Summary

Spoilage of fresh fish products by the action of bacteria is one of the main causes of the short shelf-life of these products. A range of bacteria are responsible for this and are referred to collectively as "spoilage bacteria". Currently methods to detect both spoilage of the product and the presence of number of bacteria are time-consuming, for example requiring 24-hour incubation periods, or require specialised labour such as tasting panels. Near infra-red spectroscopy (NIR) is widely used in the food industry to monitor factors such as fat and moisture content in a range of foods. Although it has been used to distinguish different types of bacteria and, in a few cases, to quantify the number of bacteria in different materials, there is a lack of information on the ability of the method to quantify bacteria directly on food products. The aim of this project was to determine whether NIR had the potential to be used as a method to detect and predict microbial spoilage of fresh fish products.

NIR was easily able to distinguish between fresh Atlantic Salmon fillets and those stored for nine days at 4°C indicating that NIR can detect spoilage. Partial least squares regression prediction models for the number of total bacteria and the number of Enterobacteriaceae present were developed. These models used the NIR spectra collected when the fish was fresh to predict the number of bacteria that would be present nine days later. There are many factors (protein and fat content of the salmon itself for example) that contribute to the differences in the NIR spectra that are unrelated to the numbers of bacteria. Hence for any model to be useful it needs to include as many of these variables as possible. In conclusion, the results of this project show that NIR has potential to be a useful method for detecting and predicting bacterial levels on fish but much more work is required to develop a suitably robust model.

A range of bacteria are responsible for this and are referred to collectively as "spoilage bacteria". Currently methods to detect both spoilage of the product and the presence of number of bacteria are time-consuming, for example requiring 24-hour incubation periods, or require specialised labour such as tasting panels. Near infra-red spectroscopy (NIR) is widely used in the food industry to monitor factors such as fat and moisture content in a range of foods. Although it has been used to distinguish different types of bacteria and, in a few cases, to quantify the number of bacteria in different materials, there is a lack of information on the ability of the method to quantify bacteria directly on food products. The aim of this project was to determine whether NIR had the potential to be used as a method to detect and predict microbial spoilage of fresh fish products.

NIR was easily able to distinguish between fresh Atlantic Salmon fillets and those stored for nine days at 4°C indicating that NIR can detect spoilage. Partial least squares regression prediction models for the number of total bacteria and the number of Enterobacteriaceae present were developed. These models used the NIR spectra collected when the fish was fresh to predict the number of bacteria that would be present nine days later. There are many factors (protein and fat content of the salmon itself for example) that contribute to the differences in the NIR spectra that are unrelated to the numbers of bacteria. Hence for any model to be useful it needs to include as many of these variables as possible. In conclusion, the results of this project show that NIR has potential to be a useful method for detecting and predicting bacterial levels on fish but much more work is required to develop a suitably robust model.

Need

There currently is concern in SRL fisheries about the status of inshore stocks. Catch has declined in a number of areas, despite improvements in catch rates. For example, in Northeastern Tasmania, catch is at record lows, yet CPUE has failed to climb. Inshore stocks on western Tasmania are now receiving historically high levels of effort, due in part to change in shot rotation practices. Further, it is unclear whether the extra effort in these practices is adequately recorded in estimates of CPUE. There has been a recent increase in potting effort, commonly referred to as double night fishing, whereby fishers set and haul their pots twice a night, compared to the standard practice of emptying pots once at dusk and/or once during the day. Currently we have no data on the composition of the catch in double night shots, and what proportion of captured lobsters are handled and released, and what consequence this handling has on production from the fishery.

Summary

The specific aim of this thesis was to assess the effectiveness of individual transferable quota (ITQ) systems of management in meeting economic, ecological and social objective(s) through quantitatively analysing changing fishing practices and behaviour of fishers in the Tasmanian Southern Rocklobster (TSRL) fishery to inform management decision-making. Understanding how fishers behave and make decisions is critical in determining how best to manage fisheries. If the response of fishers to management measures can be predicted, unexpected and undesirable outcomes can be avoided.

ITQ management has been introduced in many international fisheries, with the purpose of accounting for human behaviour, as it theoretically generates behavioural incentives that are aligned with management objectives (e.g. reducing fishing costs). The ability of ITQ systems to meet continuing economic, ecological and social objectives therefore is centred on ensuring fisher behavioural incentives remain aligned with those objectives.

