TRAVERSE CITY, Mich. (AP) - The Obama administration plans to spend $51.5 million this year in its continuing battle to protect the Great Lakes from destructive Asian carp.
Federal officials announced their carp strategy for 2012 on Thursday. It includes first-time water sampling to determine whether bighead and silver carp have reached vulnerable sections of Lakes Michigan, Erie and Huron.
Other planned measures include stepped-up netting and trapping of Asian carp in the Illinois River. Also high-tech monitoring to determine if an electric barrier near Chicago is adequately blocking the carp's path to Lake Michigan.
Authorities also plan field tests of an acoustic underwater gun that could scare carp away and pheromones to lure them to places where they could be captured.
