To clarify the relationships between the survival period of newly hatched Pacific saury Cololabis saira which use only endogenous nutrition and water temperature, we observed the survival periods under starvation conditions at four temperatures (10, 15, 20 and 25°C). The starvation tolerance period was shortened with increasing temperature. This study suggests that newly hatched Pacific saury can survive for approximately 5-10 days (50% mortality period) without feeding in 10-25°C under non-predator conditions, but such an extended period of starvation is considered to affect subsequent growth and survival.
