Need

There are numerous Australian jurisdictions that have faced and are currently facing management challenges with Snapper stocks in decline. It proposed that a national Snapper workshop is needed to bring together from each jurisdiction fisheries managers, scientists and key stakeholders from the commercial and recreational fishing sectors to:

(1) Communicate findings on Snapper research, gain an insight into the challenges, successes and learnings from management arrangements implemented in each jurisdiction.
(2) Identify a national approach to collaborate and manage a Snapper stock that crosses jurisdictional boundaries
(3) Develop a set of national R&D priorities for Snapper, in particular dealing with the issue of ‘hyperstability’.
(4) Develop a tool kit to support fisheries managers recover Snapper stocks.

The main aim of the workshop is for each jurisdiction to exchange information on Snapper and to ensure that Snapper R&D has a national co-ordinated approach that addresses the challenges being faced, makes the most efficient use of available resources and integrates key stakeholders such as the recreational and commercial fisheries, government and research providers.

Objectives

1. To identify key issues and challenges for Snapper, review Snapper research, and critique jurisdictional management arrangements.
2. To explore a national approach to collaborate and manage cross-jurisdictional Snapper stocks.
3. To explore and develop a set of innovative national R&D priorities for Snapper that address the challenges being faced.
4. To develop a tool kit to support fisheries managers to recover depleted Snapper stocks.

Fishing for change: A social marketing approach to reduce the recreational harvest of Snapper and Pearl Perch in Queensland

Project number: 2019-078

Need

Snapper and pearl perch are depleted in Queensland and further reduction in fishing pressure is needed to rebuild stocks back to target levels. The Queensland Government announced actions to improve stocks on 1 Sep 2019 , which followed the announcement that they would also introduce Fishing Aggregation Devices (FADs). Given previous regulatory approaches have been unsuccessful in improving stocks of both species, it is proposed that regulatory changes, complemented by the implementation of action mapping and social marketing, may be more effective.

Social marketing delivers innovative solutions that people value and that support desired outcomes. It draws on behavioural science and a psychology-based understanding of how and why people behave, what motivates them to change and what prevents behaviour change. Work in Australia has documented the use of behavioural incentives to encourage voluntary compliance of recreational fishers as well as testing social norms as a tool to encourage compliance within an experimental recreational fishery setting. This work sets a foundation to apply the approach to Queensland recreational fishing.

The Queensland Government’s announcement that it will invest $1 million in FADs offers an opportunity to change recreational harvesting behaviour. FADs can attract pelagic species increasing the diversity of fish species recreational anglers can target and therefore could shift fishing effort away from more vulnerable demersal species (e.g. snapper and pearl perch).

This project will use a social marketing approach that initially focuses on understanding if and how recreational fishers can be motivated and moved to use FADs as a strategy to reduce snapper and pearl perch fishing. This project will also consider a full range of strategies and behaviours and their relative potential to help reduce snapper and pearl perch recreational harvests.

A key challenge in addressing the issue is the numerous and diverse stakeholders with an interest in recreational fishing – many with conflicting agendas. Approaches that engage a broad cross-section of stakeholders together can identify priorities for action and generate solutions to achieve the outcomes sought.

Objectives

1. Engage with stakeholders to develop a shared sense of responsibility, capture knowledge and identify potential solutions.
2. Develop and test a behaviour change program targeted at recreational fishers that aims to reduce the recreational harvest of snapper and pearl perch in Queensland.
3. Identify the most effective behaviour change interventions that could be further rolled out in Queensland or in other states or to target other fish.
4. Share knowledge and ownership of a behaviour change approach with key stakeholders.

Need

Ciguatera Fish Poisoning (CFP) causes the largest number of seafood-related food safety incidents in Australia. In NSW and southern QLD waters, CFP is mostly related to Spanish Mackerel (Scomberomorus commerson). Ciguatoxins (CTXs) produced by marine microalgae (Gambierdiscus spp), are polyether toxins that accumulate in fish and cause CFP when fish are eaten. CTXs are heat stable, odourless, tasteless, and toxic at low concentrations, therefore it is very difficult to distinguish toxic fish. In NSW, since 2014, 31 people have contracted CFP after consuming Spanish Mackerel caught locally, mostly through recreational fishing.

