Need

Aquaculture is expanding not only overseas but also in Australia and this has attracted a cadre of young scientists with little experience in aquatic animal health. Although not all “aquatic” techniques are unique there are some aspects that are specific to aquatic technical skills and procedures. In addition, some of these inexperienced scientists/technologists feel that they are on their own and are even intimidated to request assistance. In some instances they don’t know where to go or whom to ask for input or direction.
The “aquatic animal heath” discipline involves a relatively small number of specialists that do not get the opportunity to convene at meetings/workshops/ conferences as often as those involved in the terrestrial animal health sphere.
The forum activities will include;
1) the planning and hosting of annual training workshop

2) further development of the established email discussion group

The forum would be open to all aquatic animal health specialists and industry personnel eg. fish farm staff who will be encouraged to register as a member of the forum. The forum will include annual workshops for participants with a variety of skills and levels of experience and who are resident at government laboratories, universities and colleges. This will build on the previous skills workshops that have been conducted in 2010 and 2011, which has assisted in the development of functional networks for the exchange of information and enhancement of the skills of the aquatic animal health service providers and on farm staff.
In addition to developing a valuable national resource - a repository of technical knowledge – the forum provides mentoring to the new generation of laboratory technicians, students and staff at diagnostic laboratories, teaching institutions and aquaculture enterprises.

Objectives

1. To further develop the email discussion group for the Aquatic animal health technical forum
2. To ensure the continuation of technical information transfer between forum members
3. To organise annual workshops at various institutes that provide specific aquatic animal health services.
4. To open the forum to international participation and thus enhancing the knowledge base of the forum members, for example exotic diseases.
5. To canvass State Departments for potential funding contributions to enable the continuation of the forum beyond 2015.

Need

This project has been developed to address the following needs:

• Non- scientific people in the seafood industry need to have concise and clear guidance on how to assess shelf-life and quality of new products and advice on selection of packaging options
• Foodborne pathogens currently considered to be of low risk in seafood products may become a high risk in new product types, these need to be clearly identified within appropriate guidelines so that industry can ensure product safety.
• Current CRC projects have focused on the development of new product types and assessment of product shelf-life. This project will utilise knowledge gained in these projects and increase the uptake of current CRC outputs
• There is a need to reduce costs of unnecessary tests for new products

Summary

This project aimed to assist the seafood industry with sound practical advice on the assessments of food safety and quality aspects of new packaged seafood products in a concise and clear format.

Seafood processing and packaging techniques such as modified atmosphere packaging and vacuum packaging have been utilised by the seafood industry to extend product shelf-life, assist in meeting the demand for quality and safe products by consumers and create new market access. However, these techniques can support the growth of certain pathogens that were previously considered to be of low risk. Furthermore, feedback received during discussions with national and local seafood processors suggest the seafood industry has difficulties with assessing food safety and quality attributes of newly developed products.

Summary

This Guide aims to assist seafood processors who are developing new packaged seafood products to understand:

  • potential food safety risks
  • regulatory requirements
  • processing and packaging techniques
  • shelf-life assessment programs

It is important that businesses developing seafood products consult with their relevant competent authority to determine specific testing requirements and sampling regimes for their products.

SCRC: Seafood CRC Visiting Expert and Master Classes - Dr Paw Dalgaard - SSSP and related food safety and quality software

Project number: 2010-765
Project Status:

Need

The proposal is primarily concerned with improving skills and productivity of the Australian seafood processing and retailing industry as a whole. The Food Safety Centre is, essentially, merely the proponent.

The Seafood CRC has identified chilled, pre-packaged, seafood presentations as a way of increasing industry profitability. Such products, by virtue of the greater handling and longer shelf-life, are potentially at higher risk of contamination with unacceptable levels of microbial pathogens requiring higher skills and technology for management of the risk. Coupled with rapid diagnostics technologies, predictive models and quantitative knowledge of the microbial ecology of seafoods form a strategic platform for expansion into new markets based on these value-added products. Such products are already well established in Europe.

