Abstract : The present dissertation investigates the practice of everyday life and sociabilities during the fishing season of the mullet fish (May to July) on Tesoura Beach in Laguna, located at southern coast of Santa Catarina. In this beach the artisanal fishing with the aid of dolphins takes place. The artisanal fishermen position themselves in an organized way in the water, waiting for a signal of the dolphin. The marine mammal directs the shoal until it is cornered in front of the fishermen, when this happens the dolphin jumps, such movement is interpreted by the human as the right time to throw the jar and capture the mullet fish. The everyday life of this peculiar fishing articulates several activities in the Tesoura Beach and congregates different social actors in this public space. I present the artisanal fishermen, their organizations, rules, differences, conflicts and the commercialization of fish carried out on the spot. As well as, the non-fishermen, characterized as spectators of the spectacle that became the artisanal fishing with the dolphin´s aid of and in the Tesoura Beach. Through the uses and appropriations of the public space I reach the social construction of this practiced place of fishing and sociabilities.
