Great Barrier Reef Marine Park Authority :: Interaction of fishing with coral reefs

Interaction of fishing with coral reefs

Management Concern: Moderate    

Adequacy of Information: Good

Summary extracts from Outlook Report 2009

  • Coral reef habitats are likely to be declining, more so in inshore areas, but the trends are difficult to interpret.
  • Available evidence indicates that the overall status of coral reefs on the GBR is relatively good, but is likely to be declining slightly, especially in inshore areas.  However, the picture is not simple or clear cut, with reefs in different regions showing enormous differences in trends, including both increases and declines. This is because coral reefs are naturally dynamic habitats, with cycles of disturbance and recovery. The challenge is to detect whether there are long-term trends hidden within natural cycles.
  • There is limited information about many  targeted species and of the survival success of discarded species resulting in a poor understanding of the broad scale and cumulative ecosystem effects of fishing.
  • Illegal fishing is a threat to the Great Barrier Reef ecosystem. Incidents detected include incursion of foreign fishing vessels, fishing in zones closed to fishing, and use of fishing equipment or methods in zones where they are not permitted.
  • Further information is needed on the resilience of coral reef habitats and cumulative impacts of climate change and commercial and non-commercial use.
