  3. What is the W.A. shark cull? • State government policy of capturing and killing large sharks by using baited drum lines • 3 month program • 72 drum lines across 200 km • Target: Great Whites, Bull sharks, and Tiger sharks • Caught: 172 • Killed: 50

  4. Important to remember: shark attacks are random events!

  5. Opposition • Activists removed bait from drum lines • Protestors gathered on the beach on two occasions ranging in the thousands

  6. Will it work? • Theory: fishing close to popular swimming beaches deceases local populations, thus reducing human interactions • Evidence supports localized decline… but not in all species • White sharks and tiger sharks are highly mobile • No white sharks captured, mostly tiger sharks • 70% of catch weren't large enough to be considered a threat or were bycatch

  7. Alternative strategies • Satellite-linked shark tagging • Personal shark protection • Electronic shark deterrents • Camouflage wetsuits
