Need

3D Marine seismic surveys (MSS) are typically used by the petroleum industry to locate potential oil and gas deposits. In Australia, the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) requires an Environmental Plan (EP) be developed to demonstrate that the MSS will be carried out in a manner that is consistent with the principles of ecologically sustainable development, and that the environmental impacts and risks associated with the MSS will be reduced to as low as reasonably practicable. However, during the public consultation phase of the EP, there is often a perceived conflict between the proponents of the survey and the fishing industry, with the later party often concerned that the survey will harm the fishery stocks and their livelihoods. As such, there is a need to break the continual cycle where each EP seemingly triggers the same ill feeling and distrust from the fishing industry. One possible way to do this is to introduce new seismic sources or ways of using current sources, such that some or all of the potential impacts are mitigated. While there are new seismic sources and source designs that should lessen any impact on animals, these have not been tested with animals anywhere in the world and have never been tested or used in Australia in general and only sparsely overseas. As such there is an urgent need to compare a current industry standard seismic array to arrays using alternate sources of seismic signals or different source designs to determine the relative impact of each on marine animals, while also comparing the quality of the geophysical records obtained from each source. This approach would put Australian fisheries management, NOPSEMA, Australian Oil and Gas, the fishing industry, etc. ahead of the game of determining what alternate sources will reduce conflict between two key industries. It would also move us into a position to start mitigating the impacts of seismic surveys, rather than the situation we currently have, where each individual seismic survey causes a large amount of angst between a large number of stake holders.

Objectives

1. Compare standard and alterative seismic sources
2. Determine the impact of each seismic source on Pecten fumatus
3. Determine the impact of each seismic source on Jasus edwardsii
4. Relative impact and threshold distances of each seismic source

Need

There are no antimicrobials permitted or registered for use in finfish in Australia effective against gram positive bacteria (e.g. Streptococcus and Lactococcus). In finfish aquaculture, erythromycin (ERYC) is the best antimicrobial against gram positive organisms. The aquaculture industry and the Subcommittee for Aquatic Animal Health identified access to this product for finfinfish as a priority. Bacterial diseases are increasingly managed by eradication, maintenance of animals of specified health status, vaccination, and good hygiene, but antimicrobial therapy remains vital for treating bacterial diseases in finfish aquaculture. Appropriate use of antimicrobials can alleviate illness and suffering, improve welfare, increase speed of recovery, reduce spread of infection. Use of ERYC is not intended for prophylactic treatment, but as a tool for veterinarians to manage disease outbreaks. Use in South Australia, for example, is sporadic (~1 to 2 times per 3-5 years for a sector). The Aquaculture industry is committed to Australia's antimicrobial strategy, and as required by APVMA this proposal includes an antimicrobial resistance risk assessment. Available data for ERYC can satisfy the APVMA module requirements for efficacy, chemistry and manufacture, toxicology, trade and occupational health and safety. These are available in published literature, a range of industry studies of animals treated off-label and laboratory studies. There is a lack of data to satisfy the requirements mainly in the environment modules and the antimicrobial resistance risk assessment.

ERYC was ranked low by the Expert Advisory Group on Antimicrobial Assessment (EAGAR) as an antimicrobial for which there are a reasonable number of alternative agents in different classes available to treat most infections. Although it is listed on the WHO list of essential medicines, it is registered for use in cattle, pigs and sheep (APVMA #84160) and poultry (APVMA #50742) in Australia and the WHO list can be modified locally to suit the availability and sophistication of the animal and human health systems in WHO member countries. The APVMA PAA assessed ERYC as suitable for assessment for use in finfish.

Objectives

1. Obtain data to satisfy identified gaps and collate available data to satisfy requirements of minor use permit application.
2. Collate and submit minor use permit application.

Water disinfection for influent water biosecurity on prawn grow-out farms

Project number: 2021-026
Project Status:
Current
Budget expenditure: $125,430.00

FRDC

Need

• Coping with the potential persistence of WSSV in Australian waters
It is important for farms in the WSD risk region, as well as those outside it, to have access to the necessary tools and reliable information that enables them to implement highly effective biosecurity measures when they become necessary.

• Industry white spot disease preparedness
Chemical treatment to remove residual vectors and/or destroy the pathogen is currently the only practical approach with potential to adequately reduce WSD biosecurity risk associated with influent farm water. When assessment indicates a high disease risk, farms will need to be confident that their biosecurity measures will be immediately effective.

• Appropriate guidelines for using trichlorfon
Currently there is no locally generated guideline for achieving effective application of trichlorfon that is based on directly applicable experimental data and prawn farm experience. The industry needs a set of guidelines that expand upon the basic APVMA use conditions and define the environmental factors and application parameters that will provide the greatest protection for Australian farm conditions.

