  • Illinois-Indiana Sea Grant College Program.
    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.
Native To:
Ohio River drainage (Wilson et al. 2004)
Date of U.S. Introduction:
First discovered outside of its native range in Wisconsin in the 1960s (DiDonato and Lodge 1993)
Means of Introduction:
Probably through bait bucket releases (DiDonato and Lodge 1993)
Impact:
Competes with native crayfish species and causes a decline in native species abundance (DiDonato and Lodge 1993)
Current U.S. Distribution:
Great Lakes Region, New England, and Eastern U.S.

The Colorado Division of Wildlife is monitoring the state's waters for the introduction of an aggressive invasive species, the rusty crayfish. Rusty crayfish were found for the first time in Colorado during routine sampling operations in 2009 in the Yampa River drainage between Steamboat Springs and the town of Yampa. Because of their larger size and more aggressive nature, rusty crayfish can impact fish populations by consuming small fish and fish eggs, and negatively impact fish and spread unwanted aquatic plants by aggressively harvesting underwater plant beds. Learn more how to identify the rusty crayfish, how to stop the spread and how to report sightings.
