Abstract

The possible role of feeding time on the synchronization of the molecular clock in the fish adrenal gland wasinvestigated. Goldfish acclimated to 12D:12L photoperiod received the daily ration of food at two times ofdaily cycle, the mid-light (ML) and mid-darkness (MD). The results reveal that the feeding time synchronizesclock genes in the adrenal gland, being these the molecular basis of biologic oscillator. Locomotor activityconfirm this synchronization, with a pronounced food anticipatory activity exhibited by both groups. Therhythmicity observed on circulating cortisol suggest this hormone is a rhythmic output of the biological clockin the adrenal gland of fish.
