How Many Sport Fish Can Lake Michigan Support?

Researchers are paying close attention to food webs in Lake Michigan after several invasive species have appeared, including round gobies and quagga mussels. Through analyzing the body tissue of these species, scientists are able to determine what they are eating- and if they are diminishing the food sources of other Lake Michigan fish.

To learn more about how and why this research is conducted, view the following video by the University of Wisconsin Sea Grant Institute.
