Rusty crayfish2/20/2023 ![]() ![]() In Atlantic drainages, the distribution of Faxonius rusticus has also been spotty. North American Invasion History: Invasion History on the West Coast: The distribution of this crayfish in the Great Lakes region, as mapped by Hobbs and Jass (1988) is spotty and suggests that dispersal to inland lakes and streams by bait and other means has been more important than movement through the open waters of the Great Lakes. rusticus was established on the Bruce Peninsula between Lakes Erie and Ontario (Corey 1988). It was first recorded in Lake-of-the-Woods, Ontario, in 1964, and on the northwest shore of Lake Superior in 1985, and is now widespread (Momot 1992 Momot 1996). It is found in many of the streams on the southwest (Wisconsin) shore of Lake Superior (Hobbs and Jass 1988). 2002 USGS Nonindigenous Aquatic Species Program 2017). rusticus may have been present in the low country at the western end of Lake Erie in the early 19th century, but did not become widespread around the lake until the 1960's (Perry et al. rusticus has invaded streams in Tennessee, Missouri, Indiana, Iowa, and Minnesota (Hobbs and Jass 1988). Elsewhere in the Mississippi drainage, O. In Wisconsin, it was not recorded in 1932, but it became widespread by the 1960's. ![]() In the Ohio Basin, it expanded into the Kanwaha River and tributaries in southwestern West Virginia by 1978 (Jezerinac et al. It was first recorded from Illinois in 1973, and is now widespread in the Illinois River system in the northern part of the state (Taylor and Redmer 1996). rusticus has drastically expanded its range since it was first introduced in 1932 (Hobbs et al. ![]() Its range has rapidly expanded due to a mixture of natural dispersal, aggressive displacement of other species, and human introductions (Hobbs and Jass 1988 Hobbs et al. Faxonus rusticus has been widely introduced with bait, and probably also from the release of laboratory animals. Introductions are concentrated in the Northeast and Midwest, but populations are known from New Mexico, Colorado, Nevada, and Oregon (Hobbs and Jass 1988 Taylor et al. 1996 Taylor and Redmer 1996 USGS Nonindigenous Aquatic Species Program 2017). It has been introduced to at least 20 US states, and Ontario and New Brunswick in Canada (Taylor et al. First Non-native North American Tidal Record: 1996 First Non-native West Coast Tidal Record: First Non-native East/Gulf Coast Tidal Record: 1996įaxonius rusticus is native to the Ohio drainage in Ohio, Indiana, and Kentucky, with populations extending into West Virginia, Tennessee, and possibly the western end of the Lake Erie basin. ![]()
