Restoring the Natural Divide

The Great Lakes Commission and the Great Lakes and St. Lawrence Cities Initiative, with support from six funders, embarked on a project in July 2010 to identify engineering options for Chicago's waterway system that will prevent interbasin movement of aquatic invasive species, including Asian carp. The expedited study, now completed,...

Notre Dame researchers demonstrate new DNA detection technique

A team of researchers from the University of Notre Dame have demonstrated a novel DNA detection method that could prove suitable for many real-world applications. Physicists Carol Tanner and Steven Ruggiero led the team in the application of a new technique called laser transmission spectroscopy (LTS). LTS is capable of...

Asian Carp: Threat to Great Lakes

“You’re taking your life in your own hands if you go waterskiing on some parts of the Illinois River,” observes aquatic invasive species expert Phil Moy of the University of Wisconsin Sea Grant.  He’s talking about the Silver Asian Carp that have infiltrated much of the Mississippi River System.

The Threat of Invasive Species

Don't look now but ... THEY'RE HERE! A veritable army of real life monsters is invading whole sections of our country, and so far we're not putting up much of a resistance.

If you can't beat 'em, eat 'em

Notre Dame graduate students Matt Barnes, Andy Deines and Sheina Sim are not your average chefs — really they’re not chefs at all — but they are convinced their studies of invasive species can help you put together both an eco-friendly and appetizing menu for your next tailgate. Working under...

Chicago canal's electric fish barrier does work, tests show

Despite laboratory evidence earlier this year showing that the electrical barrier in the Chicago area has not been strong enough to repel young Asian carp, tagging similar fish species below the barrier and tracking them shows that they are not crossing the barrier, the Army Corps of Engineers said Friday....

Report: DNA Method Helpful in Seeking Asian Carp

Federal officials promised Friday to improve two crucial weapons in the fight to prevent Asian carp from invading the Great Lakes: an electric fish barrier near Chicago and an early-warning system that detects carp DNA in waterways.        

Scientists defend Asian carp research methods

Scientists whose genetics-based research became a lightning rod in the debate over protecting the Great Lakes from Asian carp have made their case in a newly published article that says at least some of the dreaded invaders have gotten beyond an electric barrier meant to block their path to Lake...

Fish Out of Water

The invasion of Asian carp into the waters of the South and the Midwest differs from other ongoing environmental problems.

Scientist: 'Don't Give Up' On Stopping Asian Carp

Fish that have the potential to devastate the Great Lakes ecosystem may be just a few miles from Lake Michigan. Two carp species from Asia — the silver and the bighead — are invasive fish with huge appetites. If they enter the Great Lakes, they could overwhelm the native fish....
