Proposal for Seismic Testing off WA Coast Threatens Rock Lobster Industry

The rock lobster industry in Western Australia is sounding the alarm over a proposed seismic testing initiative off the state’s coastline, citing significant risks to the $240 million fishery. Pilot Energy is seeking to conduct seismic testing across a 946 square kilometre stretch of coast south of Dongara, aimed at identifying potential oil and gas reserves as well as carbon sequestration locations. This process involves the use of powerful air guns to create sound waves that penetrate and map beneath the ocean floor.

While seismic surveys are mandated by the energy company’s federal oil and gas exploration license, the specifics regarding the timing and methodology of the testing are yet to be determined. Concerns have been raised following a study conducted by the WA Government last year, which revealed that seismic testing left lobsters disoriented and confused.

Matt Taylor, CEO of the Western Rock Lobster Council, emphasised that research conducted on southern lobster species may not accurately reflect the impact on WA’s “less resilient” red crayfish. He highlighted the critical importance of the fishing grounds affected by the proposed testing, which support coastal towns and constitute a highly valuable area for the fishery.

The rock lobster industry in Western Australia is sounding the alarm over a proposed seismic testing initiative off the state’s coastline, citing significant risks to the $240 million fishery.

Taylor expressed concern over the established research findings, citing a significant reduction in lobster recapture rates, potentially attributed to the adverse effects of seismic activity on lobster behaviour and survival. Despite these concerns, Pilot Energy has shown reluctance to collaborate on research for the proposed survey.

In response, Pilot Energy spokesperson Matthew Smith affirmed the company’s commitment to addressing uncertainties and working with the Western Rock Lobster Council. While acknowledging the impact of seismic activity on marine life, Smith maintained that it was not directly lethal to lobsters but could modify their behaviour, potentially increasing their vulnerability to predation.

Smith emphasized the resilience of the Western Rock Lobster population and highlighted the proposed surveys’ limited impact on the species’ habitat. Additionally, Pilot Energy is pursuing plans for Australia’s first offshore carbon capture and storage (CCS) project, aiming to convert an offshore oil well at Cliff Head for CO2 storage.

However, concerns persist within the lobster industry regarding the risks associated with carbon storage beneath the seabed, including the potential for leaching into the water column and causing ocean acidification. Despite assurances from Pilot Energy, industry stakeholders remain vigilant, advocating for measures to mitigate the potential adverse impacts on marine ecosystems and the fishing industry.
