CHICAGO (WBBM NEWSRADIO) -- One of the Shedd Aquarium's newest employees will be researching invasive species in Lake Michigan and try to answer a question: Is there some upside to the invasion?

Research Biologist Scott Colborne is quick to say that there is no across-the-board positive or negative with Lake Michigan's invasive species.

But, follow this: Zebra mussels and quagga mussels invaded, and round gobies invaded.

The gobies eat mussels.

Now, the question is: Do Lake Michigan's native bass enjoy eating invasive gobies?

"This could be a major food source for these fish that are part of the recreational fishery now in the area,” Colborne said Thursday. “And we're not sure if they are.

"There are other indications in Lake Ontario, but the lakes -- you can't consider them exactly the same. So, we have to ask the questions here as well.”

Colborne says the invasive gobies could be a great thing for bass, which could be good for recreational fishing here.
