The Impact of the Diporeia Decline on the Competitive Interactions and Distributions of Slimy and Deepwater Sculpins in Lake Michigan

Slimy and deepwater sculpin are relatively abundant in Lake Michigan  and play an important role in the aquatic food-web. Known as forage  fish, sculpin provide food for larger, predatory fish. In turn,  sculpin feed on a bottom-dwelling organism called Diporeia, which has  experienced sharp declines in recent years. To shed light on how the  Diporeia decline may impact the Lake Michigan food-web, researchers  will examine the distribution, diet and growth of slimy and deepwater  sculpin.
