Flamingo Land crayfish conservation project produces over 200 young
Flamingo Land’s crayfish hatchery has raised over 200 endangered white-clawed crayfish for release in 2026. The project aims to boost survival rates from 5% to 95% through expert care.
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.
