Abstract [Özet]:
Specimens of European hake were collected by a traditional demersal trawl between July 2004 and June 2007 from İzmir Bay, Central Aegean Sea. A total of 2108 individuals were sampled during the study and the female:male sex ratio of the stock was 1:0.89. The length–weight relationship was W=0.00341L3.24 (R2=0.994) for all individuals. A high gonadosomatic index was evident over most of the year but it was minimal from August to October. The estimated age composition was 1–5 years; the length and weight at infinity were calculated as L=54.53 cm and W=1455.77 g respectively. In addition, growth coefficient was found to be k=0.315 y-1 and t0=20.223 y (R2=0.99). Total mortality ratio of the stock was calculated as Z=1.539 y-1, while natural and fishing based mortality ratio were estimated as M=0.579 y-1 and F=0.959 y-1 respectively, with the exploitation ratio (E) of the stock estimated to be 0.624.
