Program Overview

This subprogram focuses on conducting ecological studies on hard and soft substrate communities. In particular, research is conducted on the population and community organisation of bottom dwelling fauna, and on trophic linkages between benthos and demersal fish.

The subprogram undertakes benthic research on coastal, shelf and deep-sea environments throughout southern Australia. A large component of this research is directed towards the selection and ongoing assessment of State and Commonwealth Government marine reserves (including the Great Australian Bight Marine Park).    

The subprogram also collaborates with the Fisheries Program on conducting research and providing scientific advice on the sustainable management of South Australia’s Giant Crab, Blue Crab and Prawn Fisheries. A key focus of this research is on understanding the population dynamics of the fisheries and ways to improve harvesting strategies. The subprogram further undertakes research on the ecological impact of these fisheries.

Subprogram staff have strong associations with leading national and international researchers and have built successful multi-disciplinary proposals to investigate water circulation patterns in the Southern Ocean and their influence on benthic productivity.  These collaborations enhance the delivery of high quality benthic research for the region.
