Resumo: 	The distribution and abundance of fish eggs and larvae was analyzed in three sections of the Upper Uruguay river, in a stretch of 290 km. Samples were collected monthly from October, 2001 to March, 2002 during 48-h cycles at 6-h intervals between each sampling. Surface and bottom samples were collected with a 0.5-mm mesh cylindroconical net. Fishes from the Upper Uruguay river were reproductively active mainly from October to January, and this activity was more intense at the Ligeiro and Chapecó tributaries and Chapecó main river. It was observed that the tributaries are important spawning grounds and larval nursery sites, indicating the importance of preserving such environments.
