Night-setting Factsheet (May 2019)
Seabirds generally detect food at close range by sight. Consequently, they feed mostly during daylight hours and are least active at night. Setting lines at night is therefore a simple but highly effective way of reducing seabird bycatch and bait loss. Although the majority of vulnerable seabirds are inactive at night, some species, such as the White-chinned Petrel, actively forage at night. Night-setting is therefore less effective for these species.
