How to breed shrimp and how to breed shrimp?

1. Hong Kong maintenance method.

Hong Kong culture is the traditional way of breeding in China, the breeding area ranges from more than ten hectares to hundreds of hectares, generally according to the natural topography of the intertidal zone of the sea area to build a dam enclosure, and the breeding equipment is simple.

In aquaculture, it generally relies on natural seedlings, and can also be put into industrial seedlings, but it does not fertilize or feed, and completely relies on natural productivity to provide products.

Its product categories include fish, crabs, shrimps, shellfish, etc., and the types of artificial seedlings put into the single species can also produce more than ten kilograms per mu, and the comprehensive (mu) benefits can reach hundreds of yuan.

Hong Kong culture is a breeding method that is worth advocating and developing. Especially in recent years, there has been a serious outbreak of shrimp disease and serious eutrophication in the coastal waters, which shows the great advantages of this method.

2. Semi-intensive farming.

It is developed on the basis of Hong Kong maintenance. That is, to build an ecological environment suitable for the survival and growth of shrimp, so that shrimp can obtain higher yields.

The establishment of the ecological environment includes artificial control of water temperature, salinity, transparency, substrate, water depth and predator organisms, so that it is in the most suitable environment for shrimp needs, and then through reasonable seedling, supplemented by feeding, higher yields can be obtained.

Due to the less bait and less organic matter in shrimp farming wastewater, this method has little adverse impact on the environment and can achieve high economic benefits. Therefore, it is also a breeding method worth promoting.

3. Intensive cultivation method.

This method is generally used in smaller ponds. Shrimp farming in this way requires good pond conditions, high water exchange rate, aeration equipment, complete facilities, artificial high-quality bait, and high seedling volume per unit area.

As long as the environmental control is reasonable and the feeding is reasonable, a higher yield can generally be obtained. The yield per mu of intensive farming in China is up to 1050 kg, and the benefits are also very high.

However, this method requires a lot of funds, a large investment, a large risk, a high bait coefficient, and a serious environmental pollution. Therefore, from the perspective of long-term benefits, large-scale promotion should not be advocated.

4. Polyculture.

Polyculture refers to the stocking of other fish, shellfish, algae, crabs and other species while raising shrimp, and the aquaculture products include shrimp and polyculture species.

In principle, the selection of polyculture species is not predatory to shrimp, does not affect the survival and growth of shrimp, does not compete with shrimp for food or has weak ability to compete for food, preferably omnivorous or scavenging, and can use shrimp residues.

Through polyculture, it can improve the utilization rate of bait, reduce the organic pollution of shrimp farming wastewater, improve production and increase economic benefits, and also reduce the risk of monoculture shrimp disease and extinction.

5. Other ways.

There are also a variety of breeding methods, such as intensive shrimp farming, net enclosure shrimp farming, cage shrimp farming, etc. These breeding methods are rarely used in China.

1. Port maintenance modePort culture is a traditional Chinese cultural model, with a cultural area ranging from more than ten hectares to several hundred hectares. Generally, according to the natural topography of the intertidal zone of the sea area, it is surrounded by a dam, and the breeding equipment is simple. In aquaculture, it is generally natural to accept seedlings, and workers can also be put in, but no fertilizer, no bait, and the products are completely provided by natural productivity.

Its products include fish, crabs, shrimps, shellfish, etc. Artificially raised varieties can also yield more than 10 kilograms per mu, and the comprehensive benefits can reach hundreds of yuan. Port culture is a cultural way worth advocating and developing.

In recent years, in particular, severe outbreaks of shrimp disease and severe eutrophication in coastal waters have shown the great advantages of this approach. 2. The semi-intensive culture method is developed on the basis of port aquaculture. That is, to build an ecological environment suitable for the survival and growth of shrimp, so that shrimp can obtain higher yield per unit area.

The establishment of the ecological environment includes artificial control of water temperature, salinity, transparency, substrate, water depth, and pests, so that it is in the most suitable environment required by shrimp. This method can achieve high economic benefits due to less bait and less organic matter in shrimp wastewater, and less adverse impact on the environment. Therefore, it is also a breeding method worth promoting.

3. Intensive cultivation method: This breeding mode is generally adopted in small ponds. In this way, shrimp farming needs good pond conditions, high water exchange rate, aerobic equipment and facilities, mainly artificial high-quality bait, high seedlings per unit area, as long as the environment is reasonably controlled, reasonable feeding, generally can obtain higher yield. The yield per mu of domestic intensive cultivation is as high as 1050 catties, and the benefits are also very high.

But this method requires a lot of money, large investment, high risk, high bait coefficient, and serious environmental pollution. Therefore, in the long-term interests, large-scale promotion should not be promoted. 4. Polyculture refers to other species of fish, shellfish, algae, crabs, etc.

