The white-chinned petrel is the most common avian bycatch species in the Southern Ocean (Weimerskirch et al 1999; Gilman 2006; Robertson et al 2006; Birdlife International 2013). The high bycatch rate is due to seabirds, such as petrels, being attracted to pelagic and demersal longlines by bait and offal discarded from vessels (Gilman 2006; Bugoni et al 2008) and the high incident of spatial and temporal overlap between petrel foraging grounds and areas of fishery activity (Delord et al 2010b).
