Tasmanian Seafoods Pty. Ltd. aims to double the current production of sea cucumbers through ranching/stock enhancement initiatives. This commitment is demonstrated by the history of investment by TSF over the past 5 years. To ensure the commercial viability of this enterprise there are researchable constraints to be addressed. These are within the broodstock maintenance. Currently, hatchery production relies on the seasonal supply of ripe broodstock from pond facilities or the wild. Attempts to mature sandfish broodstock in tanks have so far been unsuccessful and broodstock held in tanks for periods of greater than one month have declined in condition (Morgan, 2000). Recently however, anecdotal evidence suggests that under the right conditions it is possible for adult sandfish to mature in tanks and be used for hatchery production of juvenile sandfish. Identifying the factors and requirements for the maturation of broodstock H. scabra in controlled systems could enable year round supply of eggs for hatchery production and reduce the seasonal constraints on juvenile supply for ranching and stock enhancement programs in the NT.
The success rates reported for induced spawning events for sandfish are low (0-35%) increasing around peak natural spawning times (Battaglene et al., 2002). This poses a significant economic constraint to the company’s aim to develop the capacity to produce 300,000 juveniles annually for release programs. Research into the molecular signalling and communication involved during spawning could improve induction efficiencies and may lead to the identification and development of a hormonal spawning inducer for sandfish.

Summary

This thesis reports on an investigation of brood stock conditioning methods for the tropical sea cucumber Holothuria scabra. The project aims to advance the field of sea cucumber aquaculture by developing improved methods for the conditioning and spawning of brood stock.

There is great demand for sea cucumber products and that has seen the aquaculture production of the temperate species Apostichopus japonicus increase dramatically in the last decade, surpassing capture fisheries production. This increase in aquaculture production has not been mirrored for tropical species despite established methods for hatchery production and a large market demand. With wild harvests of sea cucumber unlikely to increase there is an opportunity to develop a substantial sea cucumber aquaculture industry in Northern Australia.

Fat or oil content in fish is an economically important trait as it is one of the primary determinants of flesh quality and consumer perception of the end-product. The market value of a carcass or fillets, particularly of large species such as kingfish and tuna, can be strongly influenced by the percentage of fat in the tissues. Yet little is known about the heritability and genetics behind lipid deposition in YTK, and thus the current ability to select for and improve this highly marketable trait is limited. This research will address this deficiency by developing pedigree-based selection for flesh oil content and identifying, as well as quantifying, genes and gene expression associated with this trait.

Objectives

1. Data on the heritability of flesh oil content from twelve YTK families
2. Quantitative data of gene expression for genes associated with fat metabolism and deposition in YTK
3. Identification of novel genes associated with fat metabolism and deposition in YTK
4. Scientific publications in international journals of the above

Need

East Coast Trawl Fishery (ECTF) involves fishers, agent and/or wholesaler, processors, various industry and government organisations and retailers. The lack of collaboration and production activities due to the lengthy coast and long distance between trawl areas along with a multi species fishery has resulted in the fishery becoming (i) a production focused industry and (ii) location oriented rather than whole of state or whole of fishery oriented industry. Consequently, intense competition exists within East Coast Trawl throughout the whole supply and value chain. This has been exacerbated by the decline in the value of Queensland prawn production over the past five years caused by record high fuel costs; labour shortages; competition from imported product and the strong Australian dollar. Furthermore, ACPF have identified a whole of industry approach as a research priority with an objective to identify a specific opportunity/strategy to pursue, not as individual fishers, but as a collective fishery. This project aims to develop a framework and benchmark case study to identify the leadership qualities and commitment within the ECTF. The implementation of a market opportunity/strategy will assess the identified ECTF leadership group and the network’s ability to increase long term profitability for the fishery.
The industry has identified and agreed to the need to develop collaboration within the fishery to leverage existing and future market opportunities. The understanding and building of industry social capital to support internal leadership through a network analysis is seen as fundamental to the development, coordination and implementation of a market approach for the industry.

Objectives

1. The identification of a core leadership group and an understanding of the current industry network structure will provide a platform for building the social capital and associated network to improve collaboration, information and resource dissemination and more informed decisions. Establishing an effective Leadership group that will champion the industry and effectively utilise the network to can improve the industry’s ability to act proactively rather than reactively, enhance the reputation of the industry and provide positive socio-economic outcomes for the ECTF.
2. Trialling and evaluating a market development strategy will demonstrate how effectively the fishery network and the Leadership group are at working together to achieve a positive outcome. This will further highlight the strengths and weaknesses for ultimately building a robust network for identifying future opportunities and effectively responding to industry challenges.

