Update on Patagonian toothfish (Dissostichus eleginoides) losses in the bottom longline fishery due to the depredation by killer whales and sperm whales off the Kerguelen and Crozet Islands

Depredation caused by killer whales and sperm whales on the Patagonian toothfish (Dissostichus eleginoides) fishery off Kerguelen and Crozet EZs are amongst the most important in the Southern Ocean.
