Murray River CrayKeith A. Crandall
DistributionThe species occurs in the Murray River throughout most of its length and major tributaries in Victoria (including the Goulburn, Yea, Murrundindi, Jamieson, Howqua, Ovens and Mitta Mitta Rivers) and New South Wales (including the Murrumbidgee, Cotter and Macquarie Rivers). The range extends over 800 km east-west. The most northerly known site of the species is near Kandos 160 km west of Newcastle, NSW. Presumably the creek flows into the Cudgegong and thence Macquarie and Darling Rivers. This site indicates a north-south range of approximately 450 km.
HabitatEuastacus armatus inhabits large and small streams in a variety of habitats including cleared pasture and dry and wet sclerophyll forests (vegetation usually densest along upper reaches of streams) at altitudes from close to sea level to over 700m a.s.l.
Conservation StatusLow elevations may be depopulated with possible extinction of the species in South Australia (Kaires, 1980; Zeidler, 1982).
