The 2010 Deepwater Horizon oil spill impacted the northern Gulf of Mexico (GOM) during the spring spawning season of Atlantic bluefin tuna (BFT). Overlap between BFT spawning habitat and surface oil in the northern GOM was examined using satellite-derived estimates of oil coverage, and spawning habitat models. Results suggested that although eggs and larvae were likely impacted by oil-contaminated waters in the eastern GOM, high abundances of larvae were located elsewhere, especially in the western GOM. Overall, less than 10% of BFT spawning habitat was predicted to have been covered by surface oil, and less than 12% of larval BFT were predicted to have been located within contaminated waters in the northern GOM, on a weekly basis. Our results provide preliminary but important initial estimates of the effects of the spill on larval BFT mortality, as concern continues over the appropriate management responses to impacts of the spill.
2010 年深水地平线石油泄漏事件发生在春季大西洋蓝鳍金枪鱼（BFT）产卵季节，对墨西哥湾北部（GOM）造成了影响。利用卫星衍生的石油覆盖估计值和产卵栖息地模型，研究了 BFT 产卵栖息地与北部 GOM 表面石油之间的重叠情况。结果表明，尽管东部 GOM 的油污水域可能对鱼卵和幼鱼产生影响，但幼鱼的大量存在却在其他地方，尤其是在西部 GOM。总体而言，预计不到 10%的 BFT 产卵栖息地会被表面石油覆盖，每周只有不到 12%的幼鱼 BFT 会在北部 GOM 的受污染水域中被发现。我们的研究结果初步但重要地估计了泄漏事件对幼鱼 BFT 死亡率的影响，因为人们持续关注泄漏事件对适当管理应对措施的影响。
