Two New Invasive Species Found in Michigan Waters

LANSING, Mich. (AP) -- Officials say two new invasive species are now present in Michigan water -- Officials say two new invasive species are now present in Michigan waters. The state Department of Environmental Quality recently confirmed freshwater algae known as didymo in the St. Mary's River near Sault Ste. Marie and New Zealand mud snails in the Pere Marquette River near Ludington. The algae used to be found in small, sporadic concentrations and the snail had never been seen in Michigan before. Experts say both species pose a threat to recreational activities because they can easily attach to boats and fishing gear. The agency is reminding boaters and anglers to take steps to clean, drain and dry their equipment to help prevent the spread of didymo, New Zealand mud snails and other aquatic invasive species.
