Detecting Invasive Species in the Field: Portable eDNA Screening Tool

The USGS field tested the use of a portable hand-held kit for the detection of the environmental DNA (eDNA) of Asian carps (bighead carp and silver carp) in water samples as part of on-going invasive species detection research. The goals of the USGS-led research are to develop a method and kit that can be used on-site to detect Asian carp eDNA within one hour.
