Indoor shrimp farming technology,? What conditions and technologies are needed for shrimp farming

Indoor shrimp farming is **, this has been qualitative, due to the use of brine for farming, sewage and water treatment sludge to form land salinization, the environmental protection department is cracking down.

First of all, indoor shrimp farming is the earliest is to raise tropical shrimp such as shrimp, etc., this kind of shrimp has relatively high temperature requirements, the temperature in many places can not meet the requirements of breeding, or the breeding temperature is free in just a few months, the use of indoor farming, can completely adopt indoor temperature control, new technology of circulating aquaculture, improve the production of shrimp farming, shorten the shrimp breeding cycle, is not the first to be, but the investment is large, the technical requirements are high, and not the average person can master the use, the need to have professional and technical personnel, not only familiar with shrimp farming technology, It is also necessary to understand the temperature control, equipment management and other technologies of indoor shrimp farming, so it is necessary to go to a professional farm to learn, and our ordinary farmers are not competent.

The conditions and techniques required for shrimp farming are as follows:

1. It is very important to choose a location when raising shrimp, to choose a place where the surrounding water source is abundant, drainage and irrigation are better, you can build a pond in this place, or use rice fields to raise shrimp, shrimp is an omnivorous animal basically will not be picky, feeding commonly used meat feed snails, livestock scraps, etc., green feed vegetables, land grasses, etc., concentrate feed corn, wheat, grains, etc., when raising to remove enemies in time.

2. The water quality in the shrimp pond must be kept between the pH value, not higher, and it is necessary to inject new water sources frequently, and the transparency of the water quality in the shrimp pond should be kept at about 30-40 cm, and the quicklime solution should be poured into the pool regularly to adjust the water quality and prevent the occurrence of diseases.

3. In the process of shrimp farming, if the juvenile shrimp is at the right temperature and the feed is sufficient, it will grow to the size of the commercial ** in 60-90 days. Basically, shrimp are released in March, and they can be harvested around June.

How deep does the water need to be for shrimp farming.

1. Under normal circumstances, the suitable depth of the water for shrimp farming is meters, the suitable growth pH range of shrimp is more than 250mg l for shrimp farming, and the suitable total alkalinity is more than 80, if it is lower than 80 or higher than 400, certain protective measures should be taken.

2. In the process of shrimp farming, it will float out of the water to feed, if the water body is too deep, it is not conducive to shrimp foraging, and it is not good for shrimp growth, so in the process of shrimp farming, we must control the water quality and water level, which must be conducive to the growth of shrimp.

3. In the production of shrimp aquaculture, the quality of fertilizer water is generally measured by the color, transparency and freshness of the pool water, and the fertilizer water is also affected by environmental factors and nutrient factors.

1. Breeding density: the number is controlled at about 5-20, not too intensive. 2. Water quality management:

It is best to use clean river water and change the water every 5 days. 3. Regular calcium supplementation: sprinkle active calcium and vitamins for internal medication.

4. Feeding food: put clean fish, shrimp and animal offal, and generally feed them at night.

1. Breeding density

When breeding shrimp indoors, the density should be reasonably controlled, generally around 5-10, if the container is larger, the number can be maintained within 15-20, be careful not to put too many shrimp, otherwise the living space is too crowded, and it will die of lack of oxygen.

2. Water quality management:

When breeding shrimp indoors, clean pure water or river water should be used, and the tap water should be dried 2 days in advance, otherwise it will cause the shrimp seedlings to wilt and die, and the shrimp should be changed every 5 days to ensure that the water quality is clean to avoid breeding bacteria.

3. Regular calcium supplementation

If the shrimp wants to grow, it must be shelled, and the time from shelling to shelling again is about 12-24 hours, and its body length can be increased by 17%.

4. Feed food

In the process of daily shrimp farming, it is necessary to feed 1-2 times a day, generally at night, mainly fish, shrimp and animal offal, when feeding shrimp, the food should be cleaned so as not to pollute the water source.

Attention should be paid to the management of breeding density and water quality during indoor shrimp farming.

1. Breeding density

When cultivating shrimp indoors, the density should be reasonably controlled, generally around 5 to 10. If the container is large, keep the number to 15 to 20, and be careful not to put too many shrimp. Otherwise, the living space is too crowded and will die of lack of oxygen.

2. Water quality management:

When cultivating shrimp indoors, clean and pure water or river water should be used, and the tap water should be dried 2 days in advance, otherwise it will cause the shrimp seedlings to wilt and die. And change the water of the shrimp every 5 days to ensure that the water quality is clean to avoid breeding bacteria.

3. Regular calcium supplementation

If the shrimp wants to grow, it must shed its shell, and the time from shelling to shelling again is about 12 to 24 hours, and its body length can be increased by 17%. At this time, calcium should be added to the shrimp, calcium phosphate solution should be applied to the water, or soy milk milk should be poured in.

4. Feed food

In the process of daily shrimp farming, it is necessary to feed 1 to 2 times a day, generally at night, mainly fish, shrimp and animal offal. When feeding shrimp, wash the food to avoid contaminating the water source.

