Killer whale (Orcinus orca) interactions with longline fisheries in New Zealand waters
Killer whales (Orcinus orca) interact with longline fisheries around the world, however they have not previously been reported taking fish off longlines in New Zealand waters. Two new killer whale prey species (school shark, Galeorhinus galeus and blue-nose, Hyperoglyphe antarchia) have been recorded. A great deal of effort has been applied, worldwide, to reduce killer whale-fishery interactions, but few methods are successful. Fishers in New Zealand have used ‘tuna bombs’ and shooting.
