Resumo: The objective of this study was to evaluate the influence of the photoperiod on the physiological, hematological and reproductive parameters of tilapia males of the GIFT lineage. The treatments differed in the simulations of emeral photoperiods T1 = 0L: 24E T2 = 24L: 0E, T3 = 12L: 12E. Each aquarium was considered an experimental unit. In the present study, tilapia males under different photoperiods did not present significant differences in gonad weight and gonadosomatic index. At the end of the experiment, there were also no significant differences in hepatosomatic indexes (IHS) of Tilapia males under different treatments. In the present experiment, it was observed that the 0L: 24E treatment obtained a shorter testicular length in relation to the other treatments. In addition, the Tilapia submitted to 24L: 0E presented significant difference for the glucose levels, and did not present significant difference for cortisol levels and survival rate compared withthe other treatments. There were no statistical differences for hematological values. Exposure to different light regimes has shown that for GIFT tilapia, the photoperiod that promotes better reproductive index and well-being conditions is the photoperiod (12L: 12E).

Os tratamentos diferiram nas simulações dos fotoperíodos emeral T1 = 0L: 24E T2 = 24L: 0E, T3 = 12L: 12E. Cada aquário foi considerado uma unidade experimental. No presente estudo, os machos de tilápia sob diferentes fotoperíodos não apresentaram diferenças significativas no peso gonadal e no índice gonadossomático. Ao final do experimento, também não houve diferenças significativas nos índices hepatossomáticos (IHS) dos machos de tilápias sob diferentes tratamentos. No presente experimento, observou-se que o tratamento 0L: 24E obteve menor comprimento testicular em relação aos demais tratamentos. Além disso, a tilápia submetida a 24L: 0E apresentou diferença significativa para os níveis de glicose, e não apresentou diferença significativa para os níveis de cortisol e sobrevivência em comparação com os demais tratamentos. Não houve diferenças estatísticas para valores hematológicos. A exposição a diferentes regimes de luz mostrou que, para a tilápia GIFT, o fotoperíodo que promove melhor índice reprodutivo e condições de bem-estar é o fotoperíodo (12L: 12E).EDUFU2019-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4184410.14393/BJ-v35n6a2019-41844Bioscience Journal ; Vol. 35 No. 6 (2019): Nov./Dec.; 1915-1922Bioscience Journal ; v. 35 n. 6 (2019): Nov./Dec.; 1915-19221981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/41844/27478Brazil; ContemporaryCopyright (c) 2019 Yvonaldo wladimir saldanha Bizarro, Rodrigo Diana Navarro, Oswaldo Pinto Ribeiro Filho, Fernanda Keley Silva Pereira Navarro, Rodrigo Diana Navarrohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBizarro, Yvonaldo wladimir saldanhaNavarro, Rodrigo DianaRibeiro Filho, Oswaldo PintoNavarro, Fernanda Keley Silva PereiraNavarro, Rodrigo Diana2022-01-25T22:03:05Zoai:ojs.www.seer.ufu.br:article/41844Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-25T22:03:05Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
