Health assessment of khuzestan coastal and creeks area using BOPA & BOPA-m indices
Ecological health is the most important component of the biological health. Macrobenthos invertebrate are the most important organisms in aquatic ecosystems that are used for determination of biological health. Benthic indices base bye data simplifying and shows a set of biological variable as a quantified variable that made the interpretation of data easier, one of this indices is BOPA index that give from ratio of opportunistic Polychaeta to Amphipoda. The higher value of this index shows environmental pollution. The value of BOPA index showed significant difference between stations(p<0.05). according to BOPA index the status of stations were showed: st B: Fair, st C: poor, st A & E: good and st F,G: excellent. Despite all of stations according to diversity, richness showed poor and bad ecological status, but the value of these indices was increased from inner areas of creeks to sea, and BOPA index was decreased., so BOPA index has assessed the ecological status better than diversity and richness indices and is more optimistic.
