Physical Barrier Best Way to Stop Asian Carp, Study Says


The U.S. Army Corps of Engineers recently released a study that suggests physically separating the Mississippi River and Great Lakes watersheds is the most effective way to prevent aquatic species like Asian carp from moving between the two iconic waters.

USACE has previously admitted that a series of electrical barriers designed to repel Asian carp have been easily breached.
