Need

Energy efficiency is a vital issue for Australian Fisheries with the prawn trawling industry being marginally profitable given present fuel prices. Further increases in fuel prices will cause many prawn trawling operators to become commercially unviable. For prawn trawling operations, 60% of the fuel consumed is whilst trawling (FRDC 2006/229), and the netting of the trawls is responsible for 60-80% of the towing drag (FRDC 2005/239). The results of previous and on-going projects show that prawn gear modification possesses significant potential for drag reduction.

Equally, it is important that prawn trawls produce “clean” catches with as little by-catch and benthic impact as possible. Devices to reduce by-catch and adverse benthic impact can however result in increased drag. Innovative design changes can therefore have conflicting outcomes. Resolution of this conflict, to establish trawl design principles that produce high performance with respect to flying shape and environmental impact is crucial to the future of the prawn trawling industry and is the challenge of the proposed project. The fundamental knowledge and methodologies established for prawn-trawling nets will also directly assist the process of optimising net drag for fish trawls to a significant extent.

Objectives

1. Systematically breakdown and understand the technical issues connected with the generation of drag by prawn trawls, and the competing needs of industry, to establish practical trawl improvements based on existing and new trawl design principles.
2. To optimise the shape and netting characteristics of a novel trawl design for prawn trawling with respect to lower drag and minimum environmental impact.
3. To predict the drag of prawn trawls based on net plan parameters and towing speed, accounting for twine orientation and the operational shape of the trawl.

Need

The Australian prawn wild catch sector has had significant decline with the financial crisis in Australia. The industry comprises of more than 1000 small businesses throughout Australia with little or no capacity to coordinate investment in and manage industry development. Recovering lost industry value and delivering future growth is contingent upon coordinated investment in industry development at the whole of industry level.

The ACPF is now established and well positioned with the CRC to implement its strategic plan and to integrate R&D work across all stakeholders under its leadership. Two distinct needs are involved in any consideration of better national R&D co-ordination for the prawn sector:
1. The strategic issues of R&D prioritization, funding and the linkages to (and support for) both industry development plans and Government objectives of industry development.
2. The operational issues of facilitating effective communication and coordination at all levels (industry/researchers, among researchers, among industry, FRDC and researchers, etc).

Objectives

1. To facilitate the prawn industry participation in Seafood CRC projects and the extension and utilization of the project results, particularly in relation to the development of new products and new markets.
2. To coordinate the planning, implementation, and reporting of R&D projects conducted by the Seafood CRC to achieve the outcomes specified in the ACPF Strategic Plan.
3. To establish, by December 2012, a mechanism by which the ACPF can fund its own R&D coordination and communication activities.

Summary

This project aimed to facilitate prawn industry participation in Seafood CRC projects and the extension and utilisation of the project results, particularly in relation to the development of new products and new markets. The planning, implementation and reporting of R&D projects conducted by the Seafood CRC was coordinated to achieve the outcomes specified in the ACPF Strategic Plan.

Selection of R&D projects to be undertaken by the Seafood CRC was determined by a Research Subcommittee established by the ACPF. The output of many early projects identified gaps and set priorities for subsequent research projects. The research and extension manager facilitated communication with the industry to encourage implementation and adoption of research outcomes.

The early projects identified these areas as having the greatest potential to provide enduring benefits for the Australian wild caught prawn industry were Value Chain Analysis, Quality Assurance and the National Prawn Marketing Strategy. These projects have breathed new life and enthusiasm into the industry. Through the uptake of the outcomes of these three areas of Seafood CRC projects, the outcomes of other lesser known Seafood CRC projects (such as nutritional profiles) are being disseminated and adopted by the industry.

Need

• There have been numerous trade failures regarding exportation of Australian prawns into Asia and Europe. These mainly relate to cadmium and Vibrios. ~4900 tonnes wild caught prawns were exported in 2007/2008 compared with total capture of 19,000 tonnes.

• Due to these trade issues the Seafood Access Forum have ranked Vibrios and cadmium as ‘high priority’.

• Vibrios have been responsible for illness outbreaks in Australia. Due to the role of Vibrios in illness outbreaks Codex is progressing standards on the control of Vibrios and domestic requirements for testing are increasing e.g. Woolworths requires testing for Vibrio cholerae.

