Rusty crayfish remain an issue in Torch Lake, hindering native species
Invasive rusty crayfish continue to harm native species in Michigan’s Torch Lake. Conservation officials say the crayfish likely spread through illegal dumping of bait buckets and urge the public to properly dispose of bait and clean fishing gear to prevent further invasion.
Have an event, funding opportunity, or research update that you’d like us to share? Submit your announcements here and we’ll include it in our newsletter next month.
This selection of invasive crayfish information is collected by the Invasive Crayfish Collaborative, a program convened and facilitated by Illinois-Indiana Sea Grant and the Illinois Natural History Survey with funding from the Great Lakes Restoration Initiative.