Validated commercial monitoring methods for CTXs are unavailable internationally, although research tools for CTX measurement have been developed. Regulatory methods for CFP prevention are to avoid certain fish species, fish of certain sizes (ie >10kg), or fish from certain regions. In Australia, effective prevention methods have not been clearly evaluated. This results in Spanish Mackerel that are safe to eat potentially being excluded from sale, resulting in significant losses (ie > ~$200k p.a in NSW). This project addresses this issue, which was identified as high priority in the Australian ciguatera research strategy formulated at a recent workshop (27-28th March, 2019).

In 2014, FRDC (Tactical Response) and the NSW Recreational Fisheries Trust funded an initial study on the incidence of CTXs in NSW Spanish Mackerel. CTX was present in flesh and liver samples (1-7% incidence), and was not clearly correlated with the weight of individual fish. This information showed that CFP risk management may require reassessment. This project will advance knowledge by: evaluating methods of detection of CTXs; determining detailed predictive data on CTX incidence; and evaluating environmental and biological factors associated with CTX in Spanish Mackerel to allow for an evaluation of risk assessment strategies. This information will benefit industry by enhancing consumer safety and industry confidence, and enabling the sale of safe Spanish Mackerel.

Objectives

1. Determine industry CTX needs and conduct of review of available CTX measurement tools (including cell based assays, ELISA kits, and LCMS) against these needs. Conduct an assessment of the currently available screening tools to determine which, if any, hold promise for industry use. Conduct a viability assessment for how a tool might be used in industry or, if none of the currently available tools are appropriate, make recommendations for future activities to develop a rapid screening tool that meets industry needs.
2. Obtain samples of flesh and liver from ~300 individual Spanish Mackerel of all sizes caught in Industry relevant regions of NSW waters over a period of 2 years, as well as length, weight, sex and site information, with the participation of the Sydney Fish Market and commercial fishing Cooperatives. Obtain samples from any individual Spanish Mackerel associated with illnesses in NSW or QLD. Measure CTX1B and other available CTX analogs using best practice methods identified in Objective 1.
3. Conduct statistical data analyses of all available data on CTX concentrations in Spanish Mackerel in comparison to biological and environmental variables.Develop recommended options for food safety risk management for Spanish Mackerel in NSW that will allow for a viable industry while protecting public health.

Summary

Ciguatera Poisoning (CP) is an illness through the consumption of fish containing naturally occurring toxins, and is considered a high risk for Australian seafood safety. Ciguatoxins (CTXs) are produced by benthic microalgae (Gambierdiscus spp). In Australia, CP cases are related to fish caught in Queensland (QLD), Northern Territory (NT) and New South Wales (NSW) waters. Spanish Mackerel (Scomberomorus commerson) is the main species that has resulted in CP cases from fish caught in NSW and sub-tropical QLD, and is an important commercial species. An inability to address the risks of CTXs has led to illnesses, with the potential to damage public perceptions of seafood with economic losses to industry. Currently no validated monitoring or measurement methods are available. Prevention methods used internationally are to avoid larger fish of certain species, avoid certain fish species altogether, or avoid fish from certain regions.

Need

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.

Objectives

1. Develop selective families with 90% POMS disease resistance for ≥ one year old Pacific Oysters
2. Support the SA industry by provision of high POMS resistant broodstock for commercial spat production

Summary

A total of 221 new selectively bred families were produced at the South Australian Research and Development Institute (SARDI), West Beach, between 2019 and 2023, meeting project objectives. The 2019-year class was challenge tested in the Port River, SA for POMS resistance, after which the imported Tasmanian broodstock were incorporated into the program and the objective changed to improve both POMS resistance and POSS in SA. Details of the POSS field challenge tests and results will be available in the final report of FRDC project 2020-064. In the 2022 families, the last year class produced at SARDI, the average EBV of the top five POMS resistant families was 100% and the average EBV of the top five POSS families was 90%.

