A $275 million plan to keep Asian carp from reaching Lake Michigan -- and the Great Lakes system -- drew both criticism and praise at a hearing in Chicago.

Researchers recently announced the discovery of over 7,000 grass carp eggs in a Lake Erie tributary.  The good news? This isn’t the Asian carp species we’re trying to prevent from entering the Great Lakes.  The bad news? Grass carp pose a different threat. 

Asian carp is a catch-all term for four different species of invasive carp: black, grass, silver, and bighead. 

The Asian carp captured this summer near the southern tip of Lake Michigan -- triggering a big scare -- apparently slipped past electric barriers.


In a long-awaited report, the U.S. Army Corps of Engineers says new measures are needed to prevent Asian carp from getting into the Great Lakes.

The report says the current defense at the Brandon Road lock in Illinois – an underwater electric barrier – should be beefed up. The Army Corps' recommended plan would add water jets and complex noises – like the underwater recordings of a boat motor.

New regulations from the State Department of Environmental Conservation are out this week, aimed at protecting natural resources. The regulations identify more than 100 invasive plant and animal species that have the potential to harm New York’s environment and ways to prevent their release.
