Open encyclopedia reference
The eastern freshwater cod (Maccullochella ikei), also known as the eastern cod or Clarence River cod, is a large predatory freshwater fish of the genus Maccullochella and the family Percichthyidae, that occur in the coastal Clarence River system of north-eastern New South Wales. Eastern freshwater cod are closely related to the Murray cod of the Murray-Darling River system, and are considered an icon of the Clarence River system.
A long-lived, slow-growing species, eastern freshwater cod are threatened by poaching [i.e. illegal take], habitat degradation, catastrophic natural events such as bushfires, and inbreeding from low genetic diversity. They are currently classified as endangered and protected by law from human exploitation of any kind.
