How to farm shrimp, how to farm shrimp How to farm shrimp

1. Breeding facilities. The pond area is 4-10 acres, with a depth of meters and a slope ratio of 1. The bottom of the pond is flat, the bottom quality is loam, the soil of the pond slope is hard, the pond has good water retention, and the water level is easy to regulate.

The water source is sufficient, and the water quality is pollution-free. In accordance with the pattern of high irrigation and low drainage, build drainage canals to achieve irrigation and drainage.

2. Preparation before stocking. Thoroughly clean and disinfect the pond 20-30 days before the stocking of shrimp seedlings, drain the pond water, remove excessive silt, renovate the pond ridge, and use 75 kg of quicklime per mu or bleaching powder, bleaching powder essence and other drugs to thoroughly clean and disinfect the pond.

3. Stocking of shrimp seedlings and shrimp seeds. Summer stocking pattern. The first batch of juvenile shrimp hatched in the year is mainly stocked, and the stocking time is in mid to late July, and the size of juvenile shrimp is more than centimeters. 30,000-40,000 tails per mu.

4. Scientific feeding. In the juvenile stage, they feed on rotifers, cladopods, copepods and larvae of aquatic insects, while in the adult stage, they feed on both animal and plant feeds. After the stocking of shrimp seedlings and shrimp seeds, fertilizer should be applied in a timely manner to fertilize the water quality.

In the rapid growth stage of crayfish from August to October, more bran, soybean cake and green feed should be fed, and animal feed should be appropriately fed.

5. Daily management. Establish a pool inspection system. Patrol the pool every day, and take countermeasures in time if abnormalities are found. Prevent escape and disease. During the flood season, inspections should be strengthened to prevent shrimp escape. Do a good job in disease prevention and control and enemy pest removal.

1. Pond disinfection: Before breeding, the pond should be desilted, sunburned, and poisoned.

2. Water quality improvement: the shrimp pond should be fertilized, which can save feed, increase dissolved oxygen, shade the bottom of the pond, and disinfect the water body, and be equipped with an aerator.

3. Shrimp seedlings: Shrimp seedlings should be desalined before they are put in, and when they are released, they should be carried out on the leeward side, that is, the wind blows from the back to prevent the shrimp seedlings from being blown to the shore by the wind.

4. Daily management: establish a pond inspection system, patrol the pond every day, strengthen inspection during the flood season, strictly prevent shrimp escape, and do a good job in disease prevention and enemy removal.

1. For the work of the pond, it is necessary to do three steps: dredging, drying the pond and poisoning the pond. Dredging is the removal of 15-20 cm of silt from the surface layer of the bottom of the pond. The pond can kill various pathogens and other predators, and improve the substrate environment. The purpose of the poison pond is to kill all kinds of predators.

2. The process of water quality is divided into inlet water and fertilizer water. The water inlet is to check the filter screen before the shrimp pond has been disinfected by the silver inspection to prevent copepods and small crustaceans with germs and viruses from entering the shrimp pond, so as to increase the chance of the shrimp being infected with the virus. Fertilizing water is for the cultivation of basic forage organisms, which is one of the most important aspects of healthy farming.

3. After the pond and water quality are good, you can stock shrimp, and what you need to discuss at this time is the stocking time and stocking density. The time of stocking should strive for the word "early". Regular stocking is usually in November or at the end of March of the following year.

The stocking density of sea shrimp is dominated by juvenile shrimp that are artificially bred in the current year. The stocking time is 7 September. 10,000 juvenile shrimp are stocked in each mu of shrimp farming ditch.

If there are more, there are more than 10,000 shrimp species of about 3 cm per mu of shrimp ditch!

Prepare containers: When raising shrimp at home, you can use discarded fish tanks, water basins, etc. Stocking shrimp fry:

After the water tank is cleaned, add an appropriate amount of water and put the shrimp seedlings in. Feeding food: mainly based on special feeds such as soybean cakes, snails, minced meat, etc., usually fed at night.

Water quality management: Change the water every 7-10 days or so.

1. Prepare the container

When raising shrimp at home, you can use discarded fish tanks, water basins and other containers, if you use water basins, the basin body can not be less than 20 cm, so as not to escape the shrimp, but it is best to use fish tanks to breed, large area, easy to manage.

2. Stocking shrimp seedlings

After the container is ready, add an appropriate amount of river water, and then put the bag containing the shrimp into the water, wait until the water temperature in the bag is not much different from the water temperature in the tank, prick a few small holes in the bag, and after 3-4 hours, open the mouth of the bag and let the shrimp swim out on their own.

3. Feed food

In the process of breeding shrimp, we should feed food 2-3 times a day, mainly based on special feed such as soybean cake, snail lion, minced meat, etc., and you can also choose an appropriate amount of algae and spinach.

4. Water quality management

When raising shrimp at home, we should pay attention to water quality management, generally change the water every 7-10 days or so, and the amount of water changed each time is one-quarter to one-fifth, if it is pure water, it can be added directly to the water tank, if it is tap water, it needs to be exposed to the sun for 1 day.
