  Article:   MONITORING THE ECOLOGICAL STATUS OF RUNNING WATERS BASED ON FISH COMMUNITIES.

Authors:  KLAUS W. BATTES. 		 
       
         
  Abstract:   The present paper represents a review of the most common methods used in assessing water quality of running waters based on fish communities. Monitoring the ichthyofauna offers valuable information on the ecological status of aquatic ecosystems, because most of the times changes occurring in fishes reflect the changes from lower trophic levels, caused by human impacts but also by natural ecological factors. The newest trends in fish-based methods for assessing European running waters are presented, including the Index of Biological Integrity and the European Fish Index.