Need

Australian marine finfish farming has a target to increase production to 100,000 t by 2015 (Hone, 2008). In order to achieve this ambitious target considerable growth in the quantity and quality of hatchery produced fry is vital. This project adds critical mass to the highly skilled and specialised area of larval rearing research which will under pin industry growth.

Relevance to industry priorities and Seafood CRC milestones

Developing a sustainable, aquaculture-based supply of SBT juveniles is critical for the growth of the SBT industry in Australia. By increasing our knowledge of SBT and YTK biology, informed modifications to production systems will increase larval survival, addressing four specific outputs of the Finfish - Aquaculture Production Innovation theme including; Strategy 2: 1)Reliable production of SBT juveniles, and 2) Reliable, cost-effective production of high quality juveniles of YTK & other key species, and Strategy 3: 1) Established production techniques for propagated SBT, and 2) Improved feeds and feed management for marine fish during hatchery, nursery and grow-out stages (including during sub-optimal temperatures conditions). The CRC Milestones contributed to are 1.1.2 and 1.1.3 Key researchable constraints (in SBT and YTK larval culture) identified, characterised and successfully addressed.

Need

There are several reasons that targeted research on the variable cost of fishing is warranted as part of the bioeconomic activities of the theme. First, some fisheries regulations have evolved over long periods with lower fishing costs, a revision of these could increase the profitability of the fishery and may be necessary to ensure economic viability into the future. Secondly, fuel is one of the largest variable cost factors in most fisheries and has proven to be highly volatile in price over the last few years; extensive evidence suggests that fuel prices will continue to rise at rates significantly faster than most other costs. Third, the economic flows from fuel consumption tend to provide a lower contribution to GDP than other variable costs such as labour (due to the export nature of the cost); consequently disproportionate increases in fuel prices may result in a lower fishery contribution to GDP.

Need

Yellowtail Kingfish culture is a rapidly expanding industry in Australia, particularly in rural South Australia, where it is driving the increase in the ‘other’ category of aquaculture production from ~1100 tonnes valued at ~$9 million in 2002-03 to 2000 tonnes and $17 million in 2004-05 (ABARE, 2006). Regarding future production, CST alone are projecting an increase in annual production towards 8,000 T by 2015.

CST is the largest producer of Yellowtail Kingfish in Australia having produced over 1.25 M juveniles in 2007. The company operates two Yellowtail Kingfish hatcheries at Arno Bay and Port Augusta. The production of quality larvae from hatcheries underpins the production of farmed fish and low survival and high levels of malformations significantly increase costs.

Survival of Yellowtail Kingfish juveniles in Australian marine hatcheries is very low in comparison to many other marine species such as sea bass and bream produced in larger more mature industries, for example in Europe. Of particular note, several skeletal malformations have been reported in Australia and New Zealand, although few are well documented (Yellowtail Kingfish, Cobcroft et al., 2004).

There is also high variability in hatchery survival rates and the rate and severity of deformities among production runs and commercial hatcheries.

By way of illustration, the direct benefit to Clean Seas Tuna Ltd. of reducing malformations in Yellowtail Kingfish is estimated to be $1 million p.a. In this example a reduction in malformations from 40% to 20% (on 2.0 M juveniles before quality grading) could produce a further 400,000 good quality juveniles @ $2.50 (market value) = $1,000,000.

SCRC: Could harvests from abalone stocks be increased through better management of the size limit / quota interaction?

Project number: 2009-746

Need

This project addresses an issue which has been debated for some time in the Tasmanian abalone fishery and is discussed at most industry and management meetings. It is an issue that affects the size of the harvest, the price of product and the productivity of the stock. Thus there is a need to resolve this management debate and there is also a need to explore these ideas for higher production.

The project will be of greatest value for the regions of the state where growth information is limited as production is low (to put this in context, this component of the Tasmanian fishery accounts for around 1600 t of production, which is more than total production in any other state). Management issues in these locations are often hard to resolve because of lack of biological information. This project may allow management to proceed with a second-tier level of data derived from shell condition, which is far more readily obtained than tag-recapture data.

The project also addresses the need for information on density dependent growth in abalone - put simply, can production be increased by "thinning out" the stock. This is a fundamental question that is of interest for abalone stocks around Tasmania and also interstate.