Dr. Dalgaard is an international expert in seafood microbiology, being a long-term member of the National Food Institute (DTU Food) (formerly: Danish Institute for Fisheries Research). The Food Safety Centre has collaborated with Dr. Dalgaard on various predictive microbiology projects over the last 15 – 20 years but few have specifically involved seafood applications due to sources of funding within Australia. With our involvement in the Seafood CRC we consider that useful synergies will arise, particularly in the areas of histamine contamination of seafoods, and Listeria monocytogenes control, in long-shelf life, mildly-preserved fish products – a market that the Australian industry has to develop to increase profitability. This Master Class series will support the > $2million investment of the Australian seafood industry (through the CRC) into new retail and foodservice presentations with longer shelf life and employing novel processing/preservation technologies. It will provide a means to develop new products and processes, but with far less reliance on costly and time consuming challenge trials.

Summary

Dr. Paw Dalgaard of the Danish Technical University is internationally recognised for his work on microbial quality, spoilage and safety of fish. His research studies are made accessible to industry through internet software that can be used to predict the growth of bacteria of interest on seafood from measurements of temperature, pH. salt-in-water, organic acids and gaseous atmosphere in the case of modified atmosphere-packed seafood. Those computer models can be accessed, free-of-charge, and are known as the Seafood Spoilage and Safety Predictor (‘SSSP’; http://sssp.dtuaqua.dk/). They are widely used in Europe and internationally.

Dr. Dalgaard’s visit was an opportunity to deliver a number of master classes in Australia, and to showcase the newly developed Australian Oyster Refrigeration Index (an analogous tool to assess microbiological safety and quality of oysters) developed in Australia with Seafood CRC funding.

The visit occurred from 29 May to 10 June 2011, and involved visits and discussions with staff from various seafood business, research and regulatory organisations. Furthermore, Dr Dalgaard presented two master classes on predictive microbiology for seafood and one symposium on management of Listeria monocytogenes in ready to eat foods.

Overall, approximately 80 stakeholders in the Australian seafood industry interacted with Dr. Dalgaard, and a further 100 food safety managers in government, retail, consultants etc. attended lectures by Dr. Dalgaard at the Listeria management symposium.

Seafood CRC: genetic technologies to support a transformation to profitability and competitiveness in F. merguiensis and P. monodon

Need

There is a need to meet the CRC’s desired $240 million gain in seafood value through innovative technologies as scheduled in the CRC program 1. This proposal will contribute up to 47% of this CRC goal, as explained in the “background” section.

This application also meets the need to respond to the FRDC’s challenge 3 (response to demand, profitability) and FRDC priority “develop innovative processes for value-adding through
development” (genetic improvement will return greater profit per kg, or increase kgs for same infrastructure). Should the “Seafarm” transformational model be adopted by others, this will directly support the achievement of FRDC’s key performance indicators “at least two companies accessing new markets”, and “at least two entities utilizing improved stock from selective breeding”.

This application supports the stated and written need from the APFA, as a major stakeholder, to achieve a method to apply its R&D levy for the whole of the industry, for both P. monodon and F. merguiensis. The application makes the case that as a transformational model for profitability through innovative technologies this project delivers industry wide outcomes

Objectives

1. Understand if past and existing breeding practices led to significant inbreeding (more than 2% per generation) and, if substantial inbreeding has occurred and will continue to occur, develop options to track family pedigrees and so more effectively limit inbreeding
2. Estimate genetic heritabilities and correlations for commercially important traits. This information will be available for companies to develop efficient breeding programs
3. Determine if functional markers for a range of commercial traits are commercially feasible. If so, these makers will be available for companies to integrate into their breeding programs through a selection index

Summary

Seafarm, at Cardwell, for most of the last 20 years, has been Australia’s largest prawn farm and the major producer of Banana Prawns. This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

Need

The mass mortality events are very economically and ecologically damaging. Economic damage occurs acutely in the short-term due to the need to close the fishery during events and damage also occurs in the longer term owing to the removal of large numbers of fish during the event.

No model exists of the spatial propogation of a viral epidemic in an exploited fish population, we will derive such a model. This model will be aimed less at predicting the spread of a particular mass mortality event and more at the understanding of the dynamics of the event. Using the model we will be able to assess hypothesises concerning the factors which control the mass mortality and hence focus future study on the most sensitive processes. The model will also show the conditions under which these events may recur. We will also be able to assess the potential for management intervation to halt an ongoing epidemic or prevent further outbreaks. The model will also integrate all the aspects of the spread of the mass mortality events, showing linkages within the existing data and showing those areas for which adaquate data is lacking.

