PROJECT: 2016/806

use of flow cytometry for surveillance of OSHV-1

WHY WAS THE RESEARCH UNDERTAKEN?

This research was undertaken to develop a method for OsHV-1 detection in the environment using data from in South Australia (seasonally) and Tasmania (monthly).

WHAT ARE THE MAJOR FINDINGS/OUTCOMES SO FAR?

  • Role of non-pacific oyster hosts.  There are many other filter feeding animals in the environment where outbreaks occur. Understanding their role is important in the disease dynamic.

  • Interest in fast tracking a rapid diagnostic method. Hatcheries and other operators will be able to get diagnostic information quickly in the event of mass mortalities.

  • Accelerating the capacity to grow alternative species. Growers are interested in having an alternative species they can grow in the absence of pacific oysters which are easy to farm.

  • Market diversity and farming approaches. The oyster industry is geographically compartmentalised and this has been an historical challenge until recently. The POMS outbreak has made many growers see that having gaps between the different growing areas is an advantage some of the time, yet this also brings certain business risks for individual operators and the importance of exploring ways to mitigate this that going forward.

PROJECT INVESTIGATORS

Marty received a PhD in parasitology from the Department of Molecular and Microbial Sciences at the University of Queensland. He has 10 years' experience in working with diseases and pests in aquatic systems. He has special interests in the properties of biological systems (including farms) that allow them to become infested by pests or infected by pathogens. Marty has significant experience in the use and registration of chemotherapeutants and disinfectants to manage diseases and pests, including designing and performing efficacy and safety studies, registration processes and ongoing monitoring of use. He has extensive experience in developing policy frameworks and supporting auditing and management capabilities for government. He is currently acting as Technical Executive to the Emergency Aquatic Animal Disease Response Agreement Working Group of Aquatic Animal Health Committee, an intergovernmental and industry group developing a framework within which formal agreements between aquatic industries and government could be developed for co-management and cost sharing in disease-related emergencies.
