Summary
The sensitivity of an overall passive surveillance system is difficult to determine due to variability in factors such as disease characteristics, passive surveillance stakeholders and the likelihood that disease events will be reported and investigated. The WOAH Aquatic Animal Health Code also stipulates the primary evidence for historical freedom is passive surveillant information generated by a country’s early detection system that needs to be sufficiently sensitive.
Scenario tree m ....The sensitivity of an overall passive surveillance system is difficult to determine due to variability in factors such as disease characteristics, passive surveillance stakeholders and the likelihood that disease events will be reported and investigated. The WOAH Aquatic Animal Health Code also stipulates the primary evidence for historical freedom is passive surveillant information generated by a country’s early detection system that needs to be sufficiently sensitive.
Scenario tree modelling (STM) can be used to overcome those challenges. STM uses quantitative statistical methods to estimate the sensitivity of various components of the surveillance system (e.g. presentation of disease signs, disease recognition and reporting). These estimates can then be used to identify critical points in the system to which interventions can be targeted to improve the system. STM can be applied to any aquatic disease/industry of interest and there are some successful examples for terrestrial diseases/industries, both in Australia and overseas.
Two aquatic animal disease agents of trade and biosecurity significance, WSSV and megalocytiviruses, will be evaluated as case studies. These diseases are subject to import biosecurity measures and have significant production impacts, as they severely affect farmed and wild aquatic animal species that are valued by many stakeholders (e.g. aquaculture, capture fisheries, recreational fisheries and conservation groups). A sound STM assessment of each case study will support our early detection system through a quantitative evaluation of the speed of the detection, and improve our emergency disease response strategy by determining areas in our passive surveillance that, once strengthened, will provide a greater return on future investment.
As mentioned above, increasing the sensitivity of Australia’s passive surveillance is a national priority. This project is identified in AQUAPLAN 2022-2017 as Activity 3.3. The outcomes of this project are also used for other AQUAPLAN activities, National surveillance strategy (Activity 3.1) and Sector-specific surveillance plans (Activity 3.2). The data produced from this project will provide recommendations for various interventions to improve the overall performance of the passive surveillance system for the participating industries.
More broadly, the Fisheries Research and Development Corporation R&D Plan 2020-2025 identified building capability and capacity for biosecurity as a priority. In alignment with the R&D plan, successful outcomes of this project will improve understanding of disease transmission pathways which will enhance biosecurity practices. It will improve allocation of biosecurity resources (by identifying the most effective and cost-efficient way of investing resources in surveillance to get the best return), minimise biosecurity threats (by enhancing passive surveillance to accelerate an early detection) and improve market access for associated industry producers (by providing quantitative information on their passive surveillance sensitivity as a market access negotiation tool).
Objectives: 1. Quantitatively evaluate the sensitivity of Australia’s passive surveillance system for white spot disease 2. Quantitatively evaluate the sensitivity of Australia’s passive surveillance system for megalocytiviruses Read moreRead less

Southern Calamari are important to multiple commercial and community fishery sectors in SA. Southern Calamari are now managed using a TACC for the commercial MSF and have specified resource allocations for recreational, Aboriginal/Traditional, Charter Boat, GSV prawn and SG prawn fisheries.

Southern Calamari are now managed using a TACC for the commercial MSF and have specified resource allocations for recreational, Aboriginal/Traditional, Charter Boat, GSV prawn and SG prawn fisheries. However, the current assessment program does not capture the importance of this species and cannot support the level of management required. The primary outcome of this project will be to develop an assessment program for Southern Calamari in SA that can be used to assign stock status and provide TACC setting advice to fisheries management.
Like many cephalopod assessments, the current SA Southern Calamari assessment is basic as scientific advances have not occurred at the same rate as advances for finfish or crustacean assessment methods. Therefore, the successful development of an assessment program for Southern Calamari in SA would provide a valuable scientific contribution to several other Australian squid fisheries as they often encounter similar assessment difficulties
Overcoming key knowledge gaps and incorporating information on environmental drivers will be a key focus of this project, in order to develop an assessment that accounts for the full complexity of cephalopod population dynamics. However, there are limited resources to undertake an assessment in SA as the commercial MSF has a low gross value product (GVP) but has high assessment needs across several species. Therefore, a cost-effective assessment program must be developed to allow for its regular application, which is necessary for short lived species such as Southern Calamari.
The proposed project will address two FRDC strategic plan outcomes (Growth for enduring prosperity, and best practices and production systems) by developing a best practice assessment program that can be applied for Southern Calamari in SA and be extended for use in other fishery jurisdictions. An assessment program that provides confident management advice, such as TACC setting, will maximise resource use across all sectors by establishing a robust stock assessment that increases certainty in stock abundance and allows sustainable fishing strategies to be developed.
Objectives: 1. Review global cephalopod assessments to identify potential assessment methods for Southern Calamari and how environmental variables could be incorporated. 2. Evaluate the suitability of available fishery-dependent and fishery-independent data from the SG and GSV prawn fisheries to develop recruitment indices. 3. Develop Southern Calamari growth models for SG and GSV and evaluate the influence of environment on seasonal growth rates. 4. Outline the most suitable and cost-effective assessment program option for Southern Calamari in SG and GSV Read moreRead less

