==Age==
Murray cod are very long-lived, which is characteristic of many freshwater native fish in Australia.<ref name=nfacod/> Longevity is a survival strategy in variable Australian environment to ensure that most adults participate in at least one exceptional [[Spawn (biology)|spawning]] and recruitment event, which are often linked to unusually wet [[La Niña]] years and may only occur every one or two decades.<ref name=nfacod/> Murray cod are the most long-lived freshwater native fish in Australia.<ref name=CadwalladerBackhouse1983/> The oldest Murray cod aged yet was 48 years of age,<ref name="AndersonEtAl1992">{{cite journal  | last = Anderson  | first = J.
