Potato Cod
Monitoring of the potato cod population and human activities at the Cod Hole continued up to January 2000 with the co-operation of Lizard Island Charters. The main attraction of this internationally-famous dive site is the resident potato cod population. However, the number of potato cod observed at the Cod Hole has been decreasing since the survey began in 1992. In the first 12 months of the survey, a mean of 12 and a maximum of 26 potato cod were seen per dive, but by the year to April 1997, the mean was 6 and the maximum was 13 potato cod per dive. It is not known whether the fish have died, moved elsewhere, or are still present in the area but fewer are seen at any one time. Neither is it known whether the decline is being caused or exacerbated by the level of human usage of the area. A report has been submitted to the Great Barrier Reef Marine Park Authority. Monitoring continued with the cooperation of P&O Australian Resorts when the Lizard Island Resort reopened in July 2000. Relevant links
