Advantages
The Drum Lines first started to come into use in Queensland Australia in 1962. During this time they were just as successful in reducing the frequency of shark attacks as the shark nets on the beaches in New South Wales and KwaZulu-Natal. While shark nets and drum lines share the same purpose, drum lines are more effective at targeting the three sharks that are more dangerous to swimmers. Those three sharks are the bull shark, tiger shark and great white shark. Drum Lines physically attract sharks with its bait while the shark nets allow the sharks to swim over or around it. Shark nets have a large amount of bycatch including: Dugongs, Dolphins, Sea Turtles and several harmless species of sharks. The bycatch, or unintended catches, of the drum lines are a lot less likely than those of the shark nets.The drum lines are more effective because they reduce the amount of shark attacks just as effectively as shark nets, with a major reduction in bycatch.
