Resumo: 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.

Estas manifestações agressivas foram executadas tanto por machos quanto por fêmeas, apenas nas proxiidades da linha de pescadores. Os coeficientes de Schaller demonstraram que o nível de associação entre pares de delfins, interagindo com a pesca de tainhas no sul do Brasil, é extremamente baixo. Isto nos leva a duas hipóteses complementares: há uma relativa dominância intraespecífica durante as interações com a pesca de tainhas e esta leva a uma exclusividade temporária na utilização dos recursos.Universidade Federal de Santa Catarina1998-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21921Biotemas; v. 11 n. 2 (1998); 165-1712175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21921/19945Copyright (c) 1998 Paulo C.
