Bigeye tuna are of global economic importance and are the primary target species of Hawaii's most valuable commercial fishery. Due to their high commercial value, bigeye tuna are relatively well studied and routinely assessed. Larval and adult bigeye surveys have been conducted for many years and are supported by ongoing research on their physiology and life history. Yet, modeling stock dynamics and estimating future catch rates remain challenging. Here, we show that an appropriately lagged measure of phytoplankton size is a robust predictor of catch rates in Hawaii's bigeye tuna fishery with a forecast window of four years. We present a fishery‐independent tool with the potential to improve stock assessments, aid dynamic fisheries management, and allow Hawaii's commercial longline fishing industry to better plan for the future.

向金枪鱼招募的环境预测者迈进

大眼金枪鱼具有全球经济重要性，是夏威夷最有价值的商业渔业的主要目标物种。由于大眼金枪鱼具有很高的商业价值，因此对其进行了比较深入的研究和常规评估。幼虫和成年大眼调查已经进行了多年，并得到了有关其生理和生活史的持续研究的支持。然而，对种群动态进行建模并估算未来的捕获率仍然充满挑战。在这里，我们表明，对浮游植物大小的适当滞后度量是夏威夷大眼金枪鱼渔业捕捞率的有力预测指标，预测窗口为四年。我们提供了一种独立于渔业的工具，可以改善种群评估，辅助动态渔业管理，并使夏威夷的商业延绳钓渔业更好地规划未来。
