Scylla serrata and Scylla tranquebarica are the common mud crabs occurring in the estuarine and mangrove areas along the East coast of India. Scylla serrata is commonly called as “red crab” and it prefers to live in low saline waters, whereas S. tranquebarica, the “green crab” lives in high saline waters. Male crabs of S.
Over the years, commercial production of mudcrab (Scyllaspp.) has been undertaken only in bamboo – or net-fenced brackish water ponds. Its feasibility was proven trough a series of verification trials conducted in commercial ponds by SEAFDEC/AQD researchers and is now practiced elsewhere in the country. Of late, the introduction of using net enclosure to grow
Although the technology applies to all three species of mud crab (Scylla serrata, S. tranquebarica, S. olivacea), S. serrata or giant/king crab has been the focus of culture due to its economic viability. Healthy mature crabs with complete limbs are chosen as breeders. The crabs are maintained in the tank until they spawn (release of
To produce food through aquaculture without sacrificing the environment is an apt description for the culture or fattening of mudcrab in mangrove areas. The use of net enclosures in mangroves or tidal zones offers a better alternative to pond culture. It also promotes a better image for brackishwater aquaculture that had been linked to the
Mud crabs, locally known as alimango, inhabit brackishwater and marine environments and prefer muddy and sandy bottoms. They dig deep burrows in mangroves and soft substrates in shallow or intertidal waters. Mud crab juveniles (crablets) are obtained from the wild and recently from the hatchery. Crablets are cultured for 4-5 months. Lean crabs are fattened
