Funding provided by the U.S. Environmental Protection Agency through the Great Lakes Restoration Initiative, U.S. Geological Survey, and U.S. Fish and Wildlife Service supports the evaluation of two experimental invasive carp deterrents. These deterrents include a BioAcoustic Fish Fence at Barkley Lock and Dam on the Cumberland River near Grand Rivers, Kentucky, and the Underwater Acoustic Deterrent System at Lock No. 19 on the Mississippi River near Keokuk, Iowa. The goal of these evaluations is to identify potential new technologies for use with complementary methods to protect the Great Lakes basin from invasive carp. Two interim project updates have been released as Open File Reports that provide information from the first two years of operation and evaluation for each study. Invasive carp and native fish behaviors were monitored in response to each experimental deterrent.