Summary

Dr Jennifer Cobcroft and Assoc Prof Stephen Battaglene were invited to visit the aquaculture research laboratories of the University of Patras, Greece and collaborating research and commercial marine fish hatcheries in Greece (1-4 Sept 09). The visit enabled the development of an existing relationship with Assoc Prof Giorgos Koumoundouros, international expert in malformations in marine fish and helped to build research linkages between Australia, Greece and the broader European hatchery research community.

The laboratory and hatchery visits in Greece coincided with Larvi 09, 5th Fish and Shellfish Larviculture Symposium, the premier international event specialising in larval rearing research, the FineFish Final Workshop and a LARVANET workshop. In Greece, Assoc Prof Koumoundouros hosted a visit to the Laboratory of Zoology, University of Patras, where he demonstrated methods used by his team for assessment of fish samples for skeletal malformations and body shape. The methods used have direct applicability in the rapid processing and thorough classification of fish samples for quality assessment in Australian hatcheries.

Summary

The purpose of this travel grant was to conduct collaborative research to:

  • Investigate gene expression in early amoebic gill disease (AGD), including gene expression in different cell types to investigate AGD pathogenesis using metabonomics and assess further applications of metabonomics to fish health research
  • Compare Neoparamoeba perurans strains in Scotland and Tasmania
  • Develop collaborations with various UK academic staff from multiple institutions around the UK such as Centre for Environment Fisheries and Aquaculture Science, Stirling University, the University of Edinburgh, and Imperial College London.

This travel grant allowed the author to visit three salmon farms in Scotland – two Marine Harvest sites and one Scottish Salmon farm. A number of salmon were examined; however none of the farms had AGD outbreaks at the time of the visit. Collaboration was established with Marine Harvest to ensure availability of infected material from future AGD outbreaks.

The author visited Dr Jeremy Griffin at Cambridge University and Dr Jake Bundy at Imperial College London to discuss preliminary results for metabonomics from AGD infected salmon. These meetings were very fruitful, provided a lot of technical information and will most likely result in long term collaboration with Dr Jake Bundy. Preliminary results suggest that AGD infected fish can be differentiated from controls on the basis of their metabolite profile, at least in the later stages of the disease.

Future collaboration in the area of the use of immunostimulants in aquaculture was established with Dr Chris Gould and Dr Patrick Smith from Intervet Schering Plough and Prof Sandra Adams and Dr Kim Thompson from Stirling University. Dr Patrick Smith is following up similar testing of novel immunostimulants developed by University College Hospital Medical School in London. Collaboration was established with French researchers (Dr Philippe Sourd's group) investigating health of farmed Sea Bream and Sea Bass, AGD was diagnosed in some of their fish and this research was a joint presentation at EAFP conference and a publication.

Collaboration was established with Marine Harvest to ensure availability of infected material from future AGD outbreaks.

The author visited Dr Jeremy Griffin at Cambridge University and Dr Jake Bundy at Imperial College London to discuss preliminary results for metabonomics from AGD infected salmon. These meetings were very fruitful, provided a lot of technical information and will most likely result in long term collaboration with Dr Jake Bundy. Preliminary results suggest that AGD infected fish can be differentiated from controls on the basis of their metabolite profile, at least in the later stages of the disease.

Future collaboration in the area of the use of immunostimulants in aquaculture was established with Dr Chris Gould and Dr Patrick Smith from Intervet Schering Plough and Prof Sandra Adams and Dr Kim Thompson from Stirling University. Dr Patrick Smith is following up similar testing of novel immunostimulants developed by University College Hospital Medical School in London. Collaboration was established with French researchers (Dr Philippe Sourd's group) investigating health of farmed Sea Bream and Sea Bass, AGD was diagnosed in some of their fish and this research was a joint presentation at EAFP conference and a publication.

Preliminary results suggest that AGD infected fish can be differentiated from controls on the basis of their metabolite profile, at least in the later stages of the disease.

Future collaboration in the area of the use of immunostimulants in aquaculture was established with Dr Chris Gould and Dr Patrick Smith from Intervet Schering Plough and Prof Sandra Adams and Dr Kim Thompson from Stirling University. Dr Patrick Smith is following up similar testing of novel immunostimulants developed by University College Hospital Medical School in London. Collaboration was established with French researchers (Dr Philippe Sourd's group) investigating health of farmed Sea Bream and Sea Bass, AGD was diagnosed in some of their fish and this research was a joint presentation at EAFP conference and a publication.
