CATDOLL : CATDOLL: 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.