It should also be noted that damaging epidemics among wild caught and farmed marine fisheries are not infrequent and that modified versions of the model may have future applications to other fisheries.

Objectives

1. We will construct a 1-D SIR (Susceptible, Infected, Removed) model of the spread of the pilchard mass mortality events of 1995 and 1998/9
2. We will analyse the effect of different modes of local transmission on the mass mortality's dynamics.
3. We will produce a literature review of similar mass mortalities and the modelling approaches used to analyse them.
4. We will refine the SIR model to include different transmission process functions and data obtained by other pilchard mortality study projects, in particular the Fisheries WA lead study on viral transmission.
5. We will review the observations, including those obtained in concurrent studies, to provide the tightest possible constraints on the ranges of model parameters.
6. We will analyse the effects of fisheries management strategies on pathogen transmission, in particular we will test the viability of a 'fire break' policy.
7. We will construct a simple model of the recovery of the fishery to investigate the period required for the stocks to become vulnerable to renewed mortality.
8. We will develop a Graphical User Interface (GUI) to display the local and geographical spread of pathogens.
9. We will produce an initial report detailing the approaches used both by us and other modellers of epidemics.
10. We will produce a final report detailing the final form of the model produced and incorporating analysis of model structure, parameters and results.
11. We will present this work at a nationally significant scientific meeting in 2000.

Oysters Australia IPA: the use of FRNA bacteriophages for rapid re-opening of growing areas after sewage spills

Project number: 2015-037
Project Status:
Completed
Budget expenditure: $270,273.00

Need

Oyster growing areas with reticulated sewage and/or waste water treatment plants (WWTP) in the catchment are all potentially affected by closures caused by sewage spills and overflows. Standard risk management practice following such events is to instigate a 21 day closure resulting in lost production, market share, reputational damage, and potential recall costs. The number of growing area closures related to sewage spills and overflows in Australia is significant. In NSW, harvest areas were closed on 100 occasions due to sewage spills between July 2009 and June 2014, resulting in 2688 days of lost sales. The use of FRNA phage as potential indicators of human enteric viruses could lead to a 50% reduction in the number of days closed.
In Tas, there have been 75 harvest area closures of greater than 21 days relating to sewage spills over the past 5 years, resulting in at least 1575 days of lost sales. One three week closure in the Pittwater growing area is estimated to cost approx. $250-$400k combined sales, depending on the season. The cumulative impact of these spills has been estimated to reduce the value of businesses by a combined value of $12 million. Not all sewage incidents result in human enteric viral contamination of shellfish. Factors such as the level of illness in the community, treatment level of waste, size of the spill, hydrodynamics of the growing area, and local growing area conditions all influence the whether a spill results in significant contamination of oysters. FRNA phages have not been used routinely as indicators in shellfish in Australia to date. If FRNA phage levels show contamination is negligible, regulators may allow re-opening of growing areas as early as 10 days after the spill following results from testing on day 7, significantly decreasing the cost of spills to growers. FRNA phages are also showing potential as general indicators of human pathogenic risk.

Objectives

1. Establish baseline levels of FRNA bacteriophages in “at risk” Australian growing areas
2. Determine appropriate sampling plans for FRNA bacteriophages in shellfish following sewage incidents
3. Enable implementation of FRNA phage levels as a management tool for use following adverse sewage incidents in bivalve shellfish growing waters
4. Train laboratories to be competent in using appropriate testing methodologies for FRNA phages in shellfish

Summary

The South Australian Research and Development Institute (SARDI) Food Safety and Innovation (FSI) group with the support of the Fisheries Research and Development Corporation (FRDC), TasWater, Central Coast Council, Port Macquarie-Hastings Council, Shoalhaven Council, New South Wales Food Authority (NSWFA), New South Wales Shellfish Program, Oysters Australia and Tasmanian Shellfish Quality Assurance Program (TSQAP) undertook an investigation of the use of FRNA bacteriophages (phages) as indicators of viral contamination in shellfish after adverse sewage events. The human enteric viruses Norovirus (NoV) and Hepatitis A virus (HAV) are the most commonly reported foodborne viral pathogens associated with shellfish. The viruses are bioaccumulated by shellfish when sewage enters water in the growing areas. Oysters were sampled from ‘at-risk’ growing areas to establish background baseline phage levels from July 2016 to December 2017. Five adverse sewage events were also investigated during the same period. In addition, training in the laboratory techniques for phage enumeration was undertaken at the SARDI FSI laboratory in Adelaide for staff from laboratories in NSW and Tasmania.

