Much needed attention has been directed at some particularly problematic aquatic invasive species in the Great Lakes, such as Asian carps and zebra and quagga mussels. But others invaders, like crayfish, can also take their toll on the lakes. Illinois-Indiana Sea Grant (IISG) has created a new collaborative that brings together a variety of experts and stakeholders to address the threat of invasive crayfish. The Invasive Crayfish Collaborative (ICC), includes 68 experts and other stakeholders from government agencies, universities, non-profit organizations, and private businesses to combine resources and expertise to address priority invasive crayfish research and outreach needs.

Invasive crayfish (also called crawdads) displace crayfish species naturally found in bodies of water ("native" species). They introduce disease, hurt fishing, and harm aquatic ecosystems. Our best hope of controlling them is to prevent their introduction to new locations.
