  abstract = {{E}cological knowledge of food web interactions within pelagic marine communities is often limited, impairing our capabilities to manage these ecologically and economically important marine fish species. {H}ere we used stable isotope analyses to investigate trophic interactions in the pelagic ecosystem of the northwestern {M}editerranean {S}ea during 2012 and 2013. {O}ur results suggest that {E}uropean sardine, {S}ardina pilchardus, and anchovy, {E}ngraulis encrasicolus, are consumers located at relatively low levels of the pelagic food web. {U}nexpectedly, the round sardinella, {S}ardinella aurita, appeared to be located at a higher trophic level than the other small pelagic fish species, although previous studies found similarity in their diets. {I}sotope data suggested that trophic niches of species within the genera {T}rachurus spp. and {S}comber spp., were distinct. {A}tlantic bonito {S}arda sarda, {E}uropean hake {M}erluccius merluccius and {E}uropean squid {L}oligo vulgaris, appeared to feed at higher trophic levels than other species. {D}espite some intraspecific seasonal variability for some species, community trophic structure appeared relatively stable through the year. {T}hese data provide an important step for developing models of food web dynamics in the northwestern {M}editerranean {S}ea.},
