“…It appeared that, in most cases, the BOPA and BO2A indices tended to overestimate the Ecological Status of the stations (e.g. Caglar and Albayrak, 2012;Reizopoulou et al, 2014;Aguado-Giménez et al, 2015), but the comparisons showed in most of the cited studies did not take into account the revised thresholds proposed by de-la-Ossa-Carretero and , including recent publications (Nebra et al, 2014;Aguado-Giménez et al, 2015). In addition, Keeley et al (2012) pointed out that the Ecological Status classification was underestimated by BOPA when the species richness and abundances of macro-invertebrates were very low, though the use of BOPA was not recommended for abundance <20 ind.…”

a b s t r a c tAmong the macro-invertebrates used for the assessment of soft-bottom communities, most polychaetes are classified as tolerant/opportunistic to pollution while amphipods are considered as sensitive. These taxa have been used in several ecological indices, such as the simple abundance ratio between Polychaeta and Amphipoda or the Benthic Opportunist Annelids Amphipods (BO2A) index, to assess the Ecological Quality Status -EcoQs-of soft-bottom communities. In terms of Taxonomic Sufficiency (TS), the polychaete/amphipod ratio (i.e. at the level of the class/order) has been proved to be effective in identifying major changes in benthic communities following disturbances. However, an underlying issue is to assess the acceptable TS limit value needed to state accurately the quality of the benthic environment. We tested three indices using 18 series of observations carried out in five north-eastern Atlantic and Mediterranean zones impacted by oil spills, oil and gas production, brine and urban sewage, harbours and aquaculture farms within impacted and control areas. Similar results to BO2A were obtained when limiting the TS at the level of Polychaete opportunistic families, which required a lower degree of taxonomic expertise, and classifying all amphipods as sensitive taxa. In such a way that the EcoQs given by the BPOFA (Benthic Polychaete Opportunistic Families Amphipods) was very similar to those given by the BO2A (Benthic Opportunistic Annelids Amphipods).

“…BENTIX is considered an ecologically relevant biological index, which is easier to operate than AMBI and M-AMBI and has been successfully applied to areas of organic matter pollution, oil spills, and heavy metal pollution (Simboura and Zenetos, 2002;Zenetos et al, 2004;Simboura et al, 2007). It is more sensitive to the increase in organic matter content in sediments than AMBI (Caglar and Albayrak, 2012), but all opportunistic taxonomic groups (AMBI-EG IV and V) and sensitive taxonomic groups (AMBI-EG III) are given the same proportion in the evaluation; therefore, the ecological state is easily underestimated. At the same time, unassigned organisms remain neglected because of their reliance on the AMBI classification criteria.…”

Semi-enclosed bays have physical and chemical characteristics influenced by both land and sea systems and the quality of the benthic environment is always of great concern. Macrofauna are considered good indicators for evaluating the benthic ecological quality status owing to their biological characteristics. In this study, six biotic indices, namely the Shannon–Wiener diversity index (H′), Abundance-Biomass Comparison (ABC) curve, AZTI’s Marine Biotic Index (AMBI), multivariate-AMBI (M-AMBI), BOPA index, and BENTIX index, were used to evaluate the adaptability of different biological indices in the bioassessment of the benthic environment in a semi-enclosed bay. In the annual environmental assessment of the study area, the average values of the six indices (H′, ABC curve, AMBI, M-AMBI, BOPA, and BENTIX) were 4.494, 0.182, 2.433, 0.791, 0.033, and 3.813, respectively; accordingly, H′, M-AMBI, and BOPA met the high standards whereas the other indices met the good standards, indicating that the whole study bay was slightly disturbed and had good ecological quality. From the perspective of spatial variation, the benthic environment in the middle of the bay was better than that in the north; the environmental problems in the northeast were particularly noteworthy. In terms of temporal patterns, the benthic environment in winter and summer was significantly better than that in spring and autumn, with obvious seasonal differences. The present results indicate that the H′ and ABC curve based on benthic abundance and biomass should be avoided for environmental assessment in mariculture areas. AMBI and M-AMBI should be used with caution when the percentage of unassigned species is high, in which case H′ is the appropriate choice. When there are few unassigned species, M-AMBI is more conducive for accurate evaluation of the benthic environment than AMBI and H′.

“…Benthic indices have been extensively applied to assess the ecological quality of coastal regions worldwide, effectively gauging the impact of human activities on coastal ecosystem quality in numerous investigations [7]. For example, the multivariate AMBI (M-AMBI) is an effective index for assessing the ecological quality of the Sea of Japan [8], and the BENTIX is an effective index for assessing the ecological quality of the Marmara Sea [9]. Indices based on macrobenthos are commonly employed to evaluate the ecological quality of coastal areas globally.…”

With the rapid development of the South Korean economy, human activities have extensively affected Korea’s coastal environment. A precise ecological quality assessment remains paramount despite the relatively lower impact of human activities on the East Sea compared to the West and South Seas of South Korea. Accurate ecological quality assessments can provide valuable marine environmental protection and management references. In our study, we employed seven indices based on heavy metals and macrobenthos to comprehensively assess ecological quality. Our results indicated the final ecological quality in the central East Sea of South Korea was acceptable at most stations; however, the ecological quality in winter marginally falls short compared to that in spring. The concentration of heavy metals emerges as a significant determinant of the final ecological quality, underscoring the need for subsequent studies to investigate the origins of heavy metals in the central East Sea of South Korea and the influence of anthropogenic activities on heavy metal concentrations. Furthermore, employing a single biotic index proves challenging for accurately assessing ecological quality in the East Sea of South Korea.
