  abstract = {{S}everal empirical and theoretical studies have shown how the exploitation of food sources, the choice of resting sites or other types of collective decision-making in heterogeneous environments are facilitated and modulated by social interactions between conspecifics. {I}t is well known that many pelagic fishes live in schools and that this form of gregarious behavior provides advantages in terms of food intake and predator avoidance efficiency. {H}owever, the influence of social behavior in the formation of aggregations by tuna under floating objects ({FOB}s) is poorly understood. {I}n this work, we investigated the collective patterns generated by different theoretical models, which either include or exclude social interactions between conspecifics, in the presence of two aggregation sites. {T}he resulting temporal dynamics and distributions of populations were compared to in situ observations of tuna behavior. {O}ur work suggests that social interactions should be incorporated in aggregative behavior to reproduce the temporal patterns observed in the field at both the individual and the group level, challenging the common vision of tuna aggregations around {FOB}s. {O}ur study argues for additional data to further demonstrate the role of social behavior in the dynamics of these fish aggregations. {U}nderstanding the interplay between environmental and social factors in the associative behavior of fish with {FOB}s is necessary to assess the consequences of the widespread deployment of artificial {FOB}s by fishermen.},
