欧洲鳗鱼（Anguilla anguilla）从欧洲到马尾藻海进行约5000公里（km）的产卵迁移。幼虫被墨西哥湾流和北大西洋漂流带回欧洲沃茨。然而，产卵迁移的细节仍然未知，因为到目前为止，在大西洋跟踪鳗鱼还没有研究。卫星跟踪的最新进展使得能够调查大型海洋动物的迁移行为。然而，现有标签的尺寸已经排除了跟踪欧洲鳗鱼等较小动物的可能性。在这里，我们提出的信息，在产卵迁移的欧洲鳗鱼的游泳方向，深度和迁移行为，基于一个小型化的弹出卫星档案发射机。虽然标记实验未能揭示到马尾藻海的全部迁移，但数据覆盖了前1300公里，并提供了独特的见解。
European eels (Anguilla anguilla) undertake a ~5000-kilometer (km) spawning migration from Europe to the Sargasso Sea. The larvae are transported back to European waters by the Gulf Stream and North Atlantic Drift. However, details of the spawning migration remain unknown because tracking eels in the Atlantic Ocean has, so far, eluded study. Recent advances in satellite tracking enable investigation of migratory behavior of large ocean-dwelling animals. However, sizes of available tags have precluded tracking smaller animals like European eels. Here, we present information about the swimming direction, depth, and migratory behavior of European eels during spawning migration, based on a miniaturized pop-up satellite archival transmitter. Although the tagging experiment fell short of revealing the full migration to the Sargasso Sea, the data covered the first 1300 km and provided unique insights.