Summary

The East Coast Trawl Fishery (ECTF) is spread over a large geographical area (from the Torres Strait to the Queensland/New South Wales border), and comprises a large number of small independent fishers. Importantly, it is one of Australia's largest fisheries and has an annual volume of 10,000 tonnes with a value of around $110million a year. This project aimed to investigate the current structure and process of the ECTF network. It was proposed that examining network structure and processes (in the context of social capital theory) was critical in identifying opportunities for both the ECTF network and individual fishers.

The investigation within the fishery revealed formal and informal leadership exists. Other types of leadership were identified including heroic and informal leaders. These forms of leadership aid in fishery connectivity and can be re-engaged to facilitate future fishery activities and decision making.

Several fishery market opportunities were evaluated and each brought fishery stakeholders together. This provided valuable insight into the fishery, stakeholder interaction, communication and the possible approaches for fishery stakeholders to address future collective actions.

SCRC: Alleviation of Summer Gut Syndrome (SGS) in Tasmanian Atlantic Salmon

Need

The prevalence of SGS and other gut-related diseases is a primary cause of economic losses related to the farming of Atlantic Salmon with AGD being more significant. Maricultured Atlantic salmon in Tasmanian south-eastern waters have been frequently noted to exhibit an increased mortality during summer due to SGS. The problem is of concern to the Tasmanian aquaculture industry due to reduction in production efficiency. The aetiology of the SGS is unidentified but the fact that antibiotics can resolve the problem temporarily suggests that SGS is induced by a bacterial agent or agents. Identification of the aetiology of the disease is therefore a priority to resolve the problem. This however, requires a detailed investigation of the dynamics of microbial communities in the gut and their response to environmental factors such as temperature and diet over time as well as investigating their interaction with the gut epithelium. This has to be done not only in salmon afflicted with SGS but also in healthy salmon to determine how the protective effect of normal microflora in salmon is compromised during warm seasons allowing overgrowth of certain species of bacteria. Previous research suggests SGS may be caused by the proliferation of apparently non-pathogenic species of Vibrios or Aliivibrios. This needs to be verified and we plan to investigate this as well as investigating pathogenic potential of all bacteria that establish a close contact with the gut epithelium of salmon over time. And finally the importance of probiotic strains with potential to competitively exclude pathogenic strains in salmon’s gut and their population dynamics requires investigation as these bacteria may have an important role in prevention of the SGS.

SCRC: Seafood CRC Master Class: Stimulating Consumption of Australian Seafood

Need

The CRC now has a wealth of current information about various aspects of Australians seafood consumption. The issue now is how to get this information out to the various stakeholders in the Seafood industry in such a format that companies can use the results in a very practical way to improve their returns and ensure their continued sustainability.

This education module has been designed to be practical, flexible and widely disseminated and so fulfil needs in several ways as follows:

• The module has been designed based on a transformational learning model, that is, a model where participants are required to reflect on their current practices and behaviours and then based on information provided, plan operational changes to maximise firm benefits.

• The module is being designed for delivery in two formats, face-to-face and digitally/online to maximise the potential audience reached. The online materials will provide access for those who cannot attend face-to-face sessions, as well as providing an ongoing resource for those who do attend face-to-face.

• The face-to-face component will be delivered in a mix of capital cities and regional locations to maximise exposure to where industry is actually located. This multimodal approach is designed to ensure the widest possible dissemination of results as well as providing face-to-face participants with a resource than can use within their own organisations.

Summary

The Seafood CRC now 'owns' the most up-to-date and extensive research data on how and why consumers purchase and consume seafood, gathered through a variety of projects including Repositioning Australian Farmed Barramundi, the Omnibus Surveys and the Retail Transformation project to name a few. The challenge was to communicate this knowledge, and more importantly to help firms to apply this knowledge to achieve improved returns.

This project was an Education and Training project with a key purpose being the dissemination of consumer research findings from other CRC projects. This project allowed for wider dissemination by not only relying on face-to-face delivery but also developing an online resources equivalent.

Seafood CRC: broodstock and genetic management of Southern Bluefin Tuna and Yellowtail Kingfish

Need

SBT:
There is a need to better identify the relationship between hormonal treatment and spawning performance as this will determine the hormonal manipulation strategy. There is also a need to better
understand factors associated with broodstock mortality, as currently 30% of the broodstock die every year and thus need to be replaced.

