Need

In October 2018, FRDC funded the first national workshop on tropical oyster aquaculture (Osborne, 2018). This successful event addressed a need to foster greater collaboration across the various projects and provide strategic direction to future research and development activities. Since then, significant progress has been made in tropical rock oyster RD&E, both in Australia and internationally, and work is underway across the tropics to further develop the industry (Nowland et al., 2019). To maintain momentum and continue to foster collaboration in this field, an International Tropical Rock Oyster Workshop will be hosted by NT Fisheries and The Pacific Community (SPC), supported by the Cooperative Research Centre for Developing Northern Australia (CRCNA), in the days before the World Aquaculture Conference 2023 in Darwin. The workshop will bring together a broad range of stakeholders to discuss the status and current knowledge of tropical oyster aquaculture research and development. This will provide an opportunity to share experiences and develop an international network for tropical oyster aquaculture. As well as to discuss and document current bottlenecks/issues confronting tropical oyster farming, such as; hatchery production, disease, grow-out technology and shellfish quality assurance.

This workshop is running alongside the World Aquaculture Conference 2023 in Darwin. The project team have identified key people in the region (commercial produces and Traditional Owners) that would add additional value to the workshop and the World Aquaculture Conference 2023. However, they do not have the means to fund their own attendance.

Workshop information
Date: Sunday 28th & Monday 29th May 2023
Location: Convention Centre, Darwin NT, Australia
Sessions will cover:
Day 1 (Sunday 28th May; 8.30am – 5.00pm):
- Regional updates on existing tropical oyster aquaculture; Australia (NT, Qld and WA), Fiji, Malaysia, New Caledonia, Tahiti, Vietnam, Cuba, Brazil, New Zealand, Indonesia and the Philippines
- Evening social event (from 5.30pm): Networking drinks and nibbles at the Oyster Bar.
Day 2 (Monday 29th May; 8.30am – 3.00pm):
- Focus topics and breakout sessions on major issues confronting development of tropical oyster aquaculture, such as; hatchery production, food safety, disease and business development.
A detailed program will be distributed in the weeks leading up to the workshop.

Need

RD&E that addresses critical hurdles to Aboriginal capacity and enterprise development (e.g. quality assurance strategies) have been identified as priority areas of the NT RAC and the Indigenous Reference Group (IRG). NT Fisheries has been conducting research to support Aboriginal aspirations to establish tropical oyster farms in the Northern Territory (NT).

Heavy metals have been a longstanding concern as an impediment to the development of a tropical oyster industry. Cadmium (Cd) bioaccumulates in the tissue of oysters, and unlike E. coli or toxic algae, has a long depuration period. As a result Cd levels are a major determining factor on the saleability of farmed tropical oysters. McConchie, D.M & Lawrance, L.M (1991) and FRDC Project 2012-223 identified high Cd concentrations, which varied considerably across locations and water depth, in blacklip oysters (Saccostrea echinata) at location in Shark Bay, WA and South Goulburn Island, NT respectively. Following these projects naturally occurring heavy metals have been a presumed barrier to the establishment of an oyster industry in the NT, due predominantly to the exceedance of Cd trigger levels in the Food Standards Australia and New Zealand (FSANZ).

However, recent testing on market sized oysters farmed on long line trials at Pirlangimpi on Tiwi Islands have not shown high heavy metal concentrations and complied with the FSANZ. This suggests that Cd exceedance may not be an issue in all locations. We propose a multi-location survey of blacklip oyster (Saccostrea echinata) heavy metal concentrations across the NT to identify the best locations for commercialisation of this emerging aquaculture species. With the aim of identifying locations, like Pirlangimpi, that could produce oysters that comply with the Food Standards Australia and New Zealand (FSANZ). The results are needed to inform the development of a NT tropical oyster industry and the establishment of a NT shellfish quality assurance program.

Objectives

1. Map the distribution and concentration of Cadmium in wild blacklip oysters across the Northern Territory.
2. Aboriginal communities better understand the role of shellfish quality assurance programs and the implications of Cadmium on oyster farming.
3. Risks associated with Cadmium are better understood and inform the development of a NT Shellfish Quality Assurance Program.
4. Knowledge is shared and retained through Aboriginal participation in the research project.
