After completing a Bachelors in Marine Science with the Institute for Marine and Antarctic Studies (IMAS), University of Tasmania (UTAS), I embarked on an exciting honours project which investigated the importance of net colour in gillnet fishing practices in order to minimise the capture of bycatch species in gillnets. The field trials conducted within the facilities of the Melbourne Zoo assessed how little penguins respond to different coloured monofilament lines. This project was conducted with IMAS, UTAS and Zoos Victoria under the guidance of Associate Prof. Mary-Anne Lea, Prof. Mark Hindell and Dr. Barry Baker, funded by the Australian Antarctic Division under the Agreement on the Conservation of Albatrosses and Petrels (ACAP).

For my PhD, I am investigating the Portunid crab fisheries in New South Wales.

My major research objectives include:

  • To investigate temporal and spatial patterns in the settlement and habitat preference of juvenile blue swimmer crabs
  • To determine if these characteristics are linked to environmental variables and nutrient availability
  • To inform managers of strategies in the effective management of crab fisheries including modelling and fisheries enhancement

This project is in collaboration with the Port Stephens Fisheries Institute (Department of Primary Industries), supervised by Prof. Iain Suthers and Dr. Matt Taylor and is funded by the NSW Recreational Saltwater Fishing Trust and the Fisheries R&D Corporation.
