    Aquaculture is one of the fastest growing food production sectors in the world, providing an acceptable, protein rich supplement to and substitute for, wild aquatic animals and plants. Over the time, production from aquaculture has increased steadily with the introduction of new species and many countries are venturing into it. Crab culture is popular now and good demand is there in domestic and foreign markets.Most of the edible crabs caught from marine and brackish water environments belong to the family Portunidae. In seas around India, five genera of portunid crabs have been reported by various authors, Scylla, Portunus, Charybdis, Lupocyclus and Thalamita and among them the first three genera are commercially important.The annual marine crab landing in India has shown increasing trend during 1975- 2021 and recorded a tremendous decline during 2020 & 2021. Maximum landings registered dring 2018 (57354 t) and minimum during 1978 (14202 t). The commercially important species are Portunus sanguinolentus, P. pelagicus, Charybdis feriata, C. lucifer, Scylla serrata and S. olivacea. Crab culture gained momentum during 1990‟s due to the great demand of live crabs and crab products in the export market. In the past crabs were considered a secondary species to shrimps and finfishes. For centuries, the portunid crabs have constituted an important secondary crop in the traditional tidal ponds of Asia, the stocking of crabs was entirely passive, and it enters through the sluice gates along with young ones of other species. They were considered to be undesirable components of the typical multi species culture system, because of their “troublesome” habits of destroying pond dikes, escaping, cannibalism and damage to other species during harvest. Now the picture is changed and crabs farming picking up rapidly due to promising market and profitability.
