  1. Completely drain out the water from pond to remove disease use a water pump to drain out the water.
  2. Dry the pond bottom Pond should be sun dried at least for 30-45 days during pond preparation
  3. Check the pH of soil. If acidic soil, use lime. Use a soil pH meter to test the soil pH
  4. Wash the soil by water intake and drain 2-3 times

Completely drain out the water from pond
• Helps in removing the disease carrying fish and crustaceans from previous crops in the pond.
• If the shrimp pond is deeper than the
water canal, use a water pump to drain out the water.
Dry the pond bottom
• Sun drying kills fi sh/crustacean and their eggs in the shrimp pond soil
Helps in oxidizing the organic matter thus reducing the sludge
Pond should be sun dried at least for 30-45 days during pond preparation
Remove all the dead fish, shrimp and unwanted materials
Remove the organic waste from pond bottom
Check the pH of soil. If acidic soil, use lime
• Acidic soil causes:
– High shrimp and fish mortality rates
– Low survival rates and poor condition of fish and shrimp
– High disease risk
– Poor algal blooms
– High pond maintenance costs
– Depletion of oxygen due to oxidizing of minerals (metals in soil
• Use a soil pH meter to test the soil pH. Soil should be wet while using this equipment.
• Do not turn the soil (tilling) in acidic soil. If done, the soil will be more acidic.
Wash the soil by water intake and drain 2-3 times to reduce the soil acidity.
Use the dolomite or agricultural lime to neutralise soil acidity as per the dosage indicated in the below
