Última Interactions between cetaceans and artisanal fishermen from Ilhéus, Bahia - Brazil Biota Neotropica Seminara,Cecilia Inés; Barbosa-Filho,Márcio Luiz Vargas; Pendu,Yvonnick Le. Abstract: Ethnobiological studies are necessary to understand the relationships between fishers and cetaceans. The aim of this study was to describe the interactions between cetaceans and artisanal fishers and the possible conflicts that can arise as a result. Semi-structured interviews were conducted from February to September 2017 with 35 fishermen from the municipality of Ilhéus, Brazil. All fishermen reported both positive and negative interactions with Megaptera novaeangliae, Tursiops truncatus and Sotalia guianensis and only negative interactions with Balaenoptera acutorostrata (n=14) and Stenella frontalis (n=4). The positive interactions consisted of playful relationships and collaborative fishing. Negative interactions (bycatch, entanglement,...

Ano: 2019 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1676-06032019000400202 Spatial distribution and activities of the estuarine dolphin Sotalia guianensis (van Bénédén, 1864) (Cetacea, Delphinidae) in Pontal Bay, Ilhéus, Bahia, Brazil Biota Neotropica Santos,Urânia Amaral dos; Alvarez,Martin Roberto; Schilling,Ana Cristina; Strenzel,Gil Marcelo Reuss; Pendu,Yvonnick Le. We analyzed the influence of time, tide and water depth on the activity and spatial distribution of estuarine dolphins Sotalia guianensis in Pontal Bay, Ilhéus, Brazil. Direct observations were carried out at four fixed points from January to December of 2006. Estuarine dolphins were sighted in 11 out of 12 months and in 30% of 181 sampling periods. The average group size, which was 3.75 ± 1.59 (n = 64), did not vary significantly by month (Kruskal-Wallis, H = 10.6729; p = 0.3836). Infants and adults represented 18 and 82% of the individuals whose age we were able to determine, respectively. Estuarine dolphins were more frequently present than expected in areas deeper than 3 m (regression GLM, z = 3.773; p = 0.0002). The animals were more frequently...
