Matters needing attention in freshwater shrimp culture:

1, winter stocking should be carried out in sunny morning, and summer and autumn stocking should be carried out in sunny morning or rainy day to avoid sun exposure.

2. Wash shrimps with 3% ~ 5% salt water bath 10 minute before stocking to kill parasites and pathogenic bacteria.

3. Shrimp species purchased from other places should be treated slightly before stocking because they are out of water for a long time. Soak the shrimp seeds in the pool water for 1 min, lift them for 2-3 minutes, then soak them for 1 min, and repeat this for 2-3 times, so that the surface and gill cavity of the shrimp seeds can absorb enough water before stocking them, so as to improve the survival rate.

4. In the pond where crayfish are raised, some silver carp and bighead carp are mixed appropriately to improve water quality and make full use of bait resources.

Daily management of freshwater shrimp culture;

1, establish a patrol pool inspection system. Patrol the pool every day, and take countermeasures in time if any abnormality is found. ?

2. Control water quality. Keep the dissolved oxygen in the shrimp pond above 5g/L, the pH value is 7 ~ 8.5, and the transparency is about 40cm. Change the water every15 ~ 20 days, and change the water every time13. Sprinkle quicklime water every 20 days, and use quicklime 10 kg per mu at a time. Keep the water level stable, not up and down.

3, strengthen the management of habitat molting sites. There are always many aquatic plants in the shrimp pond. It is forbidden to disturb a large number of shrimps when molting, and feed high-quality palatable feed immediately after molting to prevent killing each other and promote growth.

4. Prevent escape and disease. Strengthen inspection in flood season to prevent shrimps from escaping. Do a good job in disease prevention and enemy damage removal.
