Abstract

The annual catch of bogue, Boops boops, in Egypt decreased from about 4000 MT to be 2000 MT in last 10 years. The present study provided information on the fisheries biology of B. boops, from Egyptian Mediterranean waters for management purpose. Monthly random samples of total 1367 specimens were collected from three landing sites front Alexandra during 2018. Results showed that, the total length of B. boops varied from 9.3 to 23 cm, while the total weight ranged between 7.4 and 133.1 g. The length-weight relationship revealed that “b" value (2.96) is indicating a tendency towards isometric growth with statistically highly significant coefficient. The longevity of B. boops was estimated to be 4 years and age groups I+ and II+ were the most abundant in the catch constituting more than 85%. The length at first capture and first maturity was 12.5 and 13.2 cm respectively. The mortalities rates were 0.671, 1.589 and 2.26 y-1 for natural, fishing and total mortalities, respectively. The bogue stocks in the Mediterranean waters front Alexandria was exposed to over exploitation (E= 0.70). For fisheries management, some measures were proposed for stock maintenance, fisheries development and catch sustainability.
