We assayed fatty acids in the flesh of Arctic cisco (adult and juvenile), least cisco , muksun , and Arctic charr inhabiting water bodies of the Gydan Peninsula, Siberia, Russia. The highest concentrations of total and polyunsaturated fatty acids (PUFAs) were found in Arctic charr (27.8 and 9.5 mg g) and adult Arctic cisco (20.2 and 7.6 mg g), while the lowest concentrations occurred in juvenile Arctic cisco (7.5 and 3.6 mg g). Multivariate analyses divided all studied fish into five distinct groups with the highest similarity between least cisco and muksun and the highest dissimilarity between juvenile Arctic cisco and Arctic charr. Coregonid fish from the study area had a higher content of docosahexaenoic and eicosapentaenoic acids than their conspecifics from subarctic and temperate habitats. The flesh of the studied fish is a source of a healthy diet for humans. Taking into account that all the studied fish are components of the traditional diet of indigenous peoples in northwestern Siberia, our data may be useful not only for local consumers and anglers but also for stakeholders focused on food policy and food security in the area.
我们分析了栖息在俄罗斯西伯利亚吉丹半岛水体中的北极白鲑（成鱼和幼鱼）、小体白鲑、穆森白鲑和北极红点鲑鱼肉中的脂肪酸。在北极红点鲑（27.8和9.5毫克/克）和成体北极白鲑（20.2和7.6毫克/克）中发现了最高浓度的总脂肪酸和多不饱和脂肪酸（PUFA），而在幼体北极白鲑中浓度最低（7.5和3.6毫克/克）。多变量分析将所有研究的鱼类分为五个不同的组，小体白鲑和穆森白鲑之间的相似度最高，幼体北极白鲑和北极红点鲑之间的差异最大。研究区域的白鲑科鱼类中二十二碳六烯酸和二十碳五烯酸的含量高于来自亚北极和温带栖息地的同种鱼类。所研究鱼类的鱼肉是人类健康饮食的一个来源。考虑到所有研究的鱼类都是西伯利亚西北部土著人民传统饮食的组成部分，我们的数据不仅可能对当地消费者和垂钓者有用，而且对关注该地区粮食政策和粮食安全的利益相关者也有用。
