AB  - Age and growth of chub mackerel, <I>Scomber japonicus,</I> were studied in the Izmir Bay (Aegean Sea). A total of 520 specimens were collected during the period November 1997 to October 1998 from purse-seine boats operating in the Izmir Bay. Fork lengths ranged between 12.5 and 27.2 cm. Overall female: Male ratio was 1:1.13. Age distribution of the samples ranged from I to IV years (otolith readings). Chub mackerel grew positive allometrically (b = 3.40±0.05 at 95% confidence level). Growth parameters of the population were: L<SUB> </SUB> = 27.15 cm, K  =  0.20  year <SUP>1</SUP>,  t<SUB>0 </SUB> =  -0.48  years  for  females;  L<SUB>8 </SUB> =  29.64  cm, K = 0.23 year <SUP>1</SUP>, t<SUB>0 </SUB>= -0.39 years for males and L<SUB>8</SUB> = 29.87 cm, K = 0.20 year <SUP>1</SUP>, t<SUB>0 </SUB>= -0.36 years for both sexes. Growth index ( `) was calculated as 2.29, 2.31 and 2.25, respectively for females,  males and sexes combined.
