Age was determined in the Alfonsino, Beryx splendens, by counting the opaque rings on the anti‐sulcal surface of left sagittae obtained from specimens, 15–43.5 cm fork length (FL), caught off the Azores. Females were from 1 to 12 years old and males were 1 to 9 years old. Von Bertalanffy (VB) growth equations were fitted to data obtained from age‐length keys, back calculation, and length‐frequency analyses. Gro...
The Alfonsino, Beryx splendens Lowe, 1834, is a demersal fish species that inhabits the continental slope (200-600 m depth) in the eastern Atlantic (Quero, 1984) and seamounts around the islands of Madeira, the Canaries and the Azores (Maul, 1986).
