  abstract = {{S}kipjack tuna (#{K}atsuwonus pelamis$) contributes approximately to 70% of the total tuna catch in the {P}acific {O}cean. {T}his species occurs in the upper mixed-layer throughout the equatorial region, but the largest catches are taken from the warmpool in the {W}estern equatorial {P}acific. {A}nalysis of catch and effort data for {US} purse seine fisheries in the {W}estern {P}acific has demonstrated that one of the most successful fishing grounds is located in the vicinity of a convergence zone between the warm (greater than 28-29° {C}) low-salinity water of the warmpool and the cold saline water of equatorial upwelling in the central {P}acific ({L}ehodey et al, 1997). {T}his zone of convergence, identified by a well-marked salinity front and approximated by the 28.5° {C} isotherm, oscillates zonally over several thousands of km in correlation with the {E}l {N}ino-{S}outhern {O}scillation. {T}he present study focuses on the prediction of skipjack tuna forage that is expected to be a major factor in explaining the basin-scale distribution of the stock. {I}t could also explain the close relation between displacements of skipjack tuna and the convergence zone on the eastern edge of the warmpool. {A} simple bio-geochemical model was coupled with a general circulation model, allowing reasonable predictions of new primary production in the equatorial {P}acific from mid-1992 to mid-1995. {T}he biological transfer of this production toward tuna forage was simply parameterized according to the food chain length and redistributed by the currents using the circulation model. {T}una forage accumulated in the convergence zone of the horizontal currents, which corresponds to the warmpool/equatorial upwelling boundary. {P}redicted forage maxima corresponded well with high catch rates.
