Bioacoustics to Detect, Deter and Eliminate Silver Carp

Silver carp are migrating north up the Mississippi River and pose threats to the native fish and aquatic ecosystems of Minnesota rivers and lakes where they can become established. Additionally, the unique jumping ability of silver carp also places recreational boaters in danger of being injured during collisions with airborne fish. However, it is believed that this jumping ability could potentially be exploited as a weakness to help detect, manage, and control silver carp populations. Researchers at the University of Minnesota – Duluth, in cooperation with the U.S. Geological Survey, are using this appropriation to develop bioacoustics technologies that use sound to stimulate silver carp jumping in order to assist with strategies for detection, capture, and deterrence.