• Standard laboratory methods are time consuming and don’t differentiate ‘disease-causing’ and ‘non-disease causing’ strains and so they ‘overscore’ (‘false positives’). The lack of this capability hampers efforts to dispute trade detentions related to the presence of Vibrios.

• This project aims to address this need by developing a rapid method that distinguishes pathogenic and non pathogenic V. parahaemolyticus, V. cholerae and V. vulnificus to underpin domestic and international trade requirements.

• Cadmium trade failures are related to the low maximum level set by the EU and some Chinese jurisdictions. Attempts by the Australian government have been unsuccessful in negotiating a higher limit.

• Recent data published on nutrients in food that may mitigate the adsorption of cadmium by humans has not been fully considered by regulatory authorities. Consideration of this may support the Codex position that no limit is required.

• This project aims to provide a risk-benefit assessment on cadmium in prawns to underpin further multi-lateral trade negotiations and Codex.

• Other potential food safety risks to the prawn industry will also be assessed and key areas of concern will be prioritised to assist in directing resources to issues of high business risk.

Objectives

1. Establish a recognised capacity to assist industry with domestic and international trade issues/failures related to V. parahaemolyticus, V. cholerae and V. vulnificus in prawns.
2. Generate data on levels of cadmium, iron, zinc, selenium and calcium in prawns to support risk-benefit assessment.
3. Undertake a scientific risk-benefit assessment on cadmium, iron, zinc, selenium and calcium in prawns to underpin future trade negotiations and support the Codex position that a standard is not required
4. Assess and rank the risks (food safety and trade related) to the prawn industry and prioritise key areas of concern to target risk reduction initiatives in the future.

Summary

Australia typically produces around 20,000 tonnes of prawns annually, of which around 25% is exported. The Australian Prawn Fisheries Council (APFC) and the Seafood CRC commissioned SARDI to undertake a food safety risk rating of prawns consumed in Australia. This project scientifically evaluated the human health impact of chemical and microbial hazards associated with prawns.

Risk ratings indicate a very low risk of human illness associated with the consumption of prawns produced domestically, imported prawns and exported prawns. This finding is consistent with the public health record which shows few reports of illness related to the consumption of prawns that have been handled appropriately

Need

The ACPF workshop identified the R&D Priority 2 – Quality Assurance Action item "Black spot project to be developed by SARDI/QDPI, in conjunction with the CRC"

There is a need to better define the issues surrounding the effective use of metabisulphite and 4-hexylresorcinol by the Australian Prawn Industry, and to refine the associated research requirements. This relates specifically to the reduction in dip effectiveness with successive dips and the development of on-boat dip concentration meter – a “metameter”.

Objectives

1. To determine the significance of melanisation (black spot) in prawns to poducers and processors
2. To assess the need for further research on metabisulphite dipping and on the development of a dip meter
3. To assess the need for further research on 4-hexylresorcinol dipping.

Summary

Summary:

The wild prawn capture industry is under increasing competition from imported and domestic aquaculture product. One problem facing the industry is the frequent occurrence of black pigment on the head and tail surfaces. This condition is known as black spot and can be prevented by treating the prawns with any of a number of different chemicals such as sodium metabisulphite.

This project aimed to 1) determine the significance of black spot in prawns to producers and processors 2) assess the need for further research on metabisulphite dipping and on the development of a dip meter and 3) assess the need for further research on 4-hexylresorcinol dipping.

A questionnaire was developed for industry members to complete. Interviews were conducted mostly in person or by phone with wild capture prawn industry members in various prawn fisheries around Australia. The results showed that the black spot issues varied with each fishery and that sodium metabisulphite was the chemical of choice for preventing black spot in the wild prawn fishing industry. There were many different ways this chemical was applied but the fishers did not always have the confidence that they were using it effectively.

The planned outcomes and benefits of this project were the identification of issues surrounding metabisulphite and 4-hexylresorcinol use and efficiency in the Australian Prawn fishery, including shelf-life and market perception. The survey identified that fishers are not sure which dip methods were effective for the various prawn fisheries. Research and training would provide them with the latest details on what chemical to use and how to use them. Additionally, easy to use sensor and test methods would ensure that sufficient residue of chemicals are present in the product so that it will be protected while being handled by retailers and consumers.

