Culture method of base shrimp

The size of the breeding site is 2-5 mu, and the water depth is 1-2 meters. The farm will be thoroughly cleaned and disinfected, and the bait should be fertilized about a week before seedling release. The release of seedlings is about the end of May, and desalination and dechlorination should be carried out one week before release. Do a good job in daily management, mainly water quality, feeding, disease prevention and management and so on.

1. Site selection

Breeding grounds and other fish and shrimp sites are similar, can build or use rural ponds, the size of 2-5 mu is appropriate, the best water depth between 1-2 meters, ponds with some slope, slightly inclined, which is conducive to drainage. The water quality of the culture pond must be high. Compared with other fish and shrimp, Kei Wai shrimp has higher requirements for water quality and is more sensitive to water pollution. Clear water quality is the key point to ensure its molting and growth.

2. Cleaning and fertilizing bait

After preparing the breeding site, it should be fully cleaned and disinfected. after emptying the pond water, the pond can be exposed for 2-3 days before entering the water, while those ponds with more silt need to be exposed to the sun for about a month, and should be strictly disinfected after entering the water. can be common quicklime or bleach disinfection. Jiwei shrimp feed on plankton, so about a week before release, it is necessary to fertilize and cultivate bait, the basic biological bait in the shrimp pond, mainly organic fertilizer and inorganic fertilizer.

3. Release seedlings

The prawns are suitable to grow at a water temperature of 18-30 degrees, so they are generally released in late May, when the temperature is more stable and suitable for seedling release. In order to ensure the survival rate of shrimp seedlings, desalination and dechlorination should be carried out one week before release, and they should be temporarily reared in water with a salt content of 1.003 for a week before they can be moved into the culture pond. Desalination must be carried out step by step and must not be on a whim. Can be carried out at the same time as fertilization and bait.

4. Culture management

When the shrimp seedlings enter the pond, it is the daily management, mainly water quality, feeding, disease prevention and management and so on. Water quality management is extremely important. Shrimp seedlings should be restocked for about 10 days. Water should be gradually added and quicklime or bleach should be used to improve water quality, disinfect and sterilize. When the water temperature reaches 24-30 degrees, the food intake of base shrimp will increase greatly, and this is also the period of its rapid growth, so it is necessary to increase feeding to ensure the source of food; disease management is mainly to prevent, sprinkle quicklime mold regularly in each period of time, and supplement calcium to promote shelling growth.
