    Depredation is observed in many places within the convention area and is an increasing concern for fishery. Killer whale and sperm whales are the two odontocetes species mainly responsible for this issue. One of the key point to understand the process of depredation is to use photo-identification, pictures taken by observers on board longline vessels targeting toothfish have been analysed. Several photo-identification catalogues have been produced as a reference to identify individuals.
