NERP TE Project 8.2 Do no-take marine reserves contribute to biodiversity and fishery sustainability? Assessing the effects of management zoning on inshore reefs of the Great Barrier Reef Marine Park (JCU)

Brief description

This project is providing a direct assessment of the ecological effects of multiple-use zoning on inshore reefs of the GBRMP. Underwater visual census (UVC) monitoring of fish and benthic communities is being carried out at 50 no-take marine reserve (green zone) sites and at 50 sites that have remained open to fishing within the Palm, Magnetic, Whitsunday and Keppel Island groups. Long-term monitoring surveys are providing information on:

1. The effects of no-take marine reserves on populations of both species that are fished and other non-fished species.

2. Variations in structure of fish communities due to the reserves and natural disturbances.

3. Structure and dynamics of marine species on the sea bed.

4. Coral health, bleaching, incidence and severity of coral disease and coral predators.

5. Temporal monitoring of the relative number of fishing lines recorded at each site will be used to assess the distribution of fishing effort and provide information on the levels of non-compliance with zoning regulations.
