The U.S. Geological Survey, the U.S. Army Engineer Research and Development Center and partners install a temporary, experimental underwater Acoustic Deterrent System at Mississippi River Lock and Dam 19 between Keokuk, Iowa, and Hamilton, Illinois, on Feb. 3, 2021. The construction is part of a study to understand how invasive Asian carp respond to acoustic, or sound, signals. If the deterrent is effective at controlling upstream movement of Asian carp with limited effects on native species, this or similar technology could be deployed at other critical locations to help prevent the spread of invasive Asian carp.
