About the research project

Atlantic salmon aquaculture is a key industry in Tasmania, providing over 80,000 T of production per annum, valued at more than $1 billion. Amoebic gill disease (AGD) is the main parasitic disease affecting fish in sea pens and is controlled by freshwater bathing in specialised 'wellboats'. Fish are held in the freshwater well for a few hours before being transferred back to their pen while the water is retained on the wellboat. Water is generally re-used for 3-4 groups of fish and managed to key water quality parameters. Currently, it is unknown whether freshwater reuse constitutes an increased risk of viable pathogen exposure as salmon cohorts are sequentially passed through the treatment system.


The PhD candidate will explore the dynamics of potential pathogens in wellboat systems, and their distribution on salmon farms, using a range of culture-based and cutting-edge molecular techniques such as DNA and RNA metagenomics. In doing so, the candidate will also develop tools aimed at supporting sustainable and effective bathwater management.
The PhD candidate will have the opportunity to work within a multidisciplinary team. The project will require a fieldwork component, allowing the candidate to gain a variety of hands-on skills. The candidate is expected to communicate within a team and with external partners, contribute to existing scientific literature, and report ideas and findings efficiently both in written and oral forms.


This PhD project is prestigious and in honour of Dr Harry King who was a widely respected aquaculture biologist and left an indelible mark on the Atlantic salmon industry as a research scientist and farm manager. A fully funded scholarship by the "Dr Harry King Memorial Scholarship" will provide the opportunity to begin a career in environmental pathobiology and to continue Harry's work to apply impactful solutions to aquaculture production. The successful applicant will be embedded in an emerging salmon research team of academic and industry leaders inclusive of IMAS, CSIRO, Tassal, Huon Aquaculture, and BioMar.

The supervisory and research advisory team will include:
Dr Gianluca Amoroso - UTAS Research fellow in Aquaculture - Salmon Production
Dr Mark Adams - UTAS Senior Research Fellow in Aquaculture - AGD expert
Dr Richard Taylor - CSIRO Senior Experimental Scientist - AGD expert
Dr Pascal Craw - CSIRO Research Scientist - Microbial genomics
Dr Laura Baseggio - CSIRO Postdoctoral Research Fellow - Microbial genomics
Dr Jasmine Knowles - Huon Veterinary and Group Fish Health Manager
