| Abstract: | 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. |
