he Michigan Department of Natural Resources (MDNR) and U.S. Fish and Wildlife Service (USFWS) announced that traces of the DNA of silver carp - a species of Asian carp - have been found in the Kalamazoo River in Allegan County, on the west side of the state. The two agencies are collaborating to assess what they term is a "positive environmental DNA (eDNA) result." In July 2014, over two hundred water samples were taken along the Kalamazoo River, from below the Caulkins Dam in Allegan County to the mouth of the river that opens into Lake Michigan. Lab results were reviewed by Michigan's DNR on Oct. 2. One of the of 200 samples, which was taken from just below Caulkins Dam, tested positive for silver carp eDNA.
