The Western Australian government caught 172 sharks, and killed 50 of the largest animals, as part of a culling program that has sparked anger among conservationists.
The three-month program, which ended last week, used baited lines attached to floating drums to catch sharks off popular beaches in Western Australia following a spate of fatal shark attacks in waters off the state in recent years.
The scheme, which was part of the state's $20 million shark mitigation policy, allowed for tiger, bull and great white sharks measuring longer than 10 feet (3 meters) hooked on the drum lines to be destroyed.
Some 50 tiger sharks longer than 10 feet were killed between January 25 and April 30. The largest one, which measured 14.8 feet (4.5 meters), was caught in February off Perth's Floreat beach.
