IISG in the News: Invasive creatures spread to Fox River, Chain O’ Lakes

Posted June 10th, 2009 in Aquatic Invasive Species, News

From the Northwest Herald:

Local waters might seem clearer to the naked eye, but the reason behind it could disrupt the food chain and eventually the fish supply.

Zebra mussels, which are spreading throughout the Chain O’ Lakes and the Fox River, filter through a liter of plankton-filled water a day each as they go, said Pat Charlebois, aquatic invasive specialist with the Illinois Natural History Survey and the Illinois-Indiana Sea Grant program.

But those plankton, which fog the water, are needed to serve as the base of the food chain.

“[Zebra mussels] are bad,” Charlebois said. “Because they’re removing particles from the water, some people think the water becomes clearer. Lake Michigan is clearer now, but that is because there’s no food.” Read more.
