Results from an acoustic telemetry study revealed for the first time a northerly migration route for Atlantic salmon (Salmo salar L.) smolts leaving the east coast of Ireland. Atlantic salmon smolts were tagged in spring 2019 in the Castletown and Boyne rivers. Three tagged smolts registered on disparate deep‐water offshore marine receivers as they travelled northwards out of the Irish Sea through the North Channel. One fish had migrated an estimated 250 km in a period of 32 days. The remaining two individuals were detected on receivers located off the Northern Ireland coast, further corroborating the northward migration of salmon smolts through the Irish Sea.

爱尔兰海中的大西洋鲑鱼熏鲑：北移轨迹的第一个证据

声学遥测研究的结果首次揭示了大西洋鲑（Salmo salar L.）迁徙到爱尔兰东海岸的北迁路线。大西洋鲑鱼在2019年春季在卡​​斯尔敦河和博恩河上进行了标记。当三只带标签的软体动物通过北海道向北离开爱尔兰海时，它们在不同的深海近海接收器上登记。在32天的时间里，一条鱼大约迁移了250公里。在北爱尔兰海岸附近的接收器上发现了其余两个人，进一步证实了鲑鱼向北迁移通过爱尔兰海。
