The aim of this paper was to test how benthic fauna and biogeochemical properties of sediment will vary in response to similar levels of organic enrichment (induced by fish farming) as a function of bottom-habitat type (i.e., mud versus seagrass/coarse sediments), distance from the enrichment source and depth. Our results showed that samples from silty sediments in the vicinity of fish farms have higher TOC and TON values, higher oxygen consumption, higher PO(4) release and lower benthic diversity. In this context muddy sites are more likely to be identified as impacted/critical, than coarse sediment ones.
本文旨在研究底栖动物和沉积物的生物地球化学特性在类似的有机物富化（由水产养殖引起）水平下会如何变化，这种变化受到底栖生境类型（即泥质和海草/粗沉积物）、富化源距离和水深的影响。研究结果表明，养殖场附近粉砂沉积物中的样本具有更高的 TOC 和 TON 值、更高的耗氧量、更高的 PO(4)释放量和更低的底栖生物多样性。在这种情况下，泥质沉积物比粗沉积物更容易被识别为受影响/临界区域。
