Abstract
This study was carried out by using experimental trawl surveys in Izmir bay (Aegean sea) with seasonal basis between 2007 and 2009. A total of 707 specimens of P. acarne sampled were ranged from 7 cm (7.5 g) to 19.8 cm (137.5 g) with average 12.4±0.06 cm FL (35.2±0.57 g) while a total of 1127 P. erythrinus specimens were also ranged from 4.6 cm (1.8 g) to 22.3 cm (247.8 g) with average 13.1±0.09 cm FL (50.8±1.02 g). The maximal CPUE was found in Autumn (0.53±0.14 kg h-1) for P. acarne while in Spring (1.29±0.47 kg h-1) for P. erythrinus. The high exploitation rates (E = 0.65 year-1 for P. acarne and E = 0.61 year-1 for P. erythrinus) indicates the over-fishing on both Pagellus populations in the Aegean sea.
