The result: a clearer lake that is becoming an increasingly barren, hostile environment for fish and other aquatic life, particularly salmon and the fish they eat.

There are 186 invasive species in the Great Lakes, 57 of which were imported by ocean freighters that reach the lakes through the St. Lawrence Seaway.
Quagga mussels are widely regarded as the most destructive invasive species to colonize the Great Lakes, surpassing even the ravenous sea lamprey.
