通过手术植入或与卫星相连的电子数据存储标签的部署为海洋研究人员提供了新的方法来研究远洋脊椎动物的运动、环境偏好和生理。我们报告了使用植入式档案标签和弹出式卫星档案标签对大西洋蓝鳍金枪鱼进行标签的结果。电子标签数据提供了对该物种的季节性活动和环境偏好的洞察。蓝鳍金枪鱼下潜到1000米深处，并保持体温。标有西方标签的蓝鳍金枪鱼跨越大西洋迁徙，它们经常在墨西哥湾和地中海东部的产卵场活动。这些数据对未来大西洋蓝鳍金枪鱼的管理和保护至关重要。
The deployment of electronic data storage tags that are surgically implanted or satellite-linked provides marine researchers with new ways to examine the movements, environmental preferences, and physiology of pelagic vertebrates. We report the results obtained from tagging of Atlantic bluefin tuna with implantable archival and pop-up satellite archival tags. The electronic tagging data provide insights into the seasonal movements and environmental preferences of this species. Bluefin tuna dive to depths of >1000 meters and maintain a warm body temperature. Western-tagged bluefin tuna make trans-Atlantic migrations and they frequent spawning grounds in the Gulf of Mexico and eastern Mediterranean. These data are critical for the future management and conservation of bluefin tuna in the Atlantic.
