South Australian Pacific Oyster selective breeding program: Building POMS resistance to reduce risk for the South Australian oyster industry
Due to the recent detection of POMS in wild Pacific Oysters in the Port River, the SA industry urgently need POMS resistant oysters. Having POMS resistant oysters stocked onto farms prior to any potential outbreak will be critical for protecting the industry from significant losses and financial impacts.
To achieve a resistance level of over 90% for ≥ one year old oysters, the SA Pacific Oyster selective breeding program will need to establish at least three more generations of families for genetic improvement after the completion of the Future Oysters CRC-P project in 2019.
Establishing the SA Pacific Oyster selective breeding program requires specific techniques and skills. SARDI is the only organisation in SA that has the purpose-built hatchery facility for this species and has produced target numbers of Pacific Oyster families over the last three seasons. SARDI also has a well-established team in oyster genetics and bivalve hatchery technologies.
To support the Stage 2 development of the SA selective breeding program, Flinders Ports, in partnership with the Fisheries Research and Development Corporation (FRDC), ASI, SAOGA and PIRSA-SARDI will jointly fund this project for the SA oyster industry to address POMS risks, and further mitigate the risk factors associated with the spread of POMS outside the Port River related to dredging activities in the Outer Harbour.

Measuring, interpreting and monitoring economic productivity in commercial fisheries
The development of indicators to measure and monitor the performance of fisheries against economic objectives continues to challenge fisheries managers. To date economic metrics have focused on various measures of profitability, and this has been limited to relative few fisheries due to the costs and time involved in collecting the information.
The use of productivity analysis provides an alternative approach to measure and monitor performance in fisheries. It is a broad area of economic analysis that largely estimates how the level and combination of inputs used by fishers affects their level of output, revenue or profitability. From this, the level of efficiency within a fishery can be determined, and how this efficiency level changes over time can be monitored. The role of management in influencing efficiency can also be directly determined. Measures of capacity utilization also provide information on the level (and changes in) excess capacity, which can be used to develop a proxy measure for the optimal fleet size.
Many productivity measures can be derived from available logbook data, while more detailed measures can be obtained from the full economic data (e.g., socio-economics of fishers, vessel characteristics, environmental conditions). These approaches can also provide information about fisher behavior, such as targeting ability in multispecies fisheries, and their response to changes in price and costs, as well as provide information on what is driving changes in profitability (e.g., prices, costs or management). In addition, appropriate measures can be identified to assist managers bridge commercial and other fisheries sectors.
The application of these techniques in Australian fisheries has been limited, and their ability to provide cost-effective information useful for management has not been fully examined. Outside fisheries, productivity has proven to be a useful economic indicator and its potential in Australian fisheries needs to be assessed. This project will meet this need by asking: In what contexts do indicators of productivity and productivity change provide a useful addition to other measures of fisheries economic performance.

The development of indicators to measure and monitor the performance of fisheries against economic objectives continues to challenge fisheries managers.
The purpose of this webinar is to provide an overview of productivity analysis and the role it can play in supporting fisheries management. In particular, the webinar illustrates how productivity analysis can provide information about relevant and cost-effective economic performance indicators for fisheries.
Three case studies - Commonwealth Northern Prawn, SA Spencer Gulf and West Coast Prawn, and Queensland Spanner Crab - are used as examples of what can be measured using typical Australian fisheries data.

