Depredation in marine ecosystems is defined as the damage or removal of fish or bait from fishing gear by predators, and more specifically, by toothed whales. It leads to several negative consequences impacting conservation (bycatch of marine mammals, modification of their hunting behaviour), stock assessment (depredated fish not included in fish stock assessment) and fisheries
En halieutique, la déprédation se définit comme le prélèvement total ou partiel des poissons ou des appâts sur les engins de pêche par les requins, les odontocètes, les calmars ou les oiseaux. Ces interactions portent préjudice à la fois aux espèces impliquées (captures accidentelles, modification du régime alimentaire et de la stratégie de chasse), aux

Assessment of the efficiency of the physical protection of fish as mitigation measure to depredation by marine mammals in pelagic longlining, in: 3rd WIOMSA Scientific Symposium.

Depredation (damage or removal of fish from fishing gear by predators), raises concerns about conservation, fisheries profitability and stock assessment. There is a lack of knowledge about depredation impacting pelagic longline fisheries, especially in the southwest Indian Ocean (SWIO). Therefore, the development of accurate depredation indicators is needed. In La Reunion and Seychelles, local pelagic
Depredation, defined as the damage or removal of fish from fishing gear by predators, is an issue leading to negative impacts on animals and fisheries. Toothed whale depredation in pelagic longline fisheries targeting swordfish (Xiphias gladius) and tuna (Tuna spp) involves short-finned pilot whales (Globicephala macrorhynchus) and false killer whales (Pseudorca crassidens). In the Seychelles
Depredation is defined as the damage or removal of fish from fishing gear by predators, and is an issue leading to negative impacts on animals involved in depredation and fisheries. Depredation on pelagic longliners targeting swordfish (Xiphias gladius) and tuna (Tuna spp) involves short-finned pilot whales (Globicephala macrorhynchus), false killer whales (Pseudorca crassidens) and some
Depredation in marine ecosystems is defined as the damage or removal of fish or bait from fishing gear by predators. Depredation raises concerns about the conservation of species involved, fisheries yield and profitability, and reference points based on stock assessment of depredated species. Therefore, the development of accurate indicators to assess the impact of depredation
Depredation is defined as the damage or removal of fish from fishing gear by predators, and is a crucial issue leading to negative impacts on both animals involved in depredation and fisheries. Depredation in longline pelagic fisheries targeting swordfish (Xiphias gladius) and tuna (Thunnus spp.) involves short-finned pilot whales (Globicephala macrorhynchus), false killer whales (Pseudorca
Depredation is defined as the damage or removal of fish from fishing gear by predators and raises concerns about the conservation of marine protected species involved, fisheries yield and profitability, and stock assessment of target species. There is an obvious lack of knowledge about depredation impacting pelagic longline fisheries, especially in the southwest Indian Ocean.
La déprédation fait partie des interactions négatives entre les prédateurs marins et les pêcheries et se définit comme le prélèvement total ou partiel des poissons ou des appâts sur les engins de pêche par les requins, les odontocètes, les calmars ou les oiseaux. Ces interactions portent préjudice à la fois aux espèces impliquées (captures accidentelles,
