Aquatic Animal Health Subprogram: development of management strategies for herpes-like virus infection of abalone

In January 2006, a previously unknown herpes‐like virus was identified as being the most likely cause of mass mortalities of abalone (Haliotis spp.) in a number of aquaculture farms in south‐west and central Victoria (Hardy‐Smith, 2006). The disease caused by the virus was named abalone viral...

Need

There is general agreement between government, environment groups, researchers and various industry groups that interactions between users of the marine environment and large marine animals are already a problem, and that interactions are likely to increase as populations of marine mammals recover and industries further develop. There is considerable public concern about such interactions, both nationally and internationally, as recent incidents have demonstrated. There is a growing interest from consumers in buying “clean and green” seafood, and in “ecotourism”. The problems have been well documented; however, there has been less focus on solutions. The most effective way to deal with the problems is to summarise existing information, identify the most pressing issues (including scientific, conservation and industry perspectives), and determine the status of efforts to resolve these issues. The next step is to select key issues to workshop. The workshop is needed to develop solutions and suggest policies which will prevent interactions from occurring in the first place if possible, and minimise harm. Where interactions cannot be prevented, innovative technologies should be identified that may minimise impact. The discussion paper will inform the workshop. Both the discussion paper and the workshop are expected to provide data for the development of appropriate government policies.

Objectives

1. To develop a discussion paper to summarise information about interactions between human activities and marine animals in temperate waters and to determine the key issues affecting large marine vertebrates. This will include an assessment of: available data such as coastal use and the timing of migration of large marine vertebrates
mortality figures
major problems
evaluation of previous attempts to resolve problems
current research both nationally and internationally.
2. To hold a workshop to scope effective methods, techniques and technologies to prevent or minimise problems with marine animals in the key areas identified in the discussion paper.

Investigations into the toxicology of pectenotoxin 2 seco acid and 7-epi pectenotoxin 2 seco acid to aid in a health risk assessment for the consumption of shellfish contaminated with these diarrhetic shellfish toxins in Australia

Project number: 2001-258
Project Status:
Completed
Budget expenditure: $20,000.00

Need

The need for the research lies in the fact that no guideline values exist for pectenotoxins in shellfish. To produce these guidelines toxicological data need to be produced and currently there is a lack of knowledge of the PTX metabolism and mechanisms of toxicity. There is currently no oral toxicology data on the PTX2- seco acids and thus their inpact on human health cannot be assessed. There have been no published works of their metabolism in mammals or humans, and their chronic effects on health are unknown. The clinical symptoms are non-specific to DSP poisoning and it is believed that cases of bacterial poisoning and DSP are mis-diagnosed due to lack of toxicological information.

The presence of pectenotoxins can impose significant economic burden on the shellfish industry. Clear toxicological data on pectenotoxins will be used to undertake a risk assessment of pectenotoxins to enable the shellfish industry and regulators to make informed decisions about the withdrawal of product from sale or closure of farms in the presence of pectenotoxins in shellfish.

Objectives

1. A comprehensive study has been undertaken in which the aims are to (i) develop a robust method for extraction, purification and quantification of pectenotoxins in shellfish, (ii) investigate the pathology caused by the pectenotoxins when ingested orally, (iii) investigate P450 metabolism of the purified PTXs with the use of microarray technology and (iv) conduct a health risk assessment for the consumption of seafood contaminated with pectenotoxins. This study will provide a greater understanding of the metabolism and mechanisms of toxicity for the PTXs and provide information useful in the clinical assessment of poisoned patients and also provide information to be used in the setting of guideline values for pectenotoxins in seafood.

Identification of stocks and migration routes of Torres Strait and Gulf of Carpentaria narrow barred Spanish Mackerel, Scomberomorus commerson

Of the eighteen species of Scomberomorus recognized by Collette and Russo (1979), the migratory behavior of only three species S. cavalla (king mackerel), S. maculatus (Spanish mackerel) and S. commerson (the narrow-barred Spanish mackerel) have been studied by tagging programmes. In these instances...

Species identification of Australia’s most significant octopus fishery – the Western Australian Common Octopus

This report summarises the scientific and consultation work undertaken to identify a new species name (Octopus djinda) and new common name (Western Rock Octopus) for the species that supports Australia’s largest octopus fishery, with 734 tonnes harvested in 2022. The species had been...
