The focus of this master thesis lies on the multiple uses and appropriations regarding a space - the fishing shed - through a specific situation: the conflict involving fishermen who practice different fishing gear and barraqueiros, in Piratininga Beach, Niterói, RJ. Firstly, from the fieldwork, I describe the locality and the actors involved, as well as the disputes that occur on the beach, especially as summer approaches. Posteriorly, I try to answer, through concepts and theories, the questions raised by empirical research, regarding the notion of public space in Brazil, the representations about the beach, the interests at stake and the meanings attributed to that place. Finally, I conclude with an interpretive analysis of the conflict that is present in the political structure of the group and the mechanisms used to manage it.
