Improved understanding of Tasmanian harmful algal blooms and biotoxin events to support seafood risk management

The 2012 Tasmanian biotoxin event represents a paradigm shift for seafood risk management in Tasmania and Australia as a whole. The causative dinoflagellates are extremely difficult to identify by routine plankton monitoring, and are toxic at very low cell concentrations (50-100 cells/L). Sampling...

Need

The salmonid aquaculture industry is worth about $400 million to the Tasmanian economy and directly employs over 1200 people. This industry has plans to double production by 2030, which will require finding new localities for farms that are conducive to large scale production. Storm Bay has been identified as a potential growth area and baseline environmental data are essential to inform site selection and for future assessments of any effects of salmon production on the Storm Bay environment, i.e. ensuring the industry is sustainable. Concomitant with this development is the need to establish social acceptability and to meet public expectations of a sustainable industry; this project will provide the baseline data necessary to support these requirements.

Information to be provided by this project on changing environmental conditions such as temperature, salinity and nutrients, and concentrations of planktonic organisms harmful to salmon production, such as HABs and jellyfish, which are related to changing weather patterns and current flows, are also very important to farm management, especially to risk assessments underpinning Decision Support Systems. Specifically, the project will ensure a thorough understanding of how major water masses interact in Storm Bay to influence nutrient flux, algal dynamics and responses of key plankton, including HABs and jellyfish.

Objectives

1. Build on available data to establish baseline environmental conditions in southeastern Tasmanian coastal waters to support informed expansion of finfish farming in this region.
2. Enhance risk assessments underpinning Decision Support Systems for effects of changing weather and current patterns on water temperature, nutrients and plankton, especially in relation to HABs and gelatinous zooplankton.
3. Trial and establish a screening program for Neoparamoeba perurans, the causative agent of AGD.
4. Obtain measurements of primary productivity in Storm Bay and link to environmental drivers.

Need

The House of Representatives inquiry ‘Netting the benefits’ (November 2012) recommended that ‘the Australian Government continue to publish a consolidated stock report for all Australian fisheries with the consultation of State and Territory governments’. The Australian Government’s State of the Environment Report 2011 also identified that a ‘lack of a nationally integrated approach inhibits effective marine management’. In addition to the Australia’s domestic reporting responsibilities, national stock status reports are also required to inform the broader international community.

The inaugural SAFS reports (2012) demonstrated the value and impact of national reporting, providing an easy to access, consistent national picture of wild-capture fish stock sustainability. The SAFS reports 2014 would continue to provide consistent national comparisons, for an increased number of species.

To establish a strategic, longer-term plan and ensure the SAFS reports remain on-going it will be important to develop processes for self-sustainment. On-going support (personnel and funding) from all jurisdictions is critical to this. Some jurisdictions have already adopted aspects of the agreed national reporting framework, which will support improved alignment between jurisdictional reports and simplify production of future SAFS reports. The current proposal is critical to ensuring production of a high quality second edition. Throughout this project processes will be established for the self-sustainment of national fisheries status reporting.

There is also a need for national reporting on additional aspects of fisheries Ecologically Sustainable Development (ESD). This was highlighted in the House of Representatives inquiry (2012) which supported the inclusion of detailed ecosystem sustainability issues in future national reports.

Objectives

1. To produce a second edition of the Status of key Australian fish stocks reports in 2014
2. To review and update the SAFS reporting framework and production process for future editions of the SAFS reports
3. To commence work to improve technical issues associated with production of the SAFS reports (data acquisition, updating process, web format)
4. To commence work to develop frameworks and production processes for companion national fishery status reports which will include other aspects of ecologically sustainable development (ESD) of fisheries

Need

The FRDC released the Status of Key Australian Fish Stocks Reports in 2012 to provide a scientifically robust, simple tool to inform fishers, seafood consumers, managers, policy makers and the broader community about the stock status of key wild-caught fish stocks around Australia. This publication was prepared by the Australian Bureau of Agricultural and Resource Economics and Sciences, in collaboration with government fishery research agencies in all Australian jurisdictions with marine fisheries, an enormous task that involved cooperation from over 80 researchers.

