  abstract = {{W}ith the persistence of a drought since the late 1960s, some {W}est {A}frican estuaries became permanently reversed in term of salinity gradient and hypersaline waters are present in their upstream part (salinity >60). {T}o understand the mechanisms regulating fish recruitment intensity in these estuaries and evaluate the consequences of freshwater shortages on juvenile habitat quality, a growth study was conducted in the {S}aloum hypersaline estuary ({S}enegal). {T}he {M}ugilidae fish family, highly representative of estuarine environments, was targeted and several species sampled ({C}helon dumerili, {M}ugil bananensis and {M}. cf. curema sp. {M}). {J}uveniles were sampled monthly all the year round in three areas of the estuary exhibiting strongly contrasted habitat conditions. {O}tolith sections were used to estimate the ages, reconstruct growth trajectories, estimate the duration of the oceanic larval phase, and evaluate juvenile growth variability along the salinity gradient. {A}nalyses revealed that the temporal recruitment variability of {C}. dumerili, with 2 annual cohorts, was not mainly induced by growth-selection mechanisms, but probably more by predation pressures. {J}uveniles exhibited significantly faster growth rates in the lower salinity suggesting that benthic food availability was a strong factor controlling habitat quality of early juveniles. {S}alinity had also a clear impact when reducing the growth in hypersaline conditions and/or selecting slower growing individuals. {M}oderate freshwater inputs positively affected the nursery function of the estuary for mugilids by enhancing the productivity of the first trophic levels. {I}n a long term, the global change could have an impact of the mugilid fishery and its management.},
