Summary

In the present paper, the results of two macrozoobenthos analysis based indices (Saprobic Index and Extended Biotic Index) are used as biological indicators in the assessment of river water quality. The objective of the paper is to establish the extent to which the results of these methods are comparable. The results indicate that both indices are suitable for assessing the quality of river water in the Croatian hydrographic network. Major deviations were only detected in xenosaprobic waters, i.e. at the springs of the Krka River and Crna rijeka, where the values of the Extended Biotic Index indicated poorer water quality.
