Some foreign species that have invaded the Great Lakes
By Associated Press, 4/14/2000 00:46

Some harmful foreign species that have invaded the Great Lakes:

Eurasian ruffe small spiny perch native to the Black and
Caspian seas that competes for food resources with Great
Lakes fish. It was introduced by ballast to the Duluth Harbor
on Lake Superior.

Zebra mussel mollusk from Asia that reproduces rapidly and
clogs waterways. It is believed the mussel was introduced by
ballast in Lake St. Clair.

Goby small bottom-dwelling fish that takes over spawning sites
and competes for resources. It was first introduced into Lake
St. Clair in 1990 from a transoceanic ship.

Sea lamprey jawless fish that feeds on other fish with its large
sucking mouth and sharp teeth. The Atlantic Ocean native
migrated up the Erie Canal.
