A trial of non-lethal drum lines off WA's south-west coast will come to an end after catching just two white sharks in two years, with the state's chief scientist saying it did not reduce the risk of attack.
WA's chief scientist said it did not collect enough statistically useful dataAfter a spate of shark attacks in WA's South West, contractors rolled out 10 drum lines along an 11.5-kilometre stretch of beach in 2019 with the aim of catching, tagging, and moving white pointers offshore.
Of the 311 captures over two years, only two white sharks were caught, along with 266 other types of sharks, and 43 other "non-target" marine animals. In a report on the trial released this morning, it was revealed the two white sharks captured in the trial did remain offshore immediately after being relocated.
“The two-year smart drumline trial was conducted to the highest possible standards and served its purpose in generating data to enable the chief scientist to assess the effectiveness of the program in reducing the potential risk posed by white sharks," he said.
