  abstract = {{P}lastic pollution is present in most marine environments; however, contamination in pelagic predators, including species of economic interest, is still poorly understood. {T}his study aims to access the macro-and microplastic contamination in tuna and large pelagic species and verify whether a trophic transfer occurs from prey to tunas captured by two fleets in the {S}outhwestern {T}ropical {A}tlantic ({SWTA}). {W}e combined different methodological approaches to analyse the intake of macro-and microplastics. {I}n addition to examining the plastics in the fish' stomachs, we investigated the contamination in the prey retrieved from the guts of predators. {A} low frequency of occurrence (3%) of macroplastic was detected in the tuna and large pelagic species; conversely, we observed a high frequency of microplastic in the tuna's stomachs (100%) and prey analysed (70%). {W}e evinced the trophic transfer of microplastics by analysing the ingestion rate of particles in prey retrieved from the tuna stomachs. {I}n the 34 analysed prey, we detected 355 microplastic particles. {T}he most contaminated prey were cephalopods and fishes of the {B}ramidae family. {T}he most frequent microplastic shapes in both prey and tuna stomachs were foams, pellets and fibres (<1 mm). {A} variety of polymers were identified; the most frequent were styrene-butadiene rubber ({SBR}), polyamide ({PA}), polyethylene terephthalate ({PET}) and polyethylene ({PE}). {O}ur findings enhance scientific knowledge of how the ecological behaviour of marine species can affect microplastic intake.},