Tips for shrimp farming

1. Preparation.

Before raising shrimp, you need to choose a pond of the right size, clean it, and then filter the silt and dirty water at the bottom of the pond. Then clean up the debris, and finally expose the whole bottom of the pond to the sun for 2 to 3 days before starting to raise ants.

2. Select shrimp seedlings.

Before raising shrimp, it is necessary to choose high-quality shrimp species, preferably shrimp seedlings with a length of about centimeters, a relatively uniform body shape and a clean surface, and 4 to 6 spines on the forehead. The viability and disease resistance of this kind of shrimp fry are generally strong, which is conducive to improving the survival rate of shrimp seedlings.

3. Put shrimp seedlings.

Put shrimp seedlings in sunny weather is appropriate, the temperature should be above 25 degrees, before putting oxygen into the water, and add some sugars, and within 24 hours of putting to observe the survival of shrimp seedlings at all times. Replenish oxygen and bait in time to avoid mass death.

Techniques required for shrimp farming: 1. Pond treatment. One week before the pond is filled with water, the pond is evenly sprayed with 100-300 times of EM bacterial solution dilution and insect repellent made of EM bacterial solution instead of lime, etc., to disinfect and purify the pond.

2. Water purification. 3-10 days before stocking, splash the water surface with the diluent of the EM bacterial solution. Depending on the water quality, once every 15 days at the beginning, once a month thereafter, and where the water quality is poor, the splashing time should be appropriately shortened.

In order to spray evenly, dilute the bacterial solution before using it (the best spraying effect is in the evening or when it rains on a cloudy day). 3. Treatment of shrimp feed. Since the shrimp feed is granular, you can spray the bait with 200 times the dilution of EM bacterial solution, spray it with moisture, and feed it immediately to avoid scattering.

4. Treatment of organic fertilizer and manure. The organic fertilizer (grass liquid fertilizer) and manure to be put into the water body should be treated with EM bacteria solution first, and then fermented before being put into the water surface. Conditions for shrimp farming:

1. Water source. Equipped with deep water wells, groundwater is added regularly during the breeding process, which is safe and rich in mineral elements, and deep well water plays an important role in the alleviation of nitrite toxicity in the middle and late stages; In the process of breeding, try to avoid adding water from other rivers, especially in the stage when pesticides are frequently used in crops around the surrounding area. 2. Reservoir.

Qualified farmers can set aside 10-20% of the area as a reservoir, on the one hand, they can store the water of other rivers with good water quality, and on the other hand, they can pretreat the groundwater that does not meet the water quality standards. 3. Aeration facilities. The bottom aeration of the mu is matched with the waterwheel of the mu to improve the utilization rate of the waterwheel aerator (placed diagonally), fully stir the water body to divert water and increase oxygenation, and reduce the pollution of organic matter to the feeding area.

4. Heating facilities. Greenhouse seedlings early (mid-February began to put seedlings), after the seedlings will have the phenomenon of pouring spring cold, it is recommended to be equipped with a pot high laughing stove, compared with the heating rod boiler has the advantages of uniform heating, not affected by the voltage bucket, large hot water body, and better thermal insulation performance. If the temperature of the nursery pond is not guaranteed, the shrimp will not grow well even if the number of shrimp is not affected, and even early seeding will not necessarily be marketed in the morning.

At present, there is a trend of early season seedlings in greenhouses, and it is more important to equip boilers. 5. Specifications of seedling ponds (sheds in sheds). It is recommended to expand the area of the seedling pond in the shed and extend the temporary maintenance time of the shed in the shed, which can effectively improve the specifications of the enlarged pond and seize the market in the morning.

Water quality conditions: control the water depth at meters, the suitable hardness of the water body is more than 250mg l, and do not use tap water. Breeding Equipment:

Choose buckets, fish tanks, basins, etc., and lay a layer of sediment on the bottom. Stocking density: the general number of breeding is about 15.

Regular calcium supplementation: Put calcium phosphate, soy milk, etc. in the water to supplement calcium for shrimp.

1. Water quality conditions

When raising shrimp indoors, the water quality conditions are very important, under normal circumstances, the appropriate depth of the water for shrimp farming is meters, the pH value range is, the suitable hardness of the water body is more than 250mg l, try not to use tap water, clean river water is better.

2. Breeding equipment

When cultivating shrimp indoors, it is necessary to prepare a suitable container for it, you can choose buckets, fish tanks, basins, etc., and pay attention to disinfection before use, because shrimp like to drill holes, but also to lay a layer of sediment at the bottom, so as to facilitate hiding and perching.

3. Stocking density

During the indoor shrimp farming, the density should be reasonably controlled, if it is too much, it will die due to lack of oxygen, the general number of breeding is about 15, if the container is larger, the number can be maintained within 20.

4. Regular calcium supplementation

Shrimp will shed their shells during the growth process, it takes about 12-24 hours from shelling to growing shells again, at this stage, to provide rich calcium for shrimp, you can add calcium phosphate solution to water, or pour soy milk, milk and other substances.
