Objectives

1. To determine methods for the conditioning/husbandry of spat and juvenile oysters to obtain survival after exposure to OsHV-1 based on improved scientific understanding of exposure, pathogenesis, immunity, tolerance or latency

2. To confirm i) the consistency of seasonal patterns of POMS, ii) the periodicity of infection within season, iii) inter-estuary temperature variation, and iv) predict POMS seasonal behaviour.

3. To identify changes in OsHV-1 DNA sequence over time (2010-2016) to understand infection and disease patterns

4. To investigate the mechanisms of survival of Pacific oysters after exposure to OsHV-1, including assessment of exposure dose and using biosensors

5. To determine whether water treatments prevent OsHV-1 infection of spat or merely prevent mortality, and whether they can be applied for biosecurity of hatchery effluent

6. To describe an integrated disease control strategy based on complementary use of genetically resistant oysters (when available) and husbandry methods throughout the production cycle: hatchery-juvenile-growout to market

7. To build capacity in aquatic animal health for Australian industry through training a post graduate student
