In this June 13, 2012, file photo, Asian carp, jolted by an electric current from a research boat, jump from the Illinois River near Havana, Ill. A fishing method originally developed in China will be used to remove invasive Asian carp from Kentucky Lake and Lake Barkley. The "unified method" of fishing drives carp through a series of large nets into a containment area, where they can be harvested. The method has been successful at capturing large quantities of Asian carp in Missouri and Illinois. John Flesher/AP File photo
