Project 6.2 'Drivers of juvenile shark biodiversity and abundance in inshore ecosystems of the Great Barrier Reef'

Sharks play an important role in marine ecosystems but are facing increasing pressure from fishing and other anthropogenic factors. Along the Queensland coast inshore waters play an important role as nursery areas for sharks. However, the same inshore waters are also most prone to fisheries exploitation and effects of freshwater discharge from coastal streams and rivers. This project will examine the importance of different types of inshore habitat (protected bay vs. open coastline) and marine park zoning (open and closed to fishing), and how environmental factors such as freshwater discharge from rivers effect how these nursery areas function. The project has two broad objectives:

• Investigate the spatial and temporal changes in the biodiversity and abundance of sharks in inshore nursery areas along the central coast of the Great Barrier Reef; and
• Determine the effect of environmental drivers on inshore shark biodiversity along the central coast of the Great Barrier Reef.

Results from the project will be used to improve the information available to fisheries and marine park managers on the relative importance of inshore habitats, the role of areas closed to fishing, and the sustainability of inshore shark populations.

Specific objectives and intended outputs of this Project are detailed in the NERP TE Hub Multi-Year Research Plan.
