Ethnozoology of Sotalia fluviatilis (Cetacea, Delphinidae), in the north channel of the Amazon River, Amapá – Brazil

Abstract

Tucuxi, Sotalia fluviatilis is one of the species of river dolphins that occur in the Amazon basin. The species is insufficiently known by science, and completely lacking information for the state of Amapá. Given this fact, the work aims to verify the level of traditional knowledge of the local riverside community about the tucuxi boto, S. fluviatilis of the northern channel of the Amazon River, Amapá. Interviews took place with the resident population in the vicinity of the study area with the application of an interview form. Most of the interviewees frequently observed individuals from S. fluviatilis mainly in small groups, also stating that the tucuxi boto was much more frequent in the past. The displacement, jumping and feeding behaviors were the most reported. Thus, studies that support contemplating initiatives about the knowledge of key species, are essential for taking measures, aiming to optimize conservation strategies for this aquatic mammal in the State of Amapá.
