This study reports length-weight relationships for Apareiodon affinis, Leporinus obtusidens, Cynopotamus argenteus, Loricariichthys melanocheilus, Parapimelodus valenciennis, Iheringichthys labrosus, Rhinodoras dorbignyi and Pachyurus bonariensis. Specimens were collected between 2006 and 2007 from the lower section of the Uruguay River. The study represents the first reference on weight-length relationships for three species and also provides the new maximum size for three species. © 2008 Blackwell Verlag, Berlin.
