本文探讨了稳定同位素分析的潜力，以确定捕捞鳕鱼的大致区域，通过分析骨骼从中世纪定居点在北方和西欧。它测量了从挪威北极、北海、卡特加特海峡和波罗的海周围收集的中世纪对照样本中鳕鱼骨胶原蛋白的C-13和N-15值。据认为，这些数据可能因区域而异，例如，由于食物链长度、水温和盐度的差异。我们发现，地理结构确实很明显，这使得我们有可能从遥远的沃茨捕获的鳕鱼中识别出骨骼。这些结果提供了一个新的方法来研究增长的干鳕鱼和相关的扩大捕捞努力的重要方面的发展，在中世纪的欧洲商业化。作为该方法的第一次测试，我们分析了鳕鱼骨暂定为进口干鱼先验动物考古学标准的基础上收集。研究结果初步表明，自公元第一个千年结束以来，鳕鱼被运输或交易的距离非常长。(C)2007爱思唯尔有限公司保留所有权利。
This paper explores the potential of stable isotope analysis to identify the approximate region of catch of cod by analysing bones from medieval settlements in northern and western Europe. It measures the delta C-13 and delta N-15 values of cod bone collagen from medieval control samples collected from sites around Arctic Norway, the North Sea, the Kattegat and the Baltic Sea. These data were considered likely to differ by region due to, for example, variation in the length of the food chain, water temperature and salinity. We find that geographical structuring is indeed evident, making it possible to identify bones from cod caught in distant waters. These results provide a new methodology for studying the growth of long-range trade in dried cod and the related expansion of fishing effort-important aspects of the development of commercialisation in medieval Europe. As a first test of the method, we analyse three collections of cod bones tentatively interpreted as imported dried fish based on a priori zooarchaeological criteria. The results tentatively suggest that cod were being transported or traded over very long distances since the end of the first millennium AD. (C) 2007 Elsevier Ltd. All rights reserved.
