In this study, ultrasonographic examination was performed thrice, 15 days apart, on juvenile European sea bass Dicentrarchus labrax, from 330 to 360 days of age, to assess the size and the morphology of male and female. Results have proved this method as a suitable and non-invasive procedure to assess sexual differentiation.
