Editing Murray cod (section)

==Diet==
The Murray cod is the apex aquatic predator in the rivers of the Murray-Darling basin,<ref name="FOA" /> and will eat almost anything smaller than itself, including finned fishes such as smaller Murray cod, [[golden perch]], [[Bidyanus bidyanus|silver perch]], [[bony bream]], [[eel-tailed catfish]], [[western carp gudgeon]], and [[Australian smelt]] and introduced fish such as [[carp]], [[goldfish]], and [[European perch|redfin (English perch)]], as well as [[crustacean]]s such as [[common yabby|yabbies]], [[Atyidae|freshwater shrimp]], and [[Murray crayfish]]. Fish are eaten when abundant by mature Murray cod in lowland river and impoundment habitats<ref name=Ebner2006>, but crustaceans (shrimp, yabbies, crayfish) are likely the preferred diet under 'natural' river conditions, and mussels were an important food source, at least in the past.

</ref> but crustaceans tend to dominate the diet under natural conditions, and freshwater mussels were commonly eaten in the past.<ref name=":1" /><ref name=":2" /> Murray cod have also been known to eat [[duck]]s, [[cormorant]]s, [[Chelidae|freshwater turtle]]s, [[Physignathus lesueurii|water dragon]]s, [[snake]]s, [[mice]], and [[frog]]s. The observations of the recreational fishermen fishing for Murray cod with surface lures at night reveal that the popular description of Murray cod as a [[Demersal zone|demersal]] [[ambush predator]] is only partially correct. While this behaviour is typical during the day, at night, Murray cod are active [[Pelagic zone|pelagic]] predators, venturing into shallow waters and frequently taking prey from the surface.<ref name=schultz2006>
