Cherax destructor
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cherax destructor faces severe population declines primarily due to habitat degradation from agricultural runoff, urban development, and water extraction in its native Murray-Darling Basin. Competition and hybridization with introduced crayfish species, particularly the invasive yabby populations, further threaten genetic integrity of remaining wild populations. Water quality deterioration from increased salinity and pollution has rendered many historical habitats unsuitable for this species.
Habitat
Cherax destructor inhabits slow-flowing rivers, billabongs, and wetlands throughout the Murray-Darling Basin in southeastern Australia. The species prefers shallow freshwater environments with muddy or sandy substrates and abundant aquatic vegetation for shelter and foraging.