1. undertake research and demonstrate the effects of COVID-19 and international trade disruptions on the industry’s financial wellbeing and economic contribution, as a narrative incorporating the pre-, current and post-disruption era;
2. investigate and implement enhancements to the WRL MEY model based on verified stakeholder feedback; • MEY modelling is based on (among other factors) expected longer-term beach prices for lobster achieved by fishers. Beach prices are themselves underpinned by prices achieved in domestic and export markets for live, frozen and other processed forms of western rock lobster, and supply chain costs — all of which have changed markedly over the past couple of years and have influenced the longer-term outlook considerably. o Domestic markets have absorbed higher volumes of Australian product over the past two years than in the previous ten, encouraging a pivot by processors to include more cooked, frozen and other processed product in the product portfolio. o Frozen and chilled product has also been demonstrated to have general acceptance in overseas markets, albeit at lower prices than achieved by similar live product. o Air and sea freight costs and reliability have been adversely compromised in the face of the continuing COVID-19 pandemic, with the medium-term outlook for freight costs expected to be a multiple of pre-COVID rates – affecting the relative attractiveness of domestic versus export markets. o Processors and marketers have explored alternative export markets and paths to market in the wake of political uncertainty and trade disruptions. There is a need to understand the implications of this market shift on the net beach prices achievable by fishers, which will be achieved through a better understanding of the changes in market access and supply chain costs (transport, live holding, handling, additional processing, freight forwarding by air and by sea). o Taken together, this suite of change constitutes a significant, and potentially longer-term, challenge to the western rock lobster industry that has high potential to bring about changes in industry structure.
3. research and implement mechanisms by which individual fishers / business owners can benchmark their businesses against relevant industry economic standards.
• Benchmarking aims to improve the internal performance of fishers' private business operations by providing each business with an opportunity to compare itself to the industry's performance • Benchmarking is not limited to economic metrics, including physical metrics such as fuel use that enable a more granular understanding of the carbon footprint of the fishing fleet. • The aim is to generate an understanding of the range of cost structures in the fishing fleet, to better inform the cost elements of MEY modelling for economic sustainability of the fishery.
4. investigate and implement enhancements to the WRL Global Trade Report.
• The pandemic and its ongoing turmoil, combined with trade disruptions to Australia’s live exports, has brought about a change in global lobster trade flows into the highest volume, highest value market – at Australia’s expense. o The resultant situation includes a loss of market share and value to alternative suppliers of live spiny lobster, other lobster species, and other high value crustaceans. o Consumer preferences have shown signs of changing in response to COVID and associated health policies, regulations and restrictions. During the course of the pandemic, consumption of rock lobster pivoted to at-home consumption, with some preference-shifting to frozen product, particularly in countries with aggressive health policies that enacted operating restrictions on restaurants and larger gatherings.
5. research and implement mechanisms by which WRL's Global Trade Report, MEY Model and Markets Dashboard would work together with DPIRD's Harvest Strategy to underpin TACC setting into the future, adding considerable benefit to government as the resource manager by supplying timely, independent, industry-oriented information to the consideration set
Objectives: 1. Enable the Global Trade Report the MEY Model and the Markets Dashboard to work together with the Harvest Strategy to underpin TACC setting and ensure the continued sustainability of the stock. 2. Demonstrate the effects of the SARSCoV2 pandemic and trade disruptions on the industry’s resilience, economic contribution and adaptation to changing market forces. 3. Develop benchmarks for use by fishers’ businesses against industry economic standards to enhance industry reslience and adaptation to trade disruptions. 4. Ensure usability of economics data by driving further integration of data sets, models and tools, and building into the digitization program. Read moreRead less
Marine spatial planning (MSP) has emerged in recent years as a tool for sea use management.

However, MSP requires adequate and accurate information on the biophysical state and usage of the marine environment. Such data often exists, but generally not in a format which allows several data layers to be overlaid in order to identify potential conflicts/trade-offs.
Marine information management and data science are developing areas of research addressing how to easily access, collate and use multiple disparate sources of data to support marine ecosystem and resource management. Significant efforts are made to standardize the collection, reporting and open access to marine data in existing databases and platforms, but these platforms commonly use specific (and differing) sources and types of data. Challenges arise from disparities in spatiotemporal resolution, uncertainty in geographic positioning, diversity of data sources and types, lack of access, and often limited metadata standards within and across scientific disciplines. To address this problem, this project will identify, compile and standardize spatially-resolved datasets required for marine social-ecological system management for Tasmanian State waters. No new field-based data will be collected, although secondary analysis may create new datasets. Rather than duplicating effort, this project builds on accessible databases and platforms to provide recommendations on the availability and best practices of using marine data to support data-driven decision-making processes in Tasmanian waters.
Perhaps more importantly, this project will also compare various off-the-shelf tools to identify trade-offs at various scales and resolutions of interest. Currently, many off-the-shelf spatial multi-criteria decision-analysis tools and methods exist (e.g. Marxan, CommunityViz, SSANTO…). More have been developed for more specific uses (e.g. the Aquaspace tool - developed to plan trade-offs with aquaculture in Europe). Research is required to identify the most appropriate tools for use in identifying conflicts/trade-offs in Tasmanian waters, given the needs of decision-makers and the available data.
Finally, this project will provide planning for database longevity. Objectives: 1. Identify, collate and create database of available spatially-resolved environmental, resource use, and cultural heritage data for Tasmania’s state waters 2. Develop an interactive web-based mapping service to display and download Tasmania’s Marine Atlas data 3. Analyse and compare existing trade-off tool(s), to be used in conjunction with Tasmania’s Marine Atlas, for use in decision-making 4. Establish protocols for ongoing updates (automatic and manual) to, and management of, Tasmania’s Marine Atlas database Read moreRead less