• Gaps in information currently available
The available information does not provide substantiated details of trichlorfon treatment methods and outcomes. The Australian industry needs validated treatment methods and their effectiveness and biosecurity outcomes verified.

• Constraints on trichlorfon use during production
Using trichlorfon to treat top-up and exchange water during the production cycle is problematic for some farms due to the 12 day conditioning period required to ensure toxic residues are below the detectable limit before stock is exposed to the water. The potential to manipulate water quality parameters to accelerate residue degradation could make treatment throughout the cycle a more practical option.

• Continuation of permit to use trichlorfon
Documented evidence of outcomes and impacts of trichlorfon use on farms is needed to support an APVMA application to extend its use beyond the current MUP period ending 31 December 2021.

Objectives

1. Determine the efficacy of trichlorfon treatment for removal of crustaceans from farm influent water, and the rate of toxic residuals degradation, under a range of treatment circumstances experienced on prawn farms.
2. Provide the prawn grow-out sector with a practical guide for the optimal use of trichlorfon as a water biosecurity method.
3. Provide data for APVMA registration of trichlorfon use, including practical methods for reducing the withholding period for trichlorfon treated water.

Need

The ability of fisheries managers to control for sustainable harvest and reduce risks of fisheries overexploitation depends largely on an understanding of biological stock structure and recruitment dynamics. This information is critical for understanding the resilience of individual fishing stocks to fishing pressure and environmental disturbance, and the potential for stock replenishment through natural recruitment processes. At present this information is lacking for Australian giant crab (P. gigas) and giant spider crab (L. gaimardii) fisheries.

New opportunities have emerged that greatly enhance our ability to characterise patterns of biological stock structure in fine detail. Modern genomic technologies now allow for rapid and cost-effective assessments of genome wide variation within and between natural populations, allowing for spatial patterns of genetic structure to be characterised with unprecedented sensitivity. Additionally, advances in modelling capabilities are now allowing the unique integration of biological and physical oceanographic data to develop high-resolution models of larval dispersal in complex marine environments. Combining these new tools with traditional methods, such as stable isotopes and acoustic telemetry, provides a unique opportunity to undertake better assessments of biological stock structure and dynamics by accounting for both adult and juvenile dispersal stages.

Our team will leverage existing partnerships with industry stakeholders to undertake a comprehensive assessment of biological stock structure in the P. gigas and L. gaimardii fisheries. We proposed to adopt a multidisciplinary research program that will help to define the geographic boundaries of biological populations and the recruitment potential of individual fishing stocks. Outputs from this project will provide managers with a resource for establishing sustainable management programs in these fisheries that account for patterns of stock connectivity and the sensitivities of individual stocks to environmental disturbance and fishing pressure.

Objectives

1. Produce a regional map showing giant crab and giant spider crab biological stock structure and population connectivity (i.e., dispersal pathways)
2. Identify key stocks of giant crab and giant spider crab across Southern Australia that are major larval sources and well connected, whose careful management can facilitate greater resilience in the fishery
3. Provide a set of management recommendations based on our research findings that will promote more informed and sustainable fishing practices

Need

From call:

To effectively implement the new legislative requirements and Commonwealth fisheries resource sharing framework, the Commonwealth is seeking to develop an appropriate ‘Indigenous engagement strategy’. This engagement strategy will also be relevant for other Australian jurisdictions. The Department of Agriculture, Water and the Environment (DAWE) and the Australian Fisheries Management Authority (AFMA) are key stakeholders in this work and will have significant input. It is also envisaged that the Australian Fisheries Management Forum (AFMF), comprised of the Directors of Fisheries in each jurisdiction and the Commonwealth and its Indigenous subcommittee will be kept abreast and engaged regarding the research outputs.

Objectives

1. To develop a strategy to guide effective engagement between Indigenous fishing interests and management agencies responsible for Commonwealth fisheries, and with applicability to appropriate state and local level processes.

Need

Australian Standards have status and are recognised as best practice, but are not legal documents. However, a Government can reference a standard in legislation and it becomes mandatory.
AS 5300 is not yet mandated in Australia, but is listed in the FSANZ Standard 2.2.3 - Fish and Fish Products as an advisory note (https://www.legislation.gov.au/Details/F2011C00569 ) and AS 5301, is not reference anywhere.

Both SRB's recognise and industry stakeholder groups, recognise the standards must be mandated within FSANZ or other appropriate legislation. It is key that legislation covers the complete supply chain including food service, for the Standards to become fully effective. Further communication and extension of the required to support better adoption. Through this project, we will continue to articulate the need for the standards to become consumer law, whilst also advocating for further industry adoption of the standards.

