Resumo: The aim of this study was to investigate the influence of gonadal and nutritional index on reproductive behavior of Prochilodus cearensis (Steindachner, 1911) (Characiformes, Prochilodontidae) in Itans water reservoir, Caicó, Rio Grande do Norte. 213 animals were used (160 females and 53 males) and collected from Itans water reservoir during the period from April 1996 to January 1997. The highest Gonadossomatic and Gonadal Index values were obtained for females and males from December to February. The repletion index was similar for males and females. The condition factor (ø) showed the highest value just before reproduction. Data collected suggest that reproductive cycle in this species is not directly related to abiotic factors

As médias dos valores dos índices gônadossomático e gonadal apresentaram-se mais elevadas para fêmeas e machos no mês de janeiro. O índice de repleção foi semelhante entre os sexos. O fator de condição (ø) mostrou-se mais elevado no período que antecede à reprodução. Não foi observada correlação significativa entre os fatores abióticos e o ciclo reprodutivo da espécie. No entanto, a presença de indivíduos com gônadas preparadas para a reprodução no trimestre que antecede ao das chuvas sugere que a desova possa estar condicionada a sua ocorrênciaUniversidade Estadual De Maringá2008-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/202710.4025/actascibiolsci.v25i2.2027Acta Scientiarum.
