Abstract:

In order to assess the general ecolological

status of river bodies, both the Index of Biological

Integrity (IBI) and the European Fish Index

(EFI+) can be successfully employed with similar

results. These indices prove that Moldova River

and its tributaries have a good ecological status

and are not affected by anthropogenic activities.

For the fish zoning of watercourses, the

calculation of the Index of Biological Integrity

seems to provide more realistic results, due to the

fact that it considers the species structure of the

inchtyocoenoses, as well as their abundance and

dominance in the sampling stations.

Keywords:

ecological status, Index of Biological Integrity (IBI), European Fish Index EFI+.
