Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/861The interaction between fishery and cetacean populations contemplates positive and negative aspects. Therefore, the bycatch represents a high risk to cetacean conservation in the whole world. Small coastal cetaceans are more vulnerable to interactions with gillnets. Hitherto, the lack of knowledge related to the interactions between fisheries and small cetaceans at the Brazilian North Coast, added to the high fishing potential of the region, motivate studies and monitoring of this activity. In order to begin the effort to the knowledge of fishery and the interactions with small cetaceans at the Pará State, there were made semi-structured interviews at the east coast of Ilha de Marajó and APA Algodoal/Maiandeua from November 2009 to November 2010. The questionnaires were applied with 58 and 30 artisanal fishermen in the two respectively areas. Among the interviewed, the majority used vessels of the type ”canoa” and small-sized boats. In both areas, the gillnet is the most used. The net length ranged between 150-5000mm, height of 2,7m, mesh size 20-75mm and the immersion is, in average of 3,5h in both areas. Four species of small cetacean were recognized in the contemplated areas. All the interviewed affirmed that the boto (Inia geoffrensis) “disturbs” the fishery, taking the fish off the gillnet damaging the artifact. And they claim that the Guiana dolphin (Sotalia guianensis) helps the activity, pointing and/or surrounding the school. The interviewed reported the ocurrence of by catches in gillnets for S. guianensis and Inia geoffrensis, the fishermen refers to the strandings as consequences of the driftnets. The caught specimens accidentally are entirely discarded or taken, removing: eyeballs, teeth, and genital, that costumes are related to the Amazonic culture and its mysticisms. The use of dolphin fat were quoted with medical purposes and in reduced number some fishermen affirmed to have eaten meat, which is not a usual habit at the region. The use of carcasses as long-line bait were recorded and report to a more antique habit, when such practice wasmore intense, the informers report that the Guiana dolphin and the “tunina” (Tursiops truncatus, Stenno bredanensis), are harpooned and used as baits in the nearby towns. The continuity of the fishery arts survey and their impact on the dolphins at Amazon region must regard the particularity of each area, taking it as base to future actions aiming the conservations of small cetaceans.Acesso AbertoPescaCetáceoBoto - Mamífero aquáticoPará - EstadoCNPQ::CIENCIAS EXATAS E DA TERRA::OCEANOGRAFIATrabalho de Curso - Graduação - Monografia
