What conditions and techniques are needed to raise river shrimp? How to raise the small river shrimp you catch?

1. Pond: 7 days before stocking, pour new water into the pond to about 30cm, and then apply 50kg of decomposed organic fertilizer per mu of pond. 2. Stocking: In late May, when the water temperature of the pond is stable at 18-20℃, stocking is generally carried out at 30,000-40,000 shrimp fry per mu of pond. 3. Feeding: Feed 2-3 times a day, and the amount of feed should be controlled at about 3-5% of the shrimp body weight.

1. What conditions and techniques are needed to raise river shrimp?

1. Pond treatment

(1) The pond area is 3-5 mu, the water depth is controlled at about 1.5-2.5m, the water source is required to be unpolluted, and the pond has a sandy bottom.

(2) Seven days before stocking, filter the pond using a 60-80 mesh silk screen, fill the pond with new water to a depth of about 30 cm, and then apply 50 kg of decomposed organic fertilizer or 5 kg of urea per acre of pond.

2. Free range

(1) Stocking time: Generally in late May, when the pond water temperature stabilizes at around 18-20℃.

(2) Processing: The shrimp fry need to be desalinated for more than 7 days, and the specific gravity should be below 1.003 before they can be released.

(3) Density: 30,000 to 40,000 shrimp fry (each with a size of 0.7 to 1 cm) are stocked per mu of pond, and 80 to 150 silver carp and bighead carp can also be raised together.

3. Feeding

(1) In the first month, due to the previous water quality cultivation, there is more plankton in the water for the shrimp fry to eat, so there is no need to feed.

(2) After one month, feed compound feed and supplement with fresh fish.

(Note 3) The daily feeding amount should be controlled at about 3-5% of the shrimp's body weight, and it should be fed 2-3 times a day, with one-third of the total feeding amount during the day and two-thirds of the total feeding amount at night. If it is from July to September, the feeding amount can be appropriately increased.

4. Management

(1) After 10 days of stocking, add 10-15 cm of water to each pond every 7 days. If it is a hot season, change the water every 2-3 days, and change 20-30 cm of water each time.

(2) Every 15 days or so, use 5-10kg of quicklime slurry per acre of pond and sprinkle it throughout the pond.

2. How to raise the small river shrimps you caught

1. Equipment: Prepare a fish tank, plant aquatic plants in it, and place appropriate amounts of stones and sand to simulate the wild environment.

2. Water source: It is best to use river water or lake water for breeding. If there is no river water, you can also use tap water that has been exposed to the sun for 2 days.

3. Food: You can feed plankton or bread crumbs, biscuit crumbs, ham sausage scraps, etc.

4. Environment: The temperature should be controlled at around 25℃, and be careful not to expose it to direct sunlight. It is best to place it in a cool and ventilated place for breeding.

How to raise river shrimp?

You can raise shrimps in a fish tank. The shrimps I caught in the pond are doing well in the fish tank. Shrimps like flowing water, preferably flowing water, but if you don't have the conditions to provide it at home, it's best not to use a filter because it can easily suck up the shrimps.

The water quality must be guaranteed, and it will be OK if you feed it appropriately. I don't know what it eats. It seems to be an omnivore. I fed it rice grains and it disturbed it. How to raise it specifically depends on experience.

Additional information:

It is best to use a fish tank with a lid to prevent river shrimp from jumping out of the tank. It is best to plant a water plant and put some pebbles and sand to more realistically simulate the wild living environment of river shrimp.

Feed the river shrimp with foods such as fish leg intestines, bread crumbs, and biscuit crumbs.

Change the water once a week. It is best to use natural running water [river water, lake water]. If not, use tap water that has been exposed to the sun for two days.

River shrimp farming method:

1. First, you should choose a freshwater pond or shrimp pond with an area of ​​3 to 5 acres, a water depth of 1.5 to 2.5 meters, sufficient freshwater source, no pollution, and a sandy bottom.

2. One week before stocking the shrimp fry, filter with a 60-80 mesh silk screen, allow 30 cm of water in, and apply 50 kg of basal fertilizer (fermented animal manure) or 5 kg of urea per mu to cultivate basic bait.

