Need

The current National Guidelines were developed through the FRDC (Project 2010/061) with recognition of the need for a coordinated, nationally consistent approach to establishing harvest strategies for Australian fisheries. At this time, the Commonwealth Harvest Strategy Policy and Guidelines (2007, now updated) provided a foundation for harvest strategy development in Commonwealth managed fisheries, however implementation of the key elements of harvest strategies (defined objectives, indicators, assessments, reference points, trigger points and decision rules) varied across jurisdictions, and gaps remained for data limited fisheries.
Similar to the proposed project, the AFMF and FRDC recognised that support for development of harvest strategies could be improved through development of the National Guidelines that focused on less developed areas of harvest strategy policy, including cross-jurisdictional and recreational management arrangements, and incorporating quadruple bottom line (ecological, social, cultural and economic) analysis into fisheries decision making.
As harvest strategy policy and incorporation of quadruple bottom line ecologically sustainable development (ESD) principles have increased as management priorities, harvest strategies have sought to incorporate increasingly challenging issues, in many cases continuing to use disparate approaches between jurisdictions that arguably hold the same objectives and responsibilities, as well as potentially competing interests.
In many cases, harvest strategy policy and development has been held back from achieving quadruple bottom line objectives due to a lack of consistency in the outlook and approach between jurisdictions, and available guidance for dealing with the complexities associated with multi-species, multi-sector or multi-jurisdictional issues. With significant developments occurring around traditional fishing and management, progressing the inclusion of cultural fishing specific objectives is also required.
In addition, the review provides opportunity to address broader issues including the relationship and function of harvest strategies in association with shared access with competing users, cultural interests, ecological issues (e.g. habitat degradation, pollution and climate change), and marine conservation areas, as well as options, incentives and trade-offs for improving data, monitoring and assessment in data poor fisheries or sectors.
The proposed review will ensure the National Guidelines remain a prominent, independent and contemporary guide for fisheries jurisdictions, managers, researchers, fishers and stakeholders in supporting the review of harvest strategy policy frameworks and the development of harvest strategies that in many cases seek to resolve complex issues and balance competing interests.
To achieve this, the proposed project aims to:
1. Review and update the National Guidelines to Develop Fishery Harvest Strategies to ensure the National Guidelines are consistent with current harvest strategy utilisation, address contemporary fisheries challenges and the most up to date information available;
2. Take stock of harvest strategies in Australia (by jurisdiction) and internationally, including how many fisheries now have operational harvest strategies adopted and those under development; and
3. Produce a report with the updated National Guidelines coupled with a detailed communication plan and associated materials to promote and communicate the outcome of the review with all stakeholders.

Objectives

1. To review and update the National Guidelines to Develop Fishery Harvest Strategies (2014) to ensure the National Guidelines are consistent with current harvest strategy utilisation and reflect the most up to date information available
2. To take stock of harvest strategies in Australia and internationally (by jurisdiction) including how many fisheries now have operational harvest strategies adopted and those under development
3. To produce a report with the updated National Guidelines coupled with a detailed communication plan to promote the outcome of the review

An updated understanding of Eastern School Whiting stock structure and improved stock assessment for cross-jurisdictional management

Need

Most of the commercial catch of Eastern School Whiting is taken by the Commonwealth South East Trawl (SET) sector of the Southern and Eastern Scalefish and Shark Fishery (SESSF) in eastern Victorian waters and Bass Strait and in the NSW Ocean Trawl Fishery in central and northern NSW waters. Smaller amounts are reported from inshore state waters of southern NSW, Victoria and Tasmania (Conran et al. 2018).

Eastern School Whiting have been managed by catch quotas in Commonwealth fisheries since 1993. A Commonwealth Tier 1 stock assessment is completed every 3–5 years to estimate the recommended biological catch (RBC) for the entire biological stock. Historically, the estimated discards and average state catches were then subtracted from the RBC to set the Commonwealth total allowable catch (TAC). The most recent stock assessment in 2017, calculated an RBC of 1,606 t and the 2019–20 Commonwealth TAC was set at 788 t.

A new basket TAC for Eastern School Whiting and Stout Whiting was introduced in NSW state waters from May 2019 (set at 1,189 t for the 2019–20 fishing year). While some of this catch is likely to comprise Stout Whiting, the combined total of the two independently determined TACs could permit total catches of Eastern School Whiting that exceed the current RBC for the shared stock. Furthermore, as part of these management reforms, the NSW Southern Fish Trawl Fishery is to transition into the Commonwealth SET, which will include allocation of Commonwealth quota to existing state operators. A review of the existing cross-jurisdictional stock assessment and management arrangements for this species is urgently needed to ensure sustainable fishing continues to occur.

Critical information gaps that are hindering this process include the uncertain stock structure of Eastern School Whiting, mixed species composition of whiting in northern NSW and representativeness of biological parameters currently used in the joint stock assessment. This collaborative project between Commonwealth and state agencies aims to fill these information gaps using state-of-the-art scientific methods to increase confidence in stock assessment outputs and help develop appropriate cross-jurisdictional management arrangements.

Objectives

1. To clarify the stock structure of Eastern School Whiting in south-eastern Australian waters using a range of modern methods.
2. Investigate the spatial and temporal variation in the main biological parameters (length and age structures, growth and reproductive biology) of Eastern School Whiting across the species’ distribution.
3. Investigate the species composition of mixed trawl whiting catches in northern NSW to improve the quality of state catch data used in stock assessments.
4. Explore the effects of the findings from the first three objectives on the outputs of an updated Tier 1 stock assessment for Eastern School Whiting.

Improving and promoting fish-trawl selectivity in the Commonwealth Trawl Sector (CTS) and Great Australian Bight Trawl Sector (GABTS) of the Southern and Eastern Scalefish and Shark Fishery (SESSF)

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.
