Roche shrimp farming needs to meet the following conditions and methods:
First, breeding conditions.
Pond conditions: The pond should be a sediment bottom, which is conducive to the burrowing of Roche shrimp. The area of the pond is generally about 10 acres, and the water depth is 1About 5 meters, the water quality needs to be fresh and pollution-free.
Bait management: Roche shrimp is omnivorous and needs to be fed an appropriate amount of plant-based bait and animal-based bait. Plant-based baits can choose aquatic plants, duckweed, etc., and animal baits can choose small fish, small shrimp, etc.
Water quality management: Roche shrimp has high requirements for water quality, and the water needs to be replaced regularly to keep the water clear and dissolved oxygen sufficient. Generally, the water is replaced once a week, and the amount of each replacement is about 10% of the total water volume of the pond.
Daily management: Daily management includes patrolling the pond, observing the growth of shrimp, checking the feed feeding, etc. Pond patrols can detect the growth of shrimp in time to avoid problems. Observing the growth of shrimp can adjust the amount of feed in time to ensure the nutritional needs of shrimp. Checking the feed feeding can avoid deterioration of water quality due to overfeeding.
Second, the breeding method.
Seed selection: Choosing healthy seed is the key to successful shrimp farming. Generally, seedlings with a body length of more than 1 cm are selected, and seedlings with strong physique, disease-free and vigorous are selected.
Stocking density: The stocking density should not be too high, otherwise it is easy to cause slow growth or death of shrimp. Generally, 10-200,000 birds are stocked per mu, and they are appropriately adjusted according to the pond conditions and the level of breeding technology.
Feed feeding: Roche shrimp need to take in the right amount of nutrients to grow properly. Generally, it is fed 2-3 times a day, and the amount of feed each time is suitable for shrimp to be eaten within 2-3 hours. The feed can choose special Roche shrimp feed, or you can choose animal bait such as small fish and small shrimp.
Water quality management: Roche shrimp has high requirements for water quality, and the water needs to be replaced regularly to keep the water clear and dissolved oxygen sufficient. Generally, the water is replaced once a week, and the amount of each replacement is about 10% of the total water volume of the pond. At the same time, microbial agents can be used to adjust the water quality to maintain the stability of the water quality and the appropriate pH value.
Disease prevention and control: Roche shrimp is prone to disease and needs to be strengthened. Regular use of antimicrobials and disinfectants for prophylaxis and**. At the same time, pay attention to the growth and activity status of shrimp, find problems in time and take measures.
3. Precautions.
Breeding density should be reasonable: too high breeding density can easily lead to slow growth of shrimp and high incidence of disease, so it is necessary to reasonably control the breeding density.
Feed selection should be appropriate: Roche shrimp need to take in the right amount of nutrients to grow normally, so it is necessary to choose the right feed to ensure the nutritional needs of shrimp.
Water quality management should be scientific: Roche shrimp has high requirements for water quality, and the water needs to be replaced regularly to keep the water clear and dissolved oxygen sufficient. At the same time, microbial agents can be used to adjust the water quality to maintain the stability of the water quality and the appropriate pH value.
Disease prevention and control should be timely: Roche shrimp is prone to diseases and needs to be strengthened. Regular use of antimicrobials and disinfectants for prophylaxis and**. At the same time, pay attention to the growth and activity status of shrimp, find problems in time and take measures.
