The first confirmed specimens of Asian tiger shrimp taken from the Gulf of Mexico were in December 2007. Introductions of tiger shrimp into the southeastern US are most likely explained by escapement from aquaculture facilities following flooding by storms and hurricanes, or through migration from areas where tiger shrimp have previously become established in the wild. Although they are less probable, other pathways of introduction (e.g. ballast water discharge) are also possible. Currently, the impacts of this invasive shrimp on the native fauna in areas where it has been introduced are uncertain.", "mapName": " Nonindigenous Aquatic Species database - USGS", "description": "A central repository for spatially referenced biogeographic accounts of introduced aquatic species for the US Geological Survey.
