Identification of muscle parasite in Yellowtail Kingfish (Seriola lalandi) and Mahi Mahi (Coryphaena hippurus), and determination as to the efficacy of non-invasive screening technology for the purpose of identifying infected fish in a commercial fish processing environment
Growing a profitable, innovative and collaborative Australian Yellowtail Kingfish aquaculture industry: bringing 'white' fish to the market - RnD4Profit-14-01-027 - SA Component
YTK farming is identified nationally as the greatest opportunity for new aquaculture development in the next few decades through substantial increases in farmed area and product, and use of aquafeeds, resulting in growth in regional economies and employment. Within 10 years, YTK production is expected to increase by 34,000 tonnes, worth $440 million, and using 68,000 tonnes of aquafeed worth $136 million. The key challenge to achieving this growth is for industry to diversify its focus from supplying only the relatively small volume, high price sashimi market to the larger volume, lower price Australian ‘white fish’ market, while enhancing farm productivity and reducing operating costs to maintain profitability.
This project will enable industry to grow its position by developing more cost effective, sustainable feeds and feeding strategies to enhance YTK growth and health; the industry’s highest common R&D priorities as feed and feeding strategies comprise 60% of operating costs. It will also network three key Australian YTK aquaculture companies and their aligned research institutions (SA, NSW and WA). Aquafeed companies are also likely to participate. As such, this project will meet the designated ‘Rural Research & Development for Profit Programme’ objectives:
1. “Generating knowledge, technologies, products or processes that benefit primary producers",
2. “Establishing and fostering industry and research collaborations that form the basis for ongoing innovation and growth of Australian agriculture”.
The key Activities wil address the YTK industry's common R&D priorities through three components/themes:
1. Economically sustainable feeds and improved diet formulation (NUTRITION);
2. Improved FEEDING STRATEGIES to increase profit; and
3. Improving nutritional HEALTH to boost productivity.
Once the project is initiated the Steering Committee will develop an agreed approach to engage with aquafeed companies to maximise participation in and contribution to the project.

Identification of demand drivers, distribution requirements and supply chain efficiencies to assist development of the Hiramasa Kingfish ™ (Seriola lalandi) and Suzuki Mulloway ™ (Argyrosomus hololepidotus) brands in Melbourne
It is critical that this industry:
·Increases demand domestically and overseas, but increases supply in ine with demand.
·Identifies what drives customer demand.
·Iidentifies how to consistently meet these key drivers.
·Identifies the appropriate anatomy of its brands in Australia and overseas.
·Identifies enterprise and sectoral brand standards and certification processes which customers value at the “bottom of the pyramid” which could articulate with a draft National Aquaculture Brand developed at the “top of the pyramid”.
This project is critical as a starting point for the SA Marine Finfish industry. This industry needs to establish brands which command a premium price. Therefore, it needs to know what niche markets value in terms of supply, safety and quality, and establish a brand "anatomy" which reflects those requirements. It must also determine the best way to promote the "anatomy" and provide the required product and supporting information to customers.
The National Aquaculture Council project has so far undertaken generic attitude surveys covering customer preferences for aquaculture product to be eaten at home (via supermarkets) or in restaurants.
Initial results show that Hiramsa Kingfish and Suzuki Mulloway are hardly known in the Melbourne fine dining market. Some responses to the initial National Aquaculture Council research need to be followed up in more detail for our products, as respondents appear to be either unaware of our products, or have misconceptions about them.
For example:
One potential driver of demand is “appealing taste”. The responses to the NAC project scored Barramundi much more highly than “Kingfish”. It is not clear why this is so, and whether respondents differentiated wild kingfish from our branded product.
“Familiarity and availability” also appears to be key drivers. Again “kingfish" scores far below all other aquaculture finfish products.
“Healthy and nutritious” also appear to be drivers, but potential customers appear to have little understanding of the benefits of our branded product.
“Low fat content” appears to be driver, but presumably customers are referring only to saturated fats. (However, Omega 3 and 6 is part of the fat content).
Indicators of “freshness” and “quality” need to be objectively defined.
“Affordability” is another driver, which will be directly impacted by market positioning.
There also appears to be a relationship between the demand for seafood product as a special dining experience (value added) as opposed to its comparative availability as a supermarket commodity. This needs to be clarified as it may affect the brand "anatomy" relating to different market segments.
Therefore, Hiramsa Kingfish ™ and Suzuki Mulloway™ products need to build a brand “anatomy” which is appropriate to the Melbourne domestic market and can justify the brand claims, in terms of:
Features (e.g. omega content etc); Functional Benefits (taste, texture etc); Emotional Benefits (luxurious, special treat, clean and green, guilt free); Personality (social eating, entertainment, fashion) , Values (healthy living, safe etc), and Soul (essence of the brand – eg. Australian quality, supporting human health and environment health).
