通过分析整个全新世黎凡特南部考古遗址中gilhead seabream （Sparus aurata）牙齿珐琅样的磷酸盐氧同位素（δ18OPO4），研究了过去鱼类的来源、开发和贸易模式。我们报告了在埃及北西奈海岸的高盐Bardawil泻湖进行大规模鱼类开采的最早证据，这表明δ18OPO4值明显高，至少从青铜时代晚期（3,550-3,200 BP）开始，在黎凡特南部沿海和内陆地区变得丰富。冰期后的全球海平面稳定时期引发了巴达威尔泻湖的形成，该泻湖被大量开采，并支持了广泛的鱼类贸易。这代表了全新世晚期地中海沿海地区最早的海洋原始水产养殖根源。我们展示了对鱼牙齿进行大规模δ18OPO4分析的潜力，可以揭示古代的文化现象，为过去的贸易模式提供前所未有的见解。
Past fish provenance, exploitation and trade patterns were studied by analyzing phosphate oxygen isotope compositions (δ18OPO4) of gilthead seabream (Sparus aurata) tooth enameloid from archaeological sites across the southern Levant, spanning the entire Holocene. We report the earliest evidence for extensive fish exploitation from the hypersaline Bardawil lagoon on Egypt’s northern Sinai coast, as indicated by distinctively high δ18OPO4 values, which became abundant in the southern Levant, both along the coast and further inland, at least from the Late Bronze Age (3,550–3,200 BP). A period of global, postglacial sea-level stabilization triggered the formation of the Bardawil lagoon, which was intensively exploited and supported a widespread fish trade. This represents the earliest roots of marine proto-aquaculture in Late Holocene coastal domains of the Mediterranean. We demonstrate the potential of large-scale δ18OPO4 analysis of fish teeth to reveal cultural phenomena in antiquity, providing unprecedented insights into past trade patterns.
