Abstract

White seabream D. sargus (n = 991) were caught along the Eastern Mediterranean between September 2010 and April 2012. Total length ranged from 11 to 38 cm, represented age classes between 1 and 5 years. Total weight ranged from 12 to 840 gm. The scales were used to estimate the age. Age group (I) is dominant in the catch of D. sargus. Growth was supported using the back-calculation method.  The growth performance index (Φ) showed a relatively high growth. Length at first maturity (Lm) was 21.27 cm corresponding age (tm) 2.68 years. Length at first capture (Lc) was 18.1 cm corresponding age (tc) 2.08 years. So we have to increase the length at first capture to the length at first maturity in order to give fishes opportunity to spawn at first time at least.
