  abstract = {{S}uccessful recruitment in small pelagic fish populations inhabiting upwelling zones is subject to variation in fecundity and is driven by spatial and temporal fluctuations in environmental conditions, that is, mainly sea surface temperature, salinity and food availability. {T}hese fluctuations in abiotic factors have stimulated small pelagic fish populations to exhibit specifically adapted spawning tactics. {T}o better understand to what extent a short-lived exploited fish species such as bonga shad {E}thmalosa fimbriata has adapted to an upwelling environment, we have investigated the interrelationship between upwelling intensity as a proxy for productivity and population fecundity by means of a virtual population analysis. {W}e found that females of intermediate size contributed significantly more eggs to the population's fecundity than smaller or larger ones. {O}ur model results further indicate that {E}. fimbriata exhibits a spawning preference at water temperatures of around 25 degrees {C} and upwelling intensities of around 2.5 m(3) s(-1) m(-1). {H}ence, we hypothesize that climate change-driven increases in sea temperatures and modifications of upwelling-favourable winds could significantly impact the species' reproductive biology. {T}o understand how climate change might impact fisheries, spawning tactics of small pelagic fishes are important to assess as well as their recruitment success. {S}uch information is particularly relevant in countries where the fishery is critical at socio-economic level, to better implement fisheries management addressing multiple stressors.},
