Resumo: This paper aims at studying the influence of photoperiod on the cultivation of Brycon orbignyanus (Valenciennes, 1849) (Osteichthyes, Characidae) post-larvae submitted to four treatments: 0L-24D (L=Light; D=Dark), 10 - L14D, 14L - 10D and 24L-0D, with 3 repetitions. Post-larvae measuring 7.8±0.7mm and weighting 3.5±0.8mg were distributed in 12 aquariums (10L), stocked with 12 post-larvae per aquarium. Fishes were fed daily with Artemia sp. nauplii, in 10 days experiment. A positive relationship between the survival rate (88.9±9.7%) observed in the treatment with 24 hours of luminosity, and the lowest (58.3±8.3%), in the treatment with 24 hours of darkness. No difference was showed (P>0.05) in the mean length and weight of the post-larvae, although there was greater heterogeneity among the post-larvae cultivated at the longer darkness period.

Pós-larvas com comprimento de 7,8±0,7mm e com peso de 3,5±0,8mg foram distribuídas em 12 aquários de 10L, estocados com 12 pós-larvas por aquário. Os indivíduos foram diariamente alimentados com naúplios de Artemia, ao longo dos 10 dias de experimento. Ao final, observou-se relação positiva entre a sobrevivência e o aumento do período com luz, sendo o maior valor de sobrevivência 88,9±9,7%, obtido no tratamento com 24 horas de luminosidade, e o menor valor 58,3±8,3%, no tratamento com 24 horas em escuridão. O comprimento e peso das pós-larvas de piracanjuba não apresentaram diferenças significativas (P>0,05) entre os diferentes tratamentos, porém foi observada uma maior heterogeneidade entre as pós-larvas cultivadas com maior período de escuridão.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/231710.4025/actascibiolsci.v24i0.2317Acta Scientiarum.
