Fish farming is an important source of organic matter input in coastal waters, which contributes to eutrophication. In this study, the macrofaunal benthic community was studied after the cessation of fish farming with the aim of improving our understanding of benthic succession and sediment recovery in a marine ecosystem. The results showed that the best environmental variables for assessing organic pollution were acid-volatile sulfides (AVS) and redox potential. Succession and recovery was best explained by macrofaunal analysis based on community composition as well as on trophic groups. The patterns of recovery differed between each impacted station. For this reason, succession could not be accurately predicted due to the unique environmental parameters and the singular community functional structure of each location. The Azti Marine Benthic Index (AMBI) proved its validity for assessing pollution but did not distinguish between successional stages.
养鱼业是沿海水域有机物质输入的一个重要来源，这会导致富营养化。在本研究中，为了增进我们对海洋生态系统中底栖生物演替和沉积物恢复的理解，在养鱼业停止后对大型底栖动物群落进行了研究。结果表明，用于评估有机污染的最佳环境变量是酸挥发性硫化物（AVS）和氧化还原电位。基于群落组成以及营养类群的大型底栖动物分析能够最好地解释演替和恢复情况。每个受影响站点的恢复模式各不相同。因此，由于每个地点独特的环境参数和单一的群落功能结构，无法准确预测演替情况。阿兹蒂海洋底栖生物指数（AMBI）证明了其在评估污染方面的有效性，但无法区分演替阶段。
