Great Lakes USFWS Aquatic Invasive Species Watchlists

The USFWS Great Lakes Aquatic Invasive Species (AIS) watchlist was developed utilizing information from Great Lakes Aquatic Nonindigenous Species Information System (GLANSIS), USFWS Ecological Risk Assessments, the Great Lakes and St. Lawrence Governors and Premiers Least Wanted list, and partner input.

Lists are limited to fish species and provided for each lake and the St. Lawrence Seaway.
