Better Methods
Jul 2020 to Jun 2027
Status: In progress
Type: miShell supporting data collection
Aim:
To research and develop optimised methods to reduce mortality of Pacific oysters (Crassostrea gigas) from spat to end-consumer by identifying critical factors affecting survivability and implementing evidence-based interventions across production.
Determinants of Live Oyster Dispatch Mortality
Blue Farm Intelligence
2020.P3
Better Methods
Jun 2026 to Jun 2027
Status: In progress
Type: miShell supporting data collection
Aim:
To identify and understand the causes of live oyster dispatch failure from farm post-harvest to market. Failure is defined as oysters that arrive dead, moribund or unfit for sale or consumption. This issue represents a significant and widespread challenge within the aquaculture industry, resulting in considerable economic loss for growers.

PIA (formerly Kangaroo Island Shellfish) contributed to the Native Reef Restoration Project to construct 20 small, native flat oyster (Ostrea angasi) shellfish reefs close to Kingscote and American River to restore the health and function of these important shellfish and fish habitats. The new reefs provide habitat for premium recreational fishing species and contribute to a national initiative to restore shellfish reefs.
