Abstract

The behaviour of the prelarval stages of Sparus auratus, Diplodus vulgaris and Diplodus sargus was studied in 570-l tanks at a temperature of 19°C. The different stages in swimming from hatching to the age of 4 days are as follows; period of dominating immobility (1st day); passive vertical migration (2nd day); first oblique swimming (3rd day); first horizontal swimming (4th day). The different speeds of swimming and the distances covered are calculated; the specific differences are mentioned. The predation training period is described and food selectivity at this stage is demonstrated. Aquacultural implications are discussed. © 1982.