Need

It is very clear that fishing-technology research to improve resource harvesting is a priority need for the future sustainability of fish trawling in Australia. The issue is quite poignant, considering that over the past 15 years, there has been a massive reduction in the total number of trawlers in Australia, and lower profits among remaining operators struggling to remain viable. Innovative modifications and refinements to existing systems that improve selectivity and reduce environmental impacts and costs are an urgent priority to ensure economic viability. Such developments are difficult to achieve by individual fishers without quality research, development and extension that is adequately resourced.

More specifically, there is a clear need to maintain progress towards developing innovative, high-priority technological modifications to fish trawls in the CTS and GABTS that mitigate sustainability issues while maintaining target catches at existing levels. Equally important, ratified designs then need to be tested across fleets to encourage adoption and refinement as a precursor to eventual legislation. Ultimately, satisfying these needs will contribute towards improving the social licence and economic return of trawl fisheries in the SESSF, while helping to ensure their ongoing sustainability and address what remains one of the most controversial issues facing bottom trawling.

Objectives

1. Review the available domestic and international literature and data, and consult with a project stakeholder committee (comprising representatives of the CTS, GABTS, NSW PFA and AFMA) to prioritise modifications to be formally assessed for their utility in minimising bycatch, while maintaining target catches among trawls used in the CTS and GABTS.
2. Based on the outcomes of 1 above, assess the utility of existing and new modifications to trawls for minimising bycatch, while maintaining target catches in the CTS and GABTS.
3. By providing strong economic incentives through improved efficiencies, and via applied extension activities, encourage the wide-scale voluntary adoption and ongoing exploration of appropriate best-practice technologies that cumulatively reduce bycatches, while maintaining target catches in the CTS and GABTS.

Summary

This project sought to produce the first-ever review of technical options for improving fish-trawl selectivity around the planet and then use this information to address a deficit in experimental work quantifying the utility of industry-developed and new selective-gear modifications in the Commonwealth Trawl Sector (CTS) and Great Australian Bight Trawl Sector (GABTS) of the Southern and Eastern Scalefish and Shark Fishery (SESSF). The work was completed during a four-year collaboration (from September 2020) between the New South Wales Department of Primary industries (NSW DPI), Fishwell Consulting, the Australian Fisheries Management Authority (AFMA), Commonwealth Scientific and Industry Research Organisation (CSIRO), South East Trawl Fishing Industry Association (SETFIA) and the Great Australian Bight Industry Association (GABIA). Ultimately, by highlighting regional industry efforts and identifying and validating the benefits of new options to reduce one of the most controversial issues facing bottom trawling, the project contributes towards improving the social licence and economic return of trawl fisheries in the SESSF, and supports ongoing Australian research into technological solutions to ensure fishery sustainability.

Measuring, interpreting and monitoring economic productivity in commercial fisheries

Need

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.

Objectives

1. To review the use of productivity analysis as a performance indicator and in management assessment in fisheries and assess the contexts in which it provides additional insights for effective management.
2. To demonstrate the use of productivity measurement and analysis as a performance indicator in three Australian fisheries.
3. To develop a guide for managers to illustrate how productivity analysis can provide relevant and cost-effective economic performance indicators and how these can be used to inform management decisions.

Summary

This report brings together a body of knowledge from over 30 years of Australian and international research and illustrates how productivity analysis can provide additional insights for fisheries management. Our comprehensive review identifies a maturing of the literature from asking questions simply about ‘what’ towards ‘how’ and ‘why’, with key gaps remaining. Using the findings from the review to inform our methodological approach, we analyse three Australian case studies to illustrate: how different metrics can be used to identify productivity in fisheries; the consistency of these metrics; how they relate to other measures of economic performance; and, where relevant, the impact of productivity measurement on management change. The case studies are the Commonwealth Northern Prawn Fishery, the South Australian Spencer Gulf and West Coast Prawn Fisheries, and the Queensland Spanner Crab Fishery.
