New Zealand Mud Snails 

New Zealand Mud Snails (NZMS) (Potamopyrgus antipodarum) are a recent invader in the streams and rivers of the Great Lakes region, and with support from the State of Michigan through the DNR/EGLE Invasive Species Grant Program and Trout Unlimited our research seeks to: 

• Provide early detection of NZMS across the state using visual surveys and environmental DNA (eDNA) sampling 

• Engage citizen scientists (mostly flyfishers) in tracking spread

• Quantify impacts to river ecosystems, invertebrate communities, and fish condition

• Work with entities in states across the region to develop detection and management strategies
