Mud Crab Farming from Hatchery Produced Seedstock


Soft-shell crabs command a higher price than crabs with hard shells because they can be eaten whole—shells and all.  In Asia, commercial soft-shell crab farming is established in Thailand, Myanmar, and Vietnam.  Soft-shell crabs are sold to local restaurants and exported to Hong Kong, Singapore, South Korea, Japan, Europe and the United States.


Most soft-shell crab farming, however, involves sourcing wild seedstock, resulting in the depletion of natural resources.  This problem has been addressed in a project funded by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) that showed it was feasible to produce hatchery-reared mud crab (Scylla serrata) juveniles for farming, assuring farmers of a year-round supply of seedstock.


In communal rearing, crabs are stocked in tanks or cages installed in a pond, while in individual rearing, the crabs are maintained in perforated plastic boxes that are held in pontoons or floating platforms.  Newly molted crabs are retrieved, sorted, held in freshwater, packed and stored in freezer prior to marketing.
