Aquaculture is the world’s fastest-growing food-producing sector and the fastest-growing primary industry sector in the Indo-Pacific. It is recognised as part of the solution to regional food security, but also has important roles in providing community livelihood opportunities, in supporting conservation efforts including restocking, habitat regeneration and marine protected areas, in reducing fishing pressure on coastal and freshwater resources, in the captive breeding of desirable and rare aquarium species, and in bringing economic benefits through domestic sales and exports.
The Aquaculture-based livelihoods research team combines science, economics and social science to develop industries and programs that are profitable, sustainable and culturally appropriate. A key aspect is institutional capacity building in partner agencies, thus supporting long-term development.

Recent research projects
Developing pearl industry based livelihoods in the western Pacific
This project aims to maximise engagement of remote coastal communities in activities that can generate livelihood supporting and income generating opportunities for individuals, families and community groups in Fiji, Tonga and PNG. These activities include collection of juvenile oysters (‘spat’) for sale to pearl farms or for local utilisation, mabè pearl production, and the use of mabé pearls and pearl shell to produce retail-quality jewellery and handicrafts. These activities provide important socio-economic impacts with particular benefit to women and youth.

Half-pearl industry development in Tonga and Vietnam
This project supports further development of community-based pearl farming in Tonga and investigates similar sector potential in Vietnam. Half-pearl (mabé) production and associated handicrafts industries are expanding and provide impressive livelihood benefits in Tonga. This project provides support to maintain this momentum as a basis for further sustainable development of the sector. Pearl oysters used for mabé pearl production are also found in Vietnam, but are not yet utilised for mabé or handicraft production despite a considerable tourist market. This project investigates the potential for successful transfer of culture methods developed in Tonga to Vietnam as a kick-start to sector development.

Improved understanding of sandfish biology and culture supporting community mariculture in the Indo-Pacific
This research theme includes research across a number of projects and countries including Vietnam, Philippines, PNG and Fiji with broad regional objectives. Research in Fiji is conducted collaboratively with the University of The South Pacific (USP) and the Ministry of Fisheries and focuses on elucidating the genetic make-up of sandfish stocks in Fiji and the Pacific, with broader collaborative links to similar research in SE Asia. Outputs will provide a broad understanding of population genetics of sandfish in the region to inform fishery management policy, and mariculture activities such as hatchery production, broodstock management and translocation of hatchery produced juveniles for field culture.
