ResumenIn the present paper the age of albacore (Germo alalunga (Bonnaterre)) of NW. Spanish coasts is studied using concentric marks on the centra of vertebrae as indicators of the age of the fish. The relationship of body length to vertebral radius is rectilinear. There is good agreement between the estimated average length for the III, IV, V and VI groups found by the author and those of PARTLO(1955), but there exists also a difference of about one year in the calculated average length and that observed by both authors. The author believes that the vertebral annulus is probably laid down later at a certain distance from the edge of the vertebral centrum. The author reaches the conclusion that the mean length of the albacore (males and females together) is aproximately: 17-18 cm in its 1rst year 31-32 » ...... 2nd " 44-45 » ...... 3rd " 56-57 » ....... 4th " 69-70 » ...... 5th " 81-82 ...... 6th " 91-93 » ...... 7th >>
