RESUMO:

The present study was carried out in the Rio Branco Indigenous Land (TI), located in the south of the state of Rondônia in the municipalities of Alta Floresta d'Oeste, São Francisco do Guaporé and São Miguel do Guaporé. In the Rio Branco IT can be found individuals belonging to the Aikanã, Arikapú, Aruá, Djereomitxí, Kanoê, Makurap and Tupari peoples. The objective of the study is to characterize the traditional knowledge of the indigenous fishermen of the Rio Branco basin, identifying from this knowledge the diversity and ecological dynamics of the fish in the Rio Branco basin, as well as the techniques and locations of indigenous fishing activities. at TI Rio Branco. Visits were made to the villages to establish socialization, and visits to the fishing grounds to learn about the environment and the techniques used by the indigenous people. The survey was conducted with 35 indigenous fishermen from various villages and ethnicities, selected according to the indication of the residents themselves, using a semi-structured questionnaire. Of the survey participants 21 are villagers who are located on the banks of the White River and have access only by river transport, while 14 indigenous people are villagers with road access. It was found that 68.5% of the indigenous fish for over 20 years in the White River and 85.6% is over 25 years old. Indians cited 21 species as being the most fished, highlighting Pseudoplatystoma sp. (Pintado), cited 34 times, followed by Prochilodus nigricans (Curimba), Astronutus crassipinis (Cara-açu), Cichla sp. (Tucunaré) and Serrasalmus sp. (Piranha) as the most fished. Regarding migration, two flows are observed, the first, from September to November, related to reproduction and the second, between April and May, a period of ebb, when the water volume is decreasing. There is a decrease in fish availability in the White River basin, which is the main environmental impact reported by the Indians except Clossoma macropomum (tambaqui) and Serrasalmus sp (piranha) that had their populations increased, highlighting the emergence of Arapaima gigas (pirarucu). ). Indians fish less than 20 hours a week, catching approximately 20 pounds of fish every other day. The natives fish in the riverbed, in the bays, in the flooded fields or in the igapós, with lines, archery and reeds, usually near their homes. Seasonal and annual variations influenced by high water levels contribute to indigenous fisheries development in the Rio Branco basin, and according to seasonal changes, they also occur to changes in fish species as well as variation in fishing locations and forms. catching fish. Some of these species are more appreciated by the indigenous as the species Astronutus crassipinis, Pseudoplatystom sp and Cichla sp, however there are species that are more fished by food necessity such as Serrasalmus sp. and Prochilodus nigricans. Indigenous people are concerned about the decrease in fish availability and possible disappearance of some species in the region, besides showing knowledge about invasive species and possible consequences related to the imbalance of aquatic ecosystems. It is concluded that the indigenous know the ecological aspects of the local ichthyofauna, such as migratory, dispersive, reproductive, food processes and the composition of species of food interest. They demonstrate the environmental impacts that interfere with fish availability and practice traditional and subsistence fishing. Fishing is one of the most important extractive activities of the White River basin, being the main source of protein in the food of indigenous peoples, and contributing as part of the family and social dynamics through which parents teach cultural values that have followed in the next generations. . Thus, this information may cooperate with the promotion of future studies on fish biodiversity in the Rio Branco basin.
