Resumo: The aim of this study was to evaluate the reproductive strategy of Aequidens tetramerus in small streams of the Machado river basin, southwestern Amazon. We collected samples in two streams using seine and dip nets along a 50-m stretch of the stream. We collected 86 fishes, 19 males and 67 females (sex-ratio, 3.52 female:1male). Their body size varied from 1.5 to 11.5 cm. The size at first reproduction was 1.8 cm for females and 2.0 cm for males. The reproductive season of the species occurred in the dry period.

As amostras foram coletadas em dois igarapés, utilizando rede de cerco e redes de mão ao longo de um trecho de 50 m do igarapé. Foram coletados 86 indivíduos, sendo 19 machos e 67 fêmeas (proporção-sexual, 3,52 fêmea:1macho). O tamanho dos indivíduos variou de 1,5 a 11,5 cm. O tamanho da primeira reprodução para fêmeas foi de 1,8 cm e dos machos 2,0 cm. A estação reprodutiva da espécie ocorreu no período seco.Universidade Federal de Santa Catarina2019-06-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n2p11510.5007/2175-7925.2019v32n2p115Biotemas; v. 32 n. 2 (2019); 115-1212175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n2p115/40112Copyright (c) 2019 Igor David Costa, Missilene Silva de Almeida Fachetti, Natalia Nunesinfo:eu-repo/semantics/openAccessCosta, Igor DavidFachetti, Missilene Silva de AlmeidaNunes, Natalia Neto dos Santos2019-06-03T18:41:22Zoai:periodicos.ufsc.br:article/58898Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-06-03T18:41:22Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
