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.

The Five-Year Strategic Plan to Advance the Management of Invasive Crayfish
This plan, developed with ICC member input, will guide the work of the ICC for the next five years (2025-2029). It aims to foster collaborations across different jurisdictions and disciplines, connect members with stakeholders, and provide members with the necessary resources to reach our mission of reducing the impacts of invasive crayfish in the Great Lakes region.

Participate in Graduate Research on Crayfish Use in Classrooms
Purdue master's student Izzy Paulsen is conducting research on the motivations of teachers using live crayfish in classrooms. She is interviewing science teachers (grades 3-12) who have used live crayfish in their classes. To participate in these interviews, please complete the interest form found in the link above.
Crayfish map gives conservation a helping claw
Conservation scientists and invasive species managers share a key need: to know where target crayfish are. Researchers at the West University of Timișoara, Romania (WUT) and the University of Illinois Urbana-Champaign have created the first searchable global crayfish atlas, World of Crayfish, with data on 427 crayfish taxa and over 100,000 observations.
News release: Minnesota DNR classifies 13 invasive plants, animals as prohibited
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.
