In this review, we collected data on the age at maturity (t(m)) and maximum reported age (t(max)) for 235 stocks of Mediterranean marine fishes, belonging to 82 species, 37 families, 12 orders and 2 classes (Actinopterygii and Elasmobranchii). Among Actinopterygii (mean t(m) +/- SD = 2.20 +/- 1.43 y, n = 215), t(m) ranged from 0.3 y, for the common goby Pomatoschistus microps, to 12 y, for the dusky grouper Epinephelus marginatus, while among Elasmobranchii (mean t(m) +/- SD = 5.94 +/- 2.47 y, n = 20), t(m) ranged between 2.7 y, for brown ray Raja miraletus, and 12 y for the picked dogfish Squalus acanthias. Overall, t(max) ranged between 1 y, for the transparent goby Aphia minuta, and 70 y, for the wreckfish Polyprion americanus. Mean t(max) of Actinopterygii (t(max) +/- SD = 10.14 +/- 9.42 y) was lower than that of Elasmobranchii (t(max) +/- SD = 14.05 +/- 8.47 y); t(m) exhibited a strong positive linear relation with t(max) for both Actinopterygii (logt(m) = 0.58 x logt(max) - 0.25, r(2) = 0.51, P < 0.001) and Elasmobranchii (logt(m) = 0.67 x logt(max) - 0.006, r(2) = 0.51, P = 0.007). Mean t(m)/t(max) did not differ significantly with sex within Actinopterygii (ANOVA: F = 0.27, P = 0.60, n = 90; females: mean +/- SD = 0.276 +/- 0.143; males: mean +/- SD = 0.265 +/- 0.138) and Elasmobranchii (ANOVA: F = 1.44, P = 0.25, n = 10; females: mean +/- SD = 0.499 +/- 0.166; males: mean +/- SD = 0.418 +/- 0.133). Finally, the dimensionless ratio t(m)/t(max) was significantly lower (ANOVA: F = 31.04, P < 0.001) for Actinopterygii (mean +/- SD = 0.270 +/- 0.135, n = 180) than for Elasmobranchii, (mean +/- SD = 0.458 +/- 0.152, n = 20), when stocks with combined sexes were excluded from the analysis.
