Invasive red swamp crayfish have been discovered for the first time in Cass County, Michigan.
Red swamp crayfish have been found for the first time in Cass County, Michigan. The Michigan Department of Natural Resources discovered the invasive species last month during a snorkel survey of invasive plants near Niles. The crayfish are native to the southern United States but are prohibited in Michigan waters, where they aggressively compete with native crustaceans, amphibians and fish for food and habitat.
The DNR is asking residents in the greater Niles area, including Berrien and Cass counties, to watch for and report sightings of red swamp crayfish. Anyone who finds one is asked to collect the specimen, freeze it and report it, or to take close-up photographs of the animal's top, sides, underside and claws if collection is not possible. The location, date and time should be recorded.
Potential sightings can be reported to the DNR Fisheries Division. Red swamp crayfish have previously been found in several other Michigan counties, including Livingston, Kalamazoo, Van Buren, Macomb, Wayne and Oakland.
