  abstract = {{S}ardinella aurita is the most abundant small pelagic fish in the {S}enegalese-{M}auritanian region. {T}he success of its reproduction crucially depends on the local circulation as this determines whether larvae reach coastal nursery areas favorable to their survival or are dispersed into the open ocean. {A}s a first step towards evaluating sardinella vulnerability to climate-driven hydrodynamical changes, this study aims at underpinning how transport pathways drive optimal spatial and seasonal patterns for sardinella reproduction. {W}e have used two estimates of the {S}enegalese-{M}auritanian coastal seasonal circulation simulated by two hydrodynamical model configurations that differ in their forcing and topography. {N}ursery areas are determined by evaluating coastal retention with a {L}agrangian individual-based model that accounts for processes such as diel vertical migration and mortality as a result of lethal temperature exposure. {O}ur results suggest thatthe shelf zones located at the {A}rguin {B}ank (19.5 degrees {N}-21 degrees {N}) and south of {S}enegal (12 degrees {N}-14.75 degrees {N}) are highly retentive. {W}e find maximum retention rates in {J}uly-{A}ugust and {N}ovember-{D}ecember over the {A}rguin {B}ank; from {F}ebruary-{J}uly and {N}ovember-{D}ecember over the southern {S}enegalese shelf; and lower retention rates over the central region (14.75 degrees {N}-19.5 degrees {N}) that are locally maximum in {J}une-{J}uly when the upwelling weakens. {T}hese retention areas and their seasonality are in agreement with previously reported spawning patterns, suggesting that the {S}ardinella aurita spawning strategy may result from a trade-off between retention patterns associated with the seasonal circulation and food availability. {E}xposure to lethal temperatures, although not well studied, could be a further limiting factor for spawning. {T}he {L}agrangian analysis reveals important connectivity between sub-regions within and south of the system and hence underlines the importance for joint management of the {S}ardinella aurita stock.},
