Haul mitigation devices aim to scare seabirds away from risk areas when lines are hauled. Recent experimental work has demonstrated that simple and cheap hauling mitigation devices have the potential to reduce bycatch risk to seabirds during longline hauling with minimal impact on fishing operations of small vessels. Examples trialed include the following:
- a rail mounted mitigation device, fitted behind the hauling station on the port side of the vessel
- a horizontal pole suspended a vertical dropper 3.5 m outside of the vessel, aft of the hauling station approximately two metres forward of the transom, on the starboard side of the vessel
