The Illinois and Indiana Departments of Natural Resources, along with several other state, local, and federal agencies, are joining forces to coordinate a survey of Calumet Harbor and Lake Michigan waters. The efforts will help search for and combat aquatic invasive species.

“The exercise – including intensive netting and electro-fishing – will be the first of its kind utilizing provisions of the new Mutual Aid Agreement for Combating Aquatic Invasive Species, signed at the Council of Great Lakes Governors meeting on April 26 in Chicago… 
 
Crews coordinated by the Illinois and Indiana Departments of Natural Resources are deploying boats on Chicago’s Calumet Harbor, and on adjoining waters of Lake Michigan on both sides of the Illinois-Indiana state line, for electro-fishing and netting to determine whether invasive Eurasian ruffe are present.
 
‘Aquatic invasive threats know no national or state boundaries. Our ability to sample fish communities, respond quickly, and effectively communicate on efforts could be critical in the future to respond to a threat within the Great Lakes basin,’ said Indiana DNR Aquatic Invasive Species Coordinator Eric Fischer.
 
Eurasian ruffe, an eastern European species of fish, have been found in Lake Superior since the mid-1980s, have a similar diet and feeding habits of native fish, and could present problems for the food web in Lake Michigan. Researchers detected environmental DNA of Eurasian ruffe in Calumet Harbor last year.”