Postgraduate funding - Stock structure and connectivity of Black Bream including implications for management
Understanding the demographic characteristics, connectivity and stock structure of a fish species is crucial for identifying the appropriate scale and strategy for management.
Black bream is a slow growing and long-lived finfish species with reproduction confined to estuarine habitats. It is distributed in the estuaries and inshore marine waters of southern Australia, from central NSW to central west coast WA, including Tasmania. Throughout its broad distribution, black bream is thought to be composed of a number of isolated spawning stocks, with limited evidence of movements between estuaries.
In SA, black bream supports important commercial fisheries, and is highly sought-after by recreational anglers. Most of the State-wide commercial catch is taken by the Lakes and Coorong Fishery (LCF) in the Coorong estuary, with smaller contributions taken by the Marine Scalefish Fishery. In 2016, the LCF for black bream, which was historically one of Australia’s most productive black bream fisheries, was classified as ‘overfished’. It is unknown whether this status is reflective of the broader population in SA waters, or if current management arrangements for the Coorong population, which are aimed to promote stock recovery, are adequate in terms of the spatial scale that they apply.
There is a need to understand the demography, connectivity and stock structure of black bream populations across southern Australia (SA, VIC and WA). This information will assist in identifying appropriate scales and strategies for management.
‘People development’ is one of several priorities identified in the FRDC’s RD&E Plan 2015-20. The proposed project will be undertaken by a high-performing student as a PhD project. The student will undertake applied research relevant to FRDC stakeholders (scientists, fishery managers, commercial, recreational and indigenous fishers) in SA, and gain industry experience by being co-supervised by scientists from SARDI. The project will increase fisheries science capacity in SA through training of the next generation of researchers.
Final report
focused on south-eastern Australia. Outcomes contributed to better understanding of stock structure of black bream across southern Australia, and research training of a fisheries scientist now employed at SARDI Aquatic Sciences. Background – The SA RAC identified defining stock structure for black bream in southern Australia, and implications for management as one of three post-graduate student projects to address a range of priority fisheries research. The aim was for the student to undertake direct applied research and gain industry experience by being co-supervised by scientists from the South Australian Research and Development Institute (SARDI), while researching an industry relevant project and be registered at a South Australian university in order to undertake their post-graduate studies. The application was there developed according to this call and after consultation with government researchers, industry and representatives from the recreational sector.
World Fisheries Congress 2020 - Sharing our Oceans and Rivers: a 2020 vision for the world’s fisheries
With fisheries resources under increasing pressure globally from both fishing and non-fishing activities, and the rapid expansion of aquaculture presenting both opportunities and challenges, there is a need to enhance cooperation and collaboration among fisheries professionals to ensure the world’s oceans and rivers are managed sustainably for the benefit of current and future generations.
The WFC2020 aims to attract fisheries professional worldwide by promoting an engaging program featuring internationally recognised keynote speakers that will prompt debate and discussion about new research, fisheries utilisation and access, and management implications and actions.
FRDC funding is sought to assist organisers generate successful outcomes by facilitating greater benefits and appeal to delegates. Funds will contribute to the overall Congress budget, and assist in providing dedicated resources to ensure successful planning and organisation of the event. This may include: attracting high profile international keynote speakers; world-class venue facilities; event promotion; and creating a legacy to the wider community.
This proposal addresses two of FRDC’s national priorities:
(i) Ensuring that Australian fishing and aquaculture products are sustainable and acknowledged to be so.
(ii) Improving productivity and profitability of fishing and aquaculture.
The WFC2020 provides an opportunity for the Australian and New Zealand seafood industries to demonstrate to the international fisheries community and the broader public that they are leaders in sustainable management of fisheries and aquatic systems, producing some of the highest quality sustainable seafood in the world. Furthermore, the Congress will provide the local fishing, aquaculture, recreational and indigenous sectors with unparalleled access to the latest research, technological developments and updates on global markets.
People Development is also addressed in this proposal, in encouraging knowledge transfer and R&D adoption within the international fisheries community and providing an opportunity for the Australian and New Zealand fishing industries to take a lead role in debating and discussing current and future research.
Final report
The World Fisheries Congress is the premier international fisheries congress, bringing together research, industry and management to discuss the latest advances in fisheries world-wide. The 8th World Fisheries Congress, hosted from Adelaide, Australia from 20 to 24 September 2021, was led
by the South Australian Government (Department of Primary Industries and Regions – PIRSA, including the South Australian Research and Development Institute – SARDI) in partnership with the Adelaide Convention Bureau and the Adelaide Convention Centre and the Fisheries Research and
Development Corporation (FRDC); and support from the Australian Society for Fish Biology (ASFB) and industry and government agencies from other jurisdictions in Australia and New Zealand. The World Fisheries Congress 2021 (WFC2021) was delivered as a fully virtual event allowing the
international fisheries community to come together and exchange ideas at a time when travel was restricted due to the COVID-19 pandemic.
In total, the Congress delivered over 800 presentations, covering a broad range of topics critical to the future of fisheries, and attracted 1,166 delegates from 60 countries.
The Congress provided an opportunity to reflect on how much has changed since the first World Fisheries Congress was held almost 30 years ago, as was evident by the developments and thought-provoking work presented and discussed over the week of the Congress. The Congress also
highlighted the many issues that remained, as well as identified new issues that have emerged. Importantly, discussions and presentations indicated that despite the persistence of some issues, we have advanced our thinking and actions and are moving forward in the right direction.
Every session and presentation were recorded and will remain available on the WFC2021 virtual portal for six months post congress. Plenary presentations and presentations of student award winners have been made publicly available on the WFC2021 website.
