Processed fish is known to have been systematically traded in Europe since the Early Middle Ages to meet increasing demand of incipient markets and religious precepts, yet specific details regarding the supply of different fish in Southern Europe is often missing. Here, we address this gap through an integrated approach involving bone metrics and stable isotopic analysis of archaeological European hake (Merluccius merluccius, Merluccidae) from the Iberian Peninsula. The results offer new insights regarding historical fisheries production systems, including the regions exploited and commercial routes, whilst also revealing biological differences between archaeological and present-day hake populations in the North-east Atlantic and the Mediterranean Sea. This research highlights the fruitful result of combining ichthyoarchaeological and historical data for tracking down the origin and development of historical fisheries in south-western Europe and their bearing on modern fisheries.

使用稳定同位素阐明伊比利亚半岛的历史渔业网络

众所周知，自中世纪早期以来，加工鱼品就在欧洲进行了系统性交易，以满足新兴市场和宗教戒律日益增长的需求，但有关南欧不同鱼类供应的具体细节往往缺失。在这里，我们通过一种综合方法解决了这一差距，该方法涉及骨骼指标和考古欧洲无须鳕 ( Merluccius merluccius ) 的稳定同位素分析, Merluccidae) 来自伊比利亚半岛。这些结果提供了关于历史渔业生产系统的新见解，包括开发的区域和商业路线，同时还揭示了东北大西洋和地中海的考古和当今无须鳕种群之间的生物学差异。这项研究突出了将鱼类考古和历史数据相结合，以追踪欧洲西南部历史渔业的起源和发展及其对现代渔业的影响的丰硕成果。