Need

Individuals/organisations that would benefit from the program with Nofima are those that are:

1. considering starting selective breeding programs or supplying industry with hatchery stock (as many as 10 industry associations or groups of farms)

2. analysing data and making decisions about the selection and mating of selectively bred stock (as many as 10 genetics service providers, private or public)

3. involved with the day-to-day operation of a nucleus or hatchery (includes many hatchery managers)

4. trying to run a profitable selective breeding or hatchery business (eg. managers or owners of companies such as Australian Seafood Industries PL for Pacific Oyster or Saltas PL for Atlantic Salmon)

Individuals/organisations in these interest groups have overlapping needs to some degree:

A. Need for owners, managers, geneticists and hatchery staff in Australia to be put in touch (network) with those having similar responsibilities in other sectors within Australia, as well as with international players in the selective breeding scene, so that they can benefit from the experience of existing research organisations and businesses.

B. Australia's reputation, isolation and environment could make it an attractive source of selectively bred stock internationally. Therefore there is an opportunity for some breeding programs to supply overseas producers with genetically improved stock. But there is a need to understand how such a business might operate and how risks can be managed.

C. Need for those analysing data and making decisions about the selection and mating of selectively bred stock, and involved with the day-to-day operation of a nucleus or hatchery, to be informed of the latest technical developments overseas and how developments might be adopted to benefit Australian breeding companies and aquaculture industries.

D. Need for improving basic knowledge about establishing, running and profiting from selective breeding.

Objectives

1. To give owners, managers, geneticists and hatchery staff involved with selective breeding programs in Australia short-term exposure to facilitate the establishment of dialogue, cooperation and/or collaboration with international players on the selective breeding scene
2. To directly educate and inform scientists making decisions about selection and mating (at least one person for each aquaculture industry participating in the Seafood CRC) and those involved with the day-to-day operation of the nucleus or hatchery about the latest technical developments overseas and how these might be adapted within Australia
3. To improve basic knowledge about establishing, running and profiting from selective breeding leading to implementation of significant and recognisable improvements in breeding programs towards world’s best practice (on average at least one improvement per sector)

Summary

A number of businesses have recently been established in Australia with a primary focus on genetic improvement and the sale of genetically improved stock for aquaculture. The production of selectively bred stock has been shown to have high benefit-cost, even for relatively small aquaculture industries, and so a number of new breeding programs (companies or cooperatives) are likely to begin operation during the life of the Seafood CRC. Selective breeding is highly technical so that even the hands-on running of a breeding nucleus requires a high degree of specialist training. The business of selective breeding is relatively new in Australia and there is much to be learnt from experiences overseas.

The Seafood CRC believes Australian breeders could learn a lot from the experience of Nofima who have been providing genetic and breeding research services directly to breeding programs around the world for more than 30 years and who have established programs for Atlantic Salmon, Rainbow Trout, Atlantic Cod, Tilapia and other species that are now commercialised and recognised internationally.

This exchange program will benefit aquaculturists who are considering starting selective breeding programs or hatcheries to supply industry with stock and assistance with analysing data and making decisions about the selection and mating of selectively bred stock. The exchange program also will assist with the day-to-day operation of a nucleus or hatchery and those trying to run a profitable selective breeding or hatchery business

The program will also give owners, managers, geneticists and hatchery staff involved with selective breeding programs in Australia the opportunity to establish dialogue, cooperation and/or collaboration with international players on the selective breeding scene and Nofima can provide an insight into the development, strategies and running of successful international selective breeding businesses. Lastly, the exchange will help to educate those making decisions about selection and mating and will provide the latest technical developments overseas and how these might be adapted within Australia, whilst improving their basic knowledge about establishing, running and profiting from selective breeding.

Need

Australia cannot successfully compete on national or international commodity seafood markets. Comparatively low volumes and relatively high cost of labour mean that cheap imported prawns (among other seafood products) are favoured by Australian consumers. Yet Australia produces demonstrably superior seafood from sustainably managed fisheries compliant with principles of ecological sustainable development. There is an opportunity and indeed a need to develop and maintain niche markets reflecting a defensible value proposition of quality, safety, and sustainability. There is a need to improve supply chain management to improve product quality and to capture greater efficiency thereby leading to increased profitability. There is a clear need to improve profitability to maintain the viability of the Queensland (and Australian) prawn industry: a need which can be addressed by improving margins and by clearly differentiating Queensland prawns against similar commodity products.

