Shrimp farming is extensive, what are the environmental conditions for shrimp farming?

It is necessary to regularly change the bottom, detoxify and adjust the water. It is mainly based on biological modification, and there are many benefits of cultivating bacteria and algae. Chemically modified detoxification products are used once at a time to prevent excessive accumulation of toxic substances in the water, beyond the ability of bacteria and algae to regulate.

For the selection of shrimp seedlings, we should choose shrimp seedlings with strong physique, complete appendages, and no disease or injury. The feeding of bait should be as comprehensive as possible to ensure the comprehensiveness of nutrition and prevent its slow growth due to single nutrition. Be sure to disinfect on time, change water regularly, and do a good job in epidemic prevention of various diseases on a regular basis.

The choice of shrimp seedlings, the advantage of choosing soil pond desalination seedlings is that the disease resistance is higher, but the breeding cycle is long, the advantage of choosing a generation of desalination seedlings is that the growth rate is fast, the shrimp cycle is short, and the size of the shrimp is large, but the requirements for the breeding environment are extremely high, and the disease resistance is low, it is recommended to adapt measures to local conditions, feed feeding, crayfish is omnivorous, aquatic weeds, insects, animal carcasses, and so on It will eat, artificial breeding crayfish is based on synthetic feed, generally twice a day, crayfish have a higher demand for calcium, If you can, you can feed some snails, <>

The most important thing is the water quality, as for the temperature control at about 26, it is the best, but if you don't raise crystal shrimp, in fact, the temperature has little effect, as long as it doesn't reach 30 degrees, the shrimp is absolutely fine! The most important thing is the water quality! Shrimp are prone to nematodes is to strengthen the management of aquatic weeds and clean up the aquatic weeds in the pond in time.

Aquatic weeds are the key to the success of shrimp farming, but too many aquatic weeds, such as more than 40% of the pond, aquatic weeds are perishable, resulting in hypoxia at the bottom of the pond, affecting the life and growth of green shrimp, so it is necessary to control the total amount of aquatic weeds in the shrimp pond at about 40%.

Take care to control the salinity of the shrimp pond. We must first take care of the injury, we must pay attention to control the salinity of the shrimp pond, only the next time to control the assistance can the survival rate be improved, in order to improve the healthy growth rate of shrimp. Shrimp farming is mainly oxygen, there is no oxygen underwater aquatic plants can not grow, there is to pay attention to the water quality feed to observe the growth of shrimp, whether there are diseases, read more shrimp books, communicate with other farmers to learn, and slowly accumulate experience.

1.There should be water sources around, and drainage and irrigation are better. 2.

The water quality must be kept between pH and not higher than the frequent injection of new water sources, and the transparency of the water quality should be maintained at about 30 to 40 cm. Regularly sprinkle quicklime into the pond to adjust the water quality. 4.

If the temperature of juvenile shrimp is suitable and the feed is sufficient, it can be used for 60 to 90 days.

The most basic condition is to have paddy fields or ponds, and secondly, there is a certain economic strength and anti-risk ability, no matter what is cultivated, there are risks.

The suitable water temperature is 22-32 degrees, the pH value is in the range, the shrimp pond can not accumulate water, leakage, and the water quality must have good transparency.

The condition is that you must choose some water resources with relatively clear water quality, there must be oxygen machines around, there must be some Xinbi feed, and there must be aquatic plants in Shiver, and the water temperature must be controlled at 8.

First of all, you should choose a relatively strong physique, no disease and no injury of the shrimp seedlings, and then when feeding, which round, should ensure that the nutrition is comprehensive, should be regularly changed water, to ensure that the shrimp pond is clean, and the trembling can prevent the diseases of each Li Dong letter.

It is best to be able to breed at the seaside should introduce some seawater, model friends should be accompanied by some seaweed and silt when breeding, the temperature should be kept at 20 degrees, but not too low, should be cleaned regularly, should be regularly disinfected.

Keeping the water temperature above 20, putting some salt in the water, pouring in fish feed, preparing fresh water, and cleaning the pond of silt, these are all breeding conditions.

Water quality is extremely important for Penaeus monodon. Farmers do not pay attention to water quality, resulting in a large number of shrimp seedlings dying. Water quality is closely related to the molting and habitat of Penaeus monodon.

When the water-soluble oxygen is abundant, Penaeus monodon inhabits quickly and is not suitable for perching. In the high temperature season, the breeding water is easy to sour and smelly, and it needs to be replaced every two to three days. In addition, as Penaeus monodon grows, its size decreases.

Therefore, it is necessary to continuously deepen the water level and obtain sufficient living space. When the seedlings are planted, the water level is about 5 to 10 centimeters, and eventually the water level will rise to about 10 to 30 centimeters.

The water temperature of the environment in which Penaeus monodon grows is also important. Penaeus monodon is suitable for living in water temperatures of 18-30 degrees, so it is usually stocked in late May, when the temperature is relatively stable and suitable for seeding. In order to ensure the survival rate of shrimp seedlings, desalination needs to be carried out one week after the seedlings are released.

