ABSTRACT: Populations of Northern snakehead (Channa argus) have been introduced in the Lower Hudson, Bronx, and Rondout watersheds of New York, Lower Delaware watershed of Pennsylvania and New Jersey, and the Lower Susquehanna watershed of Pennsylvania and Maryland. Because these observations are in close proximity to Great Lakes tributaries, Northern snakehead constitute a species of high invasion concern for natural resource agencies of Great Lakes connected waters. Traditional gear capture of Northern snakehead at low densities in their established range can be difficult due to the shallow, vegetation-rich habitat they typically occupy. As a result, significant environmental DNA (eDNA) detection efforts by the U.S. Fish and Wildlife Service and partner agencies in portions of the Oswego River drainage and canal system of New York have been explored. In any eDNA detection effort, it is important to have confidence in the accuracy of the markers used, and particularly when the effort involves the detection of aquatic invasive species where management and/or response actions may be taken. Here we highlight results from validation and comparative performance testing of several eDNA markers designed to detect Northern snakehead DNA and detection results of the 2018 environmental sampling efforts.