We need to develop methods of ensuring that all females participate in spawning every year and how to extend the spawning cycle to have eggs for four months of the year.

There is a need to advance the initiation of spawning to October (from the current norm of February) so that the fingerlings are ready to be transferred to sea cages sufficiently early in the calendar year for optimal seawater temperatures.
SBT broodstock reach spawning age at about 12 years of age. There is therefore a need to examine alternative technologies and approaches to obtain tuna seed from younger fish.

YTK:
This genetic management and selection project is needed to maintain a commercial advantage in a highly competitive market and as a management tool to prevent inbreeding.

It is difficult to source wild YTK broodstock, and the current stock are getting older and larger. There is a need to source new broodstock, and it will be advantageous to use selected F1, provided they can be genetically managed.

Objectives

1. Extend the spawning season of captive SBT from 2 months to 4 months
2. Bring forward the spawning season of SBT to achieve initiation of spawning in September/ October rather than the current February/April.
3. Monitor spawning dynamics of individual SBT broodstock
4. Develop a tool for sexing of SBT broodstock to ensure sufficient number of females are available
5. Maximise the number of SBT females that participate in the spawning and monitor egg quality in relation to hormonal spawning induction.
6. Aim to obtain natural spawning in SBT (i.e without the use of hormonal implants)
7. Investigate alternative spawning induction protocols with less physical impact on the treated fish
8. Determine the suitability of YTK as a surrogate for SBT and explore alternatives if needed
9. To develop a YTK genetic management and genetic breeding program for CST to control and minimise inbreeding (e.g. there will be no inbreeding depression for the commercially produced fish during the life of the project or in perpetuity)
10. To maximize the speed of commercial return by culling poor performing broodstock or by identifying preferred broodstock and using existing and new F1 stock

Seafood CRC: ACA market intelligence study tour to Beijing, China - combination industry bursary, research travel grant and student internship

Need

China is a significant market for ACA members and one where significant investment is already directed. China is a rapidly growing and rapidly changing market providing many challenges to ACA members wishing to develop sustainable business relationships as traditional supply chains to China are changing providing opportunities for Australian abalone product to enter Beijing direct being positioned as a premium quality product.

Consequently there is a need to develop both a research capacity and an industry skill base to enable the rapidly emerging opportunities for ACA exports to China. This project proposes a China research field trip involving 5 research students, 1 industry representative, 1 research internship student who is already working collaboratively with ACA focusing on a specific market sector for ACA in Beijing and the research Leader Dr Joanne Freeman. The market research field trip will be complemented by a formal education framework to enable both a commercial and academic perspective to be taken. The team as a whole whould gain a greater awareness of the role and significance of the Chinese seafood industry and how this awareness relates to opportunities for ACA members.

The market research field trip will provide industry participants and research students with the ability to compare and contrast markets (Australia and China) and to prepare actionable interpretive reports based on research findings. Furthermore, industry and students will attain an appreciation of a foreign culture as well as an awareness of cross cultural influences on business relevant to the Australian seafood industry.

This project also provides the opportunity for students to link with industry as a way of creating more "industry-ready" graduates.

Objectives

1. To develop robust actionable China market intelligence reports for ACA members

SCRC: PhD: Collaborative competition: Understanding the characteristics, drivers, constraints and advantages of collaboration within the Australian wild-caught abalone industry (Student: Ben Manning)

Need

The Chinese market provides significant opportunities for Australian live abalone exporters resulting from the massive growth of an affluent middle class, seafood consumption, food service trade, and seafood retail trade that appears under-served. These factors, coupled with abalone’s prestige status and the dominance of Australian product in the premium live market, indicate promise of a sustainable future. Despite Australia’s dominance in the market, there appears to be very little control over the market or price. Fluctuations in supply, quality and pricing inconsistencies are pronounced impediments to abalone’s success. These issues are further exacerbated by emerging competitive pressures from a fast expanding aquaculture sector in Asia, a lack of consumer and buyer product awareness, an insufficient promotional strategy, and a fragmented supply chain that lacks responsiveness in a dynamic market. Without a significant cooperative response to these challenges, the industry’s dominance and profitability are in danger. Short term promotional activities are unlikely to sustain the abalone industry into the long term, and an effective suite of strategies will be required. These strategies may be assisted through the formal development of an abalone industry cluster.
