Understanding large‐scale migratory behaviours, local movement patterns and population connectivity are critical to determining the natural processes and anthropogenic stressors that influence population dynamics and for developing effective conservation plans. Atlantic tarpon occur over a broad geographic range in the Atlantic Ocean where they support valuable subsistence, commercial and recreational fisheries. From 2001 through 2018, we deployed 292 satellite telemetry tags on Atlantic tarpon in coastal waters off three continents to document: (a) seasonal migrations and regional population connectivity; (b) freshwater and estuarine habitat utilization; (c) spawning locations; and (d) shark predation across the south‐eastern United States, Gulf of Mexico and northern Caribbean Sea. These results showed that some mature tarpon make long seasonal migrations over thousands of kilometres crossing state and national jurisdictional borders. Others showed more local movements and habitat use. The tag data also revealed potential spawning locations consistent with those inferred in other studies from observations of early life stage tarpon leptocephalus larvae. Our analyses indicated that shark predation mortality on released tarpon is higher than previously estimated, especially at ocean passes, river mouths and inlets to bays. To date, there has been no formal stock assessment of Atlantic tarpon, and regional fishery management plans do not exist. Our findings will provide critical input to these important efforts and assist the multinational community in the development of a stock‐wide management information system to support informed decision‐making for sustaining Atlantic tarpon fisheries.

二十年的卫星标记揭示了大西洋的迁移和运动

了解大规模的迁徙行为，当地的迁徙方式和人口连通性对于确定影响人口动态的自然过程和人为压力源以及制定有效的保护计划至关重要。大西洋发生在大西洋的广泛地理区域，在那里它们支持宝贵的生计，商业和休闲渔业。从2001年到2018年，我们在三大洲沿海水域的大西洋海带上部署了292个卫星遥测标签，以记录：（a）季节性迁徙和区域人口连通性；（b）淡水和河口栖息地的利用；（c）产卵地点；（d）在美国东南部，墨西哥湾和北加勒比海的鲨鱼捕食活动。这些结果表明，一些成熟的在跨越州和国家管辖边界的数千公里内进行了长期的季节性迁徙。其他人则表现出更多的当地活动和栖息地利用。标签数据还揭示了潜在的产卵位置，该位置与其他研究从生命早期的鱼小脑幼虫的观察中推断出的位置一致。我们的分析表明，释放的棉上的鲨鱼捕食死亡率高于先前的估计，尤其是在远洋通道，河口和海湾入口处。迄今为止，还没有对大西洋的正式种群评估，并且不存在区域渔业管理计划。
