Freshwater prawn production in I ndia that includes farming and wild capture of the giant freshwater prawn, M acrobrachium rosenbergii and the monsoon river prawn, M . malcolmsonii has increased steadily since 1999 reaching a peak output of 42 780 t in 2005, but then declined to 6568 t in 2009–2010. Stunted growth and diseases in ponds because of poor seed quality and the broodstock which had been inbred over several generations; pond water quality issues; and increased cost of production on account of feed, labour and the mandatory certification requirements are suggested to be some of the factors leading to the production declines. While majority of the output occurs in A ndhra P radesh, single crop paddy–prawn production systems in the low‐lying fields of K erala have helped gradual transformation to a sustainable, organic mode of farming of both rice and prawns, suitable for other states of I ndia. Although the trends by J une 2011 indicate that the sector is set to a revival, future prospects of freshwater prawn farming in I ndia will also depend on the expansion of whiteleg shrimp L itopenaeus vannamei that was introduced recently in I ndia and provided a more profitable opportunity for farming.
