Anti-carp effort starts on Mississippi River

– A project involving an experimental underwater speaker system designed to repel invasive Asian carp has started at a lock on the Mississippi River near Genoa.

University of Minnesota researcher Peter Sorensen and his team from the Minnesota Aquatic Invasive Species Center have been raising funds for the project since April, according to the La Crosse Tribune. The U.S. Army Corps of Engineers has granted permission for the project, which uses sounds to drive away Asian carp.

But Mark Clements, who owns Clements Fishing Barge, fears the sounds emitted will impede the migration of native fish species.

“Our sole business is fishing,” Clements said. “If that were to be crippled or hindered in any way, it could mean millions of dollars up and down the river.”

Sorensen, who declined an interview, has said previously that his experiment will not affect native fish.

However, efforts to stop the spread of Asian carp up the Mississippi may be too late, said Ron Benjamin, Department of Natural Resources fisheries supervisor for the Upper Mississippi River.

The invaders have been caught near the mouth of the St. Croix River and near Winona. There are established Asian carp populations in southeast Iowa, and with the high water conditions earlier this summer, there’s a good chance they’ve already migrated north.
