Current tools for Asian Carp eDNA monitoring fall short, study shows

Since 2010, detections of Asian Carp environmental DNA or "eDNA" have warned scientists, policymakers, and the public that these high-flying invaders are knocking on the Great Lakes' door. Scientists capture tiny DNA-containing bits from water and use genetic analysis to determine if any Asian Carp DNA is present. New research published by Notre Dame scientists shows that the tools currently used for Asian Carp eDNA monitoring often fail to detect the fish. By comparison, the new eDNA methods described in this study capture and detect Asian Carp eDNA more effectively.
