Abstract
In order to determine the nature of the relationships between otolith growth and somatic growth as they relate to previous growth history, largemouth bass (Micropterus salmoides) were injected with calcein to impart fluorescent marks on the otoliths on a periodic basis. Total lengths and weights were recorded at the times of injection. Fish were maintained either under a natural photoperiod or a 12L: 12D photoperiod. After thirteen months otoliths were removed and examined. The relationships between otolith growth, total length growth, and mass increase were explored. There were significant, but weak predictive relationships between otolith growth and total length growth, and between otolith growth and mass increase. Otolith and somatic growth relationships alone are not sufficient to provide detailed information on previous growth history for largemouth bass. The lack of seasonal photoperiod cues did ot affect these parameters.
