Özet
Growth characteristics and age structure of 439 specimens of Dentex maroccanus captured by fishermen in December 2012 – March 2014 from Izmir Bay, Aegean Sea, Turkey, were studied. Of the 346 fish specimens whose sex was determined, 206 were female and 140 were male. The length-weight relationships of females, males and the entire population were described by the equations W=0.0194*L2.924, W=0.0269*L2.789 and W=0.0228*L2.856, respectively. The highest condition factor of the population was 1.59 and was recorded in spring. According to the age identification using otoliths, the population was in the age range of I–V. With 39%, the II age group had the highest ratio. The infinite length value for the entire population was calculated to be L? =27.43*(1–e-0.21 (t-(-0.68))). The growth performance index was 2.20. © 2020 Bulgarian Academy of Sciences. All rights reserved.
