The Shasta Crayfish has been in decline and under assault for decades from the pervasive, nonnative, invasive Signal Crayfish (Pacifastacus leniusculus), which not only outcompetes it for food and habitat but renders Shasta Crayfish females largely infertile through interbreeding. This region supports a limited crayfish fauna of seven common species. This crayfish inhabits permanent streams, lakes and ponds that have rocky substrate and logs or debris as cover. Contact the Queensland Crayfish Farmers Association for information about redclaw aquaculture in Queensland. 5 Crayfish Headwater Ark Sites established 5 Habitat schemes with 1.5 km habitat enhanced . The River Wansbeck is one of the last native crayfish strongholds in the country. Procambarus acutus will burrow during dry summer and fall seasons (Taylor and Schuster 2004). The carapace is not separated at its middle by a space (areola). Habitat suitable for signal crayfish includes both still and slow-flowing freshwater environments, including rivers, streams, reservoirs and canals. PANAMA CITY — Bay County’s project to widen Jenks Avenue will include restoring 17 acres of Panama City’s crayfish habitat. All of the proposed critical habitat units/subunits for the Big Sandy crayfish and two subunits of critical habitat for the Guyandotte River crayfish are occupied year-round by these species. The white-clawed crayfish Austropotamobius pallipes lives in a diverse variety of clean aquatic habitats but especially favours hard-water streams and rivers.

Riparian features such as vegetated margins, areas of overhanging vegetation or tree root systems and undercut banks provide habitat for fish, crayfish and a number of other invertebrate species. With the purpose of determining how white clawed crayfish respond to habitat and spatial variables, this study correlated white clawed crayfish distribution over a 35 km length of the River Wansbeck, Northumberland, to physical variables at three-spatial scales. Spiny-cheek crayfish can carry the crayfish plague and have a considerable impact on other freshwater animals. The white-clawed crayfish is also much smaller in size, growing to a maximum of 12 centimetres.
