Research Interests

Research Interests I am a “true believer” in the value of fisheries to society, particularly the social and economic benefits that they provide to rural and regional communities. To continue to provide such benefits, it is essential that fisheries have a long term future. Given the demise of fisheries globally I have explored new methods and techniques to estimate key fisheries parameters that can be used to ensure sustainability. With the adoption of Ecological Sustainable Development (ESD) and Ecosystem Based Fisheries Management (EBFM) I am also evaluating methods for understanding the impacts of fishing on the ecosystem. Fisheries are dependent on healthy and productive ecosystems and understanding the drivers for productivity and resilience of marine ecosystems is core to ensuring productive and sustainable fisheries. Currently I lead TAFI’s climate change theme and am extending my research into understanding the impacts of climate change on fisheries.
I am also a strong supporter for the need to underpin fisheries assessments with a triple bottom line approach and actively collaborate with colleagues in the disciplines of economics, social and governance issues in fisheries.
Research Areas • Climate change impacts and adaption on marine fisheries and ecosystems • Integrating biophysical, social, economic and governance issues in managing marine systems. • Developing metrics for monitoring and assessing fisheries including the effects of fishing.
