Benthic indicators are important tools for the classification of coastal and transitional water bodies. The aim of the work was to assess for the first time the Environmental Status (ES) of Slovenian transitional waters, comparing the following biotic indices: richness, Shannon-Weaver diversity, AMBI, M-AMBI, BENTIX and BITS indices. A total of 13 stations were sampled with a Van Veen grab, in three ecosystems in the northern Adriatic. Samples were sieved and sorted, invertebrates identified and counted. The anthropogenic impact was estimated with professional judgement. Richness and diversity showed a good response to anthropogenic pressure. Conversely, indices based on sensitivity/tolerance groups did not showed a clear distinction between more and less impacted ecosystems. In particular BENTIX underestimated the ES, while with BITS there was a overestimation. The best evaluation was obtained with M-AMBI, because even if based on a sensitivity/tolerance approach, it considered also the structural aspect of the community.
底栖生物指标是对沿海和过渡水域进行分类的重要工具。本研究的目的是首次评估斯洛文尼亚过渡水域的环境状况（ES），比较以下生物指标：丰富度、香农-威弗多样性、AMBI、M-AMBI、BENTIX 和 BITS 指数。在亚得里亚海北部的三个生态系统中，用 Van Veen 抓斗共采集了 13 个站位的样本。对样品进行过筛和分类，鉴定并计数无脊椎动物。采用专业判断评估人为影响。丰富度和多样性对人为压力有很好的响应。相反，基于敏感性/耐受性组的指数并没有在受影响较大和较小的生态系统之间做出明显区分。特别是 BENTIX 低估了 ES，而 BITS 则存在高估。M-AMBI 得到了最佳评估，因为即使它基于敏感性/耐受性方法，也考虑了群落的结构方面。
