Abstract

The ethnoichthyology aims to describe and enhance the knowledge of fisherfolk, through studies that prove that they are carriers of bio-ecological knowledge about the fish they catch. Thus, this study aimed to evaluate the ethnotaxonomy and food taboos of fisherfolk public weirs Araras and Edson Queiroz (Ceará, Brazil). Was selected a representative population of fishermen for each of these weirs: Ilha de Esaú, for the Araras reservoir, and Vila São Cosme, to Edson Queiroz reservoir. They were conducted participant observation, semi-structured interviews, visual stimulation and guided tours with fishermen in selected populations. Twenty fishermen interviewed in Vila São Cosme and twenty-four in Ilha de Esaú addressing socioeconomic aspects of fisheries and ethnoecological of the main species of fish. Twenty ethnospecies were cited of fish and shrimp to be caught in weirs. In the classification of fish populations, fishermen using morphological and ecological aspects, presenting several ethnospecies with generic and few names binomial names. In your diet, these people consume fish as the main source of animal protein, and there are restrictions on social and cultural character. Thus, the consistency of knowledge of the fishermen of the Ilha de Esaú and Vila São Cosme, this knowledge can be incorporated in the development of management plans and sustainable management of water and fishing resources of weirs Araras and Edson Queiroz.
