    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 <I>P. acarne</I> sampled were ranged from 7 cm (7.5 g) to 19.8 cm (137.5 g) with average 12.4&plusmn;0.06 cm FL (35.2&plusmn;0.57 g) while a total of 1127 <I>P. erythrinus</I> specimens were also ranged from 4.6 cm (1.8 g) to 22.3 cm (247.8 g) with average 13.1&plusmn;0.09 cm FL (50.8&plusmn;1.02 g). The maximal CPUE was found in Autumn (0.53&plusmn;0.14 kg h<SUP>-1</SUP>) for <I>P. acarne</I> while in Spring (1.29&plusmn;0.47 kg h<SUP>-1</SUP>) for <I>P. erythrinus</I>. The high exploitation rates (E = 0.65 year<SUP>-1</SUP> for <I>P. acarne</I> and E = 0.61 year<SUP>-1</SUP> for <I>P. erythrinus</I>) indicates the over-fishing on both Pagellus populations in the Aegean sea.
