  abstract = {{M}angrove ecosystems have long been considered essential habitats and are commonly viewed and referred to as "nursery areas". {T}hey are highly sensitive to, climate change, and environmental transformations in these ecosystems are expected. {T}he {S}ine {S}aloum estuary is a case of a system affected by global climate change where reduced precipitation and temperature increase have resulted in an inversion of the salinity gradient. {W}ithin the estuary, the composition and structure of the larval fish community related to environmental parameters were investigated using neuston and ring trawl nets. {L}arval fishes were sampled at 16 stations distributed along a salinity and distance-to-the-sea gradient during four field campaigns ({N}ovember 2013, {F}ebruary, {J}une, and {A}ugust 2014) covering an annual cycle. {T}his is the first study documenting the spatial and temporal assemblages of fish larvae in an inverse estuary. {T}he total of 41 taxa representing 24 families and 34 genus identified in this study was lower than that of other tropical estuaries. {C}lupeidae spp. was the dominant taxon, accounting for 28.9% of the total number of fish larvae caught, followed by {G}erreidae spp. (21.1%), {H}yporamphus picarti (18.8%), {D}iplodus bellottii (8.9%), {H}ypleurochilus langi (4.8%), {M}ugilidae spp. (4.4%), and {G}obiidae sp.1 (3.5%). {A} total of 20 taxa were recorded within the upper estuary region, whereas 29 and 37 taxa were observed in the middle and lower reaches, respectively. {W}hile larval fish were captured at all sites and during all seasons, abundances and richness decreased with increasing salinity. {L}arval fish assemblages also showed a clear vertical structure corresponding to three distinct water strata. {S}alinity, water temperature, and dissolved oxygen were the variables that best explained the spatial and temporal differences in larval fish assemblages. {I}t is difficult to forecast the future situation for this system but so far, compared to other mangrove estuarine systems, we have observed the loss of freshwater species in favour of species of marine origin. {T}he information provided in the present study is a contribution to the knowledge of tropical biodiversity and modifications of the ichthyoplankton communities in the context of climate change and future green fund action.},
