Among Portunid crabs, Scylla species are commercially important in aquaculture, capture fisheries and trade, and have created wide interest and high preference in India. Part of the 70,000 ha of brackishwater ponds developed for aquaculture in the southern states of Peninsular India is suitable for conversion to crab farming. Crab culture technology developed in the Central Marine Fisheries Research Institute has recently led to increasing interest in crab farming. Surveys have been conducted to identify resource grounds and seasons for collection of wild seeds. However the inadequate supply of seedstock is a limiting factor in promoting the expansion of the industry. Environmental manipulation strategies have been developed to maintain broodstock and produce gravid females. Further refinements of hatchery technology could meet the demands for seed supply and promote culture activities. Crab production ranged from 1,500 to 2,500 kg•ha-1•crop-1 using different culture methods. Based on the economics of different culture methods, fattening is more remunerative than monoculture and polyculture. Post-harvesting techniques and marketing aspects are discussed. Management measures are highlighted to promote conservation of stock for sustainable yield.
