This project delivered the foundational research needed to support the development of a tropical rock oyster aquaculture industry in northern Australia. Led through the Cooperative Research Centre for Developing Northern Australia (CRCNA), the research focused on the Blacklip Rock Oyster (Saccostrea spathulata) and addressed key barriers to commercial production.
The project was structured around three main areas: biosecurity and species identification, hatchery production, and on-farm grow-out methods. Researchers conducted disease risk assessments and developed biosecurity protocols to guide safe movement of oysters and broodstock. The project also established the recognised industry name “Blacklip Rock Oyster”, helping provide clarity for regulation and marketing.
Significant progress was made in hatchery production. New protocols for broodstock conditioning, larval settlement and nursery culture were developed at the Darwin Aquaculture Centre, resulting in the world’s first hatchery manual for Blacklip Rock Oysters. These improvements increased larval settlement rates and enabled the production of hundreds of thousands of juvenile oysters for trial farms.
Field trials at South Goulburn Island and Groote Eylandt tested grow-out systems and farming gear under tropical conditions, working in partnership with Indigenous organisations including Yagbani Aboriginal Corporation and Groote Aqua Aboriginal Corporation. The trials demonstrated promising survival and growth across different production systems and provided practical guidance for future farms.
Overall, the project established the scientific, technical and operational foundations for a new aquaculture industry in northern Australia, supporting future commercial development and opportunities for Indigenous-led oyster farming enterprises.
