Due to its high productivity and easy cultivation, B. sowerbyi is of great interest as a food source for fish farming. The present study reports information on the reproductive biology and growth of B. sowerbyi under laboratory conditions at 25 ± 1ºC. Weekly observations during 52 weeks indicated that the time between cocoon laying and young hatching was 14 to 16 days, the specific daily growth rate was 0.91 ± 0.04% (mean ± SD) and the time to reach sexual maturity was 40.83 ± 6.88 days. As reported by other authors, the hatching rate observed was low (33.08%), but the survival rate of young was high, approximately 96%. Laboratory observations showed that B. sowerbyi has two annual reproductive cycles, the first (between the 5th and 24th week) being more pronounced than the second (between the 31st and 51st week) concerning the number of cocoons.eng--BrasilZoologia (Curitiba)-CocoonsFish foodGrowth rateOligochaeteTubificidReproductive cycle of Branchiura sowerbyi (Oligochaeta: Naididae: Tubificinae) cultivated under laboratory conditionsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleLobo, HaroldoAlves, Roberto da Gamainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFJFinstname:Universidade Federal de Juiz de Fora (UFJF)instacron:UFJFTHUMBNAILReproductive cycle of Branchiura sowerbyi.pdf.jpgReproductive cycle of Branchiura sowerbyi.pdf.jpgGenerated Thumbnailimage/jpeg1575https://repositorio.ufjf.br/jspui/bitstream/ufjf/8405/4/Reproductive%20cycle%20of%20Branchiura%20sowerbyi.pdf.jpgfc435770c3c71669e9b8b48f56edae3aMD54ORIGINALReproductive cycle of Branchiura sowerbyi.pdfReproductive cycle of Branchiura sowerbyi.pdfapplication/pdf475594https://repositorio.ufjf.br/jspui/bitstream/ufjf/8405/1/Reproductive%20cycle%20of%20Branchiura%20sowerbyi.pdff932bcbe35463bbcaa1b577d9d73b964MD51LICENSElicense.txtlicense.txttext/plain; charset=utf-82197https://repositorio.ufjf.br/jspui/bitstream/ufjf/8405/2/license.txt000e18a5aee6ca21bb5811ddf55fc37bMD52TEXTReproductive cycle of Branchiura sowerbyi.pdf.txtReproductive cycle of Branchiura sowerbyi.pdf.txtExtracted texttext/plain22848https://repositorio.ufjf.br/jspui/bitstream/ufjf/8405/3/Reproductive%20cycle%20of%20Branchiura%20sowerbyi.pdf.txt610a4230b2949e28e14187ca087fb9e5MD53ufjf/84052019-06-16 09:23:54.41oai:hermes.cpd.ufjf.br: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Repositório InstitucionalPUBhttps://repositorio.ufjf.br/oai/requestopendoar:2019-06-16T12:23:54Repositório Institucional da UFJF - Universidade Federal de Juiz de Fora (UFJF)false
