Technology to deter shark attacks tested
Print Edition
Australian shark experts will test cutting-edge technology — including electrical barriers powered by wave energy — following an “unprecedented” series of attacks on swimmers.
The country has one of the world’s highest incidences of shark attacks and researchers met in Sydney yesterday at a conference organized in part to address community fears.
“What we’ve seen is pretty unprecedented,” New South Wales state Premier Mike Baird said of a string of attacks in eastern Australia which left one dead and seven injured.
A Japanese surfer died in February after his legs were torn off by a shark but there have been other serious attacks up and down the more than 2,000-kilometer-long NSW coast.
There have been 13 attacks in the state so far this year, compared to three in 2014.
“Ultimately, we’ve moved from a position in some parts of the coast where the coastline was joy... (to) fear, and we need to take that away,” Baird said, adding that his government hoped to test some of the recommended technologies during the upcoming summer.
Baird, who has ruled out culling sharks as an option, said he hoped experts would find ways to balance the need to protect humans against reducing the harm to marine life caught in barriers such as nets.
Deterrent technologies set to be reviewed include electrical barriers that can be powered by wave energy, as well as personal devices that surfers and swimmers can wear.
Detection methods include a smart drumline where sharks are removed from hooks before they die, and the “Clever Buoy”, which uses sonar technology to search for shark-sized objects.
