Abstract

Abstract : We collected data on the age at maturity (tm ) and maximum reported age (tmax ) for 153 stocks of marine fishes in Turkey, belonging to 59 species, 24 families and 2 classes (Actinopterygii and Elasmobranchii). Among Actinopterygii tm had an average of 1.8 years (1 to 4 years) while among Elasmobranchii it had an average of 11.9 years (2 to 11.9 years). Overall, tmax ranged between two years (for Sarda sarda ) and 34 years (for Squalus acanthias ). Mean tmax was found to be 6.24 years for Actinopterygii and 10.11 years for Elasmobranchii. tm showed a positive linear correlation with tmax for both Actinopterygii and Elasmobranchii. Mean tm ⁄tmax did not differ significantly with sex within the Actinopterygii and Elasmobranchii. The ratio tm ⁄tmax was found to be significantly lower for Actinopterygii than for Elasmobranchii.