3. Shrimp fry need to be desalinated for more than a week, and can be stocked only when the specific gravity is below 1.003. Generally, 30,000 to 40,000 shrimp fry of 0.7 to 1.0 cm are stocked per mu, and fry below 0.7 cm need to be temporarily raised. Shrimp ponds can be mixed with 80 to 150 silver carp fingerlings of 10 to 20 cm.

4. Shrimp fry mainly feed on plankton in the pond. After one month of weighing, feed them with mixed feed, supplemented with fresh fish, shellfish, etc. The feeding rate is generally 3% to 5% of the shrimp body weight. From July to September, the amount of feed can be appropriately increased, with the principle of no leftover feed. The number of feedings is 2 to 3 times a day, with 1/3 of the amount during the day and 2/3 in the evening.

5. After 10 days of shrimp fry release, gradually add water, adding 10-15 cm of water per week. In the hot season, change the water by 20-30 cm every 2-3 days.

6. Every half month or so, use 5-10 kg of quicklime per mu to make a slurry and sprinkle it all over the pond, which can not only improve the water quality and bottom quality, but also kill bacteria and promote the growth of shelling. At the same time, 1‰-3‰ garlic bait should be mixed in 15-20 days and thrown for 3-5 days.

Additional information:

1. River shrimps are a kind of shrimps with wide temperature and salt tolerance. The temperature range is 10-37℃, the optimum temperature is 17-32℃, and the ability to tolerate low oxygen is stronger than that of shrimps. The general yield per mu can reach 80-150 kg.

2. River shrimps are rich in magnesium, which plays an important regulatory role in heart activity and can protect the cardiovascular system very well. It can reduce the cholesterol content in the blood and prevent arteriosclerosis.

3. River shrimp is a high-quality freshwater shrimp. It has tender meat, delicious taste, rich nutrition, and is a high-protein and low-fat aquatic food, which is quite popular among consumers.

River shrimp is an omnivorous shrimp. It has low requirements for environmental conditions and is euryhaline. It can adapt to almost any environment, including freshwater, high and low temperatures. It can grow in large lakes, ponds, and swamps. It has a short breeding cycle and can usually be caught and put on the market after 3-4 months of breeding. It also has a fast capital turnover. The breeding cost of adult shrimp is low, the profit is high, the nutritional content is high, the taste is delicious, and the food is diverse, which is deeply loved by consumers. There are pond breeding, rice field breeding, cage breeding, large water surface breeding, etc. for adult shrimp breeding.

What treatments should be done to the pond before stocking shrimp fry: There are no special requirements for the pond for growing river shrimp, as long as it can raise fish, it can raise shrimp.

2 to 5 mu is the best, the water depth is 1 to 2 meters, the drainage and irrigation are convenient, the water source is abundant and non-toxic. The pond bottom is preferably sandy or hard mud, and the silt should not exceed 20 cm. The cleaning of river shrimp breeding ponds is basically the same as that of conventional freshwater ponds, except that a cross needs to be dug at the bottom of the pond.

The shrimp-collecting ditch is 70-80 cm wide and 30-40 cm deep, so that the shrimps can gather in the ditch when they are harvested in autumn, making it easier to pick them up. Lime pond cleaning: Apply 100-150 kg of quicklime per mu. You can dig a pit beside the pond, put the quicklime in the pit, wait for it to dissolve, and evenly sprinkle it throughout the pond.

Sprinkle. Stir the pond bottom the next morning to prevent ash from settling on the bottom. Fill the pond with water 3 to 5 days after thorough cleaning. The water should be strictly filtered to prevent harmful organisms from flowing into the pond with the water. Empty the net before releasing the shrimp.

Ten days before stocking, pile 300-500 kg of cow dung or pig dung per mu on the foot of the pond. Turn the fertilizer over every 3-5 days to cultivate zooplankton. When the shrimp fry are stocked, it is the peak period of plankton reproduction in the pond. Adequate bait can promote the rapid growth of the shrimp fry.

In order to provide river shrimp with a habitat, a hiding place and an ecological environment for molting, and to prevent cannibalism, submerged plants are planted in the center of the breeding pond. They mainly include Hydrilla verticillata, Polygonum multiflorum, and Potamogetonida. Usually 4 plants are planted per square meter, and the roots are inserted into the pond mud during planting.
