• 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.
