Fish in the Great Lakes

April 22, 2011


Fish found in the upper Great Lakes, Lake Superior, Lake Michigan and Lake Huron are cold water species such as sturgeon, lake trout and whitefish. When exotic species entered the Great Lakes through shipping canals and in the ballast water of ocean going ships, lake trout and white fish became endangered. Pacific salmon were planted to feed upon alewives. So now we have salmon as well as perch, lake trout and white fish in the Great Lakes and sports fishers like to catch them.

In the lower Great Lakes, Lake Erie and Lake Ontario, salmon have also been planted on an experimental basis. Warm water species such as walleye are endemic to Lake Erie. Lake Ontario is also fished for salmon and trout. To read more about fish in the Great Lakes, read The Dynamic Great Lakes.
