The crayfish website provides access to the list of crayfish in Canada and the United States as determined by the 2007 American Fisheries Society (AFS) Endangered Species Committee (ESC) on Crayfishes. About 48% of the crayfish species in freshwater habitats are in some level of imperilment. At this website, one can view lists of crayfishes by freshwater ecoregion, by state or province boundary, and plot distributions of crayfishes by ecoregions or political boundaries. Both native and presumed introduced ranges are displayed. Lists can be downloaded for use in reports or analyses. There are also links to the Fisheries publication and other resources.
