About the research project
This project will focus on defining optimum protein quality by determining key essential amino acid requirements for juvenile topical and slipper lobsters. Emphasis will be placed on understanding the importance of between meal changes in tissue amino acid supply, balance and fluxes into growth or metabolism. The research will combine established and cutting-edge methods to understand amino acid metabolism at multiple levels and specifically related to how well amino acid requirements are being met or not met. Classic factorial modelling of amino acid requirements will establish the base experimental approach. Advanced respirometry, combining oxygen consumption with carbon dioxide and nitrogenous excretion, will determine changes in substrate utilization within 24-h cycles and incorporate between meal changes in amino acid supply to tissues. Protein turnover will be measured because it underlies growth, is strongly influenced by dietary protein quality (amino acid balance) and has high energy costs. Stable isotope tracking to the level of specific amino acids will be developed and provide further detail on metabolic pathways and specific amino acid retention efficiencies (e.g. Barreto-Curiel et al 2019). Targeted transcriptomics or proteomics may then be used to understand how gene regulation relates to differences in protein turnover and amino acid fluxes. The research will ultimately help explain mechanisms that underpin dietary differences in whole-animal growth efficiency and provide a detailed basis for feed formulation.
The successful applicant will receive a scholarship which provides:
- a living allowance stipend of $28,597 per annum (2021 rate, indexed annually) for 3.5 years
- a relocation allowance of up to $2,000
- a tuition fees offset covering the cost of tuition fees for up to four years (domestic applicants only)
International applicants will receive a University of Tasmania Fees Offset for up to four years.
The project is open to domestic (Australia and New Zealand) and international applicants who are already in Australia (onshore) at the time of submitting their application.
Due to current Australian COVID-19 travel restrictions the University cannot accept applications from International applicants who are currently overseas.
