  • eDNA from Invasive Silver Carp Identified in Lake Erie’s Presque Isle Bay

    • Jul 21, 2022

    • Pennsylvania Fish and Boat Commission.

    • The Pennsylvania Fish and Boat Commission (PFBC) announced that it has conducted targeted invasive carp sampling in Presque Isle Bay, Erie County, after the U.S. Fish and Wildlife Service (USFWS) detected the presence of Silver Carp environmental DNA (eDNA). While no physical invasive carp specimens have been detected, the PFBC has requested that the USFWS collect additional water samples from Presque Isle Bay in the fall when more favorable environmental conditions are present for eDNA sampling. Members of the public can report sightings of aquatic invasive species to the PFBC using its online form.

  • Minnesota DNR, USFWS Using eDNA to Learn About Invasive Carp

    • Aug 12, 2022

    • Minnesota Department of Natural Resources.

    • The Minnesota Department of Natural Resources and the U.S. Fish and Wildlife Service have been using environmental DNA (or eDNA) technology to detect invasive carp in the St. Croix, Mississippi and Minnesota rivers. May sampling in the St. Croix River showed silver carp eDNA about four miles north of where invasive carp have been confirmed in the St. Croix. eDNA is DNA released from an organism into the environment that is detectable at very low concentrations.

      Invasive carp captures must be reported to the DNR immediately by calling 651-587-2781 or emailing invasivecarp.dnr@state.mn.us. Take a photo and transport the carp to the nearest DNR fisheries office or make arrangements for it to be picked up by a DNR official. Do not release captured invasive carp. A permit can be requested to keep captured invasive carp for consumption or disposal.
