Job Title

Overview The Research Institute for Northern Agriculture is seeking applicants for a unique opportunity to work with an Indigenous enterprise in a remote Indigenous community developing a blue economy to safeguard the future of one of Australias largest islands. The project will develop production methods for a herbivorous marine fish, the goldlined rabbitfish, to enable a more sustainable and climate-resilient future for Australian finfish aquaculture. The enhanced collaboration between Charles Darwin University, Groote Aqua Aboriginal Corporation and the CSIRO, working alongside Anindilyakwa Traditional Owners, will yield a better understanding of goldlined rabbitfish propagation techniques and nutritional requirements. This will ultimately improve Groote Aquas production efficiencies and, consequently, improve food security, revenues and employment prospects on Groote Eylandt, which are key milestones for the Aboriginal Corporation to prepare for and facilitate the transition from six decades of mining to self-sufficiency. Scholarship and financial support: A tax-exempt stipend commencing at $48,000 per year for four years, with annual increases over the four-year period (available to Australian citizens or permanent residents, and New Zealand citizens only) University relocation allowance may be available Generous project expense and development package of $13,000/year About the project: Australian finfish aquaculture involves carnivorous fishes that require a wild-caught fish component in their diet. Wild fishery landings plateaued three decades ago and thus the increasing demand for and use of wild-sourced ingredients for farming fish is unsustainable, particularly with respect to food security. Rabbitfishes are marine herbivores, with some showing promising aquaculture potential. One of the largest rabbitfish species is the goldlined rabbitfish (GLR) Siganus lineatus, a popular fish in the South Pacific, which combines flexible nutritional requirements, high tolerance to variable water quality, and strong grazing capacity for fouling control in ponds, sea cages, and tanks, while also being an excellent food fish. Groote Aqua Aboriginal Corporation (GAAC) is investigating the potential of including this species within its integrated low trophic aquaculture program to improve local food security and to develop a blue economy for a sustainable post-mining future. Over the past year, GAAC has established and maintained broodstock (monthly spawns) and conducted multiple successful larval rearing trials of GLR. This has enabled production of hatchery-bred juveniles, which have already been deployed in several trials. At the production facility, GLR were stocked into tanks deliberately allowed to develop significant macroalgal growth and successfully reduced algal biomass through active grazing, effectively cleaning the tanks. More recently, juvenile GLR were also supplied to the Darwin Waterfront to assist with macroalgae control. While this initiative is still in its early stages, the fish are grazing actively and showing good growth performance to date. In this project, GAAC will work with CDU, the CSIRO and the successful candidate to develop and optimise hatchery and nursery production protocols for GLR so they can be introduced to sea cucumber production ponds to control macroalgae growth. In addition to being a cleaner fish, GLR also has great table fish potential as sustainable white flesh fish that does not require wild-caught fish in its diet. The benefits of growing this fish are therefore twofold: 1) reduced labour cost of cleaning ponds/tanks and 2) additional healthy protein produced locally. As per the Darwin Waterfront, GLR could also provide a solution beyond Groote Eylandt, such as for enclosed marinas and marine fish farms dealing with macroalgae outbreaks that are costly to remove. The project aims at enabling the assessment of the potential of GLR to play a key role for an Aboriginal community in their economic, environmental and social transition from a mining era to a blue future.

We innovate, embrace new ideas, and act with courage and kindness. Were about what we can give to the world rather than what we take, and we believe in the transformative power of education. We work hard to make sure every member of our university community feels that they truly belong. Understanding that it is through our focus on our people and leveraging our differences that will make CDU the most connected university in Australia, we are striving to ensure that our culture and our community are inclusive of all our staff, students and visitors. We are committed to maintaining a culture where everyone feels respected, safe, encouraged to speak up and supported in achieving their professional goals. You make CDU. And we want you to be exactly who you are. #J-18808-Ljbffr
