How much is the market price of mantis shrimp in Wuhan? Is it the same as rich shrimp? Can I breed it artificially? How can you not die?

Skinned shrimp, also known as pipa shrimp, mantis shrimp, shrimp rake, shrimp male camel, crayfish, mantis shrimp, shrimp cricket, distributed in coastal shallow water sediment or reef cracks. How much is the market price of mantis shrimp in Wuhan? Is it the same as rich shrimp? Can I breed it artificially? How can you not die? It is learned from the Wuhan Farmers' Market that the retail price of mantis shrimp has dropped from 50 to 60 yuan per 500g to 110kg (1500 grams), equivalent to about 36.7yuan per 500g.

Is mantis shrimp the same as rich shrimp?

Fugui shrimp, commonly known as "urine-dependent shrimp", "mantis shrimp", "crawling shrimp", "Oratosquilla" and so on, belong to the phylum Arthropoda, crustacea, Oratopoda, Oratosquilla species. Is a common marine economic animal, for the bottom sacrifice burrowing shrimp, living in shallow tides and deep-sea sediment or coral reefs, day and night. There are more than 60 families. The distribution range is very wide, Guangdong has Thailand imported shrimp cricket, its body length is up to 30 cm, domestic shrimp carp is about 10 to 15 cm long and weighs 50 to 100 grams. Oratosquilla is a coastal variety with low price. It is a kind of seafood food with rich nutrition and fresh meat. It is the same as mantis shrimp.

Can mantis shrimp be farmed artificially?

Mantis shrimp can be farmed artificially. Mantis shrimp lives in many caves, belonging to marine life, often digging holes at the bottom of sand or sediment in shallow sea, mostly in the shape of "U". Stomatopods are carnivorous and prey on small invertebrates. Pay attention to the temperature, salinity, times of changing water and so on.

Culture methods:

1. Mantis shrimp, who has been mated in artificial culture or natural sea area, can be selected.

2. When cultivating mantis shrimp, we should pay special attention to the temperature difference. Generally speaking, when cultivating, the water temperature is controlled at 20-30 ℃. Water temperature is the inhibitory factor of gonadal development of skinned shrimps. In the range of suitable temperature, the higher the water temperature, the faster the development. If the temperature is too high in summer, it can increase the water level and prevent the water temperature from being too high to affect mantis shrimp's egg holding, hatching and even death. At the water temperature of 25-30 ℃, it takes 7-15 days for eggs to be fertilized and hatched.

3. Mantis shrimp can feed on fish, shrimp and shellfish, but it is better for fresh small shellfish to avoid polluting the water quality. Small pieces of bait are better, should be scattered evenly in order to ingest food, and the well can increase the consumption of bait by half and reduce the killing of each other due to grabbing food. According to mantis shrimp's characteristics of sleeping during the day and going out at night, bait can be given once a day in the evening, and the amount of bait is 5% to 20% of mantis shrimp's weight, and increases or decreases appropriately with mantis shrimp's egg holding, water temperature, weather conditions, bait types and quality conditions.

4. During the cultivation period, pond patrol is a necessary work to check the influent and drainage, mantis shrimp's activities and feeding, water quality, especially the discharge of larvae. Once it is found that mantis shrimp discharged false flea larvae, that is, the larvae were collected into the seedling pond to raise seedlings.

How can mantis shrimp not die?

1. Suitable conditions for shrimp:

The water temperature is 18-19 ℃ and the salinity is 16-18%. Shrimp requires clean water quality, so the water must be recycled or changed at least once a day.

2. Two points must be paid attention to in the process of blending sea water:

First, tap water needs to be kept for more than half a day before it can be used (and the precipitation below should be removed). Chemical dechlorination can be used. The commonly used dechlorination drug is sodium thiosulfate, which is generally 10 kg of tap water and 1 g of sodium thiosulfate. Second, sea water essence (quality is very important) is a special salt for feeding seafood, so it can not be replaced by ordinary salt.

3. Oxygenation:

Feeding seafood does not mean that the more oxygen, the better. If too much oxygen is filled, the gas emitted by the oxygen pump will wash the seafood to death. More water and less shrimp can not be oxygenated or just open the cycle is enough.

4. Adjust the pH of the water:

The pH of water is closely related to the survival of all kinds of seafood. Sodium dihydrogen phosphate and sodium bicarbonate are commonly used to regulate the pH of water quality. Before use, the two drugs should be dissolved in pure water and mixed into a solution of 1Rau 100. Sodium phosphate can increase the acidity of large water; sodium bicarbonate can increase the alkalinity of large water. When in use, the prepared solution can be added to the water drop by drop, fully stirred, and continuously tested with PH paper, until the pH of the water meets the requirements, the change of the pH of the water should be controlled in the range of ±0.1.
