No genetic evidence of Asian carp found in Kalamazoo River in latest round of tests

Michigan Department of Natural Resources

The most recent round of environmental DNA sampling on the Kalamazoo River showed no evidence of genetic material from Asian carp, according to the Michigan Department of Natural Resources.

Ed Golder, spokesperson for the department, says this is very good news, "but it doesn't mean that we're going to stop being vigilant about the concern that Asian carp generally, and silver carp and big head carp in particular, pose to the Great Lakes."

Golder said the October sampling followed samples taken in June and July.  Just one sample, out of 600, showed the presence of Asian carp environmental DNA.

"That earlier positive result remains a concern, and we will continue to closely monitor this section of the Kalamazoo River because of it," he said.

Golder said no Asian carp have been found in the Kalamazoo River, which flows into Lake Michigan. In addition to live fish, genetic material can enter bodies of water through bird droppings, boats, and fishing gear.

The DNR says anglers and boaters are a first line of defense against Asian carp and other invasive aquatic species. It urges them to drain all water from their boats and clean their gear after each trip. It also asks them to report any sightings of Asian carp.
