Invasive crayfish pose a substantial threat to aquatic habitats in the Great Lakes Region because of their ability to reduce habitat quality and dramatically alter aquatic food webs. Currently, efforts to prevent the introduction and spread of invasive crayfish consist largely of reducing the size of existing populations and encouraging people to refrain from releasing crayfish into new bodies of water. The ICC focuses on improving upon our collective management and outreach capabilities.
