  abstract = {{S}ardinella aurita is an overexploited small pelagic fish and a key species in {S}enegal at socioeconomics level, nevertheless the growth parameters which is a good indicator of fish stressors, have not been updated since 30 years. {I}n this work, we analysed {S}. aurita (n = 32 300) age and growth in {S}enegal taking into account the tropical seasonality. {G}rowth parameters are then compared with those previously obtained in the literature on the same geographical area (since 60 to 34 years) and more widely in different locations in tropical {N}orth {A}tlantic and {M}editerranean {S}ea. {T}he results show a significant difference of growth parameters in {S}enegal since thirty years, indeed growth of {S}. aurita became slower and its maximum size has significantly decreased. {T}he comparison of {S}. aurita variability in growth performance reported in {M}auritania-{S}enegal coast, as well as in {M}editerranean {S}ea and {E}astern/{W}estern {A}tlantic {O}cean reveals a significant influence of environmental parameters and/or the level of exploitation. {I}n one hand in tropical {A}tlantic, {S}. aurita growth in {E}astern {C}entral is similar to the one reported in {W}estern {C}entral, while {S}. aurita growth is rather slow in {M}editerranean {S}ea where, vs tropical {A}tlantic, {S}ea temperature and prey availability are lower. {O}n the other hand, in the {A}tlantic {W}estern {C}entral, where the fishing pressure on the stock is lower over the last decade vs {A}tlantic {E}astern {C}entral, an increase in asymptotic length is observed, while in the {M}editerranean {S}ea and {A}tlantic {E}astern {C}entral, where the fishing pressure is higher, the asymptotic length has drastically decreased. {W}e assume that the fishing pressure and the climate change, or a combination of both, have an effect on the biological parameters of {S}. aurita.},
