Fisher Ethnotaxonomy for Elasmobranchs Captured Along the Brazilian Amazon Coast

The diversity of popular names used in fish nomenclature off the Brazilian coast makes it difficult to identify species, and many have their origins Indigenous languages, mainly Tupi-Guarani. This study sought understand update list most assess some ethnotaxonomic patterns employed by artisanal fishers from Amazon Coast naming elasmobranchs. Interviews with 314 fishermen 17 coastal municipalities were carried out employing a semi-structured form, banners, photographic records local elasmobranch addressing characteristics applied species identification. A total 130 ethnospecies identified (113 Portuguese Tupi-Guarani origin) for identification 22 18 sharks rays, respectively. highest degree homonyms occurs interspecifically Dasyatidae, Mobulidae, Pristidae, Urotrygonidae, Carcharhinidae, Sphyrnidae Triakidae families. Sphyrna tiburo Hypanus guttatus comprised taxa common names. Morphological such as shape, colors, texture, size certain body parts are shark ray We conclude that use elasmofauna facilitates communication between scientific approach this ecological knowledge is fundamental management sustainability fisheries long term.
