USFWS eDNA Database for Invasive Carp Detection in Midwest and Northeast

U.S. Fish and Wildlife Service (USFWS) invasive carp environmental DNA (eDNA) sample data supports early detection and monitoring. The data includes detection summaries and static maps, shared via public ArcGIS Online layers and dashboards. A positive eDNA detection indicates the presence of carp DNA, which may originate from live or dead fish or be transported via other vectors.

Use Cases

• Modeling invasive carp spread based on eDNA detection data mentioned in the description
• Creating early warning systems for water bodies based on positive eDNA results
• Visualizing detection patterns and hotspots using the provided geospatial maps and layers
• Assessing environmental transport pathways for eDNA as described in the data caveats

Strengths

• Data is collected and processed by the authoritative U.S. Fish and Wildlife Service (USFWS)
• Includes public-facing geospatial tools like an ArcGIS Online Feature layer, Web Map, and Dashboard
• Last updated date is explicitly provided: 2026-04-14 16:43:31.892392

Limitations

• Row count, column definitions, and sample data are unknown, limiting suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
• A positive eDNA detection does not confirm live fish presence, as noted in the description
