Resumen: Experiments were conducted to investigate the effect of differences in the spatial distribution of food on the aggressive behaviour of juvenile white‐seabream, Diplodus sargus cadenati, both in the presence and in the absence of food. The groups of fish receiving spatially fixed food displayed less aggression than those receiving spatially variable food. The period (before, during, or after feeding) during which aggressiveness is measured also has influence in the results. During the prefeeding and postfeeding periods (absence of food), groups that were fed with food spatially fixed displayed less aggression than those that received spatially variable food. However, when food was present there were no differences in the number of aggressive acts carried out by fish groups in both environments. The aggressiveness shown by the groups of fish was always more pronounced during the postfeeding period than during the prefeeding period. The dominant fish was more aggressive when food was spatially fixed, and especially when food was present. Therefore, the subordinates were more aggressive when food was spatially variable and particularly when food was present and during the postfeeding period.
