Delle Chiaje, 1841 (Annelida, Onuphidae) is one of the most exploited polychaete species in European waters, particularly in Ria de Aveiro, a coastal lagoon in mainland Portugal, where the overexploitation of this resource has led to a generalized decline of local populations. In an attempt to reduce the impact of harvesting, several management actions were implemented, but illegal poaching still fuels a parallel economy that threatens the sustainable use of this marine resource. The present study evaluated the combination of fatty acid profiles and elemental fingerprints of the whole body and jaws, respectively, of collected from four harvesting locations within Ria de Aveiro in order to determine if their geographic origin could be correctly assigned post-harvesting. Results showed that both fatty acid profiles and elemental fingerprints differ significantly among locations, discriminating the geographic origin with higher accuracy when combining these two natural barcodes than when employing each individually. The present work can, therefore, contribute to the implementation of an effective management plan for the sustainable use of this marine resource, making it possible to detect if was sourced from no-take zones and if it was collected from the place of origin claimed by live bait traders.
德拉·基亚耶，1841年（环节动物门，欧努菲科）是欧洲海域中被过度捕捞的多毛类物种之一，尤其是在葡萄牙大陆沿海泻湖阿威罗里亚，对该资源的过度开发导致当地种群普遍减少。为了减少捕捞的影响，实施了多项管理措施，但非法偷猎仍助长了一种并行经济，威胁到这种海洋资源的可持续利用。本研究分别评估了从阿威罗里亚四个捕捞地点采集的样本的全身和颚部的脂肪酸谱和元素指纹图谱的组合，以确定收获后能否正确确定其地理来源。结果表明，不同地点的脂肪酸谱和元素指纹图谱存在显著差异，将这两种天然条形码结合使用时，比单独使用每种条形码时能更准确地辨别地理来源。因此，本研究可为实施该海洋资源可持续利用的有效管理计划做出贡献，从而能够检测样本是否来自禁捕区，以及是否是从活饵交易商声称的原产地采集的。