However, different aquaculture products will have different “anatomies” which need to be separately identified for different products and different markets.
A National Aquaculture Brand may have a generic “anatomy”.
It is appropriate to first undertake this research in the domestic market and establish the domestic “anatomy” and supporting supply structure, promotional strategy and materials. This will form the basis of “export readiness”, prior to researching and developing overseas markets, which may require an “anatomy” appropriate to each market.
However, there is an urgency to complete this domestic project and use the research findings as the basis for further export research. (FRDC will note that Australia’s seafood export earnings were down 11% in 2002/2003 but aquaculture’s value rose by 1.5% despite lower export returns for species such as tuna and salmon). Austrade Los Angeles wishes to urgently promote Australian seafood, and we therefore have to be prepared.
Final report
Identification and management of potential food safety issues in aquaculture-produced yellowtail kingfish (Seriola lalandi)
Priorities for future industry research programs need to be developed to demonstrate food safety requirements are being met.
As part of the YTKF development, food safety is identified as a high priority in the Yellowtail Kingfish Aquaculture Strategic Research and Development Plan 2003-2008. Specific food safety issues for the Industry to address to support its sustainable development include:
- Longer feeding cycles for Yellowtail Kingfish.
- Multiple market weights for Yellowtail Kingfish.
- Multiple markets for Yellowtail Kingfish, hence multiple residue standards.
- Multiple and mixed origins of feed components for Yellowtail Kingfish aquafeeds.
At the 35th session of the Codex Committee on Food Additives and Contaminants being held in March in Tanzania the issue of setting of Maximum Limits (MLs) for farmed fish and aquafeeds is being discussed. Many of the YTKF markets are Codex Alimentarius Member Nations. At this meeting data will be presented on dioxin levels in fish meal/oil, binders, anti-caking agents, anticoagulants, trace elements, macro minerals and pre-mixes.
The EU has set a Maximum Level (NL) for dioxin in muscle meat of fish and fishery products and products at 4 pg WHO-PCDD/F-TEQ/g fresh weight. On or before 2006 this ML for dioxin will be reduced significantly, and may be converted to a fat weight basis ML in line with all other EU commodity MLs that have been set for dioxin.
For manufactured aquafeeds the EU has set a dioxin ML of 2.25 ng WHO-PCDD/F-TEQ//kg (relative to a moisture content of 12%), under Council Directive 2001/102/EC. Currently levels in South American sourced products are one tenth of those levels found in European sourced products.
Codex have stressed the importance of examining the transfer and retention of individual dioxin congeners from feed to food producing animals (ie fish) not total dioxin alone. Stochastic Monte Carlo predictive modelling options could be considered to address this.
Japan and Australia have adopted dioxin standards based on dietary modelling, setting a Tolerable Daily Intake (TDI) for the whole diet.
FSANZ is currently undertaking a dioxin survey of Australian foods including seafood.
Environment Australia as part of the National Dioxins Program, in conjunction with the National Residue Survey is undertaking a national survey of dioxin levels in a variety of foods, native animals, plants and aquatic biota.
Under European Union Commission Regulation (EC) No 466/2001 "Setting maximum levels for certain contaminants in foodstuffs", a Maximum Level (ML) for lead in muscle tissue of fish of 0.2 mg/kg is in force.
Codex Alimentarius is considering reducing the Maximum Limit (ML) for lead (Pb) from 0.5 mg/kg to 0.2 mg/kg in fish muscle tissue.
Under EU Commission Regulation (EC) No 466/2001 of 8 March 2001 "Setting maximum levels for certain contaminants in foodstuffs", a ML has been set for cadmium in fish. Australia does not have a ML for cadmium in fish under the FSANZ Food Code.
The US Congress is currently considering reducing the ML for mercury in fish.
Singapore's Agri-Food & Veterinary Authority administers the "Sale of Food Act" & "Food Regulations" which govern residue MLs for trade.
Final report
Hazards such as dioxin (PCDD/F) and PCBs have been identified in manufactured feeds as priorities for further investigation by industry. These issues are now being discussed by the South Australian Marine Finfish Farmers Association Inc (SAMFFA) and Australian feed manufacturers as part of developing a feed quality assurance scheme.
Information has been provided to growers on traceability requirements in overseas markets. There is a need to capture information being collected by multiple sources along the production chain into a single traceability system.
Data collected within this project was used to satisfy formal EU product integrity market access requirements (managed by DAFF) for YTKF and Mulloway in 2003 & 2004. DAFF is also examining feed data collected within this project as part of the development of national residue for residues in aquaculture feeding materials.
All test results fully met official standards set by Food Standards Australia New Zealand (FSANZ) within the Australia New Zealand Food Standards Code, the Japanese Ministry of Health, Labour and Welfare within the Food Sanitation Law, Codex Alimentarius Commission, United States Food and Drug Administration (FDA) and the European Commission (EC).
