Abstract:
In artisanal fishing, the techniques used by a community reflect the characteristics of the natural environment, in particular the distribution and availability of resources, as well as local traditions and customs. However, economic development may result in the loss of these traditions. The present study documents the fishing techniques used by the communities on the Xingu River in the Brazilian state of Pará (Maribel, Altamira, Belo Monte, Vitória do Xingu, Vila Nova, Senador José Porfírio, Porto de Moz, and Gurupá). Interviews were used to investigate traditional local knowledge and the distribution of the different fishing methods within the study area. The local fishers described the use of 12 different types of net, 10 hook and line techniques, and eight kinds of spearfishing. Free diving and scuba diving are also used for the capture of ornamental fish.
