Description 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.
