He also spoke about how, unlike the other four Great Lakes, Lake Erie is surrounded by agriculture and a more urbanized landscape.

Yellow perch are a staple of firehouse and church fish fries, and the delicate fish on that dish might once have lived in the Great Lakes. But warmer lake waters in a changing climate threaten the yellow perch population as well as other popular cool water fish, like walleye.
The Great Lakes are changing. Warming air and water, shorter winters with less snow and ice and more extreme weather are impacting the lakes and the fish that live there. In addition, harmful algal blooms are creating dead zones that are bad news for fish, and impact recreational users as well.

We kick off our week-long series In Warm Water: Fish and the Changing Great Lakes with a look at Lake Superior.

But Lake Superior’s future could look radically different. Warming water and decreasing ice are threatening the habitat of some of the lake’s most iconic fish.
