New Book Highlights Crayfish Diversity and Importance
Biologist and crayfish expert Zackary Graham’s newly published book, Crayfish, Crawfish, Crawdad: The Biology and Conservation of North America's Favorite Crustaceans, takes readers on a journey from the coalfields of Central Appalachia to the spring-fed water of Northern California, and even in roadside ditches in between. Graham discusses crayfish habitats, anatomy, and coloration. To learn more and read an excerpt, visit the book page. Free electronic exam copies are also available to instructors. Visit the For Educators page for details.
TNC and partners map Lake Michigan spawning reefs and species that use them
The Nature Conservancy (TNC), in partnership with Michigan DNR, Grand Traverse Band of Ottawa and Chippewa Indians, and USGS, completed a multi-year study of spawning reefs in northern Lake Michigan to inform future reef restoration efforts. The maps detail the size and physical characteristics of the reefs, the fish that use them, and other species observed, including invasive species like quagga mussels, round gobies, and rusty crayfish.
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.
