More Pacific bluefin migrate across the ocean than previously recognized High market values have incentivized extensive fisheries for Pacific bluefin tuna (Thunnus orientalis, see the photo), a species whose longevity, commercial value, and long generation time make it particularly susceptible to overfishing (1, 2). Today, the population of Pacific bluefin tuna stands at an estimated 2.6% of prefished levels (1). Yet, knowledge of its basic life history is incomplete. Recent studies (3, 4) suggest that the fundamental distribution of Pacific bluefin across the North Pacific has been misunderstood. The results underscore the need for basic movement ecology information to assist science-based fisheries management.

东部尤其是太平洋蓝鳍金枪鱼

太平洋蓝鳍金枪鱼越过海洋迁徙的次数比以前认识到的要多 高市场价值刺激了太平洋蓝鳍金枪鱼（Thunnus orientalis，见照片）的广泛渔业，这种物种的寿命、商业价值和世代时间长，特别容易受到过度捕捞的影响（1 , 2). 今天，太平洋蓝鳍金枪鱼的数量估计占捕捞前水平的 2.6% (1)。然而，对其基本生活史的了解并不完整。最近的研究 (3, 4) 表明，人们误解了太平洋蓝鳍金枪鱼在北太平洋的基本分布。结果强调需要基本的运动生态信息来协助以科学为基础的渔业管理。
