Crayfish dumped at PetSmart adopted by Animal Care employee
Indianapolis Animal Care Services recently rescued an abandoned crayfish at a local pet store alongside other small animals. Thanks to quick action, the crayfish now has a safe new home, highlighting the shelter’s commitment to all species in need.
Managing the arrival and spread of aquatic invasive species
Researchers at Loyola University Chicago’s Keller Lab are using machine learning tools to predict the spread of invasive crayfish species under climate change scenarios. Their recent study highlights how climate shifts may expand habitats for harmful species.
Red swamp crayfish invasion in Bakersfield, CA
After recent heavy rains, invasive red swamp crayfish have been emerging out of the Kern River bed and venturing into parking lots and streets along the Truxtun Extension in Bakersfield, California.
This selection of invasive crayfish information is collected by the Invasive Crayfish Collaborative, a program convened and facilitated by Illinois-Indiana Sea Grant and the Illinois Natural History Survey with funding from the Great Lakes Restoration Initiative.
