A Roe’s Abalone (Haliotis roei) fishery in Western Australia (Area 8) suffered catastrophic mortality (99.9%) due to an anomalous environmental event in the summer of 2011. During this extreme marine heatwave there was a sustained period of elevated sea surface temperatures that rose to lethal levels for this species and effectively wiped out an entire stock at its northern distribution. Natural recovery within the foreseeable future was considered unlikely, thus providing a unique opportunity to test fishery restoration strategies for abalone. Over the course of this assisted recovery program (5.5 years) no natural recovery was observed in the region most affected by the mortality event.
