1 Fill the pond with water using double layered filter bags
2 Hold water for 10 to15 days
3 Maintain a water depth of more than 80 cm
4 Fertilize the pond
5 Stabilize the plankton bloom

Fill the pond with water using double layered filter bags
a. Always use double layer of fi ne mesh filter net (300 micron mesh size) to filter the water at water inlet point (water gate).
B After filling the pond, hold water for 10 to15 days
c. If filling pond from reservoir, hold water in reservoir 7 days before shifting to grow-out pond.
Maintain a water depth of more than 80 cm in the shallowest part of pond
Fertilize the pond as per recommended fertilization schedule
Stabilize the plankton bloom (green /brown color water).
• Apply: Super Phospate =25 kg/Ha, Urea= 10kg/Ha, dolomite= 100kg/Ha for 2-3 timts with a gap of 2-3 days after each application.
Do not heavily fertilize the water to get dark green water. It will reduce the oxygen in water during night time thus suffocating the shrimps. It is one of the reasons for lower survival rate of shrimp seeds.
