In general, there is a lack of exhaustive studies on Atlantic albacore sexual maturity. Lam Hoai (1970) estimated that first sexual maturity is reached at 75-85 cm FL, while Hayasi et al (1972) assume sexual maturity occurs at 85 cm (around 13 kg). At present, for North and South Atlantic albacore it is assumed that 50% of the fish are mature at 90 cm or Age 5 (Bard 1981), and at 62 cm for Mediterranean albacore (Table 3, Arena et al 1980).