In addition, after putting them in salt water for a week, they can be moved into the breeding pond and discarded some things that need to be raised step by step, in addition to watering and feeding, can also be carried out. Shrimp seedlings into the pond is daily management, especially water quality, feeding, disease prevention and control management. Water quality regulation is extremely important.

When raising shrimp seedlings for about 10 days, water should be gradually added and quicklime or bleaching powder should be sprayed to improve water quality and sterilization. When the water temperature reaches 24 degrees to 30 degrees, the food intake of Penaeus monodon shrimp will decrease, which is also the period of its rapid habitat, and it is necessary to reduce the food intake to ensure food**; Disease management is mostly based on this prevention. Regular spraying of quicklime mold at each time slot can also replenish calcium and enhance molting habitat.

Although Penaeus monodon has strong disease resistance and growth ability, it should be carefully managed and paid attention to its activities in the breeding process to ensure high yield and its own economic benefits. Regularly add 10-20 cm of fresh water to the pond, the fresh water source must be strictly filtered, add a considerable amount of water rich in dissolved oxygen to the rivers and lakes, and install an aerator to increase oxygen; Prepare enough oxygenator for emergency use.

Put "white music" + "polyhedron xel" every half a month. In the morning, when the dissolved oxygen content of the shrimp pond is abundant, add water to fully dissolve it, and then splash the whole pond to prevent the water body from being too thick and the algae from dying when the wind direction changes, so as to achieve the purpose of clarifying the water quality and increasing the transparency of the pool water. Enhance the physique of shrimp, regularly take "Qi + Saiwei" (a group of 300 kg) to enhance the resistance of shrimp, increase the muscle firmness of shrimp, and reduce the phenomenon that the white body of shrimp does not disappear for a long time.

In view of the death of algae and toxic and harmful substances, "Baile" and "nactogenin" are poured every 10 days to achieve the dual solution of toxins and organisms in the water. Flexible feedingAdhere to frequent feeding, less feeding, do not feed when dissolved oxygen is less than 4mg l, feed more when the water quality is good, feed less when the water quality is not good, feed less or no when the north wind rises and the temperature falls, and feed less when a large number of shrimp are shelled.

Water temperature. The adaptation range of Jiwei shrimp to water temperature is very wide, and it is distributed in the sea area 8 29, and the water temperature of aquaculture is 18 25. Food. Jiwei shrimp is omnivorous and partial zoophagous, mainly preying on benthic organisms, and also feeds on benthic plankton and swimming organisms.

It is necessary to maintain the hygiene of the environment, and to have sufficient water sources, and should also change the water in time, ventilate in time, etc., which is the basic requirement of shrimp farming, and it is also very reasonable.

There must be a suitable water temperature, and the salt content in the water must be very moderate, when feeding, the choice of food is also very important, and you can put some aquatic plants in the water, to choose a very good site.

Shrimp is one of the important economic species of aquaculture at present, which is mainly divided into two types: freshwater shrimp and marine shrimp. Let me introduce the conditions required for shrimp farming.

1.Water quality conditions: The water quality conditions suitable for shrimp growth are between pH value, temperature between 28 30, hardness of 60 150, and proper water flow and oxygen.

2.Water conditions: The water should be kept fresh, pollution-free and the number of microorganisms should be low. There are cisterns to prepare water.

3.Base conditions: The terrain of the exacerbated jujube shrimp pond should be gentle, the water source should be sufficient, the ground drainage should be good, and the green belt around the farm should be built to avoid pollution.

4.Feed conditions: There are many kinds of feed for shrimp, and the feed suitable for different growth stages and feeding methods should be separated.

5.Equipment conditions: The equipment used in shrimp farming includes mechanical and electrical equipment, pond covers, reticulated shells, pumps, filters, oxygen equipment, etc.

In general, the key to shrimp farming is scientific breeding technology and management.

The pH value is measured from 6:30 to 7 o'clock in the morning, and if the pH value is lower in the morning, lime should be applied to increase it, and fertilization should be considered. Ammonia nitrogen and nitrite are measured every 3 days. Observe the shrimp to observe the food table, see if the shrimp in the food table is healthy (body color, tentacles, swimming feet, gills, liver and pancreas, stomach, intestines, feces, etc.), whether there are shrimp shells, if there are shrimp shells, the shrimp may lose shells more at night, and calcium supplementation should be strengthened.

Patrol the pond for observation.

Penaeus vannamei (scientific name Oriental prawn, also known as Chinese prawn, Litopenaeus vannamei and Litopenaeus monodon) is a shrimp of the phylum Arthropoda, Molluscs, Decapodae, Shrimpidae, and Shrimp of the genus. Shrimp is a large individual, commonly known as prawns. Shrimp production is increasing rapidly through extensive commercial farming.

Whole prawns are cooked in braised sauce, deep-fried, and sweetly grilled.

Shrimp belongs to the phylum Arthropods, with Gill Subphylum, Crustacea, Mollusctuary, Decapod, Swimming, Shrimp Family, and Shrimp Genus. Chinese prawn is one of the main species of the shrimp genus, commonly known as "prawn". The body of the shrimp is long and slightly flattened, dioecious, the adult female shrimp is larger than the male shrimp, and the body color is also very 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.
