秋刀鱼是一种小型（最大 35 厘米 SL）中上层鱼类，夏季（6 月至 8 月）在食物丰富的亚北极水域（10–12 °C）中活跃摄食，冬季（12 月至 4 月）在食物贫乏的亚热带水域（20–22 °C）中产卵。检查了 8 月至 2 月 30 厘米标准化鱼的蛋白质、脂质和能量含量的变化。觅食季节积累的身体储备丰富，大部分在南迁过程中消耗殆尽，到活跃产卵季节几乎耗尽。由此可见，分配给产蛋的能量大部分来自于产卵季节消耗的食物能量。
Pacific saury is a small (up to 35 cm SL) pelagic fish, feeding actively in the food-rich sub-arctic water (10–12 °C) during summer (June – August) and spawning in the food-poor sub-tropical water (20–22 °C) during winter (December – April). Changes in protein, lipid, and energy content for 30 cm standardized fish from August to February were examined. Accumulated body reserves were abundant in the feeding season, most of them being expended during southward migration, and almost exhausted in the active spawning season. Thus it is indicated that most of the allocated energy to egg production was derived from the energy of food consumed during spawning season.
