ALLEGAN, Mich. - Officials say genetic material of Asian carp has been found in a river in the Kalamazoo River in southwestern Michigan.

The state Department of Natural Resources and the U.S. Fish and Wildlife Service on Tuesday announced DNA from silver carp was detected in one of 200 samples taken in July the Kalamazoo River in Allegan County. The river flows into Lake Michigan.

Officials say the discovery marks the first time so-called environmental DNA for silver carp has been found in Michigan's Great Lakes waters outside of Maumee Bay in Lake Erie. In a statement, the agencies say there's "no evidence that a population of silver carp is established."

The silver carp is one of the Asian species threatening to invade the Great Lakes and compete with native fish for food.
