secretions, causing itself to die, so that those who like to try new things will not be touched, and it has the heroic and heroic spirit of "rather for broken jade than for the whole tile". Therefore, shrimp farmers must change the water frequently to flush away secretions to prevent it from "committing suicide". And the nine-section shrimp, which could not "commit suicide", finally died of "homicide" when it was grandly listed in midsummer and August.

Most of the people who killed it were Cantonese people who admired "the people take food as the sky". In the Guangdong area, the most common is the brown tabby shrimp, which is called ghost shrimp by Cantonese people.

Jiwei shrimp is a type of shrimp farming.

In the coastal areas of southern China, people will build embankments around the fields to prevent flooding. Some shrimp prefer the low salinity of shallow waters, and will take advantage of the high tide to climb these embankments to ingest food, so they become "shrimp in the enclosure".

Although the shrimp caught with the base can be called the base shrimp, the base shrimp on the market at present is mainly based on the new shrimp with the knife forehead, also called sand shrimp or mud shrimp. In appearance, this type of shrimp is earthy yellow to tan in color, and belongs to the shallow sea shrimp near the shore, and there will be brownish stripes on the surface.

Main Differences Between Jiwei Shrimp, Litopenaeus vannamei and Prawns:

1. Appearance difference: there are brownish stripes on the surface of Jiwei shrimp, and there are patterns on the shrimp tail, and there are stripes on the shrimp body after cooking; The color of the shrimp body of Penaeus vannamei shrimp is transparent and clean, and there is no obvious pattern on the surface; The appearance of the prawn is somewhat similar to that of the white prawn;

2. Difference in size: the prawns are the largest, the base shrimp is the smallest, and the white shrimp is in between;

3. **Difference: Litopenaeus vannamei shrimp is the most common and cheapest, Jiwei shrimp and prawns are more expensive, if it is a sea-caught prawn, they are basically sold according to only.

A: Yes. At present, there are more wild and farmed shrimp on the market, and it should be South American white shrimpMonodon shrimpMost of them, and the farmed shrimp to freshwater aquaculture, or freshwater seawater mixed aquaculture, or pure seawater aquaculture, due to the influence of the salinity of the aquaculture water, there will be a big difference in appearance, the general seawater aquaculture is closer to the quality of wild shrimp.

For example, the shell of wild South American white shrimp is generally worse than that of farmed shrimp, the shell is thicker, the color is lighter than that of shrimp, the shrimp is longer, and the wild meat is solid and sweet in taste. If boiled with boiling water, due to the lack of moisture in the shell and the high salt content, the shell appears drier, and even dehydrated and whitish, and brackish water farmed shrimp generally does not have this phenomenon.

In the southern coastal areas of China, in order to prevent flooding, the local people fence the coast with a "foundation fence"; One species of sea shrimp, "hemp shrimp", likes to hide itself in the mud and sand of shallow waters at high tide, and fishermen have built a base fence to catch hemp shrimp after discovering this characteristic of hemp shrimp; Later, fishermen began to cultivate this shrimp in seawater by the sea, and named it "Jiwei shrimp".

Unlike wild seafood, Jiwei shrimp is a type of marine farmed shrimp. Jiwei shrimp is also a seafood product, which is different from general seafood in that most of it is artificially farmed; Seafood is often grown naturally and harvested by hand.

The difference between wild shrimp and farmed shrimp is manifested in the shrimp gun, shrimp shell and meat quality, wild shrimp need to prey on their own, so their shrimp guns are short and thick, the shrimp shell is thick and hard, and the flesh is elastic, while the farmed shrimp do not need to predate on their own, the shrimp gun does not play the role of predation and thus grows longer and thin, the shrimp shell is thinner, and the meat is not elastic.

1. Shrimp guns are different

The difference between wild shrimp and farmed shrimp is manifested in the shrimp gun, in which wild shrimp grow in the natural environment and need to prey on their own to survive, so their shrimp guns are short and stout, which can be used as **, while farmed shrimp do not need to hunt on their own, so their shrimp guns are longer and thin.

