After maturity is reached, growth slows greatly, with males typically molting twice per year and females molting once. In Fisheries Order 227. They are dark reddish, brown and have dark, rusty spots on each side of the carapace at the base of the cephalothorax. Its further spread is of great concern since the prior areas of invasion have led to severe impacts on native flora and fauna. Towle, D.J. Capelli. Aquatic Invasions 10(2):189-198. Biological Invasions 8: 1621-1628. The expected lifespan of F. rusticus is 3-4 years. Lawton, and M. Shachak. Rusty Crayfish Resources.

Rusty crayfish were first detected in Trout Lake, Vilas County, Wisconsin, in 1979 (Lodge et al. Diel changes in resource demand: Competition and predation in species replacement among crayfishes. During mesocosm experiments, F. rusticus reduced the abundance of the native snail species Physa gyrina and Lymnaea stagnalis; when F. rusticus co-occured with Cipangopaludina chinensis (the Chinese mysterysnail), Lymnaea stagnalis was extirpated from the mesocosm (Johnson et al., 2009). Species replacements among Orconectes crayfish in northern Wisconsin lakes: the role of predation by fish. Capelli, and R.J. Houlihan. Hobbs, H.H. Mundahl, N.D. 1989. Rusty Crayfish Rusty crayfish (Orconectes rusticus) is a non-native invasive species that may have been intentionally introduced from a bait bucket release, a mercy release, or from an unintentional release such as a boat transfer.Rusty crayfish are commonly found in lakes, rivers, ponds and streams with clay, silt and gravel bottoms that contain rocks, logs or debris. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. Most of the body is tan to light brown, but each side of the carapace has a rusty brown spot. Kuhlmann , M. L. 2016. Marking. Simon, T.P. Papers of the Michigan Academy of Science, Arts and Letters 13: 257-276. So people use them as pets and then after a while they get rid of them. Their carapace usually has a pair of rusty-colored spots and claws often have black bands at their tips. Description: A medium-sized to large brownish crayfish with large claws and rusty patches on the sides of their carapace. Hein, C.L., M.J. Van der Zanden, and J.J.Magnuson. Scaling up: long term scale impacts of the invasion of lakes by the invasive rusty crayfish (Oroconectes rusticus). Rusty Crayfish (Orconectes rusticus). Welch , C. 2014. PhD dissertation, University of Notre Dame, Notre Dame, Indiana. They prefer areas that offer rocks, logs, or other debris as cover. The rusty crayfish is also commonly sold to schools and biological supply houses, leading to the potential for uninformed release into the wild (Gunderson 2008; Larson and Olden 2008; Kilian et al. 2012. Canadian Journal of Fisheries and Aquatic Science 61: 2255-2266. Rosenthal, S.K., S.S. Stevens, and D.M. Freshwater Crayfish 5: 193-209. In its native range within the Ohio River valley, F. rusticus may seasonally be exposed to water temperatures ranging from close to 0°C up to 39°C; however, it prefers water temperatures between 20 and 25°C (Mundahl and Benton 1990). Aquatic Invasions 3: 465-468. Charlebois, P.M., and G.A. It can be easily confused with other locally-native crayfish species. Lodge, D.M., and J.G. Organisms as ecosystem engineers.
