Macrobrachium rosenbergii

Macrobrachium rosenbergii

Macrobrachium rosenbergii, known as the Giant River Prawn, is a large catadromous shrimp native to coastal rivers and estuaries from Sri Lanka to Indonesia (Java and Borneo) and north to southern China. Extensive aquaculture of M. rosenbergii began in the 1960s in Hawaii, and became a major economic resource by the 1980s. Major producing countries include the US, Mexico, Peru, Brazil, Iran, India, Thailand, China, Taiwan, Indonesia and Malaysia. Escapes of this shrimp have been reported in Mississippi, Hawaii, Puerto Rico and Guam, and breeding populations are reported in Venezuela, Brazil, and Dominica. Despite frequent escapes, the impacts of Macrobrachium rosenbergii have not been well studied.

*This species is not currently established in North American waters.
