An individual's growth opportunity may be influenced by the date on which it wasborn. To examine the effects of birth date on growth in juvenile (Age 0+ ) white-spotted charr Salvelinus leucomaenis, individual birth dates were identified by counting the daily growth increments in the otolith. Significant linear relationships were found between fork length at catch and birth date; early-born individuals tended to be larger than late-born ones at a given time. About one quarter or half of the variability observed in fork length could be explained by birth date variation. Differences of birth date among individuals within a cohort may have a significant influence on later stages of life history, such as age at seaward migration.
