Blue Swimming Crab  (BSC)  is one of  the important fisheries commodities in Indonesia.  This commodity is a top three of Indonesia’s main exports after shrimp and tuna.  However, this crab population continues to decline.   This study aims  to  investigate  the  BSC industry and to determine cultivation efforts for sustainability for the last 10 years.  Data was collected from references and  analysis using bibliometrics .   Every year, Indonesia exports more than  27.000  tons of crabs with a value of 422.000.000 USD .   More than hundreds of countries as  crab importers from Indonesia and C hina are the biggest crab importers, followed by  the USA, Japan, Canada, and other countries .   There was still a high potential  for crab markets around the globe .  Data from  the  Ministry of Marine and Fisheries Affairs  Republic Indonesia showed that m arket share in China is just approximately 17%, USA 11,9%, Japan 5%,  and  Canada 4,7 %.   Aquaculture effort  was mad e to support  the  crab industry, including domestication.   Domestication has been done since 2015.  Using domesticated broodstock followed by consistently  implementing a  proper method will produce a high survival and growth rate of BSC.   Some challenges that  are  faced by crab cultivation are  the high mortality of larvae and juveniles due to disease and cannibalism.  The disease outbreaks occurred when the water quality wa s poor and low feed nutrition. The high productivity of crab cultivation could be achieved when feed management ,  nutrition,  and  water quality are conducted consistently .  The other factors that have to be concern , which  relate to  biosecurity and  using a shelter for protecting the crab during cultivation.