It is reared at the same time as shrimp farming, and the cultured products include shrimp and polyculture species. In principle, the selection of polyculture species is harmless to shrimp, does not affect the survival and growth of shrimp, does not compete with shrimp for food or has weak ability to compete for food, and it is best to be omnivorous or scavenging, and shrimp residues can be used. Through polyculture, we can improve the utilization rate of bait, reduce the organic pollution of shrimp wastewater, increase yield, increase economic benefits, and reduce the risk of disease and failure of monoculture shrimp.

5 There are many other farming methods in other ways, such as intensive shrimp farming, net enclosure shrimp farming, cage shrimp farming, etc. These farming methods are rarely used in China.

<> prawns can be farmed. The Ministry of Agriculture issued the NY T5059-2001 pollution-free food shrimp breeding technical specification stipulates shrimp seed cultivation, cultivation and disease control technology, which is applicable to China's main farmed shrimp.

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.

Shrimp Technical Points:

1.Pond disinfection

1) The pool is required to be flat, no leakage, moderate size, suitable water depth (soil pond rice, high pond rice), and equipped with an aerator.

2) After the last crop breeding harvest, the film pond should be washed, the soil pond or sand pond should be sunburned, and the aging pond should be sprinkled with quicklime and then exposed, and the amount of quicklime is 80 100 kg mu.

3) The process of clearing and disinfecting is to remove trash fish, miscellaneous shrimp and pathogens such as parasites, bacteria, and viruses. You can choose the drug according to your needs, and pay attention to the safety of the drug.

2.Influent treatment

When the shrimp pond is flooded, it is filtered and precipitated if the conditions are not enough, and the 80 100 mesh sieve silk net is required to reduce the entry of trash fish, miscellaneous shrimp and their eggs into the breeding pond. A water intake to a depth of 1 meter can make the early stage of breeding without adding water, reducing the exchange with the water source. Choose low-toxicity and high-efficiency water disinfectants (such as chlorine dioxide) to carry out water disinfection reasonably, so as to not only effectively disinfect and sterilize, but also have little impact on planktonic single-celled algae.

3.Water quality culture

Ponds (fertilizer ponds) that have been cultivated for many years without dredging should be applied with inorganic compound fertilizers, such as the "single-celled algae auxin" developed by the South China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences, with an application rate of 1 2 kg (mu · m). Newly developed ponds, filmed ponds, ponds with sandy bottoms and ponds with thorough dredging should be applied with organic and inorganic compound fertilizers. You can also carry out scientific fertilization by yourself, and the principles of mastery are:

The fertilizer element is soluble, the N-P ratio is greater than 10 1, and the other elements are appropriate.

Generally speaking, 5 7 days before stocking shrimp seedlings fertilization, 5 7 days after seedlings can be applied once, and later can play a role in the degradation and transformation of organic matter by beneficial microorganisms, so as to increase the fertility of aquaculture water.

4.Shrimp fry stocking

Shrimp seedlings are selected to be robust, vigorous, uniform in size, clean and intact on the body surface.

<> shrimp farming needs to pay attention to the construction of shrimp ponds, the regulation of water quality, the feeding of bait and daily maintenance. The shrimp pond should dig a deep pit in the low beach area on the edge of the sea fiber, disinfect it with quicklime and inject seawater to keep the water clean, properly put some plankton, and the bait is mainly based on various small organisms, pay attention to regular disinfection.

1. Build a shrimp pond.

If you want to breed prawns, you must first dig a shrimp pond with a depth of about 150 cm and the deepest place can reach about 200 cm in the low beach area by the sea, and after excavation, pat the wall of the compacted pit, pour water mixed with quicklime for disinfection and sterilization, and then pour it into seawater.

2. Regulate water quality.

The seawater in the shrimp pond must be clean enough first, there can be no large number of dead animal and plant remains, at least it must be relatively clear, and then it needs to be artificially adjusted, put in some marine plants and small plankton to maintain the ecological balance in the shrimp pond, and then you can inject the purchased shrimp seedlings into the shrimp pond.

3. Feed the bait.

Shrimp is omnivorous, wild shrimp diet is very wide, involving most of the small animals and plants, including plankton, carrion and microorganisms, etc., in the daily breeding is mainly to small shellfish, worms, plant feast of the detritus, newborn shrimp eat very little, generally can only eat some plankton.

4. Daily maintenance.

The vitality of the shrimp is still relatively tenacious, the general feeding food does not need a lot, relying on the natural adjustment ability of the shrimp pond Qingzhuyin can also live well on the shrimp, but after all, the shrimp pond is a relatively closed environment, the need to regularly replace the water body, the use of aerators to inject oxygen, adjust the pH value, etc., all need to be adjusted according to the actual situation.
