Broadcasting underwater noise may be a sound solution for repelling Asian carp on Mississippi River

How can Asian carp be stopped? That is the question that biologists and other researchers have been working on for many years in their continuing quest to deter the invasive species from advancing up the Upper Mississippi and many other rivers.
