Prior to stocking, ponds were
dried for 7 to 30 days, soil was tilled and plowed, and dykes were
repaired. Ponds were filled and treated most commonly with lime or
dolomite and salt was often used in nursery ponds at 0.1 to 1.2%
salinity. Prawns were stocked within 1 to 15 days after ponds had been
filled.
