The study was carried out in 2007 in Vedea River catchment area, including three of its tributaries (Plapcea, Cotmeana. Teleorman), and one of Teleorman River tributary (Clanita). Our research aims to contribute to the knowledge update by analyzing the structure of the fish communities in this area, and also to assess the state of fish communities from the ecological point of view. Comparing the structure of fish communities in our study with that of a recent study in Vedea River catchment area we could highlight the main differences between the structures of fish communities in the two period.
