Although Pacific bluefin tuna (PBF) has larger body density than the sea water, their swimming ability is quite low during the early larval stage. We observed their swimming behavior and investigated how PBF control their swimming direction and depth by developing their swimming ability, and how they develop their escaping behavior. PBF larvae started to improve their swimming ability from 3 days post hatching and control their swimming depth by aggressive swimming in a horizontal direction. Their turning movement was improved around 20 days post hatching, which coincides with the metamorphosis from the larvae to juvenile.

虽然太平洋蓝鳍金枪鱼（PBF）的体密度比海水大，但其幼虫早期的游泳能力很低。我们观察了它们的游泳行为，研究了PBF如何通过发展它们的游泳能力来控制它们的游泳方向和深度，以及它们如何发展它们的逃跑行为。PBF幼虫从孵化后3 d开始提高游泳能力，并通过向水平方向积极游动来控制游泳深度。在孵化后20天左右，它们的翻身运动有所改善，这与幼虫向幼鱼的蜕变相吻合。
