Faxonius rusticus
Taxonomic Group: Crustaceans-Crayfish
Common name: RUSTY CRAYFISH

Overview:

Orconectes rusticus is commonly known as the Rusty Crayfish. It is native to the Ohio River Basin in the Midwest United States, but its range has expanded rapidly during the past 20 years and it is now introduced to at least 20 US states and two Canadian provinces. It is widespread in the Hudson River estuary, New York and the Chesapeake Bay watershed. It inhabits streams, ponds and lakes in a variety of habitats, including rocky, muddy, and vegetated areas. In some regions, it is found in brackish water up to a salinity of 15 PSU. It has had negative ecological impacts in lakes and streams where it has ben introduced, by damaging aquatic vegetation, competing with native crayfishes, and preying on native snails.
