Need

The proposed evaluation will be critical to providing feedback directly from consumers on how effective the implementation of the Plan has been. This data can then be triangulated with data from industry (both qualitative and quantitative) to gain a full picture of all aspects of implemenation of the Plan. Specifically, the evaluation will measure reach and awareness of the campaign as well as identifying which media were effective in gaining consumer attention, recall of specific promotional items (recipe cards, posters, banners, decals etc) and the impact of the campaign on both consumers attitudes and behaviour. Further, we will be able to use existing knowledge of consumers purchasing behaviour and attitudes towards prawns as a benchmark against which this new data can be compared.

Summary

The primary objective of this travel grant was for the student to receive training in analysing RNA-seq data, from experts in aquaculture bioinformatics, to enable him to analyse a transcriptome dataset for Yellowtail Kingfish. The analysis of RNA-seq data requires the use of specific software tools, access to a powerful computer server or server cluster, and in particular specialised knowledge.

By working with NOFIMA staff, the student had access to all of these, and allowed him to successfully constructed a full transcriptome using data from 30 Yellowtail Kingfish. He was able to identify over 800 genes involved in fatty acid metabolism, transport and deposition, as well as differential expression patterns for each of these genes.

Summary

While histology and its meaningful analysis are important skills to possess, most histological work conducted at the University of the Sunshine Coast heavily focuses on human histology, with some vertebrate histology, whereas knowledge about the analysis of oyster histology slides is lacking.

This grant allowed the student to visit the Elizabeth Macarthur Agricultural Institute (EMAI) in NSW to learn the skills needed to histologically analyse oyster tissue.

Need

The Sydney Rock Oyster (SRO) aquaculture industry is the largest and oldest aquaculture industry in NSW with annual revenue of approximately A$35 million (I&I NSW 2011). SRO breeding was initiated in 1990 through mass selection aiming to develop faster growing, winter mortality resistant lines (Nell et al. 2000). After five generations the average time to market size reduced by more than 12 months (Nell and Perkins 2005) and disease resistant lines were available. In 2004, the first progeny from 5th generation fast growing lines were distributed to oyster farmers in NSW. In comparison to wild-caught oysters, these stocks demonstrated clear differences in reproductive behaviour, which affected marketability in various estuaries throughout NSW (O’Connor and Dove 2011). While industry demand for selectively bred SRO remains strong (2011/2012 spat sales will exceed 20,000,000 and will form the basis of more than 20% of total production), these changes pose both challenges and opportunities for the entire SRO production cycle from the hatchery, where oysters in “ripe” reproductive condition are required for spawning, through to market where reproductive condition is a major determinant in “saleability”.

With the progression of the SRO breeding program from 3 “base” mass selected lines to 120 pair-mated families, investigation into the biology behind the altered condition index of selectively bred oysters is of great importance. Initially, there is a fundamental need for reproductive concurrency among lines to allow breeding. Secondly, genetic variability in reproductive condition offers the opportunity to manage marketability through the selection of lines whose characteristics suit market requirements.

SCRC: Development of germ cell transplantation technology for the Australian aquaculture industry

Need

Currently SBT is being bred in an expensive on-shore facility at Arno Bay, where a single tank holds a limited number of broodstock, which spawn for a limited period of time. In order to expand on the
production of SBT seed, additional facilities/tanks at the costs of millions of dollars will be required and
sourcing additional 12 year old broodstock. Therefore there is a need to look at alternative approaches
for SBT broodstock management. This proposal explores the application of a highly innovative
approach - that is the use of fish surrogates to produce SBT. By identifying the right surrogate for SBT
and developing the specific know-how with respect to optimal germ cell management, SBT seed could
be produced in a fast maturing small host. This would completely overcome the need for large,
expensive broodstock facilities and long term holding of broodstock, while ensuring a continuous
supply of SBT seed, which is much needed for larval rearing R&D and commercialization. This
application relates to the overall investment in closing of the life-cycle of SBT.

