Resumo: The present study evaluated the effects of fish farm dams on spatial and temporal distribution of lambari Astyanax cf. bimaculatus in five headwater streams of the Machado River basin, Rondônia State, Brazil. The results show that fish farm dams are spatially separating wild lambari populations into upstream and downstream groups. Moreover, it was observed that the dry and rainy seasons influence the abundance and presence of A. cf. bimaculatus in these areas, while limnological parameters did not differ y in the streams. Additionally, it was shown that fish farm dams built in the headwater stream areas impede the migratory routes of A. bimaculatus, and also possibly the local movements of resident fish populations. Therefore, before the implementation of new farm dams using natural streams in the future, mitigation plans should include adequate access routes for fish to travel between upstream and downstream areas, in order to avoid adversely affecting their wild populations.Keywords: Fish farm dams; lambari fish; Madeira River; microbasins; population parameters.

Os resultados mostraram que estes empreendimentos separam espacialmente as populações desta espécie em regiões a montante e a jusante das represas. No entanto foi observado que o regime sazonal de estiagem e chuva na região também interfere na abundância e presença de A. cf. bimaculatus nessas áreas. Foi verificado também que os parâmetros limnológicos mensurados nas áreas a montante e jusante das pisciculturas não diferiram a ponto de inferir uma tendência na distribuição do lambari na área de estudo. Os resultados mostram que as pisciculturas de barragens construídas ao longo dos canais dos igarapés estudados interferem no fluxo migratório do lambari, assim para a manutenção das populações de A. cf. bimaculatus, as construções de futuras pisciculturas de barramentos usando igarapés devem ser avaliadas com mais critério levando em consideração estratégias de manejo que possam permitir o fluxo das comunidades desse peixe nas áreas de jusante e montante dos empreendimentos.Palavras-chave: Barragens de piscicultura, lambari, Rio Madeira, microbacias, parâmetros de populações.Universidade Federal do AmapáAlex Junior Vervloet BrazRebecca BrevesConcelho Nacional de Desenvolvimento Científico e TecnológicoUniversidade Federal de Rondônia, Departamento de Engenharia de PescaMereles, Marcos de AlmeidaPiñeyro, Jairo Ildefonso GuimarãesMarshall, Bruce GavinSousa, Raniere Garcez Costa2017-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/238010.18561/2179-5746/biotaamazonia.v7n2p11-14Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 7, n. 2 (2017); 4-72179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPenghttps://periodicos.unifap.br/index.php/biota/article/view/2380/v7n2p4-7.pdfFish farming dams; Lambari fish; Madeira River; Microbasins; Population parameterscronologicaRandômicaDireitos autorais 2017 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2017-07-26T23:41:23Zoai:ojs.pkp.sfu.ca:article/2380Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2017-07-26T23:41:23Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
