1. Breeding site: First, build a breeding pond in a place with flat terrain and clean water quality, clean and disinfect the pond and cultivate aquatic plants. 2. Release shrimp seedlings: It is not recommended to release shrimp seedlings that abuse antibiotics. It is better to release shrimp seedlings that are healthy and disease-free. The release location should be in a sheltered place. 3. Feeding management: In the early stage, shrimp seedlings generally feed on plankton and algae in the water body and do not need to be fed. When feeding is required, they can be fed with snail meat, rice bran and other foods.
1. Grass shrimp farming technology
1. Breeding site
(1) Generally, it should be in a place with flat terrain, close to water sources, good water quality, and no pollution. Build a breeding pond. The area of ??the pond is generally 5-8 acres, the water level is generally about 2m, and it is equipped with an aerator.
(2) Do a good job of clearing and disinfecting the pond, and cultivating aquatic plants to provide an environment suitable for the growth of grass shrimp.
2. Release shrimp seedlings
(1) In order to ensure the quality of grass shrimp culture, healthy, disease-free shrimp seedlings should be released, and shrimp seedlings that abuse antibiotics should not be released.
(2) It is not advisable to release shrimp seedlings at noon. It can usually be released at 9 a.m. on a sunny day or after the sun sets in the afternoon. Shrimp seedlings should be released in a sheltered area.
3. Feeding management
(1) If aquatic plants and algae are cultivated in the early stage, feeding is generally not needed in the first few days after the shrimp seedlings are released. It feeds on plankton and algae in the water.
(2) Grass shrimp are omnivorous shrimps. They can usually be fed bean cakes, clam meat, snail meat, rice bran, raw bran, fish meat and other foods. It is required to feed them in sufficient quantities to avoid spontaneous growth. The phenomenon of cannibalism.
(3) Because grass shrimp have the habit of hiding during the day and coming out at night, the amount of feeding during the day generally accounts for 30-35% of the total daily feeding amount, while at night, the amount of feeding It accounts for 65-70% of the total daily feeding amount.
(4) At the same time, the feeding amount should be reasonably adjusted according to the weather, water temperature, water quality, etc. When the weather is bad, the feeding amount can generally be appropriately reduced, and when the weather is good, the feeding amount can generally be appropriately reduced. You can invest more appropriately.
(5) When the water temperature is between 27-31°C, you can add more water. When the water temperature is higher than 34°C, you can generally add less or no water. When the water quality is poor, you can add less water. If you invest, if not, invest more appropriately.
2. What are the water quality requirements of grass shrimp?
1. The transparency of water quality is generally 30-40cm, the pH value of water quality is generally 8-9, and the salinity is average. It is 0.015-0.025. When the transparency is lower than 20cm, the water needs to be changed in time, because at high temperatures, the water quality is prone to deterioration, so the frequency of water changes can be appropriately increased, and water quality improvers can be used when necessary.
2. The quality of water generally affects the quality of grass shrimp. Therefore, when breeding, it is necessary to patrol the pond frequently and remove food residues in time to ensure the cleanliness of the water and the healthy growth of grass shrimp.
3. During the high temperature season, an aerator needs to be used to increase oxygen to ensure that there is sufficient dissolved oxygen in the water. At the same time, attention should be paid to the prevention and treatment of shrimp diseases. Regular disinfection is required during the entire breeding period. You can use some Biological agents are used to improve water quality to reduce the chance of shrimp disease.
