  abstract = {{E}thmalosa fimbriata ({B}owdich 1825) is a small, often overexploited, pelagic fish species that occurs off tropical and subtropical coastlines. {I}t constitutes the main catch of artisanal fisheries off the coast of {W}est {A}frica. {W}e examined growth rates and reproductive characteristics of {E}. fimbriata off {T}he {G}ambia and other coastal areas to determine how they relate to variations in environmental characteristics of coastal waters. {U}sing fish length-frequency data and a coastal upwelling index, it was found that recruitment of {E}. fimbriata tends to occur during periods of intense upwelling when nutrient-rich water is brought to the surface. {T}he evolutionary trait of peak reproduction corresponds to low sea surface temperature periods. {W}e hypothesize that {E}. fimbriata takes advantage of the higher zooplankton productivity in coastal waters when upwelling brings nutrient-rich water to the surface (i.e., it increases its growth rate and accumulates energy reserves for spawning). {G}rowth performance appears to be intensely dependent on environmental conditions. {T}he timing of spawning seems to occur when food (zooplankton) is most available to supply the energy requirements adults need for spawning and early development of larvae. {E}nvironmental changes seem to significantly affect {E}. fimbriata growth and reproduction, which endorses their high phenotypic plasticity.},
