Resumo: | Despite the serious threats that affect shark species living along the central coast of Brazil, knowledge about the life history of these animals is still scarce. The present study describes the knowledge and perceptions of fishermen from southern Bahia, Brazil, on the trophic interactions of sharks. The objective of this work was to generate information that contributes to a better understanding of the life history of sharks from this poorly known region. In 2012, semi-structured interviews were conducted with 65 fishermen, with over 15 years of experience, about fisheries and aspects of shark feeding behavior. The study found that the participants have comprehensive ethno-ecological knowledge about shark feeding habits, describing 39 types of items as components of the diets of these animals. They are also able to recognize the favored items in the diet of each ethnospecies of shark. Similar studies about shark feeding habits along the Brazilian coast should be developed. This will generate more detailed knowledge and/or new scientific hypotheses about the interspecific relationships of these predators and their prey. |

Não obstante as graves ameaças que enfrentam as espécies de tubarões que habitam a Costa Central brasileira, os conhecimentos sobre a história de vida desses animais ainda são bastante escassos. O presente estudo descreve o conhecimento e percepções de pescadores do sul da Bahia, Brasil, sobre interações tróficas de tubarões. O objetivo deste trabalho foi gerar informações científicas que contribuam para um maior entendimento sobre a história de vida das espécies de tubarões existentes nessa pouco conhecida região. Em 2012, realizaram-se entrevistas semiestruturadas com 65 pescadores, com mais de 15 anos de experiência, sobre a pesca e aspectos da alimentação desses peixes. Os participantes detêm conhecimentos etnoecológicos detalhados sobre os comportamentos alimentares dos tubarões, além de terem apontado 39 tipos de itens como componentes da dieta desses animais. Reconhecem também as presas preferenciais de cada etnoespécie de tubarão. Sugere-se o desenvolvimento de pesquisas semelhantes sobre os tubarões ao longo da costa brasileira. Assim, será possível gerar conhecimentos mais detalhados e/ou novas hipóteses científicas sobre as relações interespecíficas desses predadores e também das suas presas.Universidade Federal de Santa Catarina2016-09-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2016v29n3p4110.5007/2175-7925.2016v29n3p41Biotemas; v. 29 n. 3 (2016); 41-522175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2016v29n3p41/32438Copyright (c) 2016 Márcio Luiz Vargas Barbosa- Filho, Eraldo Medeiros Costa-Netoinfo:eu-repo/semantics/openAccessBarbosa- Filho, Márcio Luiz VargasCosta-Neto, Eraldo Medeiros2017-10-18T18:35:08Zoai:periodicos.ufsc.br:article/41790Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-18T18:35:08Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
