Editing Murray cod (section)

==Range==
The Murray cod is named after the [[Murray River]], part of the Murray-Darling basin in eastern Australia, Australia's largest and most important river system, draining around 14% of the continent.<ref name=CadwalladerBackhouse1983/><ref name=mdbcstats>{{Cite web |title=Basin Statistics

Consequently, Murray cod inhabit a remarkably wide variety of habitats, from cool, clear, fast-flowing streams with riffle-and-pool structure and rocky [[Substrate (marine biology)|substrates]] in upland areas to large, slow flowing, meandering rivers in the extensive alluvial lowland reaches of the Murray-Darling basin.<ref name="CadwalladerBackhouse1983"/><ref name="McDowall1996"/>

Murray cod have died out in many of their upland habitats, particularly in the southern Murray-Darling basin, due to a combination of [[overfishing]], [[siltation]], dams and [[weir]]s blocking migration, pollution from [[arsenic]]-based sheep-dips, [[mining]], and in some cases, introduced [[trout]] stockings, which causes competition between juvenile Murray cod and introduced [[trout]] species.<ref name=Rowland2005/><ref name="Rowland2020">

Murray Cod have also been introduced into other [[drainage basin]]s, such as the Cooper Basin in Queensland.<ref name="Unmack">{{cite web |last1=Unmack |first1=Peter J. |title=Macullochella peelii peelii (Mitchell 1838) |url=https://www.desertfishes.org/australia/fish/maccpeel.html |website=Desert Fishes of Australia |access-date=9 May 2022}}
