The aim of this work is to present the results of a five years survey on gonadosomatic index as well as absolute and relative fecundity and morphological characteristics of developing oocytes of Leporinus obtusidens ("boga") from two areas of the Parana River, Argentina, one located in the proximity of Yaciretá dam and considered of great environmental impact, and the other far away from the dam (control). Results indicate that, despite the numerous environmental modifications due to the presence of the dam such as fluctuating water levels, negative impact was not observed over reproduction of L. obtusidens.
