Summary | Biological database of Pagellus bogaraveo (blackspot seabream), Pagr pagrus (red porgy), Pagellus acarne (axillary bream), Diplodus sargus (white seabream) and Boops boops (striped bigeye). Reproduction of P. bogaraveo: length at first maturity, spawning period, fecun and hermaphroditism, were studied. Otoliths were used to determine the age and growth of P. bogaraveo: the occurrence of annuli on the otoliths was confirmed Maximum age of fish collected was 15 years and the parameters of the von Bertalanffy equation of growth in length were: Loo = 57.45, k = 0.102 and t0 = 1.13. The length-weight relationship was done. Virtual Population Analysis (VP) was done. |