In following the template established by the Clean Green rock lobster program, a clear route to adoption is presented. In the case of Clean rock lobster, research and development activities leading to successful premium market penetration took some ten years. The proposed project will build on this successful integrated product management system in developing auditable workplace standards and reinforcing best practice throughout the supply chain to position Queensland prawns as demonstrably superior. In this way a proactive approach to building consumer awareness of the quality of Queensland prawns will yield the desired economic and social outcomes.

This relates to identified FRDC strategies of incorporating a whole of supply chain approach, including a consumer perspective, to improve value, quality and perceptions. Importantly, the project also targets industry profitably by improving market access and competing more effectively in global seafood markets.

Objectives

1. Conduct a gap analysis of existing work practices against premium product standards with an emphasis on food safety, product quality, environmental sustainability and occupational health and safety
2. Develop a business plan based on identified costs and benefits for implementation of the Clean Green integrated product management system
3. Assess the viability of the business plan through consultation with the Queensland wild catch prawn sector

Need

International markets are being overwhelmed by the production of prawns from aquaculture and there is no credible marketing approach from the wild-caught prawn fisheries to this threat. In addition, markets are increasing their demands for accreditation of fishing practices from supplier countries and fisheries. There is a need to develop a national coordinated approach to this issue and for fisheries have the chance to have real input on how these threats will be addressed.

A prawn workshop will provide an opportunity for fishers around the country to get together and discuss the strengths, weaknesses, opportunities and threats of their prawn products. The key theme of the workshop will be marketing and promotion. This will stimulate thinking bout the gaps in marketing at activities both at the national, state and local levels and will encourage fishers to exchange ideas about how to overcome the marketing and promotion gaps. An identification of what is needed over the next 2 to 5 years in terms of who, what, where and why for marketing will provide a clear mandate to the Australian Council of Prawn Fisheries.

This forum will also strengthen the prawn fisheries network across Australia through networking and the sharing of information. The development of an action plan will provide a tangible outcome from the forum.

Objectives

1. To deliver a national prawn fisheries workshop building on the first National Prawn Fisheries Conference
2. To support the establishment of the Australian Council of Prawn Fisheries to advance the prawn industry at a national level
3. To strengthen networks between Australia's prawn fisheries
4. To provide an opportunity for industry members to work together in problem solving the national issues relevant to marketing and promotion of prawn product and to commence implementation of an industry action plan

Summary

Australia comprises fifteen different prawn fisheries across Australia with a combined value at close to $1billion in gross revenue.  A look at several other Australian fisheries showed that those that had been successful at addressing issues at a national level had national representative organisations that complemented State-based associations.  It was clear that fishery-specific conferences had provided an incentive for stakeholders to come together to investigate the issues and develop appropriate, coordinated responses.  Development of national representative bodies became a logical next step.  

In 2004, it was clear that the prawn industry did not have a national forum through which national issues could be discussed and national responses developed.  In the absence of such forums, responses were ad hoc at best and in many cases no effective responses were being developed or delivered by the industry.  The National Prawn Fisheries Conference held in Cairns in November 2004 connected people across the industry.

Following the 2004 conference, four wild-catch prawn industry organisations provided funding to develop a draft strategic plan for the next 10 years and further funding was leveraged by the Federal Government to invest in assessing the challenges and opportunities for the industry. The Taking Stock and Setting Directions report became the basis of developing a draft strategic plan for the industry.  The report clearly identified that a sustainable and profitable pathway for the industry was achievable. A draft strategic plan was developed by the Australian Council of Prawn Fisheries. The conference became the forum to obtain industry’s comments on the strategies in the strategic plan. 

The Spencer Gulf and West Coast Prawn Fishermen’s Association agreed to host the Second National Prawn Fisheries Conference to strengthen the networks between people in the various prawn fisheries and to support the new national body.

The conference was specifically designed to give direction to the Australian Council of Prawn Fisheries on the priority projects to be pursued under the draft strategic plan.  An event manager was contracted to manage the logistics and a professional facilitator contracted to ensure that specific outcomes were obtained and that all delegates were provided opportunity to have input.  Information was provided on each theme by invited guest speakers and these sessions were followed by facilitated, interactive discussion among all delegates.
