The Ministry of Fisheries has stepped up its pearl oyster farming programme in Bua, sending a specialised Pearl Team to Nasau Village, Navakasiga for a week-long operation that retrieved and redeployed juvenile oysters despite environmental challenges. The latest field visit, officials said, underlines the ministry’s ongoing push to expand sustainable aquaculture and rural livelihoods on Vanua Levu.
During the visit the team recovered four spat collector lines that were deployed last year. While total recruitment was lower than in previous seasons, the exercise produced 405 healthy juvenile melamela oyster spats. Technicians drilled the young oysters, strung them into ear‑hanged chaplets and transferred the chaplets onto ocean mainlines for longer‑term grow‑out and monitoring.
Ministry staff worked side‑by‑side with Nasau villagers and local youth groups throughout the operation, combining hands‑on training with the practical tasks of cleaning, drilling and transferring spat. The ministry acknowledged the community’s cooperation and described the collaboration as an important step in building local capacity for pearl cultivation and broader community-led aquaculture enterprises.
The fieldwork was not without difficulty. Teams reported substantial biofouling on collector lines and other environmental pressures that hampered spat collection and retrieval. Biofouling — the build‑up of barnacles, algae and other organisms on gear — can reduce recruitment success and increase labour for maintenance, meaning that lower spat numbers this season are at least partly attributable to these conditions, officials said.
This deployment forms the latest phase in a wider national effort to revive coastal economies through sustainable pearl aquaculture. It follows earlier Ministry‑led activities and partner projects on Vanua Levu and beyond, which have included community training workshops under the Aqua Pearl initiative and previous implantation milestones elsewhere in the country. Together, those efforts aim to diversify marine livelihoods, boost local incomes and build the technical know‑how needed for a viable pearl sector.
For Bua, the recent operation is significant because it converts last year’s collector deployments into a new cohort of grow‑out oysters and advances local ownership of the farming process. Though numbers fell short of past harvests, the transfer of 405 healthy juveniles onto mainlines preserves the production cycle and gives farmers a tangible asset to manage toward future harvests.
Fisheries officials say follow‑up visits, routine maintenance and continued community training will be needed to mitigate fouling and environmental risks and to increase spat recruitment in subsequent seasons. The ministry and its partners portray the Nasau fieldwork as evidence of a sustained commitment to scale up pearl aquaculture in Bua and to integrate rural communities into the blue economy.
