This study aimed to identify the possible impact of fishing activities and boat collision on the population of the estuarine dolphin (Sotalia guianensis) through the methodologies of ethnobiology and photo-identification the Bay of Sepetiba, Rio de Janeiro State, Brazil. Data were collected through interviews with fishermen ethnobiological local sightings by photo-identification. The results show that occurs enmeshing of animals with nets used in fishing and accidents among the dolphins and vessels used in this activity. Furthermore, the results confirmed that the uses of these techniques are complementary methods for the identification of possible impacts caused by artisanal fisheries. The information gathered in this study contributes to define strategies for dolphin conservation in order to reduce the negative anthropic impacts on the species’ natural population.Downloads
