Résumé
Reproduction of the blackspot seabream, Pagellus bogaraveo (Brünnich, 1768), was studied in Azorean waters. This species is characterised by protandric hermaphrodism. Length at first maturity averages 27.7 cm for males and 34.6 cm for females. Macro- and microscopic examination of gonads and gonadosomatic index indicated that spawning occurs once a year between January and April with peak activity in February and March. The length-fecundity equation is: F = 1028.44e0.15L
