  abstract = {{I}n order to assess the latitudinal variability in growth of the eastern {A}tlantic skipjack ( {K}atsuwonus pelamis), conventional tagging data collected by the {I}nternational {C}ommission of the {C}onservation of {A}tlantic {T}unas ({ICCAT}) since the 1960s are reanalyzed using a modified version of the von {B}ertalanffy-{F}abens growth model. {A}n analysis of the latitudinal patterns of recaptures showed that the lowest mixing rate between northern and southern regions was evidenced at 10 degrees {N} {L}atitude. {S}ince it is theoretically admitted that growth parameters {L}-infinity and {K} are negatively correlated, we substituted {L}-infinity into the growth equation model by a simple bioenergetic function of {K} fitted from existing studies on skipjack growth parameters. {T}he likelihood for the meta-analysis of growth is combined with the likelihoods from the two regional tagging data with the aim of estimating simultaneously {K} in both areas and to transfer adequately uncertainties associated with the different data sets. {F}rom this study, it was showed that fish inhabiting waters south of 10 degrees {N} latitude can be expected to grow generally larger but at slower rate than in the {N}orth ({L}-infinity = 112.34 cm vs. 89.38 cm, and {K} = 0.14 vs. 0.38, respectively). {O}ur results are consistent with the range of growth estimates obtained in the {A}tlantic {O}cean and in different parts of the {W}orld's oceans. {I}n contrast, the estimates of {L}-infinity and {K} done in the {S}enegalese region in the 1980s within the framework of the {S}kipjack {Y}ear {P}rogram, and traditionally applied by {ICCAT}, are not supported by the present study. {T}he findings concerning the phenotypic plasticity exhibited by growth of skipjack among latitudinal regions suggest potential differences in fish population productivity and consequently imply that non-conventional stock assessment methods such as catch-at size/growth transition matrix per region could be used to assess the responses of skipjack to exploitation.},
