Abstract

Intraspecific threat behavior of Tursiops truncatus during dolphin-human cooperative fishing of mullets in southern Brazil, are described and discussed. These aggressive manifestations were observed only near the line of fishermen and were equally performed by males and females. Schaller's coefficients demonstrate that the level of intraspecific association between pairs of dolphins, interacting with the mullets fisheries in southern Brazil is extremely low. This allows two compementary hypotheses: there is a relative degree of intraspecific dominance during the interactions; this promotes a temporary exclusiveness in the use of food resources.
