The U.S. Army Corps of Engineers is taking some innovative, and perhaps unusual, steps to keep Asian carp (the silver and bighead carp in particular) from infesting the Great Lakes. From a report on Cleveland.com:
The U.S. Army Corps of Engineers has an aquatic house of horrors planned for invasive Asian carp threatening the Great Lakes.
The gauntlet of irritation is part of a "layered defense" of Lake Michigan that the Corps is preparing to implement over the next several years to thwart the arrival of undesirable carp by way of Chicago-area rivers and canals.
If the noise won't drive them away, then perhaps the curtain of bubbles will. And if neither are successful then ideally a shot of electricity will do the trick.
The first part of this effort was just awarded a $225 million grant, and the federal government will ultimately spend close to $1 billion on the effort.
