Abstract

Interactions between the longline toothfish (Dissostichus eleginoides) fisheries and cetaceans in the Southern Ocean have been registered over three decades. Two species primarily involved in these interactions are the sperm whale (Physeter macrocephalus) and the orca (Orcinus orca). Both species have been registered depredating on the longlines and fisheries have been substantially affected by the noticeable decrease on the catch. In this review, we summarized current knowledge about these interactions occurring south of 47°S in the industrial fleet. At present, interactions occur predominantly with the orca and in a lower extent with the sperm whale, after the modification of the fishing gear that diminished the depredation of the sperm whale. To date, many alternatives have been tested to repel cetaceans, including physical modifications of the fishing gear, acoustic devices, and changes in the fishing practices by the vessels, yet none seem effective. In the future, not one solution but a complex mix of actions must be coordinated effectively between the fishing operators, researchers, fishery engineers and State Public Institutions in order to diminish these interactions.
