  abstract = {{T}he {F}lagfin mojarra, {E}ucinostomus melanopterus, is a marine spawner whose young individuals are common in the {S}ine {S}aloum inverse estuary ({S}enegal). {T}he species offers the opportunity to study both the use of the estuarine nursery resources and the impact of the particular environment of the inverse estuary on these resources. {T}his will lead to a better understanding of the functioning of the nursery. {W}e investigated the resources used by juvenile {F}lagfin mojarra by coupling stomach contents and stable isotopes methods. {Y}oung {F}lagfin mojarra feed on a wide range of invertebrates. {D}iet changed from copepods in the smallest size class (10-40 mm), to a range of invertebrates including amphipods, insect larvae, polychaetes and mollusc in the medium size class (up to 60 mm) and mainly polychaetes for individuals >60 mm in size. {I}n mangrove habitats with moderate salinity, the diet was dominated by polychaetes and decapod larvae (crabs) whereas in habitats with higher salinity, diet was dominated by amphipods. {I}n very hypersaline areas with scarce mangroves, diet comprised benthic copepods, chironomid larvae and ostracods. {T}his agreed with a clear change in delta {C}-13 measured in fish sampled at downstream or upstream sites. {C}omparison with signatures of primary producers suggested that the local food web exploited by young {F}lagfin mojarra is mainly based on phytoplankton in the downstream mangrove area, and mainly on benthic microalgae in the upstream hypersaline area. {A}s in many studies considering the food webs in mangrove, mangrove was not identified as a major contributor to the food web exploited by {E} melanopterus. {T}his needs further investigation particularly because the exportation of estuarine materials to the sea is limited in an inverse estuary.},
