The United States Geological Survey and its partners like the Army Corps of Engineers are installing an underwater acoustic deterrent system at Lock and Dam 19, in Keokuk, Iowa, to study how sound may be able to stop the spread of invasive Asian carp species.

The invasive fish are harmful because they grow quickly and aggressively compete with native fish for food and habitat. Conservationists have long feared Asian carp will reach the Great Lakes.

"The big concern is that they will get into the Great Lakes and impact the large fisheries there," said Dr. Marybeth Brey, USGS Research Fish Biologist.

Dr. Brey has traveled the country researching Asian carp, which were accidentally introduced into the wild in the 1970s. Without natural predators their populations exploded on waterways like the Illinois River.
