What is a lethal drum line?
A drumline is a fishing apparatus that consists of a baited hook suspended from buoys and anchored to the ocean floor. Hook size and design for the trial program were chosen to target large sharks and to minimise bycatch.
Do Drumlines hurt sharks?

How does the shark drum line in NSW work?

What are drum lines and what do they do?
Drum lines are a pretty basic fishing device involving a large baited hook attached to a rope (or metal trace) which is then attached to a floating buoy, or the seafloor.
