Water pollution plus Bistrita River and crossing the river had a major negative impact on communities of aquatic organisms, particularly on fish communities. Sampling of biological material from sampling points and data processing have led to results on the overall environmental condition of the river Bistrita. Rich in species abundance and gives an indication of the specific degree of impairment of human impact aquatic ecosystems. By applying synthetic ecological indexes such as IBI and EFI +, put out both the level of damage in each sampling and classification of each river section in a given fishing zone.
