Freshwater shrimp farming attention:

1, clean pool disinfection< /p>

Shrimp fry stocking 20 to 30 days before the pool drained, remove excessive silt, repair the ridge, 75 kilograms of quicklime per acre or bleaching powder, bleaching agent and other drugs, thoroughly clean the pool disinfection.

2, water plant cultivation

Pond disinfection in the pond around the pond slope 70 cm water level line planting hollow cabbage, peanuts, bitter grass and other plants to form a grass belt, grass belt width of about 1 m, spacing 0.2 m, accounting for the total area of the pond of about 15 to 20%.

3, seed stocking

Shrimp pond water temperature stabilized at 20 ℃ above the shrimp seedlings can be placed, it is best to stock through the greenhouse or greenhouse for intermediate cultivation specifications in 1.5 cm above the survival rate of more than 75% of the juvenile shrimp, stocking amount of 2 ~ 25,000 tails / mu.

4, water quality management

Shrimp ponds should pay attention to water quality management, so that the pool water to maintain "fat, live, tender, cool" transparency of 30 ~ 40 cm, PH value of 7 ~ 8, dissolved oxygen is not less than 1 mg / liter, if the water quality is acidic, can be adjusted by splashing lime regularly.