2. The shrimp shell is different

The difference between wild shrimp and farmed shrimp is also manifested in the shrimp shell, in which wild shrimp will grow hard and thick shrimp shells in the process of natural growth, in order to protect themselves, to avoid injury, and the environment in which farmed shrimp grow, there is no enemy, and the competition is small, so its shrimp shells are thinner.

3. The meat quality is different

The difference between farmed shrimp and wild shrimp is manifested in the meat quality, in which wild shrimp will continue to move and look for food in the process of growth, so its meat quality is elastic and has a fresh taste, while farmed shrimp does not need to move to find food, and its meat is relatively soft.

4. The shrimp line is different

The difference between farmed shrimp and wild shrimp is also manifested in the shrimp line, in which the farmed shrimp eats artificial feed, there will be more impurities in the shrimp line, and the color is darker, while the wild shrimp eats natural feed, and the impurities present in the shrimp line are less and the color is lighter. Moreover, there is shrimp paste on the head of wild shrimp, but there is no farmed shrimp.

There are some differences between the farmed nine-section shrimp and the nine-section shrimp of the wild year, which are mainly manifested in the following aspects:

The growing environment is different: the farmed nine-node shrimp grows in artificial facilities, usually aquariums, plastic ponds, etc., and the growth environment is artificially controlled. Whereas, the wild nine-knot shrimp grows in the natural environment, usually in freshwater waters such as rivers and lakes.

The feeding method is different: the farmed nine-node shrimp are usually artificially fed, mainly artificial feed or other food, and the growth rate is relatively fast. On the other hand, the wild nine-knot shrimp is mainly based on natural food, such as small aquatic animals and plants, and the growth rate is slower.

Different taste and texture: Due to the different growth environment and feeding methods of farmed shrimp, the nutrients, texture and taste contained in the body are slightly different from those of wild shrimp.

**Different: The amount of hail produced by the farmed nine-section shrimp is relatively large and the market is relatively low. However, the production of wild nine-section shrimp is small, and it is affected by environmental pollution and other factors, and the production is relatively high.

It is important to note that whether you are farming or wild shrimp, you need to choose a fresh, odorless product and handle the ingredients according to the correct cooking method to ensure that it is safe and nutritious.

Freshwater aquaculture is not recommended for the nine-node shrimp (Penaeus monodon).

Breeding pond treatment: 70-100kg of quicklime is used per mu of pond to sprinkle at the bottom of the pond, and then water is added 15 days before the seedlings are released, tea meal and chlorine-containing disinfectant are used for treatment, and wastewater is carried out after 2 days. Water Quality Requirements:

The water level is 80-100cm, the transparency is between 20-30cm, and the salinity is between 25-35, and it shall not be less than 18. Can nine-node shrimp be cultivated in freshwater, and it is not recommended to use freshwater aquaculture for nine-node shrimp (Penaeus monodon).

The breeding technology is as follows: the aquaculture pond is treated with seawater to flush the aquaculture pond, the silt in the pond is washed clean, and then the water in the aquaculture pond is emptied and exposed to the sun. If the pond cannot be cleared, use 70-100kg of quicklime per mu of pond to evenly sprinkle on the bottom of the pond.

About 15 days before the seedling, add 80-100cm of water, and then use tea meal to kill the trash fish in the breeding pond, and then use chlorine-containing disinfectant to disinfect (effective chlorine concentration 5-10mg l). After 2 days, fertilize and water to cultivate the base bait. The water quality requires the water level to be about 80-100cm, the transparency to be about 20-30cm, and the water color to be yellow-green.

pH is controlled between, salinity is controlled between 25-35, not less than 18, and the salinity difference with the nursery pond should not exceed 5. The water temperature is controlled at around 24-28.

Stocking is about 4000-6000 per mu, and if the breeding conditions are good, it can be increased to more than 10000. Shrimp seedlings are required to be more than 1cm in length, vigorous, neat in size, robust individuals, no damage to the appearance, no parasitism, 7-9 o'clock in the morning or evening, in the upwind of the shrimp pond seedlings.

It can be raised, but it is difficult to get.

As long as you can eat and sell for money, there will be people who breed it!
