Soft Shell Crab Farming in Southern Thailand


In southern Thailand, many families run small, soft-shell crab farms.  Seasonally, they collect juvenile crabs from the wild and grow them to market size.  The collection areas should be as close to the farm as possible because mortalities can be high during transport.  When blue crabs are transported in water, however, the survival rate can be as high as 95%.


Dr. Banchong Tiensoonremee, Associate Professor of Chulalonggong University in Bangkok runs an indoor, recirculating crab farm funded by the Thai Ministry of Agriculture.  He farms his crabs in covered plastic boxes within concrete raceways.  The farm has been in operation for four years.  After harvest, the crabs’ gills and eggs are removed, and the crabs are treated with ozone because they must have low bacterial counts.  Then, they are frozen for export to Japan and the European Union.


There are about 756 soft shell crab farms in the Ranong District of southern Thailand that cover 1,458 hectares, employ over 20,000 people and produce 150-200 metric tons a month.   These farms import small crabs from Myanmar and grow them to market size.  They are marketed live (80 to 85 percent survivals) in bamboo baskets.


There are also large floating-box crab farms in Ranong and Satun, Thailand.
