This pamphlet folds out into a poster and describes four regulated crayfish (rusty crayfish, marbled crayfish, Australian crayfish, and red swamp crayfish). It includes detailed illustrations and descriptions of invasive crayfish anatomy to assist with identification. It is written for a general audience, but is most applicable to aquarium retailers and consumers in the Great Lakes region.
It was funded in part by the Michigan Invasive Species Grant Program and by the United States Environmental Protection Agency through the Great Lakes Restoration Initiative.
