XII (L): L0l - Ll8 Kiel, Juni 1992 AMAZONIANA XII (l): l0l - ll8 Kiel, Juni 1992 Food taboos and folk medicine among fishermen from the Tocantins River (Brazil) by Alpina Begossi- and Francisco Manoel de Souza Braga Dr. Alpina Begossi, Departamento de Ecologia, IB, Universidade Federal do Rio de Janeiro, C.P. 68020, 21941Rio de Janeiro, RI, Brazil. Prof. Dr. Francisco Manoel de Souza Braga, Departamento de Zoologia, Universidade Estadual Paulisø, C.P. 179, 13.500 Rio Claro, SP, Brazil. (Accepted for publicatian: August, 1990). Abstract Fish utilization for food and folk medicine, and fish preference of families from the Tocantins river were studied. Questionnaires werc used in the 234 interviews performed in cities, towns and scatteres houses located along 100 km of river stretch. Curimatí (Prochilodtu nigricans) is the most consumed fish and pacu-manteiga (Mylossorna duriventre) ¡he most preferred species. The fish species avoided are correlated with the species used in folk medicine (r, = 0,54, p < 0.02). Food t¡boos, orfish species not consumed during illness, are also cited. The usefulness of fish species for folk medicine and the piscivorous habits of most fish quoted as not consumed partially explain the food choices of fishermen. These explanations conform to materialist theories in cultural ecology. Keywords: DIeÇ food teboog ñshlng communitleq Brezll, Rlo Toc¡ntins. Introduction Food preferences and avoidances have been a subject of many studies in Anthro- pology and Human Ecology. MESSER (1984) reviewed some of these studies and factors involved in the fmd choice of human populations. The avoidances of some food by people are considered to be based on ideological criteria (SAHLINS 1976) or on materialist reasons (HARRIS L977,1985). The ideologi- cal view considers that cultural patterns are arbitrary and derive from the human mind (ROSS 1987). Thus, we need to understand the internal logic of culturally specific symbol systems (BASSO 1978). The materialist point of view considers tho costs and ' Present address: NEPAÌví/IJMCAMP, C. P.

For example, HARRIS (1985), based mainly on ecological and economical principles, explained why cor¡/s are avoided as food in India, why dogs are usually not eaten by Westerners and why insects are eaten and considered very østy by a variety of other human populations. A R,A As summarized by HARRIS (1987), food habits are explained by the idealist approach " /,/ as consequence of culture and by the materialist criæria by environmental, demographic, technological and political-economic factors. Food avoidances, or food taboos, have also been interpreted as a way of minimizing fhe overexploitation of certain animals G.OSS I MPERÂÎâ I Z r978). STATE This study focuses on fish preferences and avoidances of fisherman families on the 4æ V¡Rar.¡¡]ÃO Tocantins river, in Brazil. Our aim is to analyze fish utilization and understand why STATE some available fish are eaten where¿¡s others are rejected as food. In this study we use the terms "fish avoided" for species of fish which are usually not consumed and "fish a L^JË^OO taboos" for species of fish not consumed during illness. TOCANTIN9 Methodology STATE The study sites include cities, small towns and riverine settlements loc¡ted in the banks of the Tocantins river, between the cities of Imperatriz and Estreito. The extension of the area is abor¡t 100 km and it is located in the States of Mara¡rhão and Tocantins. Fieldwork included mainly interviews with fishermen and their wives, and was performed in altemate months from October 1987 to June 1988. The cities and towns studied at the Tocantins river are shown in figure l Imperatri", Porto Franco, Tocantinópolis and Estreito are considered. as "cities" and ltaguatins, Descarreto and lajeato.as "towns".

This probably occurs because women take care of children and prepare folk medicine at home. In the case of a fisherman's absence, the questionnaire was applied to his wife. The family was the unit 3. Fish feeding habits of study. Fish feeding habits werc observed through the analysis of stomach contents and through the literature. The "Colônias de pescadores" (fishermen's associatiurs) of Imperatriz and Estreito helped in estimating Unfortunately, there are cønparatively few studies on feeding habits of Br¿zilian fresh water fish.

The aim of this work is to increase the knowledge of the stream’s fish fauna in the State of Goiás, Brazil. 12 streams from the municipalities of Barro Alto and Niquelândia were sampled with trawl nets. During this study, 1247 fishes belonging to 27 species, 11 families, and three orders were collected. Characiformes comprised 1164 specimens of the sampled fishes, the most abundant order, while Perciformes was the less abundant order, with 17 collected specimens.

It supports countless thousands of species, as well as 30 million people. © Brent Stirton / Getty Images / WWF-UK © Brent Stirton / Getty Images The Amazon is the largest rainforest on Earth. It’s famed for its unrivalled biological diversity, with wildlife that includes jaguars, river dolphins, manatees, giant otters, capybaras, harpy eagles, anacondas and piranhas. The many unique habitats in this globally significant region conceal a wealth of hidden species, which scientists continue to discover at an incredible rate. Between 1999 and 2009, at least 1,200 new species of plants and vertebrates have been discovered in the Amazon biome (see page 6 for a map showing the extent of the region that this spans). The new species include 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals. In addition, thousands of new invertebrate species have been uncovered.

    THE RELEVANCE OF THE CERRADO’S WATER RESOURCES TO THE BRAZILIAN DEVELOPMENT Jorge Enoch Furquim Werneck Lima1; Euzebio Medrado da Silva1; Eduardo Cyrino Oliveira-Filho1; Eder de Souza Martins1; Adriana Reatto1; Vinicius Bof Bufon1 1 Embrapa Cerrados, BR 020, km 18, Planaltina, Federal District, Brazil, 70670-305. E-mail: jorge@cpac.embrapa.br; euzebio.medrado@gmail.com; cyrino@cpac.embrapa.br; eder@cpac.embrapa.br; reatto@cpac.embrapa.br; vinicius.bufon@cpac.embrapa.br ABSTRACT: The Cerrado (Brazilian savanna) is the second largest Brazilian biome (204 million hectares) and due to its location in the Brazilian Central Plateau it plays an important role in terms of water production and distribution throughout the country. Eight of the twelve Brazilian hydrographic regions receive water from this Biome. It contributes to more than 90% of the discharge of the São Francisco River, 50% of the Paraná River, and 70% of the Tocantins River. Therefore, the Cerrado is a strategic region for the national hydropower sector, being responsible for more than 50% of the Brazilian hydroelectricity production. Furthermore, it has an outstanding relevance in the national agricultural scenery. Despite of the relatively abundance of water in most of the region, water conflicts are beginning to arise in some areas. The objective of this paper is to discuss the economical and ecological relevance of the water resources of the Cerrado. Key-words: Brazilian savanna; water management; water conflicts. INTRODUCTION The Cerrado is the second largest Brazilian biome in extension, with about 204 million hectares, occupying 24% of the national territory approximately. Its largest portion is located within the Brazilian Central Plateau which consists of higher altitude areas in the central part of the country.
