Several critically important steps to achieving the central long-term aim of this project namely, cost-effective enhancement of abalone fisheries using hatchery produced seed stock, were achieved. The first was year-round controlled temperature conditioning and spawning of captive broodstock. This...

The primary goal of this research was to identify attributes of the seasonal biology of Blacklip Abalone (Haliotis rubra; hereafter referred to as Blacklip) that may be beneficial for optimising fishing strategies. The optimum months to harvest Blacklip to maximise yield were identified using a...
The project was able to successfully propagate a new P. olseni isolate from Queensland and successfully cultured the isolates from Spain, Japan, New Zealand, and South Australia as well as P. chesapeaki, which was used as a negative control. We were unable to culture the Western Australian (WA)...

Abalone viral ganglioneuritis (AVG) remains a significant threat to the economic viability and stability of the Abalone industry in south-eastern Australia. Consequently, there is an urgent need for strategic research aimed at determining the likely vulnerability of fisheries to future AVG outbreaks...