The use of standard names achieves outcomes that are consistent with the aims of the seafood industry and Government:
1. Improved monitoring and stock assessment enhances the sustainability of fisheries resources.
2. Increased consistency and efficiency in seafood marketing to improve consumer confidence and industry profitability.
3. Improved accuracy and consistency in trade descriptions enables consumers to make more informed choices when purchasing seafood and reduces the potential for misleading and deceptive conduct.
4. More efficient management of seafood related public health incidents and food safety through improved labelling and species identification.

FNC undertook a stakeholder survey (Attachment1), with the key net benefits considered to be: consistency, integrity, transparency, improved management of food fraud and food safety and strengthening public, consumer and stakeholder confidence of the industry. These net benefits align with the FRDC's Fish forever 2030 vision and R & D Plan 2020-25; with strong relevance to Strategy V: Provide foundational information and support services; and Outcome 5: Community, trust, respect and value.
Attachment 2 & 3: Letters of support and net benefits summary show for further support of the Standards.

Objectives

1. To improve the content and relevance of AS 5300 and AS 5301 including underlying procedures to meet market, regulator and stakeholder needs and expectations.
2. To develop communication and extension plans for enhancing the understanding and use of the Standards for relevant stakeholders.
3. Implement and deliver communication and extension plans in collaboration with FRDC communications team to the key stakeholders, other FRDC services, broader seafood industry, government and other relevant users for increased uptake and use of AS 5300 and AS 5301.
4. To explore and develop opportunities to create efficiencies in administrating the Fish Names and Aquatic Plant Names SRB's.
5. Meet audit requirements for maintaining both AS 5300 and AS 5301 accreditation.

Stable isotopes: a rapid method to determine lobster diet and trace lobster origin?

Project number: 2021-020
Project Status:

Principal Investigator: John P. Keane
Organisation: University of Tasmania
Project start/end date: 30 Jun 2021 - 29 Jun 2022

FRDC

Need

1. Tracing lobster origin
The need for determining whether stable isotopes are a useful tool for diet analysis and identification of catch location is a priority for the SRL fishery. If proved useful, this technology will allow for rapid identification and isolation of stock abnormalities – such as toxic algal blooms, which has potential to save a lot of time and money for fisheries management.

2. Invasive urchin controls
If results show that small lobsters do predate on urchins, this will be important for informing stock rebuilding targets and reference points relative to urchin control. Primarily we could advise on whether urchin control targets and performance indicators should be based on total lobster biomass or only large lobster biomass. For example, if small lobsters (140mm CL) are found to actively predate on small urchins, the pressure to rebuild the large lobster biomass (>140mm CL) may be reduced. This could in turn help to adapt the rebuild strategy, in line with effective urchin control.

Objectives

1. To determine the level of stable isotope variation within individual lobster tissues (e.g. muscle vs shell) and identify a non-lethal and minimally destructive method of sampling for stable isotopes.
2. To describe lobster diet off eastern Tasmania and quantify the role of smaller lobsters (&lt
140mm CL) in the predation and control of Longspined Sea Urchin in Tasmania.
3. To ascertain if stable isotopes can be used to identify catch location of individual lobsters post-harvest across SE Australia

Need

Maintaining and enhancing market access for Australian seafood is critical for future industry survival and growth, particularly during and following the COVID-19 epidemic. SafeFish makes a significant contribution to this by carrying out the following:

1. Food safety incident response. SafeFish provides industry and government with immediate technical information required to respond to incidents relating to food safety and/or market access. Subsequently, technical input is provided to update policies for prevention of similar incidents and respond to them should they recur. Appropriate technical responses reduce the impact of food safety incidents and ensure better outcomes for future management.

2. Technical input to inter-government consultations on food regulations and market access. It is essential for the Australian seafood industry to participate in consultations such as Codex and monitor top export destination regulatory changes through WTO SPS notifications to ensure that proposed new, or modified, regulations are pragmatic and cost-effective for the Australian seafood industry. It is far easier to influence standards under development than after they have been finalised. Similarly, it is essential for the seafood industry to stay in close contact with Food Standards Australia and New Zealand (FSANZ) when domestic food safety regulations are reviewed.

3. Proactive research, risk analyses and training. The safety of Australian seafood is not negotiable in domestic and international markets. Over recent years SafeFish has conducted many activities to assist the industry anticipate and minimize food safety risks. The objective of these activities has always been to identify and mitigate risks before they cause a problem, or to grow knowledge to enable us to improve our risk management in a cost effective manner.

Objectives

1. To deliver robust food safety research and advice to industry and regulators that underpins Australia's reputation as a producer of safe seafood
2. To maintain and enhance the capabilities in Australia to provide that research and advice in a cost effective, efficient and timely manner.