Need

This application is in response to the priorities identified in the NSW FRAB's recent stakeholder priorities workshop (developing the professional credentials of the NSW Fishermen).

This pilot will assist the NSW SFM Pilot (CRC Project MB079) and SSA EOI (AS015), by ground-truthing the industry on-ground components of the Responsible Fishing Scheme within the NSW context, but will be designed and implemented to keep the national context as a future capability.

In addition, the application is in response to, and addresses the need of, the FRDC R&DE Priorities areas as follows; Program 1: Environment (Theme 4 - Ecologically sustainable development),Program 3: communities (Theme 10 - Resilient and supportive communities) Program 4: People development (Theme 12 - Workforce development) (Theme 13 - Innovation skills) and Program 5: Extension and adoption.

The project will also embrace previous industry development research outputs not extended to stakeholders including the ASIC Code of Conduct for a Responsible Seafood Industry and the Sydney Fish Market Seafood Handling Guidelines, as well as lifting the profile of the existence, contents and benefits of industry adopted codes of practice amongst NSW fishers.

Extension of the project outcomes will also have the potential to provide a mechanism for expressing industry’s values (both individual and as collectives) to communities and other stakeholders, by highlighting the environmental credentials of participating fishermen .

Objectives

1. Gain industry support for uptake of CoPs in NSW and industry training and accreditation
2. After feedback from industry, review and align current NSW Estuary fishery Code of Practice to FAO (international)and ASIC (national) codes -
3. Develop training materials for fishers focussing on fishing practices fishery regulations and environmental best practice aligned with the Seafood Training Package
4. Train NSW SeaNet Officer in Cert 4 Workplace Training and Assessment
5. Deliver training workshops to fishers as a pilot, assess and accredit against training package competencies
6. Acknowledge successful participants as "Master Fishermen"
7. Create interactive database of supporting information

Need

The CRC has a significant investment in abalone production from both aquaculture and wild catch sectors. This project will address two needs across this broad suite of projects.

The first is to engage with national and international industry members, researchers and managers, working on similar topics elsewhere in the world to avoid repetition of existing and future research, learn from their experiences, and to ensure that CRC research is cutting edge.
The second is to enhance the outcomes from these projects through engaging with and communicating to numerous national and international stakeholders.

The forum proposed here is a cost effective opportunity to address these needs for CRC projects on abalone for both production sectors. It will be held as part of the 8th International Abalone Symposium in Hobart in May 2012 so that research and participants from elsewhere can be part of the sessions.

The CRC Forum will run over at least a single day to encourage participation of industry at a conference that would otherwise be dominated by academics. Funding sought here is to subsidise industry attendance to increase participation.

The forum will be based on areas of CRC research activity:
1) Reseeding workshop
2) Marketing session
3) SnailBASE workshop
4) Aquaculture nutrition session

Summary

The main aim of this project was to engage with national and international industry members, researchers and managers, working on topics similar to CRC projects elsewhere in the world. The CRC Abalone Forum was run in Hobart in May 2012, in conjunction the 8th International Abalone Symposium in Hobart in May 2012 so that research and participants from elsewhere could be part of the sessions. The conference and thus the forum attracted a large number of registrants (261) from 19 countries.  The forum dealt with areas of special relevance to CRC projects and was effective in generating outputs from the CRC with many papers currently under review for publication in a refereed journal.  The forum also included sponsorship for industry registrations which contributed to the larger than usual participation of industry in this type of event (130 registrations).

The reseeding workshop was held to review and reinvigorate the concept of abalone enhancement. Enhancement operations were showcased from Japan, the USA and New Zealand. Presentations explored field methods of stock enhancement/reseeding and evaluating survival to help direct future efforts and maximise efficacy.

