After 2-4 days of liming the pond was applied with semi
dried cow dung. The water colour of each pond was
turned to light green after three days.
Then the water
level was raised and Urea, Triple Super Phosphate
(TSP) and muster cake was added for improving pond
productivity. The larvae of P. monodon (PL 20/
screened for white spot syndrome virus) were
purchased from Matysafed Prawn Hatchery,
Thirumullavaram, Kollam and transported in
oxygenated double-layered polythene bags (Brine
shrimp nauplii was given along with seeds during
packing). The seeds were brought to the farm site and
bags were kept in the pond water to adjust the
temperature.
The ponds were then stocked with
animals that sourced from the same hatchery batch.
The nursery area used for seed stocking was usually
5% of the total pond area.
After that the pond water
was added slowly into the seed bag to adjust the
salinity and pH
