The State Government is supporting research to monitor whether cage-diving operations pose any threat to Australia’s protected white sharks.
Fisheries Minister Michael O’Brien said scientists and cage-diving operators are collaborating in a world-first project.
The research, partly funded by the Wildlife Conservation Fund Grants from the Government of South Australia, the Nature Foundation of South Australia, and the Neiser Foundation, is led by SARDI and Flinders University shark ecologist, Dr Charlie Huveneers.
“It will provide important information to help the State Government manage the growing industry, which relies on the survival of the threatened species,” Mr O’Brien said.
“Its outcomes will also help inform similar cage diving operations around the world in places such as New Zealand, South Africa and Mexico.”
Mr O’Brien said Dr Huveneers’ team and cage operators are working together to tag 10 white sharks which inhabit the area around Australia’s main cage-diving operations off the remote Neptune Islands, 75km from Port Lincoln.
Berleying is only allowed if a ministerial exemption is granted under Section 115 of the Fisheries Management Act.
“At this stage, eight white sharks between 3 to 4.5 m have been tagged since December,” Mr O’Brien said.
“The white shark cage-diving industry at the Neptune Islands attracts a large amount of tourism to South Australia and Port Lincoln.
“However, the impacts of such activities are still poorly understood, and there is a need to investigate how berleying might affect white shark behaviour and movements.
“It is important to ensure that this industry is sustainable and that it does not negatively impact on the white shark population frequenting the Neptune Islands.”
Mr O’Brien said the research would provide crucial data to help the Government assess if the current level of berleying around the Neptune Islands is impacting on shark behaviour.