The collation of data from 49 different species (or species complexes) from around Australia required cross-jurisdictional cooperation in determining assessments. This process highlighted the differences in data collected between agencies in terms of quality, quantity and format, which greatly increased the effort required to prepare the Reports.

The second edition of this series is being prepared during 2014, and it is anticipated that it will be repeated every second year. The effort and cost of producing the report could be significantly reduced if the data used to inform assessments was standardised across jurisdictions, and was readily available through a fisheries data portal. Further, making this data publically available through the website would allow the public to run their own queries, increasing transparency, reducing red tape and creating other efficiencies.

Before this can be done however, there is a need for greater understanding of the challenges involved in mapping fisheries data collected by different agencies. Given the large number of fisheries agencies around Australia, and the variety of data they collect and/or generate, this proposal is for a pilot study focusing on data collected by SA and NT, who have agreed to participate.

Objectives

1. Identify data collected by State, Commonwealth and other research agencies for each main South Australian and Northern Territory fish stock that is used to support the Status of Key Australian Fish Stocks Reports
2. Describe data sets identified including (but not limited to) assessment of data quality, fields collected, units, completeness, frequency of collection, privacy restrictions and storage format
2. Undertake Gap analysis of data collected for each stock and develop framework for rollout of project for all fish stocks in the Status of Key Australian Fish Stocks Reports

Need

Australia’s aquarium industries are high value (collectively GVP values >$20 million), small scale fisheries that rely on exporting CITES listed corals for profitability and viability. The Australian government requires fisheries collecting and exporting CITES listed species to demonstrate that their harvest is sustainable. This is achieved through the provision of a successful non-detrimental finding and accrediting the fishery as an approved Wildlife Trade Operation (WTO) under the EPBC Act. There is growing international pressure for Australia to unequivocally demonstrate sustainable collection practices for CITES listed species. However, data-poor fisheries like the aquarium fisheries, struggle to provide sufficient quantitative data supporting the non-detrimental use of CITES listed species. This has resulted in severe restrictions on allowable harvest levels tied to WTO approvals and industry viability is at risk.

Many of the coral species taken by the marine aquarium industry across northern Australia are in inter-reef turbid water environments that are poorly studied. In addition, many of the species are documented as rare or uncommon although they may be locally abundant in these turbid waters environments. A recent Ecological Risk Assessment of the Queensland Coral Fishery (May 2013) identified the priority need to fill these data gaps to better quantify the level of impact on corals from commercial collection.

Abundance baselines for these species are required to demonstrate sustainable use and support export approvals. Species identification of harvested corals also needs to be clarified as this information is critical for aligning catch data with scientific information on the vulnerability of different coral species. This will lead to the development of monitoring protocols for the industry, and in the longer term, to demonstrate sustainable harvest.

Objectives

1. Establish the distribution and abundance of commercially important coral species in selected inter-reef habitats
2. Improve the accuracy of species identifications across the industry
3. Establishing abundance and turnover of representative commercially important inter-reefal corals
4. Establish a cost effective industry based long-term monitoring program
5. Undertake consistent Ecological Risk Assessments (ERA) in NT and WA to establish vulnerability of major target species

Summary

The objectives and outcomes of this project were three-fold. Firstly, we established the abundance and turnover of select, commercially important coral species in areas of concentrated fishing across northern Australia. Improved understanding of the biology and ecology of harvested corals is fundamental to establishing baselines and sustainable harvest levels. Secondly, we helped to refine species-level taxonomy for commonly harvested coral species, using genetic analyses, to better establish what is being harvested and where. Genetic analyses on corals collected from different jurisdictions helped to reveal which species are very widespread, and therefore more resilient, versus those that are geographically restricted, and therefore warrant specific management attention. Thirdly, we explored species-specific vulnerability to extrinsic pressures on coral stocks, related to environmental change. Climate induced coral bleaching if the foremost threat to coral species and could undermine the sustainability of ongoing coral harvesting independent of fishery effort or take.
