Biotic indices based on benthic communities have become an important tool in the assessment and monitoring of marine pollution.

Synthesis biotic indices were much less effective to diagnose the benthic alterations associated with this organic enrichment.

However, a consistent bias in index scores suggests that a habitat-adjusted interpretation of biotic indices could be employed to improve measurement precision.

One such indicator, the AZTI Marine Biotic Index (AMBI), was designed to establish the ecological quality of European coasts.

The comparison of the three indices demonstrates that in the southern Baltic Sea the ecological quality (EcoQ) classification based on macrozoobenthic communities as indicator greatly depends on the biotic index chosen.

Benthic data were collected separately and benthic invertebrate summary indices, specifically Hilsenhoff's Biotic Index (HBI) and Richness, were determined.
