Abstract(s)
The rocky inter-tidal habitat is a harsh and fluctuating environment, subject tofrequent disturbances. Field observations of juvenile white seabream Diplodussargus in inter-tidal rocky habitats were conducted to analyse the spatial distri-bution and feeding activity of this species in relation to the tidal cycle. Thedepth at which fish were observed did not change in most tidal phases whilefeeding activity changed with tidal level, showing the occurrence of tidal migra-tions and that feeding may be limited by habitat availability in shallow watersand thus be dependent on tidal changes. The present results show the exploita-tion of available feeding areas in the rocky inter-tidal by juvenile white seab-ream, which corroborates the importance of these habitats for the firstdevelopmental stages of this fish species.
