The above factors, which have in the past led to the extinction of the Richmond River cod and the Brisbane River cod and the endangerment of the Mary River cod, have reduced the eastern freshwater cod from an abundant fish found in all parts of the Clarence River system to an endangered fish absent from most parts of it. It survives only in limited, remote parts of the Nymboida/Mann and Guy Fawkes/Sara sections. The latter population is now at risk of severe inbreeding depression and is in need of "genetic rescue" via translocation of genetically differing fish from the former, more diverse population. Currently there are no management plans to undertake such translocations.
