The prawns, Macrobrachium species belonging to the family Palaemonidae are decapod crustaceans of high economic importance world-wide and have been subjected to intense aquacultural practices
especially in Asia and the Americas. Macrobrachium rosenbergii is one of the best farmed species in this family. FAO (Food and Agriculture Organisation of the United Nations) gave details of its identification, profile, production, statistics, status and trends. Global production of M. rosenbergii has increased to over 200,000 tonnes/yr by 2002.
Macrobrachium species occur commonly in the West African region and constitute an important part of the artisanal fishery. Two species of these prawns Macrobrachium macrobrachion and M. vollenhovenii are important food items and are good items for exports when fully recruited for aquaculture.
