Abstract: The daily basis of increment deposition in sagitta otoliths of laboratory and mesocosm reared (Odontesthes bonariensis) larvae was validated (Buenos Aires prov., Argentina). The timing of changes in rearing environment was recorded in otoliths by tetracycline marking. Results showed that increment deposition started at hatching and proceeded on a daily basis at least during the first two months of life. Thus, age and hatching date of O. bonariensis larvae can be easily determined by otolith reading within this period. This information will be useful to assess growth rate and mortality in extensive culture as well as in stock enhancement programs with this species.