The CRC has substantial investment in marketing.  The forum assisted with this through the presentation of information on global production and markets. The intent was to develop a better-informed Australian research and industry community fully aware of the latest global trends.

A workshop was also held to progress the development of “SnailBASE” which involved participants from several countries.

Need

The Australian Abalone Growers’ Association met in September 2009 and identified their priority areas for research. Their two highest priorities were: 1. Identification of nutritional requirements for abalone at different life stages; and 2. Identification of nutritional requirements for abalone for different seasons. Thus, this is clearly an area requiring research and collaboration with abalone growers. Therefore this project will contribute directly towards two of the industry’s identified priorities through enhancing the information generated by 2010/736.

This project lies directly within the A and B of Seafood Theme outcomes. In particular, this project addresses outcomes 1 (Academic researchers with specialist skills and knowledge specific to the seafood industry continue to be available to provide research and technical capacity to the Australian seafood industry) and 2 (CRC industry participants have the necessary skills to implement CRC research results for the use in the aquaculture and wild harvest businesses).

Seafood CRC: controlling biofouling of pond aerators on marine prawn farms

SPECIES

Need

Biofouling of aeration equipment is a significant farm management issue and production cost for Australian marine prawn farms. Defouling aeration equipment has a high labour demand and once fouled the energy efficiency of paddle-wheels and other aerating equipment can be markedly reduced, leading to elevated electricity costs and shorter equipment life. The estimated cost of biofouling is a minimum of $1,000 per hectare per crop when considering the additional labour, maintenance and electricity costs that it creates. This cost figure however does not include the impact of aerator fouling on prawn production levels which potentially could be far greater. The industry uses up to 10x aerators per hectare and they consume 70-80% of total farm energy use. It is estimated that at the peak of the production season around 6,000 2hp aerators are in use in ponds across the prawn industry alone.

Ensuring appropriate and timely aerator defouling is conducted is a significant farm issue. Manual defouling is one of the least desired tasks on the farms as it is dirty, laborious and workers are susceptible to multiple skin cuts that are prone to infection. Consequently it can be difficult to maintain staff to undertake this task for any length of time.
There is no data available on the impact of biofouling on the aeration efficiency, for example the oxygen transfer rate, and this information is critical to maximising benefit from mitigation strategies from both a practical and economic stand point.

The relevant industry body, the APFA through the R&D Committee, has assessed prevention of aerator biofouling as a priority issue and has recommended that the project commence as close as possible to the start of the current production season.

The proposed project falls within the Seafood CRC Theme – ‘Aquaculture Innovation’ as the objective is to improve production efficiency.

Objectives

1. Review biofouling control options and select those with greatest potential for application on prawn farms.
2. Assess the impact of aerator biofouling on prawn farms.
3. Transfer methods for implementing aerator biofouling controls to the prawn farming industry.
4. Evaluate selected biofouling control options under commercial conditions.

Summary

Biofouling of aeration equipment is a significant farm management issue and production cost for Australian marine prawn farms. Defouling aeration equipment has a high labour demand and once fouled, the energy efficiency of paddle-wheels and other aerating equipment can be markedly reduced, leading to elevated electricity costs and shorter equipment life. The estimated cost of biofouling is a minimum of $1,000 per hectare per crop when considering the additional labour, maintenance and electricity costs that it creates.

The project was designed to assist the Australian prawn farming industry improve aeration efficiency through providing farms with new information pertinent to cost-efficient management of their aerator fleet. The project focussed on the impact of biofouling on aeration and measures to control its accumulation, though broader aspects of aeration were also considered.

On-farm monitoring of aerators determined a huge variation in aerator electrical performance within and among farms. Around 60% of the electrical use variability among paddlewheels is due to biofouling accumulation. This also means that around 40% of differences among paddlewheels is attributable to mechanical factors such as degree of wear and tear.

The overarching output from the research conducted under this project is an improved understanding and quantification of the problem of biofouling in the use of aerators in marine prawn ponds. Farms are under pressure to become increasingly efficient production systems and the information arising from this project will substantially contribute to the farm knowledge base drawn on to optimise strategies that reduce aerator fleet management costs.
