Abstract
The study was carried out in 2007 in three of the Danube tributaries, namely Drincea, Balasan, and Desnatui. 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. In this respect, after a taxonomical analysis, an ecological analysis was made, using some of ecological indices as well as biodiversity indices. The fish communities of the Drincea, Balasan, and Desnatui rivers display a great richness in species, especially in Drincea River. The ecological analysis reveals well-balanced fish communities in all of the three tributaries.
