USFWS Midwest and Northeast Regions Bighead and Silver Carp environmental DNA (eDNA) Database

Published by U.S. Fish and Wildlife Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2025-02-12T00:00:00Z
The invasive carp environmental DNA (eDNA) sample data was collected and processed by the U.S. Fish and Wildlife Service (USFWS) and is used for the early detection and monitoring of invasive carp. The reportable eDNA detection summary data along with static maps are shared with the public along with a public facing ArcGIS Online Feature layer, Web Map, and Dashboard. For further information on data collection and processing please refer to the Quality Assurance Project Plan eDNA Monitoring of Bighead and Silver Carps (see files and links). Additional information on the Invasive carp eDNA program for the U.S. Fish and Wildlife Service can be found on the Whitney Genetics Lab Facility web page (see files and links). A positive eDNA detection result means there was invasive carp eDNA in the water body, which can be from live or dead fish, but it could have also been transported via boat, bird, or water current. A positive eDNA detection does not necessarily mean there were invasive carp present at the time samples were taken. For more information or questions, please contact the eDNA Program Coordinator, Nick Frohnauer at (nicholas_frohnauer@fws.gov). Complete ISO 19115 FGDC metadata can be found under the hosted view feature layer on the FWS AGOL platform.
