Nonindigenous Aquatic Species Sighting Reporting Form and Alert Registration Form

The U.S. Geological Survey (USGS) is responsible for tracking the status and distribution of introduced aquatic organisms. The purpose of the Nonindigenous Aquatic Species Program (NAS) is to monitor and provide information concerning the status, distribution and potential impacts of non-native aquatic organisms in a timely manner for research, management and education. Information is collected from the public regarding the distribution of nonindigenous aquatic species, primarily fish, in open waters of the United States. This information is vital for early detection and rapid response for the possible eradication of organisms that may be considered invasive in a natural environment such as a lake, river, stream, and pond. These species are not native to the environment in which they are now found. Nonindigenous species can and do have negative impacts on our natives species. Early detection is a major focus of the Bureau. The public can help us with this task by serving as the “eyes and ears” for our Program because the USGS cannot possibly be everywhere, observing and monitoring all open waters for nonindigenous aquatic species.
