CATDOLL : CATDOLL: Green shrimp, also known as river shrimp, is widely distributed in my country. How should it be farmed?

River shrimps have high requirements for their living environment, and the water quality of the breeding site should be kept clean. The location of the breeding site should be pollution-free and away from factories, because some factories do not pay attention to sewage discharge and directly discharge into the river. The width of the shrimp pond in the breeding base should be about 3 mu and the depth should be about 2 meters. The bottom of the shrimp pond can be made of sandy soil with a little silt as the substrate. A dense net of about 2.5 cm should be installed at the water inlet and outlet to prevent river shrimps from escaping. The breeding methods of river shrimps include the selection of breeding sites, the preparation of feeds, the stocking of shrimp fry, and the daily management of shrimp ponds.

Breeding site: Choose a place without pollution, and install tight nets at the water inlet and outlet of the shrimp pond. Feed preparation: The feed should be balanced and replaced in time. Stocking of shrimp fry: Control the density of shrimp fry stocking according to the size of the shrimp pond. Daily management. Carefully observe the water quality, ensure the cleanliness of the water, and do a good job of cleaning and disinfection in the shrimp pond. After 10 days of shrimp fry stocking, gradually add water, 10 to 15 cm per week. Change the water by 20 to 30 cm every 2 to 3 days in the hot season.

Every half a month or so, 5-10 kg of quicklime slurry is sprinkled throughout the pond, which not only improves the water quality and bottom quality, but also sterilizes and disinfects, and promotes shelling and growth. At the same time, 1‰-3‰ of garlic bait should be mixed in 15-20 days, and used continuously for 3-5 days. It is advisable to choose a freshwater pond or shrimp pond with an area of ​​3-5 mu, a water depth of 1.5-2.5 meters, sufficient freshwater source, no pollution, and a sandy bottom. Generally, a cross-shaped shrimp collection ditch is dug at the bottom of the pond, with a width of 70-80 cm and a depth of 30-40 cm, so that shrimps can be collected in the ditch when harvesting river shrimps in autumn, which is convenient for picking up.

In the breeding process, some sandy soil or silt soil should be used. You can choose a dense net of 2.5 cm to 3 cm, which can prevent escape. Secondly, change the water every two to three days. Do a good job of disinfection. You should also choose some unpolluted places. You can choose a pond.

You must choose a suitable breeding site and high-quality species during the breeding process. You can breed in reservoirs or ponds. You must choose high-quality feed. The water quality must be clear. The height of the fish pond should not exceed two meters. The water resources must be replaced regularly. The oxygen in the water must be guaranteed. Pay attention to the breeding area.

Be sure to pay attention to the quality of the water, pay attention to the sugar intake, choose the right species for breeding, be sure to pay attention to temperature issues, pay attention to plankton, and pay attention to pH values.
