NAS - Nonindigenous Aquatic Species

water
Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency groups, and the general public. The geographical coverage is the United States.

The NAS site will no longer serve data or track aquatic plants or marine invertebrates (except for Asian tiger shrimp - Penaeus monodon). Plants are being discontinued due to budgets cuts. Marine invertebrate data can now be obtained from our partners at the Smithsonian Environmental Research Center from their National Exotic Marine and Estuarine Species Information System (NEMESIS).

The NAS system will focus on freshwater introductions and fishes (freshwater and marine).
