- Richmond River cod
The Richmond River cod is a form of "
Maccullochella " cod, now believed to have beeneastern freshwater cod , "Maccullochella ikei", that occurred naturally in theRichmond River system, an east coast river system in north-eastNew South Wales ,Australia .Eastern freshwater cod in turn are a species of "Maccullochella" cod found in east coast drainages and originating from
Murray cod , "Maccullochella peelii peelii", that crossed theGreat Dividing Range and entered east coast drainages from one or more naturalriver capture events.Richmond River cod are unfortunately extinct, from overfishing, habitat destruction including gross siltation, and whole-of-catchment scale bushfires and ash fish kills in the 1930s.
The Richmond River system has now been restocked with small numbers of eastern freshwater cod from the Clarence River system, but these appear to have been insufficient to re-establish populations; there is no evidence of these stocked fish reproducing as yet.