Summary

The project was designed to explore the application of surrogate technology as an alternative broodstock system for the Southern Bluefin Tuna (SBT). Surrogate technology, also known as germ cell transplantation, uses germ cells from a donor species, in this case SBT, and transplants them into a host species, the surrogate. The germ cells can migrate and form part of the host’s gonad, resulting in the production of the donor sperm and egg by the host gonad.

We have explored the suitability of the Yellowtail Kingfish (YTK) as a surrogate for SBT. Over 12,000 YTK larvae were injected with SBT germ cells, and 3-4 weeks after transplantation we could observe the migration and colonisation of the SBT cells (which are labelled with red florescence dye for ease of detection) to the YTK genital ridge, confirming SBT cells responded to YTK migration cues. Transplanted larvae were raised and samples assessed a few months later, however so far we could not detect SBT cells in the maturing YTK, indicating that whilst SBT germ cells respond to the YTK migration cues we cannot confirm proliferation of the germ cells in the YTK host at this stage. About 100 YTK approaching one year of age are maintained at CST and will need to be examined for the presence of SBT sperm or eggs once they reach sexual maturity.

Need

In 2008-09, the aquaculture oyster industry contributed about 92 million Australian dollars (~ 14,000 t) to the Australian economy. To maintain and potentially increase this contribution of the oyster industry to the Australian economy, knowledge needs to be gained regarding the effects of stressors such as disease (e.g. QX or winter mortality), pH (acid sulfate soil leachate), temperature, salinity and contamination caused by oil spills on the animals, as these stressors weaken the oysters, potentially resulting in an increase in their mortality or decrease in their quality. This in turn is directly linked with the economic value of the oysters and the profitability of the industry.

This project is relevant to the "Breeding for profit" Seafood CRC business plan and links with the Seafood CRC research program 1, Genetics theme, application of emerging technologies. Moreover, it is also relevant in regards to the Oyster Consortium goals, which aim to 1) improve breeding strategies to continue lifting the quality of oysters and to 2) increase our understanding of oyster health and its links with the environment.

The project aligns with the NSW Aquaculture Research Advisory Committee goals to:
1. maintain and improve the breeding program to produce oysters that are faster growing, disease resistant and in better condition for marketing.
2. increase the understanding of the QX and winter mortality disease, as well as other parasites and pests.
3. investigate the impacts of the environment on oyster farming.
4. improve the understanding of potential impacts of climate change on oyster farming and to develop strategies to deal with such changes.

Summary

The small business sector is a foundational element of national economic performance and the provision of employment to millions of workers globally. There is considerable research literature regarding strategy and strategic planning in the context of large, small and micro businesses. However, there is a paucity of research relating to Australian commercial fishing micro-businesses. This study is focussed on exploring the use of strategy and strategic planning at the micro-business level within the Australian commercial fishing industry.

Need

In line with the pervasiveness of gut related illnesses, a recent study by the Tasmanian Institute of Agricultural Research (TIAR) on microbial communities of the hindgut of salmonid fish has shown that these microbial ecosystems are heavily influenced by the local aquatic environment and to some extent diet formulations (Bowman et al 2006). According to this report the intensive feed regime combined with local environmental conditions can lead to overgrowth of certain bacterial species within the gut. The higher number of bacteria in fish hindgut during summer time compared to autumn suggests that the temperature may be instrumental in promoting an overgrowth of pathogenic species. The activity of these bacteria may then lead to a suboptimal feeding and health of the salmon. Clinically this is associated with loss of appetite and reduction in growth rate and a diarrhoeal-like faecal excretion is observed (Bowman et al 2006).

Little is known about the exact pathogenic mechanisms used by these bacteria to cause disease and there is a real need to alleviate pressure on the aquaculture industry from diseases caused by these bacterial species. This project as shown in the objectives is to be run parallel to another project recently accepted by the seafood CRC in providing information on these pathogenic bacteria to be used for testing the efficacy of any isolated probiotics.
