Growth of juveniles of Penaeus monodon of 18-26 mm length range in nursery and stock ponds containing water of low salinity (0.16-0,28 ppt) was very rapid. When this species was reared in a 0.25 ha pond in combination with Indian and exotic carps and Mugil cephalus at an overall density of 8,000 per ha, through multiple stocking and repeated harvesting a higher percentage of retrieval of the prawn was obtained. The growth in the rainfed ponds in Sunderbans was compared with that reported from elsewhere. Gradual acclimatisation of seed reared for 32 days to a salinity of 1.5 ppt before transport and a density of 54 seed (18-26 mm long) per litre without oxygen resulted in 10% survival during transport involving a journey of 3 hours.
