Pacific bluefin tuna populations are rebounding years ahead of schedule
After decades of overfishing pushed the species to a fraction of its historic abundance, aggressive international quotas and electronic monitoring have triggered a rapid recovery.
By the early 2010s, the Pacific bluefin tuna had become a global symbol of ecological collapse. Decades of industrial fishing had reduced the population to a small fraction of its historic levels, threatening both the ocean's food chain and one of the world's most lucrative commercial fisheries. The situation was so dire that many feared the species would never recover to sustainable levels.
