  abstract = {{T}he link between trophic ecology and metal accumulation in marine fish species was investigated through a multi-tracers approach combining fatty acid ({FA}) and stable isotope ({SI}) analyses on fish from two contrasted sites on the coast of {S}enegal, one subjected to anthropogenic metal effluents and another one less impacted. {T}he concentrations of thirteen trace metal elements ({A}s, {C}d, {C}o, {C}r, {C}u, {F}e, {L}i, {M}n, {N}i, {P}b, {S}n, {U}, and {Z}n) were measured in fish liver. {I}ndividuals from each site were classified into three distinct groups according to their liver {FA} and muscle {SI} compositions. {T}race element concentrations were tested between groups revealing that bioaccumulation of several metals was clearly dependent on the trophic guild of fish. {F}urthermore, correlations between individual trophic markers and trace metals gave new insights into the determination of their origin. {F}atty acids revealed relationships between the dietary regimes and metal accumulation that were not detected with stable isotopes, possibly due to the trace metal elements analysed in this study. {I}n the region exposed to metallic inputs, the consumption of benthic preys was the main pathway for metal transfer to the fish community while in the unaffected one, pelagic preys represented the main source of metals. {W}ithin pelagic sources, metallic transfer to fish depended on phytoplankton taxa on which the food web was based, suggesting that microphytoplankton (i.e., diatoms and dinoflagellates) were a more important source of exposition than nano- and picoplankton. {T}his study confirmed the influence of diet in the metal accumulation of marine fish communities, and proved that {FA}s are very useful and complementary tools to {SI}s to link metal accumulation in fish with their trophic ecology.},
