In 1994, an experimental longline fishery for hake Merluccius spp. commenced in the shelf waters off South Africa. Participants were required to record any birds caught, and these data were supplemented by ship-based observers on several vessels. Longlines are set at night, and the white-chinned petrel Procellaria aequinoctialis was the only seabird species caught while attempting to scavenge bait during gear setting. Small numbers of great shearwaters Puffinus gravis and pintado petrels Daption capense were killed during hauling operations. The hake longline fishery is estimated to kill 8000+/-6400 white-chinned petrels a year in South African waters at a rate of 0.44 birds per 1000 hooks. This represents
