  abstract = {{S}mall pelagic fishes play important ecological roles in marine ecosystems, constitute some of the most economically valuable fisheries resources, and play a vital role in {W}est {A}frican food security. {O}ften living in upwelling regions, these species appear to have developed mechanisms to cope with environmental variability, such as opportunistic reproductive tactics, enhancing their growth performance, or increasing their egg production by following the more predictable system attributes of seasonal cycles. {T}o test this hypothesis, we investigated size-dependent patterns of the two growth mechanisms (i.e., growth rate) of two {W}est {A}frican small pelagic populations ({E}thmalosa fimbriata and {S}ardinella maderensis) in upwelling environments. {T}hese results were discussed with other areas in {A}frican tropical {A}tlantic waters. {T}he monthly mean length of both species showed a large variation over the study period. {B}ased on the fish length-frequency data and a coastal upwelling index, we found that the growth peaks of the species tended to occur during the most intense periods of upwelling ({M}arch-{A}pril). {T}his study showed a significant decrease in size compared with other species found in other regions. {I}t demonstrates how the geographical distribution of the same species, together with location-specific variation in temperature and food, can combine to determine local and regional growth responses in pelagic fish. {C}hanges in growth rate may be an adaptive tactic in response to environmental change, as well as phenotypic plasticity in fish. {T}his knowledge is essential to predict future changes in fish productivity and distribution vs. climate and to provide effective advice for ecosystem-based management.},
