  abstract = {{I}nvestigating the drivers of fish assemblage trophic structure is a critical question, in order to better understand ecosystem functioning, predict the effects of perturbations and implement integrated management of exploited marine ecosystems. {E}cosystemic surveys enabled the determination of the trophic structure of the fish assemblages in three {F}rench marine ecosystems, namely the {E}astern {E}nglish {C}hannel, the {B}ay of {B}iscay and the {G}ulf of {L}ions, through the simultaneous collection of qualitative (stable isotopes and energy content) and quantitative (biomass) data. {I}n the {B}ay of {B}iscay and in the {G}ulf of {L}ions, pelagic primary production supported at least 80% of the fish biomass production, and explained the dominance of pelagic species, but with differences resulting from the different productivity. {T}he lower productivity in the oligotrophic {G}ulf of {L}ions led to a lower total biomass, energy density as well as the predominance of zooplankton-feeders. {I}n contrast, fluxes in the {B}ay of {B}iscay were sufficient to support a higher biomass of pelagic piscivores, and of species with higher energy content. {I}n the shallow {E}astern {E}nglish {C}hannel, the respective contributions of pelagic and benthic sources were similar. {B}entho-demersal species of higher trophic level dominated this assemblage, because of their ability to exploit both pathways. {R}esults of the present study confirmed that fisheries-focused surveys can be used as efficient platforms to address questions about ecosystem functioning. {H}ere, it confirmed the expected differences between ecosystems and the importance of primary production and environment as drivers of fish assemblage structure and functioning. {F}uture studies should nevertheless develop new methods to better assess the paramount role of low trophic level consumers.},
