About the Invasive Crayfish Collaborative
The Invasive Crayfish Collaborative (ICC) brings industry, science, and land management stakeholders together to improve the management of invasive crayfish in the Great Lakes region. It is convened and facilitated by Illinois-Indiana Sea Grant and the Illinois Natural History Survey with funding from the Great Lakes Restoration Initiative.

Environmental regulators have classified a dozen aquatic plants, fish and invertebrates as prohibited invasive species in Minnesota- one being the invasive marbled crayfish (Procambarus virginalis).
Research reveals hope for managing invasive red swamp crayfish
Originally from the southeastern U.S., the red swamp crayfish (Procambarus clarkii) has become an unwelcomed world traveler. Here in the U.S., they are commonly spread by unsuspecting aquarium-hobbyists or biology teachers releasing the unwanted pet into their backyard ponds and rivers. Despite the destructive nature of this species, the U.S. Fish and Wildlife Service haven’t given up the fight.
Scientists work to stop self-cloning crayfish in Burlington, Ont., pond after 1st detection in Canada
The invasive marbled crayfish was discovered last summer in Burlington, and a group of experts have been working to stop the species from spreading.
Signal crayfish confirmed in Minnesota
