Sea Turtle and Artisanal Cerco-Fixo Fishing Interactions in Cananéia, South Coast of São Paulo

Abstract

"Sea turtles are reptiles that occur on the Brazilian coast, mainly on nesting and feeding grounds. The consumption of turtle meat and eggs is an ancient habit in many coastal communities around the world. The main dangers that threaten these species are the increase in fishing and the drastic changes in the environment. This study aimed to elucidate the interaction between the artisanal fishermen and the sea turtles in Cananéia, São Paulo state, Brazil. Local fishermen had developed an artisanal trap to fish, the “cerco-fixo”, and through interviews and illustrations, as well as by accompanying the fishermen’ daily activities, three main aspects were verified:(i) the perception of the fishermen about the sea turtles; (ii) the identification of species and morphological characteristics of these animals; and (iii) a description of the incidental bycatch of sea turtles in these traps. The data indicates that this fishing trap is not harmful to the sea turtles. Location of traps can influence the capture of these animals, particularly those traps placed on rocky shores and other similiar points."
