  abstract = {{A}lthough little is known about the individual-level mechanisms that influence small pelagic fish species' reproductive strategy, {M}ullon et al. [{M}ullon, {C}., {C}ury, {P}., {P}enven, {P}., 2002. {E}volutionary individual-based model for the recruitment of anchovy ({E}ngraulis capensis) in the southern {B}enguela. {C}anadian journal of {F}isheries and {A}quatic {S}ciences 59, 910-922] showed that the observed anchovy spawning patterns in the southern {B}enguela {C}urrent system off {S}outh {A}frica could be accurately reproduced by simulating a natal homing reproductive strategy, i.e. individuals spawning at their natal date and place. {H}ere we used a similar method, i.e., an individual-based model of the natal homing reproductive strategy, and applied it to other upwelling systems: the northern {H}umboldt {C}urrent system off {P}eru, the southern {H}umboldt {C}urrent system off {C}hile and the central {C}anary {C}urrent system off {M}orocco. {W}e investigated the spatial (horizontal and vertical) and seasonal spawning patterns that emerged after applying different environmental constraints in the model, and compared these to observed spawning patterns of sardine and anchovy in their respective systems. {T}he selective environmental constraints tested were: ({I}) lethal temperature; (2) retention over the continental shelf-, and (3) avoidance of dispersive structures. {S}imulated horizontal spatial patterns and seasonal patterns compared reasonably well with field data, but vertical patterns in most cases did not. {S}imilarly to what was found for the southern {B}enguela, temperature was a determinant constraint in the southern {H}umboldt. {T}he shelf retention constraint led to selection of a particular spawning season during the period of minimum upwelling in all three of the upwelling regions considered, and to spatial patterns that matched observed anchovy spawning off {C}hile and sardine spawning off {M}orocco. {T}he third constraint, avoidance of dispersive structures, led to the emergence of a spawning season during the period of maximum upwelling off {C}hile and {M}orocco, but not in {P}eru. {T}he most accurate representation of observed spatio-temporal spawning patterns off {P}eru was achieved through a combination of shelf retention and non-dispersion constraints.},
