许多元素的同位素组成在陆地和海洋表面都以一种可预测的方式变化。这些稳定同位素比例被转移到动物组织中，潜在地提供了一个强大的自然地理空间标签。到目前为止，在海洋环境中使用稳定同位素作为地理定位器的大多数研究都集中在哺乳动物和海鸟进行大规模的海洋盆地迁徙上。然而，对海洋环境中同位素变化的日益了解，以及采样和分析技术的改进，意味着稳定同位素现在作为海洋鱼类的自然地理位置标签具有真正的前景。本文综述了在海洋环境中使用耳石、鳞片和肌肉组织中稳定的碳、氮和氧同位素作为地理定位工具的理论背景，并提供了它们的应用实例。
The isotopic composition of many elements varies across both land and ocean surfaces in a predictable fashion. These stable-isotope ratios are transferred into animal tissues, potentially providing a powerful natural geospatial tag. To date, most studies using stable isotopes as geolocators in marine settings have focussed on mammals and seabirds conducting large ocean-basin scale migrations. An increasing understanding of isotopic variation in the marine environment, and improved sampling and analytical techniques, however, means that stable isotopes now hold genuine promise as a natural geolocation tag in marine fishes. Here, the theoretical background underpinning the use of stable isotopes of C, N and O in otolith, scale and muscle tissues as geolocation tools in the marine environment is reviewed, and examples of their applications are provided.
