The lakes don't have herring, anchovy nor krill.
I grew up on the shores of Lake Huron. The Great Lakes have the alewife, which is a member of the herring family and related to the shad. In fact, we called it shad when I was growing up.
The alewife is invasive (it's native to the Atlantic Ocean) and gained access to the Upper Great lakes via the Welland Canal. In the 1940's/50's, Pacific Salmon were introduced, in part, into the Great Lakes to control the alewife population .
As a kid in the late 70's I can recall huge alewife/shad die offs and the shore would be just littered with dead fish.
