Abstract

Schooling was first observed at 25-27 days after hatching (26. 2-33. 8 mm, total length) in the Pacific bluefin tuna Thunnus orientalis. At this time, the mode of swimming changed from intermittent sprinting to continuous cruising, and this allowed the fish to adjust to an inertial hydrodynamic environment.

摘要

在太平洋蓝鳍金枪鱼（Thunnus orientalis）孵化后 25-27 天（全长 26.2-33.8 毫米）时首次观察到 schooling 行为。此时，游泳模式从间歇性冲刺转变为连续巡游，这使鱼类能够适应惯性水动力环境。
