Aquafin CRC - Atlantic Salmon Aquaculture Subprogram: development of selective enrichment culture-polymerase chain reaction (SEC-PCR) for the detection of bacterial pathogens in covertly infected farmed salmonid fish

Bacterial disease is a major cause of stock loss in aquaculture. The severity of infection may range from acute to chronic through to benign. This latter condition, termed covert infection, is insidious, as fish may appear to be outwardly healthy but during periods of stress, these carriers may...

Seafood CRC: quantifying physiological and behavioural responses of cultured abalone to stress events

It is desirable for any primary producer to understand the health and welfare of their stock. This will ultimately enable optimal production and return on investment. The challenge in any aquaculture system is ‘observing’ the physiological and behavioural responses associated with environment,...

Vulnerability of the endangered Maugean Skate population to degraded environmental conditions in Macquarie Harbour

Maugean Skate (Zearaja maugeana) are only known from two isolated estuarine systems located on the west coast of Tasmania, representing one of most restricted distributions of any elasmobranch. There is, however, uncertainty about the continued persistence of the species in one of these estuaries...

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.
