The University of the Sunshine Coast Tropical Aquaculture page covers research and industry

Aquaculture is the world's fastest-growing food-producing sector and the fastest-growing primary industry sector in the Indo-Pacific. It is also recognised as part of the solution to regional food security. Increasing global demand for aquaculture products is expected to see production for human consumption exceed that of wild fisheries by 2018 (Food and Agriculture Organization of the United Nati

ons - FAO). The estimated demand for fish across the Pacific alone will increase from 245,000 tonnes in 2010 to 605,000 tonnes in 2030, an increase of 250 per cent. To meet demand through continued, sustainable industry growth, requires overcoming numerous challenges through scientific development. These include: improving yields from existing aquaculture systems; developing new aquaculture species; and building sustainability into aquaculture practices. Much of this innovation will occur in tropical areas where aquaculture is largely underdeveloped. Tropical Aquaculture is a relatively new discipline at the University of the Sunshine Coast (USC). A professional team provides internationally-recognised expertise in:

• understanding the biology, ecology and culture requirements of target species and development of culture systems appropriate for local conditions and compatible with local lifestyles and customs;

• improving production of farmed tropical species through improved husbandry techniques and culture systems, greater understanding of nutritional requirements supporting feed development and improved feeding strategies, selective breeding and domestication of new aquaculture species;

• capacity building with regional partner institutions and specialised training of future tropical aquaculturists, industry and government leaders;

• researching and defining the socio-economic and socio-cultural aspects of tropical aquaculture and its uptake by coastal communities.

In exciting news from , a by-product from the harvest of mabé pearls, the viscera or oyster tissue, is showing promise as a horticultural .

Once separated from the valuable adductor muscle, remaining viscera are composed of mantle tissue, gills, g***d and digestive tissues which are usually discarded following harvest.

Recent research at the University of the South Pacific ( ) tested the potential of dried pulverised viscera from 𝘗𝘵𝘦𝘳𝘪𝘢 𝘱𝘦𝘯𝘨𝘶𝘪𝘯 as a novel horticultural fertiliser.

Results showed that even at low levels (0.3% of potting mix w/w) dried pearl oyster viscera enhanced growth of vegetables compared to controls, with higher inclusion levels (to 3%) supporting even further improvement.

This research, which was supported by the -funded livelihoods project, demonstrates the further utility of pearl oyster meat, as well as shells, and provides a new perspective on potential contributions of cultured pearl oysters to food systems in the Pacific.

Faiana Feáomoeata recently became the new President of the Pearl Farmers Association, a title that she is very proud to hold.

Faiana says the Association provides a vital place for local farmers to learn from each other, share ideas, and grow stronger in their business endeavours. She loves working with fellow Association members, the Ministry of Fisheries - Tonga , and / project members.

"I hope that during my time as President, I can influence local farmers to come together and be responsible in running the Vava’u Pearl Center with the highest quality products. I also hope to expose more of our beautiful, local-made products nationally and internationally to help our farmers and artisans improve their livelihoods."

Faiana started her pearl farm in 2017. Fast forward to 2026, and she is also a mabé pearl artisan and markets her own products.

Faiana is a proud mother of two, who says she has achieved a significant improvement in standard of living since becoming a mabé pearl farmer. She says that her business success also supports the local community, as she employs two young people at her farm.

Her success and encouragement have motivated several people on her island to join pearl farming. Prior to 2017, there was just one mabé pearl farm on her island, and now there are seven.

“Pearl farming really helps my community financially.” Faiana Fukofuka

According to Faiana, the future of mabé pearl farming and mabé pearl and pearl shell handicrafts looks bright, especially due to the newly-renovated store, handicrafts production workshop and mabé pearl retail centre which will help to ensure the quality of their products and better focus product marketing.

Consistent supply is also something that can now be offered since local mabé pearl farms have their own spat collector lines enabling them to sustain oyster stock, products and sales.

Faiana would like to thank Australian Centre for International Agricultural Research ( ), University of the Sunshine Coast , World Bank Pacific, and the Ministry of Fisheries - Tonga for their ongoing support for pearl farmers.

Congratulations to University of the South Pacific ( ) PhD candidate, Kelly Thomas Brown, on submission of his PhD thesis ‘𝐆𝐞𝐧𝐨𝐦𝐢𝐜 𝐢𝐧𝐬𝐢𝐠𝐡𝐭𝐬 𝐟𝐨𝐫 𝐟𝐢𝐬𝐡𝐞𝐫𝐲 𝐦𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭, 𝐫𝐞𝐬𝐭𝐨𝐜𝐤𝐢𝐧𝐠 𝐚𝐧𝐝 𝐦𝐚𝐫𝐢𝐜𝐮𝐥𝐭𝐮𝐫𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐡𝐢𝐠𝐡-𝐯𝐚𝐥𝐮𝐞 𝐬𝐞𝐚 𝐜𝐮𝐜𝐮𝐦𝐛𝐞𝐫, 𝑯𝒐𝒍𝒐𝒕𝒉𝒖𝒓𝒊𝒂 (𝑴𝒆𝒕𝒓𝒊𝒂𝒕𝒚𝒍𝒂) 𝒔𝒄𝒂𝒃𝒓𝒂’.

Based on four inter-related genomic studies, Kelly’s research addressed critical knowledge gaps in sandfish population genetic structure, connectivity, taxonomy, and hatchery management, to help inform sustainable fishery management and effective conservation of this species.

Kelly was supervised by researchers, Dr Monal Lal and Prof Paul Southgate, and researcher, Dr Brian Stockwell.

Kelly’s research was supported by an John Allwright Fellowship ( ) Returnee Award and broader ACIAR research into increasing technical skills and supporting community-based sea cucumber production in the region. It is one of several exchange arrangements facilitating collaborative research and capacity building in the Pacific.