Summary
The Tasmanian salmon farming industry has undergone exceptional production and profitability gains in its short history and has ambitious targets for the future. A report commissioned in 2015 indicated an annual Industry gross output of $1.12 billion and the direct employment of almost 2800 full time positions. Projecting forward, the Industry is confident of turning over $2 billion by 2030, with clear implications for continued jobs growth and economic impacts within Tasmania.

A report commissioned in 2015 indicated an annual Industry gross output of $1.12 billion and the direct employment of almost 2800 full time positions. Projecting forward, the Industry is confident of turning over $2 billion by 2030, with clear implications for continued jobs growth and economic impacts within Tasmania. To achieve this, and to strengthen linkages with Government, the Tasmanian community and myriad stakeholders, ongoing proactive and reactive research is vital. This point is particularly salient given the present need to diversify the research portfolio to address potential constraints to industry growth. For example, spatial limitations on the expansion of grow-out operations in sheltered waters have resulted in new research and development approaches to investigate and trial offshore farming operations. Expanding the scope of the research and development program in such a manner is replete with complexities requiring significant input and coordination by the TSGA.
The portfolio of research funded between the FRDC and TSGA is significant, with around $4m of combined funding available each year – an amount steadily growing as Industry GVP grows. There is a need for both the FRDC and TSGA to have the capacity to actively manage this research portfolio, understand the current and future opportunities requiring research, development and extension (RD&E), and to communicate outputs to all stakeholders. Previously, these tasks were largely undertaken by the former TSGA CEO and, at times consultants were hired on an ad hoc basis. Given industry expansion however, there is a pressing need for a permanent role dedicated to addressing and coordinating the management needs of a RD&E portfolio that is growing in size, scope and complexity.
Objectives: 1. Coordinate Atlantic salmon farming RD&E planning and management so that RD&E is strategically prioritized to address Industry needs and delivered cost-effectively. 2. Communicate information and the extension of R&D outputs to support and promote the adoption of new technologies and scientific developments. 3. Develop an updated RD&E Strategy for the Industry to guide research for the period 2020-2025. Read moreRead less

This is central to maintaining public confidence in the salmon industry. Demonstrating best practice in environmental sustainability requires that the environmental footprint of the industry is well understood and contained within acceptable levels. An environmental monitoring program that assesses the environmental performance of farming at both local and system wide scales will provide this understanding, enabling appropriate regulatory responses. The development and validation of a biogeochemical model that can estimate the natural systems capacity to assimilate salmonid derived nutrient inputs at both local and broader system scales provides the capacity to both understand current environmental conditions and forecast the environmental responses under alternate management responses. This combination of a reliable and “fit for purpose” environmental monitoring and modelling program will help meet the needs and expectations of a science based adaptive management framework necessary for the proposed development of salmonid farming in Storm Bay. Objectives: 1. Develop a robust monitoring program 2. Provide a comprehensive map of benthic habitats and bathymetry of the Storm Bay region and assessment of change at key focus areas 3. Develop and apply a lease scale model for assessing the environmental footprint of dissolved and particulate farm inputs 4. Assess the interactions between farming and the receiving environment 5.

By combining this greater coverage with information derived from commercial fishers (e.g. days when gear is drowned or lost to determine key current velocities) a purpose built webapp can be developed, hosted on an existing service, which allows fishers to asses the risks posed by ocean currents to their fishing operation before they set their gear. This would also allow for fishers to predict days when drowned gear may resurface and therefore the fishing operation may continue.

This would also allow for fishers to predict days when drowned gear may resurface and therefore the fishing operation may continue.
In addition to this helping the fishing operation, greater current modelling coverage over this part of the fishery will allow for the fine-scale assessment of the links between water movement and puerulus settlement. As part of FRDC project “2016-260 WRL IPA: assess causes and implications of anomalous low lobster catch rates in the shallow water areas near the centre of the Western Rock Lobster fishery” 40 additional puerulus collectors will be added to the current DOF monitoring program which will provide extensive coverage of settlement rates between Seven Mile, Dongara and Jurien Bay.
Objectives: 1. Establish additional coastal radar station 2. Establish a predictive warning system for ocean conditions that can be used by the WRL fishery to improve efficiency 3. Assess the relationship between water circulation and puerulus settlement rates Read moreRead less
