  abstract = {{L}arge marine predators feeding on fish caught on fishing gear, referred to as 'depredation', occur in a wide range of fisheries worldwide. {D}epredation can result in negative ecological and socio-economic impacts, leading to conflict between fishers and depredating species. {H}owever, depredation remains understudied in many fisheries, and this hampers the development of effective mitigation solutions. {I}n this study, 21 years of fishing data (2002-2022) were used to assess shark and odontocete depredation in the pelagic tuna longline fishery of {N}ew {C}aledonia. {U}sing generalized linear models, the year, season, effort, soaking time, and vessel were identified as variables significantly influencing the probability of depredation to occur. {R}esults showed that while shark depredation occurred more frequently than odontocete depredation (58.5% vs. 9.2% of the longline sets), they damaged a lower proportion of fish (3.9% vs. 12.3%) over the study period. {U}nlike sharks, odontocetes selectively depredate tuna, with their highest occurrence during periods of high tuna catch rates, suggesting a co-occurrence with fishing activities. {T}ogether, these results indicate that depredation in the {N}ew {C}aledonian fishery is high compared to other regions and provide essential information on the dynamics and impacts of the issue as a basis for considering management and mitigation options.},
