Última The aggregation of tuna around floating objects: What could be the underlying social mechanisms? ArchiMer Robert, Marianne; Dagorn, Laurent; Deneubourg, Jean Louis. Several 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. It 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. However, the influence of social behavior in the formation of aggregations by tuna under floating objects (FOBs) is poorly understood. In this work, we investigated the collective patterns generated by different theoretical models, which either include or exclude social interactions between conspecifics, in the...

The aggregative behaviour of the dolphinfish (Coryphaena hippurus) is studied in order to improve our knowledge of the mechanism involved in the association of this species with the floating objects and to evaluate its potential impact in term of exploitation, targeted or not. This PhD thesis is composed of four chapters. Through an extensive analyze of the literature, the first chapter takes stock of the present knowledge on the FADs, on the aggregative behaviour of pelagic fish and on the dolphinfish. The second chapter deals specifically with the aggregative behaviour of the dolphinfish by the way of acoustic tagging of fish carry out during offshore campaigns around drifting FADs. The feeding habits of the dolphinfish around FADs are the main purpose...
