Macrobrachium rosenbergii popularly known as 'scampi' has been expanding in India recent years. Scampi farming gained momentum after the set-back in shrimp farming due to disease outbreaks and other factors. The infrastructure available to produce shrimp seed and process the shrimp was helpful in providing support to scampi farming. The existing culture system includes both monoculture and polyculture with Indian major carps in ponds. Grow out stocking densities range from 2 2 0.5-2.5 scampi per m in polyculture and 1-5 per m in monoculture. The culture period is 6-8 months starting at the beginning of southwest monsoon (June-July, 27-30°C ). The scampi are fed with farm-made or commercial feeds. This article summarizes the nutrition and feeding of freshwater prawns (grow out), with special reference to culture conditions in India. Freshwater prawn production depends on natural productivity in ponds, but feeds are important to profitability
