Since the end of whaling, interaction with human activities, such as fishing, is one of the main threats to the conservation of the southern right whale in Brazil. Interviews were conducted with fishermen in the Right Whale Environmental Protection Area (Área de Proteção Ambiental da Baleia-Franca, APA-BF) to identify potential areas of interaction with fishing activity in this sustainable use conservation unit. Using these data, the areas were delimited by the 95% and 50%, fixed kernel density estimator (KDE) method. From published data of the distribution of the southern right whale, using the same methodology, the overlap of the estimated areas was calculated. In total, 248.22 km² of interaction areas were identified, of which 34.15 km² (KDE whales 50% x KDE fishing 50%) are considered high interaction and 214.07 km² are medium interaction (KDE whales 95% x KDE fishing 50%).
