Drumlines

Drumlines is a term with more than one meaning, depending on context. In music, a drumline refers to the percussion section of a marching band, drum corps, or similar ensemble. It typically includes snare drummers, tenor drums, and bass drummers, and is responsible for rhythmic drive, timekeeping, and the visual elements of a performance. The drumline may perform in parades, field shows, and competitions and is often a prominent part of a group’s identity.

In fishing and wildlife management, a drumline is a device used to capture large predatory species, notably sharks. It consists of a floating buoy, or drum, attached to lines with baited hooks set along the length. The drum marks the location so vessels can locate and retrieve the gear later. Drumlines are used in some regions for commercial fishing and, under certain shark-control programs, to reduce human–shark encounters. They are controversial due to ecological impacts, including bycatch of non-target species, animal welfare concerns, and debates about efficacy. Regulation varies by country and region, with some areas restricting or phasing out drumlines in favor of non-lethal methods such as nets, exclusion devices, or drone-based monitoring.
