Macrobrachium macrobrachion
Macrobrachium macrobrachion, Brackish River Prawn, is a caridean shrimp native to brackish and fresh waters of West Africa, from Senegal to northern Angola. This species supports an important commercial fishery in West African coastal rivers. It is considered to have potential for aquaculture and may have been imported for research for this purpose. It was collected once in Florida in the Indian River Lagoon, but has had no known ecological or economic impacts in the US.
*This species is not currently established in North American waters.
